5.7 6.5 试用：
mkdir /opt/mnt
mount /dev/cdrom /opt/mnt
配置如下 文件：
备份一下原来文件
cp /etc/yum.redo.d/**.repo
/etc/yum.redo.d/**.repo.bak
vim /etc/yum.redo.d/**.repo
添加：
如下既可
在Red Hat Enterprise Linux Server release 5.7 上配置YUM本地源时，
遇到了"Errno 5] OSError: [Errno 2] No such file or directory xxxx",花了点时间搞清楚错误的来龙去脉。特此记录一下：

将Redhat 5.7的光盘镜像拷贝到了/mnt/cdrom/LinuxSrc目录下，配置了rhel-media.repo文件，如下所示
[root@DB-Server yum.repos.d]
# more rhel-media.repo
[media]
name=Red Hat Enterprise Linux 5.7 baseurl= file:///mnt/cdrom/LinuxSrc ; enabled=1
gpgcheck=0
gpgkey= file:///mnt/cdrom/LinuxSrc/RPM-GPG-KEY-redhat-release
[media]
name=Red Hat Enterprise Linux 5.7 baseurl= file:///mnt/cdrom/LinuxSrc ; enabled=1
gpgcheck=0
gpgkey= file:///mnt/cdrom/LinuxSrc/RPM-GPG-KEY-redhat-release
执行yum clean all命令后，执行yum makecache遇到了下面错误：
[root@DB-Server yum.repos.d]
# yum clean allLoaded plugins: product-id, security, subscription-managerUpdating Red Hat repositories.Cleaning up Everything[root@DB-Server yum.repos.d]
# yum makecacheLoaded plugins: product-id, security, subscription-managerUpdating Red Hat repositories.
file:///mnt/cdrom/LinuxSrc/repodata/repomd.xml: [Errno 5] OSError: [Errno 2] No such file or directory:
'/mnt/cdrom/LinuxSrc/repodata/repomd.xml'Trying other mirror.Error: Cannot retrieve repository metadata (repomd.xml)
for repository: media. Please verify its path and try again[root@DB-Server yum.repos.d]#
出现这个错误的根本原因在于RHEL 5.x 版本与RHEL 6.x 版本的rpm包存放路径不同：
RHEL 5.x : ../Server 例如：我案例环境位于/mnt/cdrom/LinuxSrc/Server 下。
RHEL 6.x : ../Packages
所以还在于上面的baseurl参数设置错误。那么我们可以通过两种方法解决这个问题：
方法1：配置正确的baseurl参数。
[root@DB-Server yum.repos.d]
# vi rhel-media.repo
[media]
name=Red Hat Enterprise Linux baseurl=file:///mnt/cdrom/LinuxSrc/Server
enabled=1
gpgcheck=0
gpgkey=file:///mnt/cdrom/LinuxSrc/RPM-GPG-KEY-redhat-release
[media]
name=Red Hat Enterprise Linux baseurl=file:///mnt/cdrom/LinuxSrc/Server
enabled=1
gpgcheck=0
gpgkey=file:///mnt/cdrom/LinuxSrc/RPM-GPG-KEY-redhat-release
方法2：使用createrepo命令创建本地源目录，将其指向baseurl指定的目录
[root@DB-Server Server]
