1、检出是否安装VNC
[[email protected] ~]# rpm -q tigervnc tigervnc-server
2、安装安装X-Window
[[email protected] ~]# yum check-update
[[email protected] ~]# yum groupinstall “X Window System”
[[email protected] ~]# yum install gnome-classic-session gnome-terminal nautilus-open-terminal control-center liberation-mono-fonts
[[email protected] ~]# unlink /etc/systemd/system/default.target
[[email protected] ~]#ln -sf /lib/systemd/system/graphical.target /etc/systemd/system/default.target
[[email protected] ~]# reboot #重启机器
3.安装VNC
[[email protected] ~]# # yum install tigervnc-server -y
4、从VNC备份库中复制service文件到系统service服务管理目录下【原文这里存在错误,不是创建[email protected]:1.service文件夹】
[[email protected] ]# cp /lib/systemd/system/[email protected] /etc/systemd/system/[email protected]:1.service

#复制并被重命名为[email protected]:1.service
5 修改[email protected]:1.service文件
#cd /etc/systemd/system/[email protected]:1.service
#vi [email protected]:1.service
33:[Unit]
34:Description=Remote desktop service (VNC)
35:After=syslog.target network.target
37:[Service]
38:Type=forking
39:User=root

43:ExecStart=/sbin/runuser -l root -c “/usr/bin/vncserver %i”
44:PIDFile=/root/.vnc/%H%i.pid
45:ExecStop=-/usr/bin/vncserver -kill %i
47:[Install]
48:WantedBy=multi-user.target
6.修改文件使配置生效：

systemctl daemon-reload

7.为[email protected]:1.service设置密码

vncpasswd

启动VNC

systemctl enable [email protected]:1.service #设置开机启动

systemctl start [email protected]:1.service #启动vnc会话服务

systemctl status [email protected]:1.service #查看nvc会话服务状态

systemctl stop [email protected]:1.service #关闭nvc会话服务

netstat -lnt | grep 590* #查看端口
