Id:3:initdefualt:

Indicates that the default RunLevel at startup is level 3. Can be modified to 5 and start on desktop. Restart takes effect.

Note that the default level cannot be set to 0, which will not be able to be opened or set to 6, which will continue to restart.

If the minimal installation user wants to start the graphical user interface, some packages need to be installed using the Yum tool:

# Yum Grouplist (displays information such as installed, available installation, etc.)

# lang=en

# yum Grouplist

# yum Groupinstall-y "Desktop"

# yum groupinstall-y "X window"

# init 5 = = StartX

# RunLevel
