yum install -y tigervnc-server
cp /lib/systemd/system/[email protected] /etc/systemd/system/vncserver@:1.service

3.修改服务文件
vim vncserver@:1.service
[Unit]

4.加载服务配置
systemctl daemon-reload

systemctl enable vncserver@:1.service
6.启动服务
systemctl restart vncserver@:1.service

vnc客户端登陆：IP:5901

8.黑屏处理
通常是桌面软件问题（GNOUM、Xwindow）
1）安装 MATE 桌面：

yum groups install "MATE Desktop"

2）修改 xstartup 文件

vim ~/.vnc/xstartup

!/bin/sh

[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
[ -r HOME/.Xresources
xsetroot -solid grey
vncconfig -iconic &
x-terminal-emulator -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &
mate-session &

3）重启服务
systemctl restart vncserver@:1.service
