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.
