redhat6 yum安装与配置

1.删除redhat原有的yum 

rpm -aq|grep yum|xargs rpm -e --nodeps 

2.下载yum安装文件

注意，如果下载时找不到文件，就登录到：http://mirrors.163.com/centos/6/os/x86_64/ 上查找相应的文件。然后再下载。

wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-3.2.29-60.el6.centos.noarch.rpm
wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-metadata-parser-1.1.2-16.el6.x86_64.rpm 
wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.30-30.el6.noarch.rpm 
wget http://mirrors.163.com/centos/6/os/x86_64/Packages/python-iniparse-0.3.1-2.1.el6.noarch.rpm
3.进行安装yum 

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-3.2.29-60.el6.centos.noarch.rpm yum-plugin-fastestmirror-1.1.30-30.el6.noarch.rpm

注意最后两个包必需同时安装，否则会相互依赖
