先挂载ISO到某个目录下(如我的：/media/rheliso/)：

# mount –o loop rhel-server-6.4-x86_64-dvd.iso /media/rheliso/ 
# mount –o loop rhel-server-6.4-x86_64-dvd.iso /media/rheliso/


然后编辑rhel-source.repo文件

#vi /etc/yum.repos.d/rhel-source.repo 
#vi /etc/yum.repos.d/rhel-source.repo


加入以下内容(注意对应挂载目录)：

[Server] 
name=rhel5server 
baseurl=file:///media/rheliso/Server 
enable=1 
gpgcheck=1 
gpgkey=file:///media/rheliso/RPM-GPG-KEY-redhat-release 

[Server]
name=rhel5server
baseurl=file:///media/rheliso/Server
enable=1
gpgcheck=1
gpgkey=file:///media/rheliso/RPM-GPG-KEY-redhat-release

注：如果使用下面命令发现如下错误

#yum install eclipse

并且/etc/yum.repos.d/ 目录下有个文件名为'packagekit-media.repo'

请删除之就OK了！！
