本文介绍了解决CentOS系统中使用163 yum源配置时遇到的404错误的方法，通过调整配置文件中的变量使源正确解析。

首先说下yum源，使用的是163的源。http://mirrors.163.com/.help/CentOS6-Base-163.repo

[base]

name=CentOS-$releasever - Base - 163.com

baseurl=http://mirrors.163.com/centos/$releasever/os/$basearch/

#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os

gpgcheck=1

gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6

配置好以后，直接yum clean all，没什么问题，接下来yum makecache的时候报错就出来了。

 
        http://mirror.centos.org/centos/%24releasever/os/i386/repodata/repomd.xml: [Errno 14] PYCURL ERROR 22 - "The requested URL returned error: 404"
       
        Trying other mirror.
       
        Error: Cannot retrieve repository metadata (repomd.xml) for repository: base. Please verify its path and try again

网上说是因为DNS的问题，好吧，试了一下，没用啊，DNS改完也不行，ping源地址还是没问题，wget也没问题。再看看报错吧！http://mirror.centos.org/centos/%24releasever/os/i386/repodata/repomd.xml这个地址怎么成这样了呢？%24是神马东东，复制地址，到浏览器，果然是404错误，正常的源地址肯定不是这个，那么看一下配置文件吧，baseurl=http://mirrors.163.com/centos/$releasever/os/$basearch/

$releaserver这个应该是系统的版本，那么我们看一下这个变量能不能解释吧，

 
        [root@aaa ~]# echo $releasever
       
        [root@aaa ~]#

好吧，发现问题了吧，这个变量不能解释啊，试试将它换成网站上的6，看能不能行呢。

[base]

name=CentOS-$releasever - Base - 163.com

#baseurl=http://mirrors.163.com/centos/$releasever/os/$basearch/

baseurl=http://mirrors.163.com/centos/6/os/i386/

#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os

gpgcheck=1

gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6

修改完毕，重新试一下，果然没问题了

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

安装个软件试一下呢？

 
        [root@aaa yum.repos.d]# yum install lrzsz -y
