Redhat 7修改默认运行级别方法 --RHEL7使用systemd创建符号链接指向默认运行级别

今天装了下正式版的RHEL7，发现熟悉的inittab中没有了修改默认运行级别，打开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中间没有了熟悉的 id:5:initdefault RHEL7 使用systemd创建符号链接指向默认运行级别。修改方法为：
1.首先删除已经存在的符号链接
----------------------------------------------------------------------------------
rm /etc/systemd/system/default.target
----------------------------------------------------------------------------------
2.默认级别转换为3（文本模式）
----------------------------------------------------------------------------------
ln -sf /lib/systemd/system/multi-user.target /etc/systemd/system/default.target
----------------------------------------------------------------------------------
或者默认级别转换为5（图形模式）
----------------------------------------------------------------------------------
ln -sf /lib/systemd/system/graphical.target /etc/systemd/system/default.target
----------------------------------------------------------------------------------
3.重启
----------------------------------------------------------------------------------
reboot
