centos7 remote desktop vnc

Centos7 采用mini安装，如果想远程桌面，那就需要安装图形界面

# yum check-update
# yum groupinstall "X Window System"
# yum install gnome-classic-session gnome-terminal nautilus-open-terminal control-center liberation-mono-fonts
# unlink /etc/systemd/system/default.target

3, modify the configuration file

# vim /etc/systemd/system/vncserver@:1.service

#改成root用户启动，配置文件看起来这样的
