redhat默认不支持第三方的yum源，要求有rhn账号，下面就rhel5和rhel6改为centos源
一、rhel5.5 X86_64更改为centos的yum源
查看系统自带的yum相关的rpm包
rpm -qa|grep yum
删掉系统自带的yum相关的包
rpm -e --nodeps yum-updatesd-0 rpm -e --nodeps yum-security rpm -e --nodeps yum-metadata-p rpm -e --nodeps yum-rhn-plugin
安装163yum包,三个yum包有依赖关系，需要一起安装
wget http://mirrors.163.com/centos/5/os/x86_64/CentOS/python-iniparse-0.2.3-6.el5.noarch.rpm wget http://mirrors.163.com/centos/5/os/x86_64/CentOS/yum-fastestmirror-1.1.16-21.el5.centos.noarch.rpm wget wget rpm -ivh python-iniparse-0.2.3-6.el5.noarch.rpm rpm -ivh yum-fastestmirror-1.1.16-21.el5.centos.noarch.rpm yum-3.2.22-40.el5.centos.noarch.rpm yum-metadata-parser-1.1.2-4.el5.x86_64.rpm
在/etc/yum.repos.d下将原有的repo文件重命名，新建一个Base.repo
[base] name=Red Hat Enterprise Linux $releasever - Base baseurl=http://mirror.centos.org/centos/5/os/$basearch/ gpgcheck=1 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5 #released updates [updates] name=Red Hat Enterprise Linux $releasever - Updates baseurl=http://mirror.centos.org/centos/5/updates/$basearch/ gpgcheck=1 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5 #packages used/produced in the build but not released [addons] name=Red Hat Enterprise Linux $releasever - Addons baseurl=http://mirror.centos.org/centos/5/addons/$basearch/ pgcheck=1 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5 #additional packages that may be useful [extras] name=Red Hat Enterprise Linux $releasever - Extras baseurl=http://mirror.centos.org/centos/5/extras/$basearch/ gpgcheck=1 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5 #additional packages that extend functionality of existing packages [centosplus] name=Red Hat Enterprise Linux $releasever - Plus baseurl=http://mirror.centos.org/centos/5/centosplus/$basearch/ gpgcheck=1 enabled=0 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5 #contrib - packages by Centos Users [contrib] name=Red Hat Enterprise Linux $releasever - Contrib baseurl=http://mirror.centos.org/centos/5/contrib/$basearch/ gpgcheck=1 enabled=0 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5
这里也可以使用mirrors.163.com或者mirrors.aliyun.com的yum源， rhel6则以163yum源为例，导入key
rpm --import http://mirror.centos.org/centos/5/os/x86_64/RPM-GPG-KEY-CentOS-5
生成缓存
yum clean all yum makecache
如果配置成功则会提示加载成功
二、redhat6.4 X86_64更改为centos的yum源
删除原有的yum相关的rpm包
rpm -qa|grep yum rpm -e --nodeps yum-rhn-plugin rpm -e --nodeps yum-metadata-parser rpm -e --nodeps yum-utils rpm -e --nodeps yum-plugin-security rpm -e --nodeps rhn-check
下载安装包并安装
mkdir -p /server/tools cd /server/tools/ wget http://mirrors.163.com/centos/6/os/x86_64/Packages/python-iniparse-0.3.1-2.1.el6.noarch.rpm wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-3.2.29-69.el6.centos.noarch.rpm wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-metadata-parser-1.1.2-16.el6.x86_64.rpm wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.30-30.el6.noarch.rpm rpm -ivh python-iniparse-0.3.1-2.1.el6.noarch.rpm rpm -ivh yum-3.2.29-69.el6.centos.noarch.rpm yum-metadata-parser-1.1.2-16.el6.x86_64.rpm yum-plugin-fastestmirror-1.1.30-30.el6.noarch.rpm
重命名原有自带的repo文件，并下载163的repo文件
cd /etc/yum.repos.d/ mv rhel-source.repo rhel-source.repo.bak wget http://mirrors.163.com/.help/CentOS6-Base-163.repo rpm --import http://mirrors.163.com/centos/6/os/x86_64/RPM-GPG-KEY-CentOS-6 sed -i ‘s#$releasever#6#g‘ CentOS6-Base-163.repo
清空缓存，并重新生成
yum clean all yum makecache
如果配置阿里的yum源，则可以加入如下命令
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo
至此rhel6配置centos源配置完成
