RedHat Enterprise Linux 6.4 使用 CentOS6 的yum源问题

yes-no

#yum install pam-devel
#This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.
Setting up Install Process
Nothing to do
    经过一个上午的研究发现，其实如果使用redhat的yum源需注册付费，费时费力，只在自己电脑上搭了个redhat系统而已，没必要为此大费周章。通过度娘发现了很多解决办法，但很多办法在我电脑上行不通，才知道广大网友的环境是不一样的，所以他们的办法不一定符合自己的电脑。
下面是笔者结合网上的相关资料，针对与我相同环境的系统的解决办法。
系统：RedHat Enterprise Linux 6.4-x86_64 md5:467B53791903F9A0C477CBB1B24FFD1F   这是下载地址：http://pan.baidu.com/s/1bniVAMj
第一步下载相关安装包
可以通过http://mirrors.163.com/centos下载，这是笔者已经下载好的http://pan.baidu.com/s/1qW0MbgC
第二步卸载Redhat自带的yum
#rpm -qa | grep yum | xargs rpm -e --nodeps
第三步安装下载的安装包
#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
第四步到http://mirrors.163.com的 centos帮助文档
中下载CentOS6-Base-163.repo文件，存放到/etc/yum.repo.d中
#wget http://mirrors.163.com/.help/CentOS6-Base-163.repo
第五步将Centos6-Base-163.repo中的$releasever改为Centos的版本号即可
为了防止错误，也可使用我已修改好的文件http://pan.baidu.com/s/1o6AZ23o
文件修改成如下即可：
# 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.

第六步 yum clean all 清除原有缓存
第七步 yum makecache  获取yum列表
等待，大约三分钟后出现下面提示，表示yum更改完成：
