[[email protected] ~]# systemctl get-default
graphical.target
[[email protected]~]# systemctl set-default multi-user.target
Removed symlink/etc/systemd/system/default.target.
Created symlink from/etc/systemd/system/default.target to /usr/lib/systemd/system/multi-user.target.
[[email protected]~]# systemctl get-default
multi-user.target
使用systemctl get-default可以獲得目前的預設target；
使用systemctl set-default可以設定預設target，target可以是graphical.target、multi-user.target。
//graphical.target表示開機将預設進入圖形界面
//multi-user.target表示開機将預設進入文本界面
rm -f /etc/systemd/system/default.target
設定指令行級别方法:
ln -sf /lib/systemd/system/runlevel3.target /etc/systemd/system/default.target
或
ln -sf /lib/systemd/system/multi-user.target /etc/systemd/system/default.target
或
systemctl set-default multi-user.target
改回視窗級别方法:
ln -sf /lib/systemd/system/runlevel5.target /etc/systemd/system/default.target
或
ln -sf /lib/systemd/system/graphical.target /etc/systemd/system/default.target
或
systemctl set-default graphical.target

網上各種政策将編輯 inittab檔案，從 5--》3即可，centos 7 之後 用系統
graphical.target
"/etc/inittab" 17L, 511C 17,1全部
# 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 runlevel5#
# To view current default target, run:
# systemctl get-default
#
# To set a default target, run:
# systemctl set-default TARGET.target
重新開機系統，就進入指令行模式了。
