  150. <p>If you want to use <code>synctl</code> to manage your synapse processes, you will need to
  151. create an an additional configuration file for the main synapse process. That
  152. configuration should look like this:</p>
  153. <pre><code class="language-yaml">worker_app: synapse.app.homeserver
  154. </code></pre>
  155. <p>Additionally, each worker app must be configured with the name of a &quot;pid file&quot;,
  156. to which it will write its process ID when it starts. For example, for a
  157. synchrotron, you might write:</p>
  158. <pre><code class="language-yaml">worker_pid_file: /home/matrix/synapse/worker1.pid
  159. </code></pre>
  160. <p>Finally, to actually run your worker-based synapse, you must pass synctl the <code>-a</code>
  161. commandline option to tell it to operate on all the worker configurations found
  162. in the given directory, e.g.:</p>
  163. <pre><code class="language-sh">synctl -a $CONFIG/workers start
  164. </code></pre>
  165. <p>Currently one should always restart all workers when restarting or upgrading
  166. synapse, unless you explicitly know it's safe not to. For instance, restarting
  167. synapse without restarting all the synchrotrons may result in broken typing
  168. notifications.</p>
  169. <p>To manipulate a specific worker, you pass the -w option to synctl:</p>
  170. <pre><code class="language-sh">synctl -w $CONFIG/workers/worker1.yaml restart
  171. </code></pre>
