Systemd Unit

Note

This feature is still experimental. If you encounter any problem, please join our community to report it.

With both DEB and RPM package we ship the systemd unit, to start FerretDB automatically. If FerretDB is not installed yet, please refer to the 0 or 1 installation pages.

The unit file provides some basic environment variables as an example. They should be overwritten with the proper configuration.

[Service]
ExecStart=/usr/bin/ferretdb
Restart=on-failure

# Configure the FerretDB service with `systemctl edit ferretdb`.
# For more configuration options check https://docs.ferretdb.io/configuration/flags/

Environment="FERRETDB_POSTGRESQL_URL=postgres://127.0.0.1:5432/ferretdb"

You can modify them by using systemctl edit ferretdb command. This'll open a text editor that'll allow you to override the systemd options of choice. For example, if we want to use SQLite backend instead of PostgreSQL, we could write something like:

### Editing /etc/systemd/system/ferretdb.service.d/override.conf
### Anything between here and the comment below will become the new contents of the file

[Service]
Environment="FERRETDB_SQLITE_URL=file:/var/lib/ferretdb/data/"
Environment="FERRETDB_HANDLER=sqlite"

### Lines below this comment will be discarded
