一.刪除自帶的yum

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

二.從CentOS系統映象中提取rpm包,這裡以centos6.3_x64為例

這裡從映象包Packages目錄下提取如下rpm包:

三.安裝rpm包

注:這裡我為了方便就將所有提取出來的包放到我的VPS上供大家下載

# 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-3.2.29-30.el6.centos.noarch.rpm yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm

注：這一步要兩個一起安裝，要不會會出現如下錯誤：

----------------------------------------------

# rpm -ivh yum-3.2.29-30.el6.centos.noarch.rpm

# rpm -ivh PackageKit-yum-plugin-0.5.8-20.el6.x86_64.rpm

四.下載配置源：

# cd /etc/yum.repos.d/

五.測試

# yum version
