如果服务器是自己的，并且机器就在身边，那什么都不用说了，缺少gcc顶多就是重新放入安装盘，把开发工具包安装上。但是如果是租的服务器，托管服务 方那帮人又搞不懂你说的啥子gcc，要安装gcc实在是太麻烦了。你得去找gcc相关的包，版本号还得必须对应上，否则不兼容。最近给一个朋友装gcc， 着实头疼了一把。后来发现yum这个好东西，只需要执行一个命令，所有的烦恼都解除了。
朋友的系统是CentOS 5 的，托管商没给安装gcc，于是使用如下两个命令就可把gcc，gcc-c++统统安装上：
yum -y install gcc yum -y install gcc-c++
yum会自动查找软件的相关依赖包，自动下载安装，全过程轻松愉快。特此记录一下。
[root@localhost Jorcen]# yum -y install gcc
