替换 RHEL5的yum源为CentOS5源，亲测线上系统可用

 

最近安装nagios+pnp，各种依赖包啊。rrdtool肿么装的这么费劲，后来实在扛不住了，还是修改rhel的源吧，把yum源搞成centos的不就ok了！哈哈。然后就从网上一顿猛搜，发现“Ayou”老师的文章很靠谱，很有帮助，这里是看“Ayou”老师的文章搭出来的。虽然不是太难，但是找这个CentOS-Base.repo还是要靠“ayou”老师的文章，所以，感谢下“Ayou”老师。顺便推荐“Ayou”老师的博客，有很多很多好的文章，篇幅很短，但很精练。

由于我的系统环境是x86_64的，“Ayou”老师的路径是i386的，所以稍微改了一点Ayou老师源地址的路径，还有一点就是把gpgkey的路径换成了163的路径，因为感觉每次访问gpgkey都要去国外的服务器跑一圈是不是有点绕了。当然把这个gpgkey放在本地也是合适的，但是，个人认为在没有互联网访问的情况下，yum源本身就是无法连通的，这个gpgkey也确实就没有必要存在，所以这里就没有拿回本地来。

1、卸载掉RHEL原有的yum包

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

2、下载centos的yum安装文件

wget http://mirrors.163.com/centos/5/os/x86_64/CentOS/python-iniparse-0.2.3-4.el5.noarch.rpm
wget http://mirrors.163.com/centos/5/os/x86_64/CentOS/yum-3.2.22-39.el5.centos.noarch.rpm
wget http://mirrors.163.com/centos/5/os/x86_64/CentOS/yum-metadata-parser-1.1.2-3.el5.centos.x86_64.rpm
wget http://mirrors.163.com/centos/5/os/x86_64/CentOS/yum-fastestmirror-1.1.16-21.el5.centos.noarch.rpm

也可用此地址：
wget http://centos.ustc.edu.cn/centos/5/os/x86_64/CentOS/python-iniparse-0.2.3-4.el5.noarch.rpm
wget http://centos.ustc.edu.cn/centos/5/os/x86_64/CentOS/yum-3.2.22-39.el5.centos.noarch.rpm
wget http://centos.ustc.edu.cn/centos/5/os/x86_64/CentOS/yum-metadata-parser-1.1.2-3.el5.centos.x86_64.rpm
wget http://centos.ustc.edu.cn/centos/5/os/x86_64/CentOS/yum-fastestmirror-1.1.16-21.el5.centos.noarch.rpm
wget http://sudone.com/download/CentOS-Base.repo -O /etc/yum.repos.d/CentOS-Base.repo

key文件位置可选：
http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-5
http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5
http://mirrors.ustc.edu.cn/centos/RPM-GPG-KEY-CentOS-5

3、安装yum软件包

rpm -ivh --nodeps \
# python-iniparse-0.2.3-4.el5.noarch.rpm \
yum-3.2.22-39.el5.centos.noarch.rpm \
yum-metadata-parser-1.1.2-3.el5.centos.x86_64.rpm \
yum-fastestmirror-1.1.16-21.el5.centos.noarch.rpm

4、添加配置文件

wget http://sudone.com/download/CentOS-Base.repo -O /etc/yum.repos.d/CentOS-Base.repo

5、以防万一，配置文件全文如下

# cat /etc/yum.repos.d/CentOS-Base.repo

6、万事大吉，可以测试了

以下代码为展示，不用敲，只为验证yum是否能连到yum源上。经过下面测试已经可以显示包了，ok。哈哈。配置完成，
