Centos7 minimizes installation and then installs GNOME graphical interface

Install Desktop component package

Yum-y groupinstall "GNOME Desktop"

Yum-y groupinstall "X Window System"

Yum groupinstall "KDE Desktop" (centos6)

Start desktop startx

Startx

View the default run level

Systemctl get-default

Set the default run level

Systemctl set-default graphical.target

Rm'/ etc/systemd/system/default.target'

Ln-s'/ usr/lib/systemd/system/graphical.target''/ etc/systemd/system/default.target'

Note: you can query the running level of the graphical interface through the / etc/inittab file

[root@local ~] # cat / etc/inittab

# inittab is no longer used when using systemd.## ADDING CONFIGURATION HERE WILL HAVE NO EFFECT ON YOUR SYSTEM.## Ctrl-Alt-Delete is handled by / usr/lib/systemd/system/ctrl-alt-del.target## systemd uses' targets' instead of runlevels. By default, there are two main targets:## multi-user.target: analogous to runlevel operations graphical.target: analogous to runlevel 5 (runlevel 5) # # To view current default target, run:# systemctl get-default## To set a default target, run:# systemctl set-default TARGET.target

(besides)

Test whether the installation is successful

Use the init 5 command to enter the graphical interface, and if successful, you will enter the initial graphical interface.

How to uninstall the graphical interface

Use the group uninstall command yum groupremove + group package name, where the group package name is the one we installed above.
