rhel 5 添加 centos 源

先卸载原rhel的yum

别心疼。。。反正你不会去买rhn的

su

进入root下

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

没错是原版的yum全卸载

看自己的系统是x86的还是x64的

uname -a

有 x86_64的用这组地址的rpm

wget http://vault.centos.org/5.11/os/x86_64/CentOS/yum-fastestmirror-1.1.16-21.el5.centos.noarch.rpm

下载后安装

最后下自己回车

cd /etc/yum.repos.d/

下载网上别人发的这些centos 5.11的源文件

导入centos的key

rpm -import http://vault.centos.org/RPM-GPG-KEY-CentOS-5

然后yum就可以用了。。。

如果出现

There was a problem importing one of the Python modules
required to run yum. The error leading to this problem was:

   /usr/lib/python2.4/site-packages/_sqlitecache.so: wrong ELF class: ELFCLASS32

Please install a package which provides this module, or
verify that the module is installed correctly.

It's possible that the above module doesn't match the
current version of Python, which is:
2.4.3 (#1, Jun 11 2009, 14:09:37) 
[GCC 4.1.2 20080704 (Red Hat 4.1.2-44)]

If you cannot solve this problem yourself, please go to 
the yum faq at:
  http://wiki.linux.duke.edu/YumFaq

基本上就x86_64系统用了x86的yum-metadata-parser导致的，卸载重装就好了。。。
