<p><strong>DO NOT USE THESE DEMO SERVERS IN PRODUCTION</strong></p>
<p>Requires you to have a <a href="https://matrix-org.github.io/synapse/develop/development/contributing_guide.html#4-install-the-dependencies">Synapse development environment setup</a>.</p>
<p>The demo setup allows running three federation Synapse servers, with server
names <code>localhost:8480</code>, <code>localhost:8481</code>, and <code>localhost:8482</code>.</p>
<p>You can access them via any Matrix client over HTTP at <code>localhost:8080</code>,
<code>localhost:8081</code>, and <code>localhost:8082</code> or over HTTPS at <code>localhost:8480</code>,
<code>localhost:8481</code>, and <code>localhost:8482</code>.</p>
<p>To enable the servers to communicate, self-signed SSL certificates are generated
and the servers are configured in a highly insecure way, including:</p>
<ul>
<li>Not checking certificates over federation.</li>
<li>Not verifying keys.</li>
</ul>
<p>The servers are configured to store their data under <code>demo/8080</code>, <code>demo/8081</code>, and
<code>demo/8082</code>. This includes configuration, logs, SQLite databases, and media.</p>
<p>Note that when joining a public room on a different homeserver via &quot;#foo:bar.net&quot;,
then you are (in the current implementation) joining a room with room_id &quot;foo&quot;.
This means that it won't work if your homeserver already has a room with that
name.</p>
<h2 id="using-the-demo-scripts"><a class="header" href="#using-the-demo-scripts">Using the demo scripts</a></h2>
<p>There's three main scripts with straightforward purposes:</p>
<ul>
<li><code>start.sh</code> will start the Synapse servers, generating any missing configuration.
<ul>
<li>This accepts a single parameter <code>--no-rate-limit</code> to &quot;disable&quot; rate limits
(they actually still exist, but are very high).</li>
</ul>
</li>
<li><code>stop.sh</code> will stop the Synapse servers.</li>
<li><code>clean.sh</code> will delete the configuration, databases, log files, etc.</li>
</ul>
<p>To start a completely new set of servers, run:</p>
<pre><code class="language-sh">./demo/stop.sh; ./demo/clean.sh &amp;&amp; ./demo/start.sh
</code></pre>
