一：刪除已有的yum

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

二：安裝新的yum

wget /> wget /> wget />

rpm -ivh yum-metadata-parser-1.1.2-16.el6.x86_64.rpm yum-3.2.29-60.el6.centos.noarch.rpm yum-plugin-fastestmirror-1.1.30-30.el6.noarch.rpm

三：檔案配置

cd /etc/yum.repos.d/
wget />
vim CentOS6-Base-163.repo 檔案中的所有$release用6.6代替

[base]
name=CentOS-6.6 - Base - 163.com
baseurl= /> #mirrorlist= /> gpgcheck=1
gpgkey= />

#released updates

#contrib - packages by Centos Users
