1、安装VNC

yum install -y tigervnc tigervnc-server

2、安装安装X-Window

# 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
# ln -sf /lib/systemd/system/graphical.target /etc/systemd/system/default.target
# reboot

3、从VNC备份库中复制service文件到系统service服务管理目录下

# cp /lib/systemd/system/[email protected] /etc/systemd/system/vncserver@:1.service

4、修改vncserver@:1.service文件

[Unit]
Description=Remote desktop service (VNC)
After=syslog.target network.target

[Service]
Type=forking
user=root

ExecStartPre=-/usr/bin/vncserver -kill %i
ExecStart=/sbin/runuser -l root -c "/usr/bin/vncserver %i" 
PIDFile=/root/.vnc/%H%i.pid
ExecStop=-/usr/bin/vncserver -kill %i

[Install]
WantedBy=multi-user.targe

修改文件使配置生效：

# systemctl daemon-reload

5、为vncserver@:1.service设置密码

# vncpasswd

6、启动VNC

# systemctl enable vncserver@:1.service 

# systemctl start vncserver@:1.service #启动vnc会话服务

# systemctl status vncserver@:1.service 

# systemctl stop vncserver@:1.service #关闭nvc会话服务

# netstat -lnt | grep 590*     

tcp        0      0 0.0.0.0:5901            0.0.0.0:*               LISTEN     
tcp        0      0 0.0.0.0:5901            0.0.0.0:*               LISTEN

# yum whatprovides "*/xhost"
# xhost +

8、windows使用VNC链接到图形化界面

1、链接图形化界面服务器的5901端口
