CentOS下使用YUM安装GCC、gcc-c++

在安装服务器的时候图快捷没有装一些系统软件，结果后来需要使用C++编译环境，由于系统本身没有C编译环境，所以不能下载源码进行安装，只能下载rpm文件进行安装，可是在使用rpm安装时，有许多的依赖安装包，又考虑到系统可以联网所以便使用了YUM安装GCC。
先说下YUM的原理吧：CentOS先将发布的软件放置到YUM服务器内，然后分析这些软件的依赖属性，将软件内的记录信息写下来。然后将这些信息分析后记录成软件相关性的清单列表。当客户端有软件安装的需求时，客户端主机会主动想网络上面的yum服务器请求下载要安装的软件和相关的依赖性属性的软件。
说了这么多直接上这两句高端大气上档次的语句吧：
yum -y install gcc
yum -y install gcc-c++
下图显示安装的过程：
