一、需求背景

    查看系统版本信息：

    [root@XAYL YLMonitor]# cat /etc/os-release NAME="Anolis OS"VERSION="8.8"ID="anolis"ID_LIKE="rhel fedora centos"VERSION_ID="8.8"PLATFORM_ID="platform:an8"PRETTY_NAME="Anolis OS 8.8"ANSI_COLOR="0;31"HOME_URL="https://openanolis.cn/"

    需要在该服务器上配置VNC服务，以便通过远程进行操作。

    二、图形化UI安装

    安装图像化GUI界面并设置默认

        yum groupinstall "Server with GUI" -y

        systemctl set-default graphical

    三、配置VNC

    1、基础包安装

    yum install tigervnc-server tigervnc-server-module -y

    2、VNC配置初始化

      vncpasswd
      注释：
      Password:第一次输入密码
      Verify:确认密码
      Would you like to enter a view-only password (y/n)?：n

      3、手动启动vnc

          # vncserver

        [root@XAYL YLMonitor]# vncserver
        WARNING: vncserver has been replaced by a systemd unit and is now considered deprecated and removed in upstream.Please read /usr/share/doc/tigervnc/HOWTO.md for more information.
        New 'XAYL:1 (root)' desktop is XAYL:1
        Starting applications specified in /root/.vnc/xstartupLog file is /root/.vnc/XAYL:1.log

        四、将VNC集成到系统服务

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

          [Unit] Description=Remote Desktop VNC Service After=syslog.target network.target  [Service] Type=forking WorkingDirectory=/root User=root Group=root  ExecStartPre=/bin/sh -c '/usr/bin/vncserver -kill %i > /dev/null 2>&1 || :' ExecStart=/usr/bin/vncserver -autokill %i ExecStop=/usr/bin/vncserver -kill %i  [Install] WantedBy=multi-user.target

          五、服务常用命令

          // 启动服务

          # systemctl start vncserver@:1.service

          // 开机启动

          # systemctl enable vncserver@:1.service

          // 查看状态

          # systemctl status vncserver@:1.service

          手动终止命令：

              vncserver -kill :1

              vncserver :1 -geometry 1536x864

          六、连接测试

              防火墙先放行对应的端口。

              然后使用VNC客户端进行连接测试。

              地址输入：192.168.3.104:5901

          七、常见报错处理

          1、启动时提示：Make sure an X server isn't already running(EE)

            Fatal server error:(EE) Cannot establish any listening sockets - Make sure an X server isn't already running(EE) _XSERVTransSocketUNIXCreateListener: ...SocketCreateListener() failed_XSERVTransMakeAllCOTSServerListeners: server already running(EE) Fatal server error:(EE) Cannot establish any listening sockets - Make sure an X server isn't already running(EE)

            解决方案：

                touch /tmp/.X11-unix/X1

                chmod 777 /tmp/.X11-unix/X1

            2、启动时提示：(EE) Cannot establish any listening sockets - Make sure an X server isn't already r>

            解决方案：

                sudo pkill Xorg

            3、连接后提示：系统出错并无法恢复，请尝试注销。

                暂时未解决此问题。
