rhel6.5配置yum源步驟：
1.到 http://mirrors.163.com/centos/6/os/x86_64/Packages/下載三個yum的安裝包；
yum-plugin-fastestmirror-1.1.30-30.el6.noarch.rpm
yum-metadata-parser-1.1.2-16.el6.x86_64.rpm
yum-3.2.29-60.el6.centos.noarch.rpm
2.將三個安裝包同時進行安裝；
3.下線http://mirrors.163.com/.help/CentOS6-Base-163.repo，拷貝到/etc/yum.repo.d/下；
4.將CentOS6-Base-163.repo中所有的$releasever替換中6，sed -i 's/$releasever/6/g' CentOS6-Base-163.repo；
5.yum clean all、yum makecache、yum update。
