CentOS7修改默認運行級別

新裝了一個虛擬機，圖形界面啓動太慢，想調整一下按照之前的經驗改運行級別，輸入：

vi /etc/inittab

而後發現跟以前不同了，在inittab設置再也不生效：

# 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
#

仔細讀一下上面的提示

multi-user.target 相似與以前的runlevel 3
graphical.target 相似與以前的runlevel 5

按照上面的提示，查看當前的默認target輸入命令：

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

當前爲graphical.target

修改成命令模式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 ~]# 

查看一下當前，發現獲得預期要求：

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

 

最後重啓發現，果真是命令模式~~
