1.查看/etc/inittab如下:
# 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
新版本的CentOS 系统里使用’targets’ 取代了运行级别的概念。系统有两种默认的’targets’: 多用户.target 对应之前版本的3 运行级别; 而图形.target 对应之前的5运行级别。
2.查看默认的target,执行:
systemctl get-default
3.开机以命令模式启动,执行:
systemctl set-default multi-user.target
4.开机以图形界面启动,执行:
systemctl set-default graphical.target
