# 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

#查看当前系统默认
 systemctl get-default
#设置开机默认命令行界面：
 systemctl set-default multi-user.target
#设置开机默认图形化界面：
 systemctl set-default TARGET.target
