[[email protected] ~]# more /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 /etc/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 set a default target, run:
#
# ln -sf /lib/systemd/system/.target /etc/systemd/system/default.target

設定預設啟動為多使用者字元界面：
[[email protected] ~]# 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'
檢視預設啟動的運作模式：
[[email protected] ~]# systemctl get-default
multi-user.target 字元模式

設定預設啟動為多使用者圖形界面：
[[email protected] ~]# systemctl set-default graphical.target
rm '/etc/systemd/system/default.target'
ln -s '/usr/lib/systemd/system/graphical.target' '/etc/systemd/system/default.target'
[[email protected] ~]#
檢視預設啟動的運作模式：
[[email protected] ~]#systemctl get-default
graphical.target 圖形模式
[[email protected] ~]#
從字元界面切換到圖形界面：
方法1：執行#startx
方法2：執行#systemctl isolate graphical.target
總結：可以看到更改預設級别的操作即先删除目前預設配置檔案，然後再建立連結檔案即可。
