使企业版redhat5.2
使用yum安装时出现的如下错误，请各位帮我解决一下。
[root@localhost ~]# yum install mysql
Loading "rhnplugin" plugin

RHN support will be disabled.
file:///mnt/repodata/repomd.xml: [Errno 5] OSError: [Errno 2] No such file or directory: '/mnt/repodata/repomd.xml'
Trying other mirror.
Error: Cannot retrieve repository metadata (repomd.xml) for repository: rhel-debuginfo. Please verify its path and try again

check /etc/yum.repos.d/ file.
there should be a file containing 'rhel-debuginfo' remove that file or change the 'baseurl' to correct one.

also if you don't have RHN register, (got from 'This system is not registered with RHN. '), basically you can not get any rpm repository other than those coming with the RHEL DVD iso.

载入“rhnplugin”插件
载入中“安全”插件
该系统是在RHN没有登记。
红帽网络支持将被禁用。

1、你的yum没有正确配置
2、没有注册
3、建议使用centos的yum源
4、建议使用rpmfprge的yum源
