1.  安装VNC：
    
        [root@CentOS-x86-64-DVD-1804-Desktop ~]# yum -y install tigervnc-server
2.  启动VNC并设置密码：
    
        [root@CentOS-x86-64-DVD-1804-Desktop ~]# vncserver
        
        You will require a password to access your desktops.
        
        Password:
        Verify:
        Would you like to enter a view-only password (y/n)? y
        Password:
        Verify:
        xauth:  file /root/.Xauthority does not exist
        
        New 'CentOS-x86-64-DVD-1804-Desktop:1 (root)' desktop is CentOS-x86-64-DVD-1804-Desktop:1
        
        Creating default startup script /root/.vnc/xstartup
        Creating default config /root/.vnc/config
        Starting applications specified in /root/.vnc/xstartup
        Log file is /root/.vnc/CentOS-x86-64-DVD-1804-Desktop:1.log
3.  创建窗口1的开机启动：
    
        [root@CentOS-x86-64-DVD-1804-Desktop ~]# cp /lib/systemd/system/vncserver@.service /etc/systemd/system/vncserver@:1.service
4.  修改窗口1的开机启动：
    
        [root@CentOS-x86-64-DVD-1804-Desktop ~]# vim /etc/systemd/system/vncserver@:1.service
    
    原始内容：
    
        [Unit]
        Description=Remote desktop service (VNC)
        After=syslog.target network.target
        
        [Service]
        Type=forking
        
        # Clean any existing files in /tmp/.X11-unix environment
        ExecStartPre=/bin/sh -c '/usr/bin/vncserver -kill %i > /dev/null 2>&1 || :'
        ExecStart=/usr/sbin/runuser -l <USER> -c "/usr/bin/vncserver %i"
        PIDFile=/home/<USER>/.vnc/%H%i.pid
        ExecStop=/bin/sh -c '/usr/bin/vncserver -kill %i > /dev/null 2>&1 || :'
        
        [Install]
        WantedBy=multi-user.target
    
    修改为（root用户）：
    
        [Unit]
        Description=Remote desktop service (VNC)
        After=syslog.target network.target
        
        [Service]
        Type=forking
        
        # Clean any existing files in /tmp/.X11-unix environment
        ExecStartPre=/bin/sh -c '/usr/bin/vncserver -kill %i > /dev/null 2>&1 || :'
        ExecStart=/usr/sbin/runuser -l root -c "/usr/bin/vncserver %i"
        PIDFile=/root/.vnc/%H%i.pid
        ExecStop=/bin/sh -c '/usr/bin/vncserver -kill %i > /dev/null 2>&1 || :'
        
        [Install]
        WantedBy=multi-user.target
5.  设置窗口1的开机启动：
    
        [root@CentOS-x86-64-DVD-1804-Desktop ~]# systemctl enable vncserver@:1.service
6.  开启窗口1：
    
        [root@CentOS-x86-64-DVD-1804-Desktop ~]# systemctl start vncserver@:1.service
7.  开启5900+？端口：  
    开启窗口1，开放端口5901（即5900+1）：  
    开启端口5901（需要开启防火墙）：
    
        [root@CentOS-x86-64-DVD-1804-Desktop ~]# firewall-cmd --zone=public --add-port=5901/tcp --permanent
    
    重启防火墙：
    
        [root@CentOS-x86-64-DVD-1804-Desktop ~]# systemctl restart firewalld.service
    
      
    查看已开放端口：
    
        [root@CentOS-x86-64-DVD-1804-Desktop ~]# firewall-cmd --list-ports
        5901/tcp
8.  打开VNC客户端：  
    输入地址后点回车：
