## 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](../federate.md).
|
|
|
|
## Installing Synapse
|
|
|
|
### Installing from source
|
|
|
|
(Prebuilt packages are available for some platforms - see [Prebuilt packages](#prebuilt-packages).)
|
|
|
|
When installing from source please make sure that the [Platform-specific prerequisites](#platform-specific-prerequisites) are already installed.
|
|
|
|
System requirements:
|
|
|
|
- POSIX-compliant system (tested on Linux & OS X)
|
|
- Python 3.5.2 or later, up to Python 3.9.
|
|
- At least 1GB of free RAM if you want to join large public rooms like #matrix:matrix.org
|
|
|
|
|
|
To install the Synapse homeserver run:
|
|
|
|
```sh
|
|
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:
|
|
|
|
```sh
|
|
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):
|
|
|
|
```sh
|
|
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 homeserver to
|
|
identify itself to other homeserver, 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 homeserver's keys, you may find that other homeserver 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:
|
|
|
|
```sh
|
|
cd ~/synapse
|
|
source env/bin/activate
|
|
synctl start
|
|
```
|
|
|
|
#### Platform-specific prerequisites
|
|
|
|
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.
|
|
|
|
##### Debian/Ubuntu/Raspbian
|
|
|
|
Installing prerequisites on Ubuntu or Debian:
|
|
|
|
```sh
|
|
sudo apt install build-essential python3-dev libffi-dev \
|
|
python3-pip python3-setuptools sqlite3 \
|
|
libssl-dev virtualenv libjpeg-dev libxslt1-dev
|
|
```
|
|
|
|
##### ArchLinux
|
|
|
|
Installing prerequisites on ArchLinux:
|
|
|
|
```sh
|
|
sudo pacman -S base-devel python python-pip \
|
|
python-setuptools python-virtualenv sqlite3
|
|
```
|
|
|
|
##### CentOS/Fedora
|
|
|
|
Installing prerequisites on CentOS or Fedora Linux:
|
|
|
|
```sh
|
|
sudo dnf install libtiff-devel libjpeg-devel libzip-devel freetype-devel \
|
|
libwebp-devel libxml2-devel libxslt-devel libpq-devel \
|
|
python3-virtualenv libffi-devel openssl-devel python3-devel
|
|
sudo dnf groupinstall "Development Tools"
|
|
```
|
|
|
|
##### macOS
|
|
|
|
Installing prerequisites on macOS:
|
|
|
|
You may need to install the latest Xcode developer tools:
|
|
```sh
|
|
xcode-select --install
|
|
```
|
|
|
|
On ARM-based Macs you may need to explicitly install libjpeg which is a pillow dependency. You can use Homebrew (https://brew.sh):
|
|
```sh
|
|
brew install jpeg
|
|
```
|
|
|
|
On macOS Catalina (10.15) you may need to explicitly install OpenSSL
|
|
via brew and inform `pip` about it so that `psycopg2` builds:
|
|
|
|
```sh
|
|
brew install openssl@1.1
|
|
export LDFLAGS="-L/usr/local/opt/openssl/lib"
|
|
export CPPFLAGS="-I/usr/local/opt/openssl/include"
|
|
```
|
|
|
|
##### OpenSUSE
|
|
|
|
Installing prerequisites on openSUSE:
|
|
|
|
```sh
|
|
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
|
|
|
|
A port of Synapse is available under `net/synapse`. The filesystem
|
|
underlying the homeserver directory (defaults to `/var/synapse`) has to be
|
|
mounted with `wxallowed` (cf. `mount(8)`), so creating a separate filesystem
|
|
and mounting it to `/var/synapse` should be taken into consideration.
|
|
|
|
To be able to build Synapse's dependency on python the `WRKOBJDIR`
|
|
(cf. `bsd.port.mk(5)`) for building python, too, needs to be on a filesystem
|
|
mounted with `wxallowed` (cf. `mount(8)`).
|
|
|
|
Creating a `WRKOBJDIR` for building python under `/usr/local` (which on a
|
|
default OpenBSD installation is mounted with `wxallowed`):
|
|
|
|
```sh
|
|
doas mkdir /usr/local/pobj_wxallowed
|
|
```
|
|
|
|
Assuming `PORTS_PRIVSEP=Yes` (cf. `bsd.port.mk(5)`) and `SUDO=doas` are
|
|
configured in `/etc/mk.conf`:
|
|
|
|
```sh
|
|
doas chown _pbuild:_pbuild /usr/local/pobj_wxallowed
|
|
```
|
|
|
|
Setting the `WRKOBJDIR` for building python:
|
|
|
|
```sh
|
|
echo WRKOBJDIR_lang/python/3.7=/usr/local/pobj_wxallowed \\nWRKOBJDIR_lang/python/2.7=/usr/local/pobj_wxallowed >> /etc/mk.conf
|
|
```
|
|
|
|
Building Synapse:
|
|
|
|
```sh
|
|
cd /usr/ports/net/synapse
|
|
make install
|
|
```
|
|
|
|
##### 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.
|
|
|
|
### 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 official synapse image available at
|
|
<https://hub.docker.com/r/matrixdotorg/synapse> which can be used with
|
|
the docker-compose file available at
|
|
[contrib/docker](https://github.com/matrix-org/synapse/tree/develop/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, Element, coturn,
|
|
ma1sd, 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 Synapse via
|
|
<https://packages.matrix.org/debian/>. To install the latest release:
|
|
|
|
```sh
|
|
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
|
|
```
|
|
|
|
Packages are also published for release candidates. To enable the prerelease
|
|
channel, add `prerelease` to the `sources.list` line. For example:
|
|
|
|
```sh
|
|
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 prerelease" |
|
|
sudo tee /etc/apt/sources.list.d/matrix-org.list
|
|
sudo apt update
|
|
sudo apt install matrix-synapse-py3
|
|
```
|
|
|
|
The fingerprint of the repository signing key (as shown by `gpg
|
|
/usr/share/keyrings/matrix-org-archive-keyring.gpg`) is
|
|
`AAF9AE843A7584B5A3E4CD2BCF45A512DE2DA058`.
|
|
|
|
##### Downstream Debian packages
|
|
|
|
We do not recommend using the packages from the default Debian `buster`
|
|
repository at this time, as they are old and suffer from known security
|
|
vulnerabilities. You can install the latest version of Synapse from
|
|
[our repository](#matrixorg-packages) or from `buster-backports`. Please
|
|
see the [Debian documentation](https://backports.debian.org/Instructions/)
|
|
for information on how to use backports.
|
|
|
|
If you are using Debian `sid` or testing, Synapse is available in the default
|
|
repositories and it should be possible to install it simply with:
|
|
|
|
```sh
|
|
sudo apt install matrix-synapse
|
|
```
|
|
|
|
##### Downstream Ubuntu packages
|
|
|
|
We do not recommend using the packages in the default Ubuntu repository
|
|
at this time, as they are old and suffer from known security vulnerabilities.
|
|
The latest version of Synapse can be installed from [our repository](#matrixorg-packages).
|
|
|
|
#### Fedora
|
|
|
|
Synapse is in the Fedora repositories as `matrix-synapse`:
|
|
|
|
```sh
|
|
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`:
|
|
|
|
```sh
|
|
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 ):
|
|
|
|
```sh
|
|
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):
|
|
|
|
```sh
|
|
sudo pip uninstall py-bcrypt
|
|
sudo pip install py-bcrypt
|
|
```
|
|
|
|
#### Void Linux
|
|
|
|
Synapse can be found in the void repositories as 'synapse':
|
|
|
|
```sh
|
|
xbps-install -Su
|
|
xbps-install -S synapse
|
|
```
|
|
|
|
#### 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 py37-matrix-synapse`
|
|
|
|
#### OpenBSD
|
|
|
|
As of OpenBSD 6.7 Synapse is available as a pre-compiled binary. The filesystem
|
|
underlying the homeserver directory (defaults to `/var/synapse`) has to be
|
|
mounted with `wxallowed` (cf. `mount(8)`), so creating a separate filesystem
|
|
and mounting it to `/var/synapse` should be taken into consideration.
|
|
|
|
Installing Synapse:
|
|
|
|
```sh
|
|
doas pkg_add 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.
|
|
|
|
### Using PostgreSQL
|
|
|
|
By default Synapse uses an [SQLite](https://sqlite.org/) database and in doing so trades
|
|
performance for convenience. Almost all installations should opt to use [PostgreSQL](https://www.postgresql.org)
|
|
instead. Advantages include:
|
|
|
|
- significant performance improvements due to the superior threading and
|
|
caching model, smarter query optimiser
|
|
- allowing the DB to be run on separate hardware
|
|
|
|
For information on how to install and use PostgreSQL in Synapse, please see
|
|
[Using Postgres](../postgres.md)
|
|
|
|
SQLite is only acceptable for testing purposes. SQLite should not be used in
|
|
a production server. Synapse will perform poorly when using
|
|
SQLite, especially when participating in large rooms.
|
|
|
|
### TLS certificates
|
|
|
|
The default configuration exposes a single HTTP port on the local
|
|
interface: `http://localhost:8008`. It is suitable for local testing,
|
|
but for any practical use, you will need Synapse's APIs to be served
|
|
over HTTPS.
|
|
|
|
The recommended way to do so is to set up a reverse proxy on port
|
|
`8448`. You can find documentation on doing so in
|
|
[the reverse proxy documentation](../reverse_proxy.md).
|
|
|
|
Alternatively, you can configure Synapse to expose an HTTPS port. To do
|
|
so, 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:
|
|
|
|
```yaml
|
|
- 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 will need to manage
|
|
provisioning of these certificates yourself.
|
|
|
|
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
|
|
[Federation](../federate.md).
|
|
|
|
### Client Well-Known URI
|
|
|
|
Setting up the client Well-Known URI is optional but if you set it up, it will
|
|
allow users to enter their full username (e.g. `@user:<server_name>`) into clients
|
|
which support well-known lookup to automatically configure the homeserver and
|
|
identity server URLs. This is useful so that users don't have to memorize or think
|
|
about the actual homeserver URL you are using.
|
|
|
|
The URL `https://<server_name>/.well-known/matrix/client` should return JSON in
|
|
the following format.
|
|
|
|
```json
|
|
{
|
|
"m.homeserver": {
|
|
"base_url": "https://<matrix.example.com>"
|
|
}
|
|
}
|
|
```
|
|
|
|
It can optionally contain identity server information as well.
|
|
|
|
```json
|
|
{
|
|
"m.homeserver": {
|
|
"base_url": "https://<matrix.example.com>"
|
|
},
|
|
"m.identity_server": {
|
|
"base_url": "https://<identity.example.com>"
|
|
}
|
|
}
|
|
```
|
|
|
|
To work in browser based clients, the file must be served with the appropriate
|
|
Cross-Origin Resource Sharing (CORS) headers. A recommended value would be
|
|
`Access-Control-Allow-Origin: *` which would allow all browser based clients to
|
|
view it.
|
|
|
|
In nginx this would be something like:
|
|
|
|
```nginx
|
|
location /.well-known/matrix/client {
|
|
return 200 '{"m.homeserver": {"base_url": "https://<matrix.example.com>"}}';
|
|
default_type application/json;
|
|
add_header Access-Control-Allow-Origin *;
|
|
}
|
|
```
|
|
|
|
You should also ensure the `public_baseurl` option in `homeserver.yaml` is set
|
|
correctly. `public_baseurl` should be set to the URL that clients will use to
|
|
connect to your server. This is the same URL you put for the `m.homeserver`
|
|
`base_url` above.
|
|
|
|
```yaml
|

### Email
|
|
|
|
It is desirable for Synapse to have the capability to send email. This allows
|
|
Synapse to send password reset emails, send verifications when an email address
|
|
is added to a user's account, and send email notifications to users when they
|
|
receive new messages.
|
|
|
|
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 email is not configured, password reset, registration and notifications via
|
|
email will be disabled.
|
|
|
|
### Registering a user
|
|
|
|
The easiest way to create a new user is to do so from a client like [Element](https://element.io/).
|
|
|
|
Alternatively, you can do so from the command line. This can be done as follows:
|
|
|
|
1. If synapse was installed via pip, activate the virtualenv as follows (if Synapse was
|
|
installed via a prebuilt package, `register_new_matrix_user` should already be
|
|
on the search path):
|
|
```sh
|
|
cd ~/synapse
|
|
source env/bin/activate
|
|
synctl start # if not already running
|
|
```
|
|
2. Run the following command:
|
|
```sh
|
|
register_new_matrix_user -c homeserver.yaml http://localhost:8008
|
|
```
|
|
|
|
This will prompt you to add details for the new user, and will then connect to
|
|
the running Synapse to create the new user. For example:
|
|
```
|
|
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 [TURN setup](../turn-howto.md) 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` python dependency 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.
|
|
|
|
### Troubleshooting Installation
|
|
|
|
`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.:
|
|
|
|
```sh
|
|
pip install twisted
|
|
```
|
