< p > This is a setup for managing synapse with systemd, including support for
managing workers. It provides a < code > matrix-synapse< / code > service for the master, as
well as a < code > matrix-synapse-worker@< / code > service template for any workers you
require. Additionally, to group the required services, it sets up a
< code > matrix-synapse.target< / code > .< / p >
< p > See the folder < a href = "https://github.com/matrix-org/synapse/tree/develop/docs/systemd-with-workers/system/" > system< / a >
for the systemd unit files.< / p >
< p > The folder < a href = "https://github.com/matrix-org/synapse/tree/develop/docs/systemd-with-workers/workers/" > workers< / a >
contains an example configuration for the < code > federation_reader< / code > worker.< / p >

< p > See < a href = "../workers.html" > the worker documentation< / a > for information on how to set up the
configuration files and reverse-proxy correctly.
Below is a sample < code > federation_reader< / code > worker configuration file.< / p >
< pre > < code class = "language-yaml" > worker_app: synapse.app.federation_reader
worker_name: federation_reader1
worker_replication_host: 127.0.0.1

< p > Systemd manages daemonization itself, so ensure that none of the configuration

< p > The config files of all workers are expected to be located in
< code > /etc/matrix-synapse/workers< / code > . If you want to use a different location, edit
the provided < code > *.service< / code > files accordingly.< / p >

to < code > /etc/systemd/system< / code > .< / li >
< li > Run < code > systemctl daemon-reload< / code > to tell systemd to load the new unit files.< / li >
< li > Run < code > systemctl enable matrix-synapse.service< / code > . This will configure the
synapse master process to be started as part of the < code > matrix-synapse.target< / code >
target.< / li >
< li > For each worker process to be enabled, run < code > systemctl enable matrix-synapse-worker@< worker_name> .service< / code > . For each < code > < worker_name> < / code > , there
should be a corresponding configuration file.
< code > /etc/matrix-synapse/workers/< worker_name> .yaml< / code > .< / li >
< li > Start all the synapse processes with < code > systemctl start matrix-synapse.target< / code > .< / li >

systemctl restart matrix-synapse.target
# Stop Synapse and all workers

hardening options to any worker processes.< / p >
