Install Gnome desktop on the Character Interface
If you are installing the system on the Character interface, because you do not want to select a software package, you need to install the required software, such as the desktop, after installing the system.
In CentOs6.3, the name of the gonme Desktop package is changed to Desktop, which is the default Desktop of CentOs6.3. However, if you only install this group, it will not work. It lacks the support of the X protocol. When you start the desktop, the following error messages related to X will appear.
Xinit: No such file or directory (errno 2): no server "/usr/bin/X" in PATH
Xinit: No such file or directory (errno 2): unable to connect to X server
Xinit: No such process (errno 3): Server error.
Therefore, to install Gnome desktop on the Character interface, you need to install two groups.
[Root @ localhost ~] # Yum groupinstall "X Window System"
[Root @ localhost ~] # Yum groupinstall "Desktop"
Start Gnome Desktop
[Root @ localhost ~] # Startx
