Remove GUI CentOS Linux OS

By Posted on

Several processes burdened one of host which has CentOS Linux operating system installed. In order to lose the burden, it is decided to erase and permanently uninstall every GUI stuff available and running in the host.

Below is several steps used to uninstall the GUI on the host :

1. Login to your server or host in a CLI (Command Line Interface) mode. It can be shown below : 

-bash-4.1#

The above bash prompt can be viewed in different form depends on your environment.

2. After getting a bash prompt, execute the following command to complete erase the GUI stuff. According to several sites, I can accomplish it by executing the following command in bash prompt : 

yum groupremove "X Windows System"

Below is the execution output of the above command : 

-bash-4.1#yum groupremove "X Windows System"

-bash-4.1#

3. Well, in my case apparently it is not working at all. So, I am trying another alternative command as follows : 

yum groupremove "GNOME Desktop Environment"

Below is the output execution of the above command : 

-bash-4.1# yum groupremove "GNOME Desktop Environment"

4. Well, it seems another dead end. So, I tried another command as follows : 

yum groupremove "KDE (K Desktop Environment)"

Below are the output of the above command execution : 

-bash-4.1# yum groupremove "KDE (K Desktop Environment)"
Loaded plugins: fastestmirror, refresh-packagekit, security

  1. So, I tried combining the command as follows :
-bash-4.1# yum groupremove "X Window System" "KDE (K Desktop Environment)"
Loaded plugins: fastestmirror, refresh-packagekit, security
Setting up Group Process
Loading mirror speeds from cached hostfile

Complete!
-bash-4.1#

Voila… at last the combined command worked !

6. Edit file which is defined the default runlevel of the operating system. The file exists in /etc/inittab. Below is the content which is needed to be edited. Edit it with your preferred editor. In this case, I am using vim editor as shown below :

-bash-4.1# vim /etc/inittab

This is the content of the file especially with the runlevel of multi-user GUI mode : 

id:5:initdefault:

The number ‘5’ indicate multi-user GUI mode for the operating system runlevel. Change it into the following content : 

id:3:initdefault:

The number ‘3’ indicate multi-user text-mode for the operating system runlevel.

  1. To make the change permanently, restart your host or server. Type the following alternative command :
reboot
shutdown -r now
