CentOS 7 systemd 禁用 gnome 启动

平时自己家里的 CentOS 7 不需要图形界面,所以禁用

查看当前启动模式,发现时界面模式

[root@192 ~]# systemctl get-default 
graphical.target

将界面模式改为多用户无界面模式,重启生效

[root@192 ~]# systemctl set-default multi-user.target

Created symlink from /etc/systemd/system/default.target to /usr/lib/systemd/system/multi-user.target.
