redhat 6.8 配置centos6的yum源

1. 检查是否安装yum包
[root@node1 rpms]# rpm -qa|grep yum

2. 删除自带的yum包
[root@node1 rpms]# rpm -qa|grep yum|xargs rpm -e --nodeps
因为一些包之间可能会有依赖关系，所以我们需要加上参数 --nodeps 无视依赖关系。

3. 下载yum包
Yum包下载地址http://mirrors.163.com/centos/
在这个网站里，你可以自己选择需要下载的文件，进入形如5/或者6/的文件下载，其他的无法下载。

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-3.2.29-73.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-1.1.30-37.el6.noarch.rpm

4. 安装yum包
[root@node1 rpms]# rpm -ivh python-iniparse-0.3.1-2.1.el6.noarch.rpm
[root@node1 rpms]# rpm -ivh yum-metadata-parser-1.1.2-16.el6.x86_64.rpm
[root@node1 rpms]# rpm -ivh yum-3.2.29-73.el6.centos.noarch.rpm yum-plugin-fastestmirror-1.1.30-37.el6.noarch.rpm

或者用以下命令
rpm -ivh yum-metadata-parser-1.1.2-16.el6.x86_64.rpm yum-3.2.29-73.el6.centos.noarch.rpm yum-plugin-fastestmirror-1.1.30-37.el6.noarch.rpm --force --nodeps

5. 替换yum源

[root@node2 /]# cd /etc/yum.repos.d/
[root@node2 yum.repos.d]# cat CentOS6-Base-163.repo
# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client. You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.
#

[base]

gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6

如果wget http://mirrors.163.com/.help/CentOS6-Base-163.repo　下载的，需要修改下里面的变量。

6. 清除缓存：
[root@node2 /]# yum clean all

7. 加载缓存：
[root@node2 /]# yum makecache

8. 更新软件：
[root@node2 /]# yum update

以上方法也是Red Hat Enterprise Linux Server(RHEL) yum安装软件时This system is not registered with RHN. RHN support will be disabled. 的解决方法
Red Hat Enterprise Linux Server(RHEL) 的yum服务是付费的，因为没有付费，所以无法使用yum安装软件，如RHEL想安装LNMP必须要先按此教程设置好yum，并可以正常使用后才可以安装LNMP一键安装包，会提示如下错误：This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register. 或如下错误信息：This system is not registered with RHN. RHN support will be disabled.
