Running RQ Workers Under systemd
[systemd][1] is process manager that's built into many popular Linux distributions.
To run multiple workers under systemd, you'll first need to create a unit file.
We can name this file rqworker@.service, put this file in /etc/systemd/system
on Ubuntu. Where you put this file may differ by what OS you run.
{% highlight ini %} [Unit] Description=RQ Worker Number %i After=network.target
[Service] Type=simple WorkingDirectory=/path/to/working_directory Environment=LANG=en_US.UTF-8 Environment=LC_ALL=en_US.UTF-8 Environment=LC_LANG=en_US.UTF-8 ExecStart=/path/to/rq worker -c config.py ExecReload=/bin/kill -s HUP $MAINPID ExecStop=/bin/kill -s TERM $MAINPID PrivateTmp=true Restart=always
[Install] WantedBy=multi-user.target {% endhighlight %}
If your unit file is properly installed, you should be able to start workers by
invoking systemctl start rqworker@1.service, systemctl start rqworker@2.service.
You can also reload all the workers by invoking systemctl reload rqworker@*.
