yum VNC后，启动时出错/usr/bin/Xvnc: symbol lookup error解决方法

安装的方法是先卸载原来的vnc，yum remove *vnc*

卸载完后，重新安装，安装方法 yum install *vnc*

然后启动vnc，直接执行vncserver回车，会提示输入6位密码：111111

关闭防火墙，/etc/init.d/iptables stop  

临时关闭setenforce=0

今天是2013.04.11最新centos版本是6.4，如果是centos6.4以下的版本执行命令：

yum install -y tigervnc* 后，执行启动会发现提示如下错误：

WARNING: The first attempt to start Xvnc failed, possibly because the font
catalog is not properly configured.  Attempting to determine an appropriate
font path for this system and restart Xvnc using that font path ...
Could not start Xvnc.

/usr/bin/Xvnc: symbol lookup error: /usr/bin/Xvnc: undefined symbol:
pixman_composite_trapezoids
/usr/bin/Xvnc: symbol lookup error: /usr/bin/Xvnc: undefined symbol:
pixman_composite_trapezoids

这是因为版本原因导致字体问题，需要安装、更新X11的包，或者看提示pixman安装此包。

命令如下：yum install pixman pixman-devel libXfont －y

此问题另外一种解决方案为：用本地IOS（与系统对应的版本）为yum源，可解决此问题！

vnc sever

Unable to launch VNCServer due to fontpath issues on CentOS 6
When trying out VNCServer on both CentOS 6.2 and CentOS 6.3

$ vncserver

WARNING: The first attempt to start Xvnc failed, possibly because the font
catalog is not properly configured.  Attempting to determine an appropriate

Could not start Xvnc.

/usr/bin/Xvnc: symbol lookup error: /usr/bin/Xvnc: undefined symbol:

The solution is to Install / Update
The Pixel manipulation library development package (pixman, pixman-devel)
X font handling library for server (libXfont)
Interestingly, the default installation of X Windows misses out these packages
