redhat6.5安装yum源

   redhat6.5安装yum源。
   我是按照这篇文章安装的https://www.cnblogs.com/zwgblog/p/5840486.html。在安装过程中报错：
一、

[root@xxzx tmp]# rpm -ivh python-urlgrabber-3.9.1-11.el6.noarch.rpm
warning: python-urlgrabber-3.9.1-11.el6.noarch.rpm: Header V3 RSA/SHA1 Signature, key ID c105b9de: NOKEY

   “file /usr/lib/python2.6/site-packages/urlgrabber/grabber.py from install of python-urlgrabber-3.9.1-11.el6.noarch conflicts with file from package python-urlgrabber-3.9.1-9.el6.noarch”
可以看出报错是由于与历史版本发生冲突。
解决办法：执行以下命令，强制安装。

[root@xxzx tmp]# rpm -ivh --force  python-urlgrabber-3.9.1-11.el6.noarch.rpm

执行结果如下：

warning: python-urlgrabber-3.9.1-11.el6.noarch.rpm: Header V3 RSA/SHA1 Signature, key ID c105b9de: NOKEY
Preparing...                ########################################### [100%]

[root@xxzx tmp]# rpm -ivh yum-3.2.29-81.el6.centos.noarch.rpm yum-plugin-fastestmirror-1.1.30-41.el6.noarch.rpm

   2:yum                    warning: /etc/yum.conf created as /etc/yum.conf.rpmnew
########################################### [100%]

   表明安装成功。
二、执行yum makecache时报错

yum makecache
http://mirrors.163.com/centos/6.5/os/x86_64/repodata/repomd.xml: [Errno 14] PYCURL ERROR 22 - "The requested URL returned error: 404 Not Found"
尝试其他镜像。
To address this issue please refer to the below knowledge base article 

https://access.redhat.com/articles/1320623

If above article doesn't help to resolve this issue please open a ticket with Red Hat Support.

错误：Cannot retrieve repository metadata (repomd.xml) for repository: base. Please verify its path and try again

/etc/*.repo配置文件中的baseurl写错了，应该是baseurl=http://mirrors.163.com/centos/6/os/$basearch/，我写成了baseurl=http://mirrors.163.com/centos/6.5/os/$basearch/。修改之后正确执行，如下：

[root@xxzx yum.repos.d]# yum makecache
