# Setup Synapse with Workers and Systemd
|
||
|
|
||
|
This is a setup for managing synapse with systemd including support for
|
||
|
managing workers. It provides a `matrix-synapse`, as well as a
|
||
|
`matrix-synapse-worker@` service for any workers you require. Additionally to
|
||
|
group the required services it sets up a `matrix.target`. You can use this to
|
||
|
automatically start any bot- or bridge-services. More on this in
|
||
|
[Bots and Bridges](#bots-and-bridges).
|
||
|
|
||
|
See the folder [system](system) for any service and target files.
|
||
|
|
||
|
The folder [workers](workers) contains an example configuration for the
|
||
|
`federation_reader` worker. Pay special attention to the name of the
|
||
|
configuration file. In order to work with the `matrix-synapse-worker@.service`
|
||
|
service, it needs to have the exact same name as the worker app.
|
||
|
|
||
|
This setup expects neither the homeserver nor any workers to fork. Forking is
|
||
|
handled by systemd.
|
||
|
|
||
|
## Setup
|
||
|
|
||
|
1. Adjust your matrix configs. Make sure that the worker config files have the
|
||
|
exact same name as the worker app. Compare `matrix-synapse-worker@.service` for
|
||
|
why. You can find an example worker config in the [workers](workers) folder. See
|
||
|
below for relevant settings in the `homeserver.yaml`.
|
||
|
2. Copy the `*.service` and `*.target` files in [system](system) to
|
||
|
`/etc/systemd/system`.
|
||
|
3. `systemctl enable matrix-synapse.service` this adds the homeserver
|
||
|
app to the `matrix.target`
|
||
|
4. *Optional.* `systemctl enable
|
||
|
matrix-synapse-worker@federation_reader.service` this adds the federation_reader
|
||
|
app to the `matrix-synapse.service`
|
||
|
5. *Optional.* Repeat step 4 for any additional workers you require.
|
||
|
6. *Optional.* Add any bots or bridges by enabling them.
|
||
|
7. Start all matrix related services via `systemctl start matrix.target`
|
||
|
8. *Optional.* Enable autostart of all matrix related services on system boot
|
||
|
via `systemctl enable matrix.target`
|
||
|
|
||
|
## Usage
|
||
|
|
||
|
After you have setup you can use the following commands to manage your synapse
|
||
|
installation:
|
||
|
|
||
|
```
|
||
|
# Start matrix-synapse, all workers and any enabled bots or bridges.
|
||
|
systemctl start matrix.target
|
||
|
|
||
|
# Restart matrix-synapse and all workers (not necessarily restarting bots
|
||
|
# or bridges, see "Bots and Bridges")
|
||
|
systemctl restart matrix-synapse.service
|
||
|
|
||
|
# Stop matrix-synapse and all workers (not necessarily restarting bots
|
||
|
# or bridges, see "Bots and Bridges")
|
||
|
systemctl stop matrix-synapse.service
|
||
|
|
||
|
# Restart a specific worker (i. e. federation_reader), the homeserver is
|
||
|
# unaffected by this.
|
||
|
systemctl restart matrix-synapse-worker@federation_reader.service
|
||
|
|
||
|
# Add a new worker (assuming all configs are setup already)
|
||
|
systemctl enable matrix-synapse-worker@federation_writer.service
|
||
|
systemctl restart matrix-synapse.service
|
||
|
```
|
||
|
|
||
|
## The Configs
|
||
|
|
||
|
Make sure the `worker_app` is set in the `homeserver.yaml` and it does not fork.
|
||
|
|
||
|
```
|
||
|
worker_app: synapse.app.homeserver
|
||
|
daemonize: false
|
||
|
```
|
||
|
|
||
|
None of the workers should fork, as forking is handled by systemd. Hence make
|
||
|
sure this is present in all worker config files.
|
||
|
|
||
|
```
|
||
|
worker_daemonize: false
|
||
|
```
|
||
|
|
||
|
The config files of all workers are expected to be located in
|
||
|
`/etc/matrix-synapse/workers`. If you want to use a different location you have
|
||
|
to edit the provided `*.service` files accordingly.
|
||
|
|
||
|
## Bots and Bridges
|
||
|
|
||
|
Most bots and bridges do not care if the homeserver goes down or is restarted.
|
||
|
Depending on the implementation this may crash them though. So look up the docs
|
||
|
or ask the community of the specific bridge or bot you want to run to make sure
|
||
|
you choose the correct setup.
|
||
|
|
||
|
Whichever configuration you choose, after the setup the following will enable
|
||
|
automatically starting (and potentially restarting) your bot/bridge with the
|
||
|
`matrix.target`.
|
||
|
|
||
|
```
|
||
|
systemctl enable <yourBotOrBridgeName>.service
|
||
|
```
|
||
|
|
||
|
**Note** that from an inactive synapse the bots/bridges will only be started with
|
||
|
synapse if you start the `matrix.target`, not if you start the
|
||
|
`matrix-synapse.service`. This is on purpose. Think of `matrix-synapse.service`
|
||
|
as *just* synapse, but `matrix.target` being anything matrix related, including
|
||
|
synapse and any and all enabled bots and bridges.
|
||
|
|
||
|
### Start with synapse but ignore synapse going down
|
||
|
|
||
|
If the bridge can handle shutdowns of the homeserver you'll want to install the
|
||
|
service in the `matrix.target` and optionally add a
|
||
|
`After=matrix-synapse.service` dependency to have the bot/bridge start after
|
||
|
synapse on starting everything.
|
||
|
|
||
|
In this case the service file should look like this.
|
||
|
|
||
|
```
|
||
|
[Unit]
|
||
|
# ...
|
||
|
# Optional, this will only ensure that if you start everything, synapse will
|
||
|
# be started before the bot/bridge will be started.
|
||
|
After=matrix-synapse.service
|
||
|
|
||
|
[Service]
|
||
|
# ...
|
||
|
|
||
|
[Install]
|
||
|
WantedBy=matrix.target
|
||
|
```
|
||
|
|
||
|
### Stop/restart when synapse stops/restarts
|
||
|
|
||
|
If the bridge can't handle shutdowns of the homeserver you'll still want to
|
||
|
install the service in the `matrix.target` but also have to specify the
|
||
|
`After=matrix-synapse.service` *and* `BindsTo=matrix-synapse.service`
|
||
|
dependencies to have the bot/bridge stop/restart with synapse.
|
||
|
|
||
|
In this case the service file should look like this.
|
||
|
|
||
|
```
|
||
|
[Unit]
|
||
|
# ...
|
||
|
# Mandatory
|
||
|
After=matrix-synapse.service
|
||
|
BindsTo=matrix-synapse.service
|
||
|
|
||
|
[Service]
|
||
|
# ...
|
||
|
|
||
|
[Install]
|
||
|
WantedBy=matrix.target
|
||
|
```
