CentOS下修復yum安裝工具
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

網上檢視後發現yum命令依賴python解析，所以將yum命令指向回原來的python，即python_old。
# vi /usr/bin/yum #開啟yum命令檔案，更改第一行指令碼啟動地址
# yum --help #檢視yum命令正常大功告成.....
