CentOS7修改默认运行级别

图形界面启动太慢，想调整一下按照以前的经验改运行级别，输入：

vi /etc/inittab

1进入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#

2仔细读一下上面的提示

multi-user.target 类似与之前的runlevel 3
graphical.target 类似与之前的runlevel 5

3按照上面的提示，查看当前的默认target输入命令：

[root@localhost ~]# systemctl get-defaultgraphical.target[root@localhost ~]# 

4当前为graphical.target

5修改为命令模式multi-user.target：

[root@localhost ~]# systemctl set-default multi-user.targetrm '/etc/systemd/system/default.target'ln -s '/usr/lib/systemd/system/multi-user.target' '/etc/systemd/system/default.target'[root@localhost ~]# 

6查看一下当前

[root@localhost ~]# systemctl get-defaultmulti-user.target[root@localhost ~]# 

 

7重启后发现，是命令行模式 呵呵呵！！！
