如何更改CentOS7的启动级别

在虚拟机新安装了个CentOS7，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

 

然后发现跟之前不一样了，在inittab设置不再生效：

 1 # inittab is no longer used when using systemd.
 2 #
 3 # ADDING CONFIGURATION HERE WILL HAVE NO EFFECT ON YOUR SYSTEM.
 4 #
 5 # Ctrl-Alt-Delete is handled by /usr/lib/systemd/system/ctrl-alt-del.target
 6 #
 7 # systemd uses 'targets' instead of runlevels. By default, there are two main targets:
 8 #
 9 # multi-user.target: analogous to runlevel 3
10 # graphical.target: analogous to runlevel 5
11 #
12 # To view current default target, run:
13 # systemctl get-default
14 #
15 # To set a default target, run:
16 # systemctl set-default TARGET.target
17 #

 

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

按照上面的提示，查看当前的默认target输入命令：

 

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

 


当前为graphical.target

修改为命令模式multi-user.target：

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

 

查看一下当前，发现得到预期要求：

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

 

最后重启发现，果然是命令模式~~
