配置Centos 6.5的yum源

42日43

问题：redhat 6.4 默认自带的 yum 源需要注册，才能更新。
解决方案：删除默认的yum源，手动配置Centos 6.5的yum源。
我这里的系统是RedHat 6.4的所以在 http://mirrors.163.com/centos/6/os/x86_64/Packages/  下载相关rpm包


1.首先查找系统自动安装了那些yum包
   # rpm -qa | grep yum
2.删除默认安装的yum包，不检查依赖关系

   # rpm -qa | grep yum | xargs rpm -e --nodeps
3.再次查看是否删除成功
   # rpm -qa | grep yum
4.下载新的yum包
   # wget http://mirrors.163.com/centos/6/ ... -2.1.el6.noarch.rpm  
   # wget http://mirrors.163.com/centos/6/ ... 6.centos.noarch.rpm
   # wget http://mirrors.163.com/centos/6/ ... 0-30.el6.noarch.rpm
   # wget http://mirrors.163.com/centos/6/ ... 2-16.el6.x86_64.rpm  
5.安装yum包

   # rpm -ivh  python-iniparse-0.3.1-2.1.el6.noarch.rpm
   # rpm -ivh  yum-metadata-parser-1.1.2-16.el6.x86_64.rpm
   # rpm -ivh  yum-3.2.29-69.el6.centos.noarch.rpm  yum-plugin-fastestmirror-1.1.30-30.el6.noarch.rpm
6.提供yum源的配置文件
   # cd /etc/yum.repos.d/
   # wget  http://mirrors.163.com/.help/CentOS6-Base-163.repo
   # vim CentOS6-Base-163.repo

PS：编辑配置文件，把文件里面的$release全部替换为版本号，即6.5 最后保存。
7.清除原有缓存
   # yum clean all
8.重建缓存，以提高搜索安装软件的速度
   # yum makecache
9.最后更新下
   # yum update
