新装了一个虚拟机，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：
# 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~~
