1、卸载RHEL6自带的yum源

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

 

2、下载对应的安装包

# wget  http://mirror.centos.org/centos-6/6.5/os/x86_64/Packages/python-iniparse-0.3.1-2.1.el6.noarch.rpm    # wget  http://mirror.centos.org/centos-6/6.5/os/x86_64/Packages/yum-3.2.29-40.el6.centos.noarch.rpm    # wget  http://mirror.centos.org/centos-6/6.5/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm   #  wget  http://mirror.centos.org/centos-6/6.5/os/x86_64/Packages/yum-metadata-parser-1.1.2-16.el6.x86_64.rpm

 
3、安装软件包 

 # 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-3.2.29-40.el6.centos.noarch.rpm yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm

4、配置新的yum源

# cd /etc/yum.repos.d/ # wget  http://mirrors.163.com/.help/CentOS6-Base-163.repo # vi CentOS6-Base-163.repo  #编辑文件  把文件里面的$releasever全部替换为版本号，即6 最后保存！ [base] name=CentOS-6 - Base - 163.com baseurl=http://mirrors.163.com/centos/6/os/$basearch/ gpgcheck=1 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6 [updates] name=CentOS-6 - Updates - 163.com baseurl=http://mirrors.163.com/centos/6/updates/$basearch/ gpgcheck=1 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6 [extras] name=CentOS-6 - Extras - 163.com baseurl=http://mirrors.163.com/centos/6/extras/$basearch/ gpgcheck=1 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6   [centosplus] name=CentOS-6 - Plus - 163.com baseurl=http://mirrors.163.com/centos/6/centosplus/$basearch/ gpgcheck=1 enabled=0 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6 [contrib] name=CentOS-6 - Contrib - 163.com baseurl=http://mirrors.163.com/centos/6/contrib/$basearch/ gpgcheck=1 enabled=0 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6

 

5、报错信息如下：

# yum makecache There was a problem importing one of the Python modules required to run yum. The error leading to this problem was:    No module named yum Please install a package which provides this module, or verify that the module is installed correctly.
