Centos 从多用户终端切换到桌面

1. 问题

如何从centos的多用户界面，切换到桌面呢？

2. 解决办法

2.1 tty 命令

tty - print the file name of the terminal connected to standard input

打印连接到标准输出的终端文件名。

• 在桌面的terminal下执行tty命令：

[littlelawson@server4 ~]$ tty
/dev/pts/0

• 在xshell环境中执行 tty 命令【命令行模式】

[littlelawson@server4 ~]$ tty
/dev/pts/1

2.2 查看 /etc/inittab文件

[root@server4 zookeeper-3.4.11]# 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@server4 zookeeper-3.4.11]# systemctl get-default
multi-user.target
[root@server4 zookeeper-3.4.11]# systemctl set-defaultgraphical.target
Unknown operation 'set-defaultgraphical.target'.
[root@server4 zookeeper-3.4.11]# systemctl set-default graphical.target
Removed symlink /etc/systemd/system/default.target.
Created symlink from /etc/systemd/system/default.target to /usr/lib/systemd/system/graphical.target.

重启

[root@server4 zookeeper-3.4.11]# reboot

这样就可以从命令行界面切换到了桌面模式。
