How to run service not as root

Question

I created successfully a service on my Linux RedHat by copy the Unit-File to /usr/lib/systemd/system/mediation.service

I can successfully start/stop/enable/... the service with

systemctl enable mediation
systemctl start mediation
etc.

However, since systemctl is usually executed by root, my application runs also as root. How can I configure the service that it runs under a different (non-privileged) user?

Solution

Use:

User=myuser

In your unit file.

This is documented in man systemd.exec

Also, custom files should not go in /usr/lib/systemd/system, they should go in /etc/systemd/system. The former is where packages install their files. The later is where system administrators should put their files.

What if you separately add the commands to the sudoers file of the non-root user you want to run as?
