今天裝了下正式版的RHEL7，發現熟悉的inittab中沒有了修改默認運行級別，打開inittab如下
[root@localhost init.d]# vi /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 name>.target /etc/systemd/system/default.target
中間沒有了熟悉的 id:5:initdefault
RHEL7 使用systemd創建符號鏈接指向默認運行級別。
修改方法為：
1.首先刪除已經存在的符號鏈接
----------------------------------------------------------------------------------
rm /etc/systemd/system/default.target
----------------------------------------------------------------------------------
2.默認級別轉換為3(文本模式)
----------------------------------------------------------------------------------
ln -sf /lib/systemd/system/multi-user.target /etc/systemd/system/default.target
----------------------------------------------------------------------------------
或者默認級別轉換為5(圖形模式)
----------------------------------------------------------------------------------
ln -sf /lib/systemd/system/graphical.target /etc/systemd/system/default.target
----------------------------------------------------------------------------------
3.重啟
----------------------------------------------------------------------------------
reboot
