Passwordless restart of systemd services

Before anything else, you need to edit the rights, do this as your sudo/admin user:

$ sudo EDITOR=vim visudo

Adapt the line to your needs, first is the user, you want to give the passwordless permission to restart the service, last entry of the line is the name of the service.

# allow deployuser to restart the web services without needing a password
deployuser ALL=(ALL) NOPASSWD: /bin/systemctl restart myapponsystemd-worker.service
deployuser ALL=(ALL) NOPASSWD: /bin/systemctl restart myapponsystemd.service

Then log into your VPS/Server as your deployuser and try the restart.

$ sudo systemctl restart myapponsystemd.service
