Centos 设置开机进图形界面/终端

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"
