Copy the files into the recommended places.
- /etc/default/node-red
- /etc/systemd/system/[email protected]
Then to run the service for a user that is installed on your system do:
systemctl start node-red@jim node-red@bob
systemctl enable node-red@jim node-red@bob
It will not work if the user is not present on the system, or the port does not exist in the default file.
