CentOS 6.0 VNC远程桌面配置方法

<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
        VNC (Virtual Network Computing)是虚拟网络计算机的缩写。VNC 是一款优秀的远程控制工具软件，由著名的 AT&amp;T 的欧洲研究实验室开发的。VNC 是在基于 UNIX 和 Linux 操作系统的免费的开源软件，远程控制能力强大，高效实用，其性能可以和 Windows 和 MAC 中的任何远程控制软件媲美。 在 Linux 中，VNC 包括以下四个命令：vncserver，vncviewer，vncpasswd，和 vncconnect。大多数情况下我只需要其中的两个命令：vncserver 和 vncviewer。<br><br>
        VNC基本上是属于一种显示系统,也就是说他能将完整的窗口界面通过网络,传输到另一台计算机的屏幕上.Windows服务器中包含的”Terminal Server”、Symantec公司开发的收费软件PCAnywhere、近期流行的Teamviewer、国内的协通XT800、快递通KDT都是属于这种原理的设计，同时这些软件又在VNC的原理基础上做了各自相应改进，提高了易用性、连通率和可穿透内网（Teamviewer、协通XT800、KDT）.</p>

        必须明白：</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
        VNCServer在调用的时候，会根据你的配置来启用server端的监听端口，端口默认是从5900开始，再加上你的桌面号。</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
        •比如你的桌面号为1，则vnc的连接端口号为5900+1=5901<br>
        •比如你的桌面号为10000，则vnc的连接端口号为5900+10000=15900<br>
        下面配置VNC服务器，使用户（root）能够通过vnc客户端远程连接到Linux系统的图形界面(前提是你的服务器要安装桌面)</p>
