Centos 7 How To Change Runlevel

 On today's post I am going to walk you guys through the process of changing run-levels. This is ideal for situations for example where have a Centos installation that boots up into a graphical user interface and you wish to boot into Command Line only. So let's get down to business and do this :)

Checking The Current Runlevel

 You can still use the command "runlevel" to check the current run-level however here are two more ways to achieve the same goal.

 systemctl get-default

ll /etc/systemd/system/default.target

 Output Showing Current Runlevel:

 So graphical.target is my current runlevel this makes sense as I am running the Gnome desktop environment.

Before we go ahead and change the current runlevel we need will need to check out the available targets. We do this by issusing the following command:

# systemctl list-units --type=target

We will now go ahead and change the default runlevel to a runlevel3 

( this is will run nothing but a multi-user.target) 

We achieve this by issuing the following command:

# systemctl set-default multi-user.target 

We now confirm the changes / confirm the default runlevel:

# systemctl get-default

We should be now presented with the following as output indicating that the default runlevel has changed.

 multi-user.target

 Awesome stuff :) we have changed the runlevel all we need to do now is to reboot the system and check out our new runlevel in action:

reboot
