<h2 id="choosing-your-server-name"><a class="header" href="#choosing-your-server-name">Choosing your server name</a></h2>
 | 
						|
<p>It is important to choose the name for your server before you install Synapse,
 | 
						|
because it cannot be changed later.</p>
 | 
						|
<p>The server name determines the "domain" part of user-ids for users on your
 | 
						|
server: these will all be of the format <code>@user:my.domain.name</code>. It also
 | 
						|
determines how other matrix servers will reach yours for federation.</p>
 | 
						|
<p>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
 | 
						|
(<code>example.com</code>) rather than a matrix-specific hostname here (in the same way
 | 
						|
that your email address is probably <code>user@example.com</code> rather than
 | 
						|
<code>user@email.example.com</code>) - but doing so may require more advanced setup: see
 | 
						|
<a href="../federate.html">Setting up Federation</a>.</p>

<p>It's also possible to install Synapse as a Python module from PyPI.</p>
 | 
						|
<p>When following this route please make sure that the <a href="#platform-specific-prerequisites">Platform-specific prerequisites</a> are already installed.</p>
 | 
						|
<p>System requirements:</p>
 | 
						|
<ul>
 | 
						|
<li>POSIX-compliant system (tested on Linux & OS X)</li>
 | 
						|
<li>Python 3.7 or later, up to Python 3.9.</li>
 | 
						|
<li>At least 1GB of free RAM if you want to join large public rooms like #matrix:matrix.org</li>
 | 
						|
</ul>
 | 
						|
<p>To install the Synapse homeserver run:</p>
 | 
						|
<pre><code class="language-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
 | 
						|
</code></pre>
 | 
						|
<p>This will download Synapse from <a href="https://pypi.org/project/matrix-synapse">PyPI</a>
 | 
						|
and install it, along with the python libraries it uses, into a virtual environment
 | 
						|
under <code>~/synapse/env</code>.  Feel free to pick a different directory if you
 | 
						|
prefer.</p>
 | 
						|
<p>This Synapse installation can then be later upgraded by using pip again with the
 | 
						|
update flag:</p>
 | 
						|
<pre><code class="language-sh">source ~/synapse/env/bin/activate
 | 
						|
pip install -U matrix-synapse
 | 
						|
</code></pre>
 | 
						|
<p>Before you can start Synapse, you will need to generate a configuration
 | 
						|
file. To do this, run (in your virtualenv, as before):</p>
 | 
						|
<pre><code class="language-sh">cd ~/synapse
 | 
						|
python -m synapse.app.homeserver \
 | 
						|
    --server-name my.domain.name \
 | 
						|
    --config-path homeserver.yaml \
 | 
						|
    --generate-config \
 | 
						|
    --report-stats=[yes|no]
 | 
						|
</code></pre>
 | 
						|
<p>... substituting an appropriate value for <code>--server-name</code>.</p>
 | 
						|
<p>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 <code><server name>.signing.key</code> file (the second word) to something
 | 
						|
different. See the <a href="https://matrix.org/docs/spec/server_server/latest.html#retrieving-server-keys">spec</a> for more information on key management).</p>
 | 
						|
<p>To actually run your new homeserver, pick a working directory for Synapse to
 | 
						|
run (e.g. <code>~/synapse</code>), and:</p>
 | 
						|
<pre><code class="language-sh">cd ~/synapse
 | 
						|
source env/bin/activate
 | 
						|
synctl start
 | 
						|

<p>Synapse is written in Python but some of the libraries it uses are written in

<p>For information on how to install and use PostgreSQL in Synapse, please see
 | 
						|
<a href="../postgres.html">Using Postgres</a></p>
 | 
						|
<p>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.</p>
 | 
						|
<h3 id="tls-certificates"><a class="header" href="#tls-certificates">TLS certificates</a></h3>
 | 
						|
<p>The default configuration exposes a single HTTP port on the local
 | 
						|
interface: <code>http://localhost:8008</code>. It is suitable for local testing,
 | 
						|
but for any practical use, you will need Synapse's APIs to be served
 | 
						|
over HTTPS.</p>
 | 
						|
<p>The recommended way to do so is to set up a reverse proxy on port
 | 
						|
<code>8448</code>. You can find documentation on doing so in
 | 
						|
<a href="../reverse_proxy.html">the reverse proxy documentation</a>.</p>
 | 
						|
<p>Alternatively, you can configure Synapse to expose an HTTPS port. To do
 | 
						|
so, you will need to edit <code>homeserver.yaml</code>, as follows:</p>
 | 
						|
<ul>
 | 
						|
<li>First, under the <code>listeners</code> section, uncomment the configuration for the
 | 
						|
TLS-enabled listener. (Remove the hash sign (<code>#</code>) at the start of
 | 
						|
each line). The relevant lines are like this:</li>
 | 
						|
</ul>
 | 
						|
<pre><code class="language-yaml">  - port: 8448
 | 
						|
    type: http
 | 
						|
    tls: true
 | 
						|
    resources:
 | 
						|
      - names: [client, federation]
 | 
						|
</code></pre>
 | 
						|
<ul>
 | 
						|
<li>
 | 
						|
<p>You will also need to uncomment the <code>tls_certificate_path</code> and
 | 
						|
<code>tls_private_key_path</code> lines under the <code>TLS</code> section. You will need to manage
 | 
						|
provisioning of these certificates yourself.</p>
 | 
						|
<p>If you are using your own certificate, be sure to use a <code>.pem</code> file that
 | 
						|
includes the full certificate chain including any intermediate certificates
 | 
						|
(for instance, if using certbot, use <code>fullchain.pem</code> as your certificate, not
 | 
						|
<code>cert.pem</code>).</p>
 | 
						|
</li>
 | 
						|
</ul>
 | 
						|
<p>For a more detailed guide to configuring your server for federation, see
 | 
						|
<a href="../federate.html">Federation</a>.</p>
 | 
						|
<h3 id="client-well-known-uri"><a class="header" href="#client-well-known-uri">Client Well-Known URI</a></h3>
 | 
						|
<p>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. <code>@user:<server_name></code>) 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.</p>
 | 
						|
<p>The URL <code>https://<server_name>/.well-known/matrix/client</code> should return JSON in
 | 
						|
the following format.</p>
 | 
						|
<pre><code class="language-json">{
 | 
						|
  "m.homeserver": {
 | 
						|
    "base_url": "https://<matrix.example.com>"
 | 
						|
  }
 | 
						|
}
 | 
						|
</code></pre>
 | 
						|
<p>It can optionally contain identity server information as well.</p>
 | 
						|
<pre><code class="language-json">{
 | 
						|
  "m.homeserver": {
 | 
						|
    "base_url": "https://<matrix.example.com>"
 | 
						|
  },
 | 
						|
  "m.identity_server": {
 | 
						|
    "base_url": "https://<identity.example.com>"
 | 
						|
  }
 | 
						|
}
 | 
						|
</code></pre>
 | 
						|
<p>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
 | 
						|
<code>Access-Control-Allow-Origin: *</code> which would allow all browser based clients to
 | 
						|
view it.</p>
 | 
						|
<p>In nginx this would be something like:</p>
 | 
						|
<pre><code class="language-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 *;
 | 
						|
}
 | 
						|
</code></pre>
 | 
						|
<p>You should also ensure the <code>public_baseurl</code> option in <code>homeserver.yaml</code> is set
 | 
						|
correctly. <code>public_baseurl</code> should be set to the URL that clients will use to
 | 
						|
connect to your server. This is the same URL you put for the <code>m.homeserver</code>
 | 
						|
<code>base_url</code> above.</p>
 | 
						|
<pre><code class="language-yaml">public_baseurl: "https://<matrix.example.com>"
 | 
						|
</code></pre>
 | 
						|
<h3 id="email"><a class="header" href="#email">Email</a></h3>
 | 
						|
<p>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.</p>
 | 
						|
<p>To configure an SMTP server for Synapse, modify the configuration section
 | 
						|
headed <code>email</code>, and be sure to have at least the <code>smtp_host</code>, <code>smtp_port</code>
 | 
						|
and <code>notif_from</code> fields filled out.  You may also need to set <code>smtp_user</code>,
 | 
						|
<code>smtp_pass</code>, and <code>require_transport_security</code>.</p>
 | 
						|
<p>If email is not configured, password reset, registration and notifications via
 | 
						|
email will be disabled.</p>
 | 
						|
<h3 id="registering-a-user"><a class="header" href="#registering-a-user">Registering a user</a></h3>
 | 
						|
<p>The easiest way to create a new user is to do so from a client like <a href="https://element.io/">Element</a>.</p>
 | 
						|
<p>Alternatively, you can do so from the command line. This can be done as follows:</p>
 | 
						|
<ol>
 | 
						|
<li>If synapse was installed via pip, activate the virtualenv as follows (if Synapse was
 | 
						|
installed via a prebuilt package, <code>register_new_matrix_user</code> should already be
 | 
						|
on the search path):
 | 
						|
<pre><code class="language-sh">cd ~/synapse
 | 
						|
source env/bin/activate
 | 
						|
synctl start # if not already running
 | 
						|
</code></pre>
 | 
						|
</li>
 | 
						|
<li>Run the following command:
 | 
						|
<pre><code class="language-sh">register_new_matrix_user -c homeserver.yaml http://localhost:8008
 | 
						|
</code></pre>
 | 
						|
</li>
 | 
						|
</ol>
 | 
						|
<p>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:</p>
 | 
						|
<pre><code>New user localpart: erikj
 | 
						|
Password:
 | 
						|
Confirm password:
 | 
						|
Make admin [no]:
 | 
						|
Success!
 | 
						|
</code></pre>
 | 
						|
<p>This process uses a setting <code>registration_shared_secret</code> in
 | 
						|
<code>homeserver.yaml</code>, which is shared between Synapse itself and the
 | 
						|
<code>register_new_matrix_user</code> script. It doesn't matter what it is (a random
 | 
						|
value is generated by <code>--generate-config</code>), but it should be kept secret, as
 | 
						|
anyone with knowledge of it can register users, including admin accounts,
 | 
						|
on your server even if <code>enable_registration</code> is <code>false</code>.</p>
 | 
						|
<h3 id="setting-up-a-turn-server"><a class="header" href="#setting-up-a-turn-server">Setting up a TURN server</a></h3>
 | 
						|
<p>For reliable VoIP calls to be routed via this homeserver, you MUST configure
 | 
						|
a TURN server. See <a href="../turn-howto.html">TURN setup</a> for details.</p>
 | 
						|
<h3 id="url-previews"><a class="header" href="#url-previews">URL previews</a></h3>
 | 
						|
<p>Synapse includes support for previewing URLs, which is disabled by default.  To
 | 
						|
turn it on you must enable the <code>url_preview_enabled: True</code> config parameter
 | 
						|
and explicitly specify the IP ranges that Synapse is not allowed to spider for
 | 
						|
previewing in the <code>url_preview_ip_range_blacklist</code> 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.</p>
 | 
						|
<p>This also requires the optional <code>lxml</code> python dependency to be  installed. This
 | 
						|
in turn requires the <code>libxml2</code> library to be available - on  Debian/Ubuntu this
 | 
						|
means <code>apt-get install libxml2-dev</code>, or equivalent for your OS.</p>
 | 
						|
<h3 id="troubleshooting-installation"><a class="header" href="#troubleshooting-installation">Troubleshooting Installation</a></h3>
 | 
						|
<p><code>pip</code> seems to leak <em>lots</em> 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.:</p>
 | 
						|
<pre><code class="language-sh">pip install twisted
 | 
						|
</code></pre>
