VNC 使您能够远程訪问和控制您的计算机从还有一计算机或移动设备上，不管你在世界的不论什么地方。
常见的使用情形，包含给同事和朋友提供桌面支持、远程管理您的服务器。
将 VNC Server部署到您想要控制计算机。使用VNC Viewer连接到你想要控制的计算机。
安装服务：
yum install tigervnc-server
这名称有点怪，没用过不知道的话是推測不到的。[root@localhost ~]# yum install tigervnc-server Loaded plugins: fastestmirror, refresh-packagekit, security Loading mirror speeds from cached hostfile * base: mirror.bit.edu.cn * extras: mirrors.yun-idc.com * updates: mirrors.yun-idc.com Setting up Install Process Resolving Dependencies --> Running transaction check ---> Package tigervnc-server.x86_64 0:1.1.0-8.el6_5 will be installed --> Finished Dependency Resolution Dependencies Resolved =============================================================================================================================================================================================== Package Arch Version Repository Size =============================================================================================================================================================================================== Installing: tigervnc-server x86_64 1.1.0-8.el6_5 updates 1.1 M Transaction Summary =============================================================================================================================================================================================== Install 1 Package(s) Total download size: 1.1 M Installed size: 2.9 M Is this ok [y/N]: y Downloading Packages: tigervnc-server-1.1.0-8.el6_5.x86_64.rpm | 1.1 MB 00:02 Running rpm_check_debug Running Transaction Test Transaction Test Succeeded Running Transaction Installing : tigervnc-server-1.1.0-8.el6_5.x86_64 1/1 Verifying : tigervnc-server-1.1.0-8.el6_5.x86_64 1/1 Installed: tigervnc-server.x86_64 0:1.1.0-8.el6_5 Complete!
执行并设置password：
vncserver :1
输入password。会生成相关的文件
[root@localhost ~]# vncserver :1 You will require a password to access your desktops. Password: Verify: xauth: creating new authority file /root/.Xauthority New 'localhost.localdomain:1 (root)' desktop is localhost.localdomain:1 Creating default startup script /root/.vnc/xstartup Starting applications specified in /root/.vnc/xstartup Log file is /root/.vnc/localhost.localdomain:1.log
配置用户
vim /etc/sysconfig/vncservers
最后一行增加：
VNCSERVERS="1:root" 多个用户用空格分开
有用命令
usage: vncserver [:<number>] [-name <desktop-name>] [-depth <depth>][-geometry <width>x<height>]
[-pixelformat rgbNNN|bgrNNN]
[-fp <font-path>]
[-fg]
<Xvnc-options>...
vncserver -kill <X-display>
vncserver -list
vncserver[:n]开服务
vncserver -list看有几个在执行
vncserver -kill :n 杀掉第几个x-display
vncpasswd 改动password
服务管理
service vncserver restart其他使用方法：/etc/init.d/vncserver {start|stop|restart|try-restart|status|force-reload}
chkconfig vncserver on 增加到自启动（chkconfig --level 35 vncserver on）
client连接
CentOS：使用TigerVNC Viewer 连接 ip:1
Windows：使用Real VNC Viewer 连接ip:1
输入password就可以訪问
