Systemd 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
directory (location may differ by what distributions you run).
[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
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
from the terminal.
You can also reload all the workers by invoking systemctl reload rqworker@*.
