The server must be in run level 3 before the installation can continue.

This tutorial will help you in solving the above error which cPANEL installation by changing your OS run level 5 to run level 3.

#systemctl get-default 
runlevel5.target

Let’s check the current run level for our centos OS based server by running following command

#systemctl get-default
runlevel5.target

P.S : You might get multi-user.target but still continue with the guide to solve your issue.

We will now change the default run level to 3 (it’s a mutli.user.target)

#systemctl set-default multi-user.target

Now confirm the current default run level

# systemctl get-default 
multi-user.target

Reboot and run the installation again

# reboot

You should be now able to complete the cPanel installation without the above error.
