Linux Admin: SystemD

systemd loads up Linux faster than its the older sysvinit.

It manages Linux services


Use this to see the boot services

systemd-analyze


You can even put it into a graphic

systemd-analyze plot > SystemBoot.svg


Check the state of a service:

systemctl --state bluetooth


List the services:

systemctl -t service


Start and stop a service

systemctl start ssh

systemctl stop ssh

N.B. don't need the ".service" suffix


Check the status of a service

systemctl status ssh.service


 Control groups set limits on the system resources of services

An attacker trying to run crypto-mining software on your server might check and modify these limits

Why is this important? This is how we can create an account for users to access Linux servers.
