RedHat Enterprise Linux 6.4使用Centos 6 的yum源

思路：卸载redhat自带yum，然后下载centos的yum，安装后修改配置文件

1、首先到http://mirrors.163.com/centos下载软件包

<wbr></wbr>

x86 地址：http://mirrors.163.com/centos/6/os/i386/Packages/

x86_64 地址：http://mirrors.163.com/centos/6/os/x86_64/Packages/

必要下载的软件包有（以64位系统为例）：

a<wbr>python-iniparse-0.3.1-2.1.el6.noarch.rpm</wbr>

b<wbr>yum-3.2.29-40.el6.centos.noarch.rpm</wbr>

c<wbr>yum-metadata-parser-1.1.2-16.el6.x86_64.rpm</wbr>

d<wbr>yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm</wbr>

下载命令：

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-metadata-parser-1.1.2-16.el6.x86_64.rpm

wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-3.2.29-40.el6.centos.noarch.rpm

wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm

[注] :版本不一定要最新的

2、卸载RedHat自带的yum

<wbr></wbr>

<wbr><wbr><wbr><wbr><wbr>rpm -qa | grep yum | xargs rpm -e --nodeps</wbr></wbr></wbr></wbr></wbr>

<wbr><wbr><wbr><wbr><wbr><wbr>注：a、xargs是一条<a target="_blank" href="http://baike.baidu.com/view/8095.htm" style="text-decoration:none; color:rgb(49,139,146)">Unix</a>和类Unix操作系统的常用命令。它的作用是将参数列表转换成小块分段传递给其他命令，以避免参数列表过长的问题</wbr></wbr></wbr></wbr></wbr></wbr>

<wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr>b、--nodeps<wbr>强制卸载,不管依赖性</wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr>

<wbr></wbr>

3、安装下载的centos的yum包：

<wbr></wbr>

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

<wbr></wbr>

[注] :最后2个需要一起安装，否则会出现依赖性错误

<wbr></wbr>

4、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

<wbr></wbr>

wget http://mirrors.163.com/.help/CentOS6-Base-163.repo

5、编辑CentOS6-Base-163.repo文件，将其中的$releasever更改为centos的版本号

下面是修改好的：

# 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.<wbr>You should use this for CentOS updates</wbr>

# 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.

#

#

<wbr></wbr>

6、yum clean all清除原有缓存

7、yum makecache<wbr>获取yum列表</wbr>

出现下面提示，表示yum更改完成：
