RedHat Enterprise Linux 6.5使用Centos 6 的yum源

由于redhat6.5的yum功能是需要注册费用的，所以自带的yum并不可用，想要使用免费的yum，可以用Centos6的yum源，配置自己的yum源。具体步骤如下：

（我的机器是32位，所以以下都是基于32位的redhat6.5）

1.先到 http://mirrors.163.com/centos/6/os/i386/Packages/  下载以下软件包：

a.  python-iniparse-0.3.1-2.1.el6.noarch.rpm

b.  yum-3.2.29-40.el6.centos.noarch.rpm

c.  yum-metadata-parser-1.1.2-16.el6.i686.rpm

d.  yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm

下载命令：

a. wget http://mirrors.163.com/centos/6.6/os/i386/Packages/python-iniparse-0.3.1-2.1.el6.noarch.rpm

b. wget http://mirrors.163.com/centos/6.6/os/i386/Packages/yum-3.2.29-40.el6.centos.noarch.rpm

c. wget http://mirrors.163.com/centos/6.6/os/i386/Packages/yum-metadata-parser-1.1.2-16.el6.i686.rpm

d. wget http://mirrors.163.com/centos/6.6/os/i386/Packages/yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm

2、卸载RedHat自带的yum

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

3、安装下载的centos的yum包：

rpm -ivh python-iniparse-0.3.1-2.1.el6.noarch.rpm

rpm -ivh yum-metadata-parser-1.1.2-16.el6.i686.rpm

rpm -ivh   yum-3.2.29-40.el6.centos.noarch.rpm  yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm

[注] :最后2个需要一起安装，否则会出现依赖性错误

4、到 wget http://mirrors.163.com/.help/CentOS6-Base-163.repo 的 centos帮助文档 中下载CentOS6-Base-163.repo文件，去到/etc/yum.repos.d中，有个

rhel-source.repo，先将其备份 为 rhel-source.repo.bak，然后将下载的CentOS6-Base-163.repo拷贝到相同目录下，并改名为 rhel-source.repo

现在开始编辑 rhel-source.repo文件，将里面的$releasever替换为6.6(源里面没有6.5的资源)(我的rhel版本是6.5的，可以通过cat /etc/issue或者cat /etc/redhat-release查看系统版本)

可以用如下命令实现替换

0,$s/$releasever/6.6/g

我的文件内容如下：

# 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.
#

5.yum clean all 清除原有缓存

如果有出先如下提示，则需要先 kill -92267(这个是进程ID，根据以下的提示实际kill进程)，再执行 yum clean all

[root@localhost ~]# yum clean all

6.yum makecache  获取yum列表，会出现如下提示：
