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：
vim /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-defaultgraphical.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-defaultmulti-user.target [root@localhost ~]#
最后重启发现，果然是命令模式
