continuous integration. Buildkite builds need to be authorised by a
maintainer. If your change breaks the build, this will be shown in GitHub, so
please keep an eye on the pull request for feedback.
To run unit tests in a local development environment, you can use:
- ``tox -e py35`` (requires tox to be installed by ``pip install tox``)
for SQLite-backed Synapse on Python 3.5.
- ``tox -e py36`` for SQLite-backed Synapse on Python 3.6.
- ``tox -e py36-postgres`` for PostgreSQL-backed Synapse on Python 3.6
(requires a running local PostgreSQL with access to create databases).
- ``./test_postgresql.sh`` for PostgreSQL-backed Synapse on Python 3.5
(requires Docker). Entirely self-contained, recommended if you don't want to
set up PostgreSQL yourself.
Docker images are available for running the integration tests (SyTest) locally,
see the `documentation in the SyTest repo

information.
We use `Jenkins <http://matrix.org/jenkins>`_ and

integration. All pull requests to synapse get automatically tested by Travis;
the Jenkins builds require an adminstrator to start them. If your change

* ``bugfix``.
* ``docker`` (for updates to the Docker image).
* ``doc`` (for updates to the documentation).
* ``removal`` (also used for deprecations).
* ``misc`` (for internal-only changes).
The content of the file is your changelog entry, which should be a short
description of your change in the same style as the rest of our `changelog
<https://github.com/matrix-org/synapse/blob/master/CHANGES.md>`_. The file can
contain Markdown formatting, and should end with a full stop ('.') for
consistency.
Adding credits to the changelog is encouraged, we value your
contributions and would like to have you shouted out in the release notes!
For example, a fix in PR #1234 would have its changelog entry in
``changelog.d/1234.bugfix``, and contain content like "The security levels of
Florbs are now validated when recieved over federation. Contributed by Jane
Matrix.".
Debian changelog
----------------
Changes which affect the debian packaging files (in ``debian``) are an
exception.
In this case, you will need to add an entry to the debian changelog for the
next release. For this, run the following command::
dch
This will make up a new version number (if there isn't already an unreleased
version in flight), and open an editor where you can add a new changelog entry.
(Our release process will ensure that the version number and maintainer name is
corrected for the release.)
If your change affects both the debian packaging *and* files outside the debian
directory, you will need both a regular newsfragment *and* an entry in the
debian changelog. (Though typically such changes should be submitted as two
separate pull requests.)
For example, a fix for a bug reported in #1234 would have its
changelog entry in ``changelog.d/1234.bugfix``, and contain content
like "The security levels of Florbs are now validated when
recieved over federation. Contributed by Jane Matrix".

# Choosing your server name
It is important to choose the name for your server before you install Synapse,
because it cannot be changed later.
The server name determines the "domain" part of user-ids for users on your
server: these will all be of the format `@user:my.domain.name`. It also
determines how other matrix servers will reach yours for federation.
For a test configuration, set this to the hostname of your server. For a more
production-ready setup, you will probably want to specify your domain
(`example.com`) rather than a matrix-specific hostname here (in the same way
that your email address is probably `user@example.com` rather than
`user@email.example.com`) - but doing so may require more advanced setup: see
[Setting up Federation](docs/federate.md).
# Installing Synapse
## Installing from source
(Prebuilt packages are available for some platforms - see [Prebuilt packages](#prebuilt-packages).)
System requirements:
- POSIX-compliant system (tested on Linux & OS X)
- Python 3.5, 3.6, 3.7, or 2.7
- At least 1GB of free RAM if you want to join large public rooms like #matrix:matrix.org
Synapse is written in Python but some of the libraries it uses are written in
C. So before we can install Synapse itself we need a working C compiler and the
header files for Python C extensions. See [Platform-Specific
Instructions](#platform-specific-instructions) for information on installing
these on various platforms.
To install the Synapse homeserver run:
```
mkdir -p ~/synapse
virtualenv -p python3 ~/synapse/env
source ~/synapse/env/bin/activate
pip install --upgrade pip
pip install --upgrade setuptools
pip install matrix-synapse
```
This will download Synapse from [PyPI](https://pypi.org/project/matrix-synapse)
and install it, along with the python libraries it uses, into a virtual environment
under `~/synapse/env`. Feel free to pick a different directory if you
prefer.
This Synapse installation can then be later upgraded by using pip again with the
update flag:
```
source ~/synapse/env/bin/activate
pip install -U matrix-synapse
```
Before you can start Synapse, you will need to generate a configuration
file. To do this, run (in your virtualenv, as before)::
```
cd ~/synapse
python -m synapse.app.homeserver \
--server-name my.domain.name \
--config-path homeserver.yaml \
--generate-config \
--report-stats=[yes|no]
```
... substituting an appropriate value for `--server-name`.
This command will generate you a config file that you can then customise, but it will
also generate a set of keys for you. These keys will allow your Home Server to
identify itself to other Home Servers, so don't lose or delete them. It would be
wise to back them up somewhere safe. (If, for whatever reason, you do need to
change your Home Server's keys, you may find that other Home Servers have the
old key cached. If you update the signing key, you should change the name of the
key in the `<server name>.signing.key` file (the second word) to something
different. See the
[spec](https://matrix.org/docs/spec/server_server/latest.html#retrieving-server-keys)
for more information on key management.)
To actually run your new homeserver, pick a working directory for Synapse to
run (e.g. `~/synapse`), and::
cd ~/synapse
source env/bin/activate
synctl start
### Platform-Specific Instructions
#### Debian/Ubuntu/Raspbian
Installing prerequisites on Ubuntu or Debian:
```
sudo apt-get install build-essential python3-dev libffi-dev \
python-pip python-setuptools sqlite3 \
libssl-dev python-virtualenv libjpeg-dev libxslt1-dev
```
#### ArchLinux
Installing prerequisites on ArchLinux:
```
sudo pacman -S base-devel python python-pip \
python-setuptools python-virtualenv sqlite3
```
#### CentOS/Fedora
Installing prerequisites on CentOS 7 or Fedora 25:
```
sudo yum install libtiff-devel libjpeg-devel libzip-devel freetype-devel \
lcms2-devel libwebp-devel tcl-devel tk-devel redhat-rpm-config \
python-virtualenv libffi-devel openssl-devel
sudo yum groupinstall "Development Tools"
```
#### Mac OS X
Installing prerequisites on Mac OS X:
```
xcode-select --install
sudo easy_install pip
sudo pip install virtualenv
brew install pkg-config libffi
```
#### OpenSUSE
Installing prerequisites on openSUSE:
```
sudo zypper in -t pattern devel_basis
sudo zypper in python-pip python-setuptools sqlite3 python-virtualenv \
python-devel libffi-devel libopenssl-devel libjpeg62-devel
```
#### OpenBSD
Installing prerequisites on OpenBSD:
```
doas pkg_add python libffi py-pip py-setuptools sqlite3 py-virtualenv \
libxslt jpeg
```
There is currently no port for OpenBSD. Additionally, OpenBSD's security
settings require a slightly more difficult installation process.
XXX: I suspect this is out of date.
1. Create a new directory in `/usr/local` called `_synapse`. Also, create a
new user called `_synapse` and set that directory as the new user's home.
This is required because, by default, OpenBSD only allows binaries which need
write and execute permissions on the same memory space to be run from
`/usr/local`.
2. `su` to the new `_synapse` user and change to their home directory.
3. Create a new virtualenv: `virtualenv -p python2.7 ~/.synapse`
4. Source the virtualenv configuration located at
`/usr/local/_synapse/.synapse/bin/activate`. This is done in `ksh` by
using the `.` command, rather than `bash`'s `source`.
5. Optionally, use `pip` to install `lxml`, which Synapse needs to parse
webpages for their titles.
6. Use `pip` to install this repository: `pip install matrix-synapse`
7. Optionally, change `_synapse`'s shell to `/bin/false` to reduce the
chance of a compromised Synapse server being used to take over your box.
After this, you may proceed with the rest of the install directions.
#### Windows
If you wish to run or develop Synapse on Windows, the Windows Subsystem For
Linux provides a Linux environment on Windows 10 which is capable of using the
Debian, Fedora, or source installation methods. More information about WSL can
be found at https://docs.microsoft.com/en-us/windows/wsl/install-win10 for
Windows 10 and https://docs.microsoft.com/en-us/windows/wsl/install-on-server
for Windows Server.
### Troubleshooting Installation
XXX a bunch of this is no longer relevant.
Synapse requires pip 8 or later, so if your OS provides too old a version you
may need to manually upgrade it::
sudo pip install --upgrade pip
Installing may fail with `Could not find any downloads that satisfy the requirement pymacaroons-pynacl (from matrix-synapse==0.12.0)`.
You can fix this by manually upgrading pip and virtualenv::
sudo pip install --upgrade virtualenv
You can next rerun `virtualenv -p python3 synapse` to update the virtual env.
Installing may fail during installing virtualenv with `InsecurePlatformWarning: A true SSLContext object is not available. This prevents urllib3 from configuring SSL appropriately and may cause certain SSL connections to fail. For more information, see https://urllib3.readthedocs.org/en/latest/security.html#insecureplatformwarning.`
You can fix this by manually installing ndg-httpsclient::
pip install --upgrade ndg-httpsclient
Installing may fail with `mock requires setuptools>=17.1. Aborting installation`.
You can fix this by upgrading setuptools::
pip install --upgrade setuptools
If pip crashes mid-installation for reason (e.g. lost terminal), pip may
refuse to run until you remove the temporary installation directory it
created. To reset the installation::
rm -rf /tmp/pip_install_matrix
pip seems to leak *lots* of memory during installation. For instance, a Linux
host with 512MB of RAM may run out of memory whilst installing Twisted. If this
happens, you will have to individually install the dependencies which are
failing, e.g.::
pip install twisted
## Prebuilt packages
As an alternative to installing from source, prebuilt packages are available
for a number of platforms.
### Docker images and Ansible playbooks
There is an offical synapse image available at
https://hub.docker.com/r/matrixdotorg/synapse which can be used with
the docker-compose file available at [contrib/docker](contrib/docker). Further information on
this including configuration options is available in the README on
hub.docker.com.
Alternatively, Andreas Peters (previously Silvio Fricke) has contributed a
Dockerfile to automate a synapse server in a single Docker image, at
https://hub.docker.com/r/avhost/docker-matrix/tags/
Slavi Pantaleev has created an Ansible playbook,
which installs the offical Docker image of Matrix Synapse
along with many other Matrix-related services (Postgres database, riot-web, coturn, mxisd, SSL support, etc.).
For more details, see
https://github.com/spantaleev/matrix-docker-ansible-deploy
### Debian/Ubuntu
#### Matrix.org packages
Matrix.org provides Debian/Ubuntu packages of the latest stable version of
Synapse via https://packages.matrix.org/debian/. They are available for Debian
9 (Stretch), Ubuntu 16.04 (Xenial), and later. To use them:
```
sudo apt install -y lsb-release wget apt-transport-https
sudo wget -O /usr/share/keyrings/matrix-org-archive-keyring.gpg https://packages.matrix.org/debian/matrix-org-archive-keyring.gpg
echo "deb [signed-by=/usr/share/keyrings/matrix-org-archive-keyring.gpg] https://packages.matrix.org/debian/ $(lsb_release -cs) main" |
sudo tee /etc/apt/sources.list.d/matrix-org.list
sudo apt update
sudo apt install matrix-synapse-py3
```
**Note**: if you followed a previous version of these instructions which
recommended using `apt-key add` to add an old key from
`https://matrix.org/packages/debian/`, you should note that this key has been
revoked. You should remove the old key with `sudo apt-key remove
C35EB17E1EAE708E6603A9B3AD0592FE47F0DF61`, and follow the above instructions to
update your configuration.
The fingerprint of the repository signing key (as shown by `gpg
/usr/share/keyrings/matrix-org-archive-keyring.gpg`) is
`AAF9AE843A7584B5A3E4CD2BCF45A512DE2DA058`.
#### Downstream Debian/Ubuntu packages
For `buster` and `sid`, Synapse is available in the Debian repositories and
it should be possible to install it with simply:
```
sudo apt install matrix-synapse
```
There is also a version of `matrix-synapse` in `stretch-backports`. Please see
the [Debian documentation on
backports](https://backports.debian.org/Instructions/) for information on how
to use them.
We do not recommend using the packages in downstream Ubuntu at this time, as
they are old and suffer from known security vulnerabilities.
### Fedora
Synapse is in the Fedora repositories as `matrix-synapse`:
```
sudo dnf install matrix-synapse
```
Oleg Girko provides Fedora RPMs at
https://obs.infoserver.lv/project/monitor/matrix-synapse
### OpenSUSE
Synapse is in the OpenSUSE repositories as `matrix-synapse`:
```
sudo zypper install matrix-synapse
```
### SUSE Linux Enterprise Server
Unofficial package are built for SLES 15 in the openSUSE:Backports:SLE-15 repository at
https://download.opensuse.org/repositories/openSUSE:/Backports:/SLE-15/standard/
### ArchLinux
The quickest way to get up and running with ArchLinux is probably with the community package
https://www.archlinux.org/packages/community/any/matrix-synapse/, which should pull in most of
the necessary dependencies.
pip may be outdated (6.0.7-1 and needs to be upgraded to 6.0.8-1 ):
```
sudo pip install --upgrade pip
```
If you encounter an error with lib bcrypt causing an Wrong ELF Class:
ELFCLASS32 (x64 Systems), you may need to reinstall py-bcrypt to correctly
compile it under the right architecture. (This should not be needed if
installing under virtualenv):
```
sudo pip uninstall py-bcrypt
sudo pip install py-bcrypt
```
### FreeBSD
Synapse can be installed via FreeBSD Ports or Packages contributed by Brendan Molloy from:
- Ports: `cd /usr/ports/net-im/py-matrix-synapse && make install clean`
- Packages: `pkg install py27-matrix-synapse`
### NixOS
Robin Lambertz has packaged Synapse for NixOS at:
https://github.com/NixOS/nixpkgs/blob/master/nixos/modules/services/misc/matrix-synapse.nix
# Setting up Synapse
Once you have installed synapse as above, you will need to configure it.
## TLS certificates
The default configuration exposes a single HTTP port: http://localhost:8008. It
is suitable for local testing, but for any practical use, you will either need
to enable a reverse proxy, or configure Synapse to expose an HTTPS port.
For information on using a reverse proxy, see
[docs/reverse_proxy.rst](docs/reverse_proxy.rst).
To configure Synapse to expose an HTTPS port, you will need to edit
`homeserver.yaml`, as follows:
* First, under the `listeners` section, uncomment the configuration for the
TLS-enabled listener. (Remove the hash sign (`#`) at the start of
each line). The relevant lines are like this:
```
- port: 8448
type: http
tls: true
resources:
- names: [client, federation]
```
* You will also need to uncomment the `tls_certificate_path` and
`tls_private_key_path` lines under the `TLS` section. You can either
point these settings at an existing certificate and key, or you can
enable Synapse's built-in ACME (Let's Encrypt) support. Instructions
for having Synapse automatically provision and renew federation
certificates through ACME can be found at [ACME.md](docs/ACME.md). If you
are using your own certificate, be sure to use a `.pem` file that includes
the full certificate chain including any intermediate certificates (for
instance, if using certbot, use `fullchain.pem` as your certificate, not
`cert.pem`).
For a more detailed guide to configuring your server for federation, see
[federate.md](docs/federate.md)
## Email
It is desirable for Synapse to have the capability to send email. For example,
this is required to support the 'password reset' feature.
To configure an SMTP server for Synapse, modify the configuration section
headed ``email``, and be sure to have at least the ``smtp_host``, ``smtp_port``
and ``notif_from`` fields filled out. You may also need to set ``smtp_user``,
``smtp_pass``, and ``require_transport_security``.
If Synapse is not configured with an SMTP server, password reset via email will
be disabled by default.
## Registering a user
You will need at least one user on your server in order to use a Matrix
client. Users can be registered either via a Matrix client, or via a
commandline script.
To get started, it is easiest to use the command line to register new
users. This can be done as follows:
```
$ source ~/synapse/env/bin/activate
$ synctl start # if not already running
$ register_new_matrix_user -c homeserver.yaml http://localhost:8008
New user localpart: erikj
Password:
Confirm password:
Make admin [no]:
Success!
```
This process uses a setting `registration_shared_secret` in
`homeserver.yaml`, which is shared between Synapse itself and the
`register_new_matrix_user` script. It doesn't matter what it is (a random
value is generated by `--generate-config`), but it should be kept secret, as
anyone with knowledge of it can register users, including admin accounts,
on your server even if `enable_registration` is `false`.
## Setting up a TURN server
For reliable VoIP calls to be routed via this homeserver, you MUST configure
a TURN server. See [docs/turn-howto.rst](docs/turn-howto.rst) for details.
## URL previews
Synapse includes support for previewing URLs, which is disabled by default. To
turn it on you must enable the `url_preview_enabled: True` config parameter
and explicitly specify the IP ranges that Synapse is not allowed to spider for
previewing in the `url_preview_ip_range_blacklist` configuration parameter.
This is critical from a security perspective to stop arbitrary Matrix users
spidering 'internal' URLs on your network. At the very least we recommend that
your loopback and RFC1918 IP addresses are blacklisted.
This also requires the optional lxml and netaddr python dependencies to be
installed. This in turn requires the libxml2 library to be available - on
Debian/Ubuntu this means `apt-get install libxml2-dev`, or equivalent for
your OS.

pip install --upgrade pip
pip install --upgrade setuptools
pip install https://github.com/matrix-org/synapse/tarball/master
This installs synapse, along with the libraries it uses, into a virtual

if you prefer.
In case of problems, please see the _`Troubleshooting` section below.
There is an offical synapse image available at
https://hub.docker.com/r/matrixdotorg/synapse/tags/ which can be used with
the docker-compose file available at `contrib/docker <contrib/docker>`_. Further information on
this including configuration options is available in the README on
hub.docker.com.
Alternatively, Andreas Peters (previously Silvio Fricke) has contributed a
Dockerfile to automate a synapse server in a single Docker image, at
https://hub.docker.com/r/avhost/docker-matrix/tags/
Also, Martin Giess has created an auto-deployment process with vagrant/ansible,
tested with VirtualBox/AWS/DigitalOcean - see
https://github.com/EMnify/matrix-synapse-auto-deploy
for details.
Configuring synapse
-------------------
Before you can start Synapse, you will need to generate a configuration
file. To do this, run (in your virtualenv, as before)::
cd ~/.synapse
python -m synapse.app.homeserver \
--server-name my.domain.name \
--config-path homeserver.yaml \
--generate-config \
--report-stats=[yes|no]
... substituting an appropriate value for ``--server-name``. The server name
determines the "domain" part of user-ids for users on your server: these will
all be of the format ``@user:my.domain.name``. It also determines how other
matrix servers will reach yours for `Federation`_. For a test configuration,
set this to the hostname of your server. For a more production-ready setup, you
will probably want to specify your domain (``example.com``) rather than a
matrix-specific hostname here (in the same way that your email address is
probably ``user@example.com`` rather than ``user@email.example.com``) - but
doing so may require more advanced setup - see `Setting up
Federation`_. Beware that the server name cannot be changed later.
This command will generate you a config file that you can then customise, but it will
also generate a set of keys for you. These keys will allow your Home Server to
identify itself to other Home Servers, so don't lose or delete them. It would be
wise to back them up somewhere safe. (If, for whatever reason, you do need to
change your Home Server's keys, you may find that other Home Servers have the
old key cached. If you update the signing key, you should change the name of the
key in the ``<server name>.signing.key`` file (the second word) to something
different. See `the spec`__ for more information on key management.)
.. __: `key_management`_
The default configuration exposes two HTTP ports: 8008 and 8448. Port 8008 is
configured without TLS; it should be behind a reverse proxy for TLS/SSL
termination on port 443 which in turn should be used for clients. Port 8448
is configured to use TLS with a self-signed certificate. If you would like
to do initial test with a client without having to setup a reverse proxy,
you can temporarly use another certificate. (Note that a self-signed
certificate is fine for `Federation`_). You can do so by changing
``tls_certificate_path``, ``tls_private_key_path`` and ``tls_dh_params_path``
in ``homeserver.yaml``; alternatively, you can use a reverse-proxy, but be sure
to read `Using a reverse proxy with Synapse`_ when doing so.
Apart from port 8448 using TLS, both ports are the same in the default
configuration.
Registering a user
------------------
You will need at least one user on your server in order to use a Matrix
client. Users can be registered either `via a Matrix client`__, or via a
commandline script.
.. __: `client-user-reg`_
To get started, it is easiest to use the command line to register new users::
$ source ~/.synapse/bin/activate
$ synctl start # if not already running
$ register_new_matrix_user -c homeserver.yaml https://localhost:8448
New user localpart: erikj
Password:
Confirm password:
Make admin [no]:
Success!
This process uses a setting ``registration_shared_secret`` in
``homeserver.yaml``, which is shared between Synapse itself and the
``register_new_matrix_user`` script. It doesn't matter what it is (a random
value is generated by ``--generate-config``), but it should be kept secret, as
anyone with knowledge of it can register users on your server even if
``enable_registration`` is ``false``.
Setting up a TURN server
------------------------
For reliable VoIP calls to be routed via this homeserver, you MUST configure
a TURN server. See `<docs/turn-howto.rst>`_ for details.
IPv6
----
As of Synapse 0.19 we finally support IPv6, many thanks to @kyrias and @glyph
for providing PR #1696.
However, for federation to work on hosts with IPv6 DNS servers you **must**

for details. We can't make Synapse depend on Twisted 17.1 by default
yet as it will break most older distributions (see https://github.com/matrix-org/synapse/pull/1909)
so if you are using operating system dependencies you'll have to install your
own Twisted 17.1 package via pip or backports etc.
If you're running in a virtualenv then pip should have installed the newest
Twisted automatically, but if your virtualenv is old you will need to manually
upgrade to a newer Twisted dependency via:
pip install Twisted>=17.1.0
Running Synapse
===============
To actually run your new homeserver, pick a working directory for Synapse to
run (e.g. ``~/.synapse``), and::
cd ~/.synapse
source ./bin/activate
synctl start
Connecting to Synapse from a client
===================================
The easiest way to try out your new Synapse installation is by connecting to it
from a web client.
from a web client. The easiest option is probably the one at
https://riot.im/app. You will need to specify a "Custom server" when you log on
or register: set this to ``https://domain.tld`` if you setup a reverse proxy
following the recommended setup, or ``https://localhost:8448`` - remember to specify the
port (``:8448``) if not ``:443`` unless you changed the configuration. (Leave the identity
server as the default - see `Identity servers`_.)
Unless you are running a test instance of Synapse on your local machine, in
general, you will need to enable TLS support before you can successfully
connect from a client: see `<INSTALL.md#tls-certificates>`_.
An easy way to get started is to login or register via Riot at
https://riot.im/app/#/login or https://riot.im/app/#/register respectively.
You will need to change the server you are logging into from ``matrix.org``
and instead specify a Homeserver URL of ``https://<server_name>:8448``
(or just ``https://<server_name>`` if you are using a reverse proxy).
(Leave the identity server as the default - see `Identity servers`_.)
If you prefer to use another client, refer to our
`client breakdown <https://matrix.org/docs/projects/clients-matrix>`_.
If using port 8448 you will run into errors until you accept the self-signed
certificate. You can easily do this by going to ``https://localhost:8448``
directly with your browser and accept the presented certificate. You can then
go back in your web client and proceed further.
If all goes well you should at least be able to log in, create a room, and
start sending messages.
(The homeserver runs a web client by default at https://localhost:8448/, though
as of the time of writing it is somewhat outdated and not really recommended -

Platform-Specific Instructions
==============================
Debian
------
Matrix provides official Debian packages via apt from https://matrix.org/packages/debian/.
Note that these packages do not include a client - choose one from
https://matrix.org/docs/projects/try-matrix-now.html (or build your own with one of our SDKs :)
Fedora
------
Synapse is in the Fedora repositories as ``matrix-synapse``::
sudo dnf install matrix-synapse
Oleg Girko provides Fedora RPMs at
https://obs.infoserver.lv/project/monitor/matrix-synapse
OpenSUSE
--------
Synapse is in the OpenSUSE repositories as ``matrix-synapse``::
sudo zypper install matrix-synapse
SUSE Linux Enterprise Server
----------------------------
Unofficial package are built for SLES 15 in the openSUSE:Backports:SLE-15 repository at
https://download.opensuse.org/repositories/openSUSE:/Backports:/SLE-15/standard/
ArchLinux
---------
The quickest way to get up and running with ArchLinux is probably with the community package
https://www.archlinux.org/packages/community/any/matrix-synapse/, which should pull in most of
the necessary dependencies. If the default web client is to be served (enabled by default in
the generated config),
https://www.archlinux.org/packages/community/any/python2-matrix-angular-sdk/ will also need to
be installed.
Alternatively, to install using pip a few changes may be needed as ArchLinux
defaults to python 3, but synapse currently assumes python 2.7 by default:
pip may be outdated (6.0.7-1 and needs to be upgraded to 6.0.8-1 )::
sudo pip2.7 install --upgrade pip
You also may need to explicitly specify python 2.7 again during the install
request::
pip2.7 install https://github.com/matrix-org/synapse/tarball/master
If you encounter an error with lib bcrypt causing an Wrong ELF Class:
ELFCLASS32 (x64 Systems), you may need to reinstall py-bcrypt to correctly
compile it under the right architecture. (This should not be needed if
installing under virtualenv)::
sudo pip2.7 uninstall py-bcrypt
sudo pip2.7 install py-bcrypt
During setup of Synapse you need to call python2.7 directly again::
cd ~/.synapse
python2.7 -m synapse.app.homeserver \
--server-name machine.my.domain.name \
--config-path homeserver.yaml \
--generate-config
...substituting your host and domain name as appropriate.
FreeBSD
-------
Synapse can be installed via FreeBSD Ports or Packages contributed by Brendan Molloy from:
- Ports: ``cd /usr/ports/net-im/py-matrix-synapse && make install clean``
- Packages: ``pkg install py27-matrix-synapse``
OpenBSD
-------
There is currently no port for OpenBSD. Additionally, OpenBSD's security
settings require a slightly more difficult installation process.
1) Create a new directory in ``/usr/local`` called ``_synapse``. Also, create a
new user called ``_synapse`` and set that directory as the new user's home.
This is required because, by default, OpenBSD only allows binaries which need
write and execute permissions on the same memory space to be run from
``/usr/local``.
2) ``su`` to the new ``_synapse`` user and change to their home directory.
3) Create a new virtualenv: ``virtualenv -p python2.7 ~/.synapse``
4) Source the virtualenv configuration located at
``/usr/local/_synapse/.synapse/bin/activate``. This is done in ``ksh`` by
using the ``.`` command, rather than ``bash``'s ``source``.
5) Optionally, use ``pip`` to install ``lxml``, which Synapse needs to parse
webpages for their titles.
6) Use ``pip`` to install this repository: ``pip install
https://github.com/matrix-org/synapse/tarball/master``
7) Optionally, change ``_synapse``'s shell to ``/bin/false`` to reduce the
chance of a compromised Synapse server being used to take over your box.
After this, you may proceed with the rest of the install directions.
NixOS
-----
Robin Lambertz has packaged Synapse for NixOS at:
https://github.com/NixOS/nixpkgs/blob/master/nixos/modules/services/misc/matrix-synapse.nix
Windows Install
---------------
Synapse can be installed on Cygwin. It requires the following Cygwin packages:
- gcc
- git
- libffi-devel
- openssl (and openssl-devel, python-openssl)
- python
- python-setuptools
The content repository requires additional packages and will be unable to process
uploads without them:
- libjpeg8
- libjpeg8-devel
- zlib
If you choose to install Synapse without these packages, you will need to reinstall
``pillow`` for changes to be applied, e.g. ``pip uninstall pillow`` ``pip install
pillow --user``
Troubleshooting:
- You may need to upgrade ``setuptools`` to get this to work correctly:
``pip install setuptools --upgrade``.
- You may encounter errors indicating that ``ffi.h`` is missing, even with
``libffi-devel`` installed. If you do, copy the ``.h`` files:
``cp /usr/lib/libffi-3.0.13/include/*.h /usr/include``
- You may need to install libsodium from source in order to install PyNacl. If
you do, you may need to create a symlink to ``libsodium.a`` so ``ld`` can find
it: ``ln -s /usr/local/lib/libsodium.a /usr/lib/libsodium.a``
Troubleshooting
===============
Troubleshooting Installation
----------------------------
Synapse requires pip 1.7 or later, so if your OS provides too old a version you
may need to manually upgrade it::
sudo pip install --upgrade pip
Installing may fail with ``Could not find any downloads that satisfy the requirement pymacaroons-pynacl (from matrix-synapse==0.12.0)``.
You can fix this by manually upgrading pip and virtualenv::
sudo pip install --upgrade virtualenv
You can next rerun ``virtualenv -p python2.7 synapse`` to update the virtual env.
Installing may fail during installing virtualenv with ``InsecurePlatformWarning: A true SSLContext object is not available. This prevents urllib3 from configuring SSL appropriately and may cause certain SSL connections to fail. For more information, see https://urllib3.readthedocs.org/en/latest/security.html#insecureplatformwarning.``
You can fix this by manually installing ndg-httpsclient::
pip install --upgrade ndg-httpsclient
Installing may fail with ``mock requires setuptools>=17.1. Aborting installation``.
You can fix this by upgrading setuptools::
pip install --upgrade setuptools
If pip crashes mid-installation for reason (e.g. lost terminal), pip may
refuse to run until you remove the temporary installation directory it
created. To reset the installation::
rm -rf /tmp/pip_install_matrix
pip seems to leak *lots* of memory during installation. For instance, a Linux
host with 512MB of RAM may run out of memory whilst installing Twisted. If this
happens, you will have to individually install the dependencies which are
failing, e.g.::
pip install twisted
On OS X, if you encounter clang: error: unknown argument: '-mno-fused-madd' you
will need to export CFLAGS=-Qunused-arguments.
Troubleshooting Running
-----------------------
If synapse fails with ``missing "sodium.h"`` crypto errors, you may need
to manually upgrade PyNaCL, as synapse uses NaCl (https://nacl.cr.yp.to/) for
encryption and digital signatures.
Unfortunately PyNACL currently has a few issues
(https://github.com/pyca/pynacl/issues/53) and
(https://github.com/pyca/pynacl/issues/79) that mean it may not install
correctly, causing all tests to fail with errors about missing "sodium.h". To
fix try re-installing from PyPI or directly from
(https://github.com/pyca/pynacl)::
# Install from PyPI
pip install --user --upgrade --force pynacl
# Install from github
pip install --user https://github.com/pyca/pynacl/tarball/master
Running out of File Handles
~~~~~~~~~~~~~~~~~~~~~~~~~~~
If synapse runs out of filehandles, it typically fails badly - live-locking
at 100% CPU, and/or failing to accept new TCP connections (blocking the
connecting client). Matrix currently can legitimately use a lot of file handles,
thanks to busy rooms like #matrix:matrix.org containing hundreds of participating
servers. The first time a server talks in a room it will try to connect
simultaneously to all participating servers, which could exhaust the available
file descriptors between DNS queries & HTTPS sockets, especially if DNS is slow
to respond. (We need to improve the routing algorithm used to be better than
full mesh, but as of June 2017 this hasn't happened yet).
If you hit this failure mode, we recommend increasing the maximum number of
open file handles to be at least 4096 (assuming a default of 1024 or 256).
This is typically done by editing ``/etc/security/limits.conf``
Separately, Synapse may leak file handles if inbound HTTP requests get stuck
during processing - e.g. blocked behind a lock or talking to a remote server etc.
This is best diagnosed by matching up the 'Received request' and 'Processed request'
log lines and looking for any 'Processed request' lines which take more than
a few seconds to execute. Please let us know at #matrix-dev:matrix.org if
you see this failure mode so we can help debug it, however.

Setting up Federation
=====================
Federation is the process by which users on different servers can participate
in the same room. For this to work, those other servers must be able to contact
yours to send messages.
As explained in `Configuring synapse`_, the ``server_name`` in your
``homeserver.yaml`` file determines the way that other servers will reach
yours. By default, they will treat it as a hostname and try to connect to
port 8448. This is easy to set up and will work with the default configuration,
provided you set the ``server_name`` to match your machine's public DNS
hostname.
For a more flexible configuration, you can set up a DNS SRV record. This allows
you to run your server on a machine that might not have the same name as your
domain name. For example, you might want to run your server at
``synapse.example.com``, but have your Matrix user-ids look like
``@user:example.com``. (A SRV record also allows you to change the port from
the default 8448. However, if you are thinking of using a reverse-proxy on the
federation port, which is not recommended, be sure to read
`Reverse-proxying the federation port`_ first.)
To use a SRV record, first create your SRV record and publish it in DNS. This
should have the format ``_matrix._tcp.<yourdomain.com> <ttl> IN SRV 10 0 <port>
<synapse.server.name>``. The DNS record should then look something like::
$ dig -t srv _matrix._tcp.example.com
_matrix._tcp.example.com. 3600 IN SRV 10 0 8448 synapse.example.com.
Note that the server hostname cannot be an alias (CNAME record): it has to point
directly to the server hosting the synapse instance.
You can then configure your homeserver to use ``<yourdomain.com>`` as the domain in
its user-ids, by setting ``server_name``::
python -m synapse.app.homeserver \
--server-name <yourdomain.com> \
--config-path homeserver.yaml \
--generate-config
python -m synapse.app.homeserver --config-path homeserver.yaml
If you've already generated the config file, you need to edit the ``server_name``
in your ``homeserver.yaml`` file. If you've already started Synapse and a
database has been created, you will have to recreate the database.
If all goes well, you should be able to `connect to your server with a client`__,
and then join a room via federation. (Try ``#matrix-dev:matrix.org`` as a first
step. "Matrix HQ"'s sheer size and activity level tends to make even the
largest boxes pause for thought.)
.. __: `Connecting to Synapse from a client`_
Troubleshooting
---------------
You can use the federation tester to check if your homeserver is all set:
``https://matrix.org/federationtester/api/report?server_name=<your_server_name>``
If any of the attributes under "checks" is false, federation won't work.
The typical failure mode with federation is that when you try to join a room,
it is rejected with "401: Unauthorized". Generally this means that other
servers in the room couldn't access yours. (Joining a room over federation is a
complicated dance which requires connections in both directions).
So, things to check are:
* If you are trying to use a reverse-proxy, read `Reverse-proxying the
federation port`_.
* If you are not using a SRV record, check that your ``server_name`` (the part
of your user-id after the ``:``) matches your hostname, and that port 8448 on
that hostname is reachable from outside your network.
* If you *are* using a SRV record, check that it matches your ``server_name``
(it should be ``_matrix._tcp.<server_name>``), and that the port and hostname
it specifies are reachable from outside your network.

Synapse offers two database engines:
* `SQLite <https://sqlite.org/>`_
* `PostgreSQL <https://www.postgresql.org>`_
As of Synapse 0.9, `PostgreSQL <https://www.postgresql.org>`_ is supported as an
alternative to the `SQLite <https://sqlite.org/>`_ database that Synapse has
traditionally used for convenience and simplicity.
By default Synapse uses SQLite in and doing so trades performance for convenience.
SQLite is only recommended in Synapse for testing purposes or for servers with
light workloads.

Using a reverse proxy with Synapse
@@ -195,13 +716,102 @@ Using a reverse proxy with Synapse
It is recommended to put a reverse proxy such as
`nginx <https://nginx.org/en/docs/http/ngx_http_proxy_module.html>`_,
`Apache <https://httpd.apache.org/docs/current/mod/mod_proxy_http.html>`_,
`Caddy <https://caddyserver.com/docs/proxy>`_ or
`Apache <https://httpd.apache.org/docs/current/mod/mod_proxy_http.html>`_ or
`HAProxy <https://www.haproxy.org/>`_ in front of Synapse. One advantage of
doing so is that it means that you can expose the default https port (443) to
Matrix clients without needing to run Synapse with root privileges.
For information on configuring one, see `<docs/reverse_proxy.rst>`_.
The most important thing to know here is that Matrix clients and other Matrix
servers do not necessarily need to connect to your server via the same
port. Indeed, clients will use port 443 by default, whereas servers default to
port 8448. Where these are different, we refer to the 'client port' and the
'federation port'.
The next most important thing to know is that using a reverse-proxy on the
federation port has a number of pitfalls. It is possible, but be sure to read
`Reverse-proxying the federation port`_.
The recommended setup is therefore to configure your reverse-proxy on port 443
to port 8008 of synapse for client connections, but to also directly expose port
8448 for server-server connections. All the Matrix endpoints begin ``/_matrix``,
so an example nginx configuration might look like::
server {
listen 443 ssl;
listen [::]:443 ssl;
server_name matrix.example.com;
location /_matrix {
proxy_pass http://localhost:8008;
proxy_set_header X-Forwarded-For $remote_addr;
}
}
You will also want to set ``bind_addresses: ['127.0.0.1']`` and ``x_forwarded: true``
for port 8008 in ``homeserver.yaml`` to ensure that client IP addresses are
recorded correctly.
Having done so, you can then use ``https://matrix.example.com`` (instead of
``https://matrix.example.com:8448``) as the "Custom server" when `Connecting to
Synapse from a client`_.
Reverse-proxying the federation port
------------------------------------
There are two issues to consider before using a reverse-proxy on the federation
port:
* Due to the way SSL certificates are managed in the Matrix federation protocol
(see `spec`__), Synapse needs to be configured with the path to the SSL
certificate, *even if you do not terminate SSL at Synapse*.
.. __: `key_management`_
* Synapse does not currently support SNI on the federation protocol
(`bug #1491 <https://github.com/matrix-org/synapse/issues/1491>`_), which
means that using name-based virtual hosting is unreliable.
Furthermore, a number of the normal reasons for using a reverse-proxy do not
apply:
* Other servers will connect on port 8448 by default, so there is no need to
listen on port 443 (for federation, at least), which avoids the need for root
privileges and virtual hosting.
* A self-signed SSL certificate is fine for federation, so there is no need to
automate renewals. (The certificate generated by ``--generate-config`` is
valid for 10 years.)
If you want to set up a reverse-proxy on the federation port despite these
caveats, you will need to do the following:
* In ``homeserver.yaml``, set ``tls_certificate_path`` to the path to the SSL
certificate file used by your reverse-proxy, and set ``no_tls`` to ``True``.
(``tls_private_key_path`` will be ignored if ``no_tls`` is ``True``.)
* In your reverse-proxy configuration:
* If there are other virtual hosts on the same port, make sure that the
*default* one uses the certificate configured above.
* Forward ``/_matrix`` to Synapse.
* If your reverse-proxy is not listening on port 8448, publish a SRV record to
tell other servers how to find you. See `Setting up Federation`_.
When updating the SSL certificate, just update the file pointed to by
``tls_certificate_path``: there is no need to restart synapse. (You may like to
use a symbolic link to help make this process atomic.)
The most common mistake when setting up federation is not to tell Synapse about
your SSL certificate. To check it, you can visit
``https://matrix.org/federationtester/api/report?server_name=<your_server_name>``.
Unfortunately, there is no UI for this yet, but, you should see
``"MatchingTLSFingerprint": true``. If not, check that
``Certificates[0].SHA256Fingerprint`` (the fingerprint of the certificate
presented by your reverse-proxy) matches ``Keys.tls_fingerprints[0].sha256``

Help!! Synapse is slow and eats all my RAM/CPU!
-----------------------------------------------
First, ensure you are running the latest version of Synapse, using Python 3
with a PostgreSQL database.
Help!! Synapse eats all my RAM!
===============================
Synapse's architecture is quite RAM hungry currently - we deliberately
cache a lot of recent room data and metadata in RAM in order to speed up
common requests. We'll improve this in the future, but for now the easiest
common requests. We'll improve this in future, but for now the easiest
way to either reduce the RAM usage (at the risk of slowing things down)
is to set the almost-undocumented ``SYNAPSE_CACHE_FACTOR`` environment
variable. The default is 0.5, which can be decreased to reduce RAM usage
variable. The default is 0.5, which can be decreased to reduce RAM usage
in memory constrained enviroments, or increased if performance starts to
degrade.
However, degraded performance due to a low cache factor, common on
machines with slow disks, often leads to explosions in memory use due
backlogged requests. In this case, reducing the cache factor will make
things worse. Instead, try increasing it drastically. 2.0 is a good
starting value.
Using `libjemalloc <http://jemalloc.net/>`_ can also yield a significant
improvement in overall memory use, and especially in terms of giving back
RAM to the OS. To use it, the library must simply be put in the
LD_PRELOAD environment variable when launching Synapse. On Debian, this
can be done by installing the ``libjemalloc1`` package and adding this
line to ``/etc/default/matrix-synapse``::
LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libjemalloc.so.1
This can make a significant difference on Python 2.7 - it's unclear how
much of an improvement it provides on Python 3.x.
If you're encountering high CPU use by the Synapse process itself, you
may be affected by a bug with presence tracking that leads to a
massive excess of outgoing federation requests (see `discussion
<https://github.com/matrix-org/synapse/issues/3971>`_). If metrics
indicate that your server is also issuing far more outgoing federation
requests than can be accounted for by your users' activity, this is a
likely cause. The misbehavior can be worked around by setting

Upgrading to v1.2.0
===================
Some counter metrics have been renamed, with the old names deprecated. See
`the metrics documentation <docs/metrics-howto.rst#renaming-of-metrics--deprecation-of-old-names-in-12>`_
for details.
Upgrading to v1.1.0
===================
Synapse v1.1.0 removes support for older Python and PostgreSQL versions, as
outlined in `our deprecation notice <https://matrix.org/blog/2019/04/08/synapse-deprecating-postgres-9-4-and-python-2-x>`_.
Minimum Python Version
----------------------
Synapse v1.1.0 has a minimum Python requirement of Python 3.5. Python 3.6 or
Python 3.7 are recommended as they have improved internal string handling,
significantly reducing memory usage.
If you use current versions of the Matrix.org-distributed Debian packages or
Docker images, action is not required.
If you install Synapse in a Python virtual environment, please see "Upgrading to
v0.34.0" for notes on setting up a new virtualenv under Python 3.
Minimum PostgreSQL Version
--------------------------
If using PostgreSQL under Synapse, you will need to use PostgreSQL 9.5 or above.
Please see the
`PostgreSQL documentation <https://www.postgresql.org/docs/11/upgrading.html>`_
for more details on upgrading your database.
Upgrading to v1.0
=================
Validation of TLS certificates
------------------------------
Synapse v1.0 is the first release to enforce
validation of TLS certificates for the federation API. It is therefore
essential that your certificates are correctly configured. See the `FAQ
<docs/MSC1711_certificates_FAQ.md>`_ for more information.
Note, v1.0 installations will also no longer be able to federate with servers
that have not correctly configured their certificates.
In rare cases, it may be desirable to disable certificate checking: for
example, it might be essential to be able to federate with a given legacy
server in a closed federation. This can be done in one of two ways:-
* Configure the global switch ``federation_verify_certificates`` to ``false``.
* Configure a whitelist of server domains to trust via ``federation_certificate_verification_whitelist``.
See the `sample configuration file <docs/sample_config.yaml>`_
for more details on these settings.
Email
-----
When a user requests a password reset, Synapse will send an email to the
user to confirm the request.
Previous versions of Synapse delegated the job of sending this email to an
identity server. If the identity server was somehow malicious or became
compromised, it would be theoretically possible to hijack an account through
this means.
Therefore, by default, Synapse v1.0 will send the confirmation email itself. If
Synapse is not configured with an SMTP server, password reset via email will be
disabled.
To configure an SMTP server for Synapse, modify the configuration section
headed ``email``, and be sure to have at least the ``smtp_host``, ``smtp_port``
and ``notif_from`` fields filled out. You may also need to set ``smtp_user``,
``smtp_pass``, and ``require_transport_security``.
If you are absolutely certain that you wish to continue using an identity
server for password resets, set ``trust_identity_server_for_password_resets`` to ``true``.
See the `sample configuration file <docs/sample_config.yaml>`_
for more details on these settings.
Upgrading to v0.99.0
====================
Please be aware that, before Synapse v1.0 is released around March 2019, you
will need to replace any self-signed certificates with those verified by a
root CA. Information on how to do so can be found at `the ACME docs
<docs/ACME.md>`_.
For more information on configuring TLS certificates see the `FAQ <docs/MSC1711_certificates_FAQ.md>`_.
Upgrading to v0.34.0
====================
1. This release is the first to fully support Python 3. Synapse will now run on
Python versions 3.5, or 3.6 (as well as 2.7). We recommend switching to
Python 3, as it has been shown to give performance improvements.
For users who have installed Synapse into a virtualenv, we recommend doing
this by creating a new virtualenv. For example::
virtualenv -p python3 ~/synapse/env3
source ~/synapse/env3/bin/activate
pip install matrix-synapse
You can then start synapse as normal, having activated the new virtualenv::
cd ~/synapse
source env3/bin/activate
synctl start
Users who have installed from distribution packages should see the relevant
package documentation. See below for notes on Debian packages.
* When upgrading to Python 3, you **must** make sure that your log files are
configured as UTF-8, by adding ``encoding: utf8`` to the
``RotatingFileHandler`` configuration (if you have one) in your
``<server>.log.config`` file. For example, if your ``log.config`` file
contains::
handlers:
file:
class: logging.handlers.RotatingFileHandler
formatter: precise
filename: homeserver.log
maxBytes: 104857600
backupCount: 10
filters: [context]
console:
class: logging.StreamHandler
formatter: precise
filters: [context]
Then you should update this to be::
handlers:
file:
class: logging.handlers.RotatingFileHandler
formatter: precise
filename: homeserver.log
maxBytes: 104857600
backupCount: 10
filters: [context]
encoding: utf8
console:
class: logging.StreamHandler
formatter: precise
filters: [context]
There is no need to revert this change if downgrading to Python 2.
We are also making available Debian packages which will run Synapse on
Python 3. You can switch to these packages with ``apt-get install
matrix-synapse-py3``, however, please read `debian/NEWS
<https://github.com/matrix-org/synapse/blob/release-v0.34.0/debian/NEWS>`_
before doing so. The existing ``matrix-synapse`` packages will continue to
use Python 2 for the time being.
2. This release removes the ``riot.im`` from the default list of trusted
identity servers.
If ``riot.im`` is in your homeserver's list of
``trusted_third_party_id_servers``, you should remove it. It was added in
case a hypothetical future identity server was put there. If you don't
remove it, users may be unable to deactivate their accounts.
3. This release no longer installs the (unmaintained) Matrix Console web client
as part of the default installation. It is possible to re-enable it by
installing it separately and setting the ``web_client_location`` config
option, but please consider switching to another client.
Upgrading to v0.33.7
====================
This release removes the example email notification templates from
``res/templates`` (they are now internal to the python package). This should
only affect you if you (a) deploy your Synapse instance from a git checkout or
a github snapshot URL, and (b) have email notifications enabled.
If you have email notifications enabled, you should ensure that
``email.template_dir`` is either configured to point at a directory where you
have installed customised templates, or leave it unset to use the default
templates.
Upgrading to v0.27.3
Upgrading to $NEXT_VERSION
====================
This release expands the anonymous usage stats sent if the opt-in
``report_stats`` configuration is set to ``true``. We now capture RSS memory
``report_stats`` configuration is set to ``true``. We now capture RSS memory
and cpu use at a very coarse level. This requires administrators to install
the optional ``psutil`` python module.
