一、安装X Window System 注：若已经安装GUI则可跳过
1、切换到root用户，执行 yum groupinstall "X Window System"yum install gnome-classic-session gnome-terminal nautilus-open-terminal control-center liberation-mono-fonts dejavu-lgc-sans-fonts -y 安装相关组件
1 yum groupinstall -y "Fonts"
4、设置默认启动图形界面
1 2 # unlink /etc/systemd/system/default.target # ln -sf /lib/systemd/system/graphical.target /etc/systemd/system/default.target
5、重启系统生效
二、安装vnc服务 1、执行yum install tigervnc-server -y安装VNC服务器软件 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 # yum install tigervnc-server -y Loaded plugins: fastestmirror, langpacks Loading mirror speeds from cached hostfile * base: mirrors.aliyun.com * extras: mirrors.aliyun.com * updates: mirror.lzu.edu.cn base | 3.6 kB 00:00:00 extras | 3.4 kB 00:00:00 updates | 3.4 kB 00:00:00 Resolving Dependencies --> Running transaction check ---> Package tigervnc-server.x86_64 0:1.8.0-13.el7 will be installed --> Finished Dependency Resolution Dependencies Resolved =================================================================================================================================================================================================================== Package Arch Version Repository Size =================================================================================================================================================================================================================== Installing: tigervnc-server x86_64 1.8.0-13.el7 base 215 k Transaction Summary =================================================================================================================================================================================================================== Install 1 Package Total download size: 215 k Installed size: 509 k Downloading packages: tigervnc-server-1.8.0-13.el7.x86_64.rpm | 215 kB 00:00:00 Running transaction check Running transaction test Transaction test succeeded Running transaction Installing : tigervnc-server-1.8.0-13.el7.x86_64 1/1 Verifying : tigervnc-server-1.8.0-13.el7.x86_64 1/1 Installed: tigervnc-server.x86_64 0:1.8.0-13.el7 Complete!
2、配置VNC 在/etc/systemd/system目录里创建一个配置文件（可以将/lib/systemd/system/vncserver@.service拷贝一份配置文件范例过来）
1 cp /lib/systemd/system/vncserver@.service /etc/systemd/system/vncserver@:1.service
使用文本编辑器打开 /etc/systemd/system/vncserver@:1.service ，找到下面这几行，用自己的用户名替换掉 <USER>
1 2 3 4 5 User=<USER> PIDFile=/home/<USER>/.vnc/%H%i.pid 替换成 User=root PIDFile=/home/root/.vnc/%H%i.pid
重启systemd
vncpasswd设置VNC登录密码
执行vncserver开启一个VNC窗口
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 # vncserver You will require a password to access your desktops. Password: Verify: Would you like to enter a view-only password (y/n)? n A view-only password is not used xauth: file /root/.Xauthority does not exist New 'server:1 (root)' desktop is server: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/server:1.log
开启远程端口
1 2 3 4 5 6 7 8 # vncserver :1 A VNC server is already running as :1 New 'server:2 (root)' desktop is server:2 Starting applications specified in /root/.vnc/xstartup Log file is /root/.vnc/server:2.log
设置防火墙规则，允许访问VNC-SERVER的流量通过，并重启firewall服务使之生效
1 2 3 # firewall-cmd --permanent --add-service vnc-server # systemctl restart firewalld.service
三、客户端连接 VNC server 客户端可以使用官方，直接去 官网 下载，推荐使用 MobaXterm，集成常用 ssh，sftp 等功能。
地址栏填写：ip::5901。例如：172.20.8.31::5901
我们开启的是vncserver :1，而 vncserver 默认从5900开始，所以我们使用 5900+1 = 5901，注意需要两个 ::
接下来输入服务端设置的 vncserver 的密码就可以了。
注意关闭防火墙和selinux
