How To Install GUI on Red Hat or CentOS

So you installed Red Hat or CentOS 7 using minimal install and all has been well. Now, you find that you’d like to install the GUI and don’t want to re-install the OS from scratch. No problem.

Start by installing yum-utils

yum install yum-utils

To list software groups, enter

yum grouplist

Output will be similar to this

Loaded plugins: fastestmirror
There is no installed groups file.
Maybe run: yum groups mark convert (see man yum)
Loading mirror speeds from cached hostfile

 * extras: mirror.fdcservers.net

   Infrastructure Server

   Basic Web Server
   Virtualization Host
   Server with GUI
   GNOME Desktop

To install “Server with GUI” group, enter:

yum groupinstall "Server with GUI"

Once the installation is finished, you need to change system’s runlevel to runlevel 5. Changing runlevel on RHEL 7 and CentOS 7 is done by use of systemctl command.

systemctl enable graphical.target --force

Depending on your previous installations you may need to accept Redhat License after you reboot your system.
