how to install gui to centos minimal
I have centos 6.3 minimal running as web server. I’m looking to install gui to my server to vnc to my server. You can install a group of packages with groupinstall command on centos, fedora, or red hat. All you have to do is to install the whole group of packages without installing many single packages at a time. Centos will install Gnome as default Gui.
Firstly you will need “X Window System” as the based for GUI
|
1
|
# yum groupinstall -y 'X Window System'
|
After that you can choose one of these available Desktop groups to install.
|
1
|
# yum groupinstall basic-desktop desktop-platform x11 fonts
|
or
|
1
|
# yum groupinstall "Desktop" "Desktop Platform" "X Window System" "Fonts"
|
To list all installed and available groups
|
1
|
# yum grouplist
|
To remove a Group of Packages
|
1
|
# yum groupremove "General Purpose Desktop"
|
To list all packages and descriptions of a group
|
1
|
# yum groupinfo "General Purpose Desktop"
|
There are also some optional packages if you want something more than a gui desktop environment

To boot to GUI directly without going to CLI mode, you need to edit /etc/inittab
