centos yum时总出错

yum错误：

*
c5-media:

file:///media/CentOS/repodata/repomd.xml: [Errno 5] OSError: [Errno 2] 没有那个文件或目录: '/media/CentOS/repodata/repomd.xml'

file:///media/cdrom/repodata/repomd.xml: [Errno 5] OSError: [Errno 2] 没有那个文件或目录: '/media/cdrom/repodata/repomd.xml'

Trying other mirror.

Error: Cannot retrieve repository metadata (repomd.xml) for repository: c5-media. Please verify its path and try again

CentOS 5.2光盘安装后，安装Yum，配置/etc/yum.repos.d/CentOS-Base.repo文件，

然后执行yum install ***

总是出现下列错误

file://media/CentOS_5.2_Final/repodata/repomd.xml:[Error 5] OSError：［Errno 2］

Trying other mirror.

Error: Cannot retrieve repository metadata(repomd.xml) for repository: c5-media.

Please verify its path and try again

问题原因：/etc/yum.repos.d目录下配置文件

CentOS-Media.repo文件影响Yum访问源

解决方法：将CentOS-Media.repo文件删除

重试yum install ***

正常了。

附配置文件/etc/yum.repos.d/CentOS-Base.repo全文
