RHEL7 图形界面改成多用户模式

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
