### Using synctl with workers
|
|
|
|
If you want to use `synctl` to manage your synapse processes, you will need to
|
|
create an an additional configuration file for the main synapse process. That
|
|
configuration should look like this:
|
|
|
|
```yaml
|
|
worker_app: synapse.app.homeserver
|
|
```
|
|
|
|
Additionally, each worker app must be configured with the name of a "pid file",
|
|
to which it will write its process ID when it starts. For example, for a
|
|
synchrotron, you might write:
|
|
|
|
```yaml
|
|
worker_pid_file: /home/matrix/synapse/worker1.pid
|
|
```
|
|
|
|
Finally, to actually run your worker-based synapse, you must pass synctl the `-a`
|
|
commandline option to tell it to operate on all the worker configurations found
|
|
in the given directory, e.g.:
|
|
|
|
```sh
|
|
synctl -a $CONFIG/workers start
|
|
```
|
|
|
|
Currently one should always restart all workers when restarting or upgrading
|
|
synapse, unless you explicitly know it's safe not to. For instance, restarting
|
|
synapse without restarting all the synchrotrons may result in broken typing
|
|
notifications.
|
|
|
|
To manipulate a specific worker, you pass the -w option to synctl:
|
|
|
|
```sh
|
|
synctl -w $CONFIG/workers/worker1.yaml restart
|
|
```
