RedHat6配置CentOS6的yum源方法

相关资源：

163镜像地址：http://mirrors.163.com/

CentOS32位系统相关包地址：http://mirrors.163.com/centos/6/os/i386/Packages/

CentOS64位系统相关包地址：http://mirrors.163.com/centos/6/os/x86_64/Packages/

具体步骤：

1、下载相关包：

必须的包(这里我用的是64位系统)：

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

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

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

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

下载命令如下[建议切换到/opt 目录下执行命令，因为下载操作将现在文件到当前所在目录]：

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-3.2.29-40.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-1.1.30-14.el6.noarch.rpm
[PS：可根据自行需要选择相关版本]

2、卸载RedHat自带的yum

卸载命令如下：

rpm -qa | grep yum | xargs rpm -e --nodeps
PS：
xargs是一条Unix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
--nodeps  强制卸载,不管依赖性

3、安装第1步已下载的文件包

安装命令会在当前所以目录寻找文件，所以需保证已切换到/opt 目录下，执行下列命令安装相关文件包

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

4、下载CentOS的帮助文件到/etc/yum.repo.d中：

帮助文件的163镜像地址根目录为：http://mirrors.163.com/.help/

切换到/etc/yum.repo.d目录下，运行下列命令下载CentOS6-Base-163.repo文件：

wget http://mirrors.163.com/.help/CentOS6-Base-163.repo
5、编辑CentOS6-Base-163.repo文件，将其中的$releasever全部替换为CentOS的版本号，此处我设置为6
修改完成后的文件如下：

# 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.
#
#

6、清除原有缓存
yum clean all

7、获取yum列表
yum makecache[PS:成功后会看到"Metadata Cache Created"消息提示]
