yum install tigervnc-server tigervnc vnc vnc-server

cp /lib/systemd/system/vncserver@.service /etc/systemd/system/vncserver@:1.service

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

    找到这一行

    ExecStart=/sbin/runuser -l <USER> -c "/usr/bin/vncserver %i"

    PIDFile=/home/<USER>/.vnc/%H%i.pid

    这里直接用root 用户登录，所以我替换成

    ExecStart=/sbin/runuser -l root -c "/usr/bin/vncserver %i"

    PIDFile=/root/.vnc/%H%i.pid

systemctl daemon-reload

vncpasswd

    Would you like to enter a view-only password (y/n)? n             #注意表示"是否输入一个只能查看的密码，选择否",否则连接vnc会出现黑屏

systemctl daemon-reload

systemctl enable vncserver@:1.service

systemctl start vncserver@:1.service

systemctl stop vncserver@:1.service

systemctl status vncserver@:1.service

locale -a|grep zh_CN #查看语言支持

vim /etc/locale.conf  #修改为zh-CN.utf-8

reboot
