版本:CentOS 7

 

首先:

[root@localhost test]# 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 3
# graphical.target: analogous to runlevel 5
#
# To view current default target, run:
# systemctl get-default
#
# To set a default target, run:
# systemctl set-default TARGET.target
#
[root@localhost test]# 

 

其中:

multi-user.target 代表命令模式

graphical.target 代表图形界面

 

使用如下命令可以查看当前所处模式:

[root@localhost test]# systemctl get-default
multi-user.target

 

使用如下命令修改为图形界面模式:

systemctl set-default graphical.target

 

如果重启后还是没进入图形界面,可能系统里没有安装,使用如下命令安装即可:

yum groupinstall -y "GNOME Desktop"
