CentOS-7设置开机进入命令行界面（不进入图形界面）

CentOS-7设置开机进入命令行界面（不进入图形界面）

[root@localhost ~]# systemctl get-default
graphical.target
[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.
[root@localhost ~]# systemctl get-default
multi-user.target

使用systemctl get-default可以获得当前的默认target； 
使用systemctl set-default可以设置默认target，target可以是graphical.target、multi-user.target。

//graphical.target表示开机将默认进入图形界面 
//multi-user.target表示开机将默认进入文本界面

rm -f /etc/systemd/system/default.target

设置命令行级别方法: 
ln -sf /lib/systemd/system/runlevel3.target /etc/systemd/system/default.target 
或 
ln -sf /lib/systemd/system/multi-user.target /etc/systemd/system/default.target 
或 
systemctl set-default multi-user.target

改回窗口级别方法: 
ln -sf /lib/systemd/system/runlevel5.target /etc/systemd/system/default.target 
或 
ln -sf /lib/systemd/system/graphical.target /etc/systemd/system/default.target 
或 
systemctl set-default graphical.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

重启系统，就进入命令行模式了。
