CentOS7修改默认运行级别

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：# 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~~更多CentOS相关信息见CentOS 专题页面 http://www.linuxidc.com/topicnews.aspx？tid=14本文永久更新链接地址
