redhat yum源安装与配置
YUM是RedhatLinux在线安装更新及软件的工具，但是这是RHEL5的收费功能，如果没有购买Redhat的服务时不能使用RHEL5的更新源的，会提示注册。
由于CentOS是从Redhat演化而来的免费Linux版本，因此可以利用CentOS的yum更新源来实现RHEL5的YUM功能。配置方法如下：
检查yum是否安装，默认情况下都是安装好的，总共4各包。
[root@linux-a~]#rpm-qa|grepyum
yum-metadata-parser-1.0-8.fc6
yum-3.0.1-5.el5
yum-rhn-plugin-0.4.3-1.el5
yum-updatesd-3.0.1-5.el5
配置yum更新源
创建/etc/yum.repos.d/CentOS-Base.repo文件，定义yum更新源，这里使用的是上海交大的CentOS更新源
[root@linux-a~]#vi/etc/yum.repos.d/CentOS-Base.repo
