synctl(1) -- Synapse server control interface
|
|
=============================================
|
|
|
|
## SYNOPSIS
|
|
Start, stop or restart synapse server.
|
|
|
|
`synctl` {start|stop|restart} [configfile] [-w|--worker=<WORKERCONFIG>] [-a|--all-processes=<WORKERCONFIGDIR>]
|
|
|
|
## DESCRIPTION
|
|
|
|
**synctl** can be used to start, stop or restart Synapse server. The
|
|
control operation can be done on all processes or a single worker
|
|
process.
|
|
|
|
## OPTIONS
|
|
|
|
* `action`:
|
|
The value of action should be one of `start`, `stop` or `restart`.
|
|
|
|
* `configfile`:
|
|
Optional path of the configuration file to use. Default value is
|
|
`homeserver.yaml`. The configuration file must exist for the
|
|
operation to succeed.
|
|
|
|
* `-w`, `--worker`:
|
|
|
|
Perform start, stop or restart operations on a single worker.
|
|
Incompatible with `-a`|`--all-processes`. Value passed must be a
|
|
valid worker's configuration file.
|
|
|
|
* `-a`, `--all-processes`:
|
|
|
|
Perform start, stop or restart operations on all the workers in
|
|
the given directory and the main synapse process. Incompatible
|
|
with `-w`|`--worker`. Value passed must be a directory containing
|
|
valid work configuration files. All files ending with `.yaml`
|
|
extension shall be considered as configuration files and all other
|
|
files in the directory are ignored.
|
|
|
|
## CONFIGURATION FILE
|
|
|
|
Configuration file may be generated as follows:
|
|
|
|
$ python -B -m synapse.app.homeserver -c config.yaml --generate-config --server-name=<server name>
|
|
|
|
## ENVIRONMENT
|
|
|
|
* `SYNAPSE_CACHE_FACTOR`:
|
|
Synapse's architecture is quite RAM hungry currently - a lot of
|
|
recent room data and metadata is deliberately cached in RAM in
|
|
order to speed up common requests. This will be improved in
|
|
future, but for now the easiest way to either reduce the RAM usage
|
|
(at the risk of slowing things down) is to set the
|
|
SYNAPSE_CACHE_FACTOR environment variable. Roughly speaking, a
|
|
SYNAPSE_CACHE_FACTOR of 1.0 will max out at around 3-4GB of
|
|
resident memory - this is what we currently run the matrix.org
|
|
on. The default setting is currently 0.1, which is probably around
|
|
a ~700MB footprint. You can dial it down further to 0.02 if
|
|
desired, which targets roughly ~512MB. Conversely you can dial it
|
|
up if you need performance for lots of users and have a box with a
|
|
lot of RAM.
