Centos7修改启动的方式

在Centos7启动方式变化很大
之前的版本只需要修改/etc/inittab修改最后一个参数为3就可以了，而且模式有很多种，但是在centos7目前只有2种模式了。只有3和5了

[root@localhost ~]# cat /etc/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#

查看上面这个会直接懵了的，因为没有地方可以修改，我们可以查看到有一条命令
systemctl get-default 查看当前的模式
systemctl set-default TARGET.target 修改启动的模式

查看当前的启动模式

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

修改启动模式

[root@localhost ~]# systemctl set-default multi-user.targetRemoved symlink /etc/systemd/system/default.target.Created symlink from /etc/systemd/system/default.target to /usr/lib/systemd/system/multi-user.target.[root@localhost ~]# systemctl get-default multi-user.target
