centos7 默认进入系统命令行模式修改

systemctl get-default  #查看系统启动进入默认模式

 systemctl set-default graphical.target　　#改成默认进入 图形界面模式

 systemctl set-default multi-user.target　　#改成默认进入命令行模式

==================================

[root@localhost ~]# 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.

=====================================

网上各种策略将编辑 inittab文件，从 5--》3即可，centos 7 之后 用系统

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 runlevel 5
#
# To view current default target, run:
# systemctl get-default
#
# To set a default target, run:
# systemctl set-default TARGET.target
