1、建立以下文件夹

[david@haibinpark ~]$ sudo mkdir /media/dvd
[sudo] password for david:
[david@haibinpark ~]$ sudo mkdir /media/repo/fedora -p
[david@haibinpark ~]$ sudo mkdir /media/repo/repodata
[david@haibinpark ~]$

2、挂载DVD ISO镜像

[david@haibinpark ~]$ sudo mount -r -o loop Fedora-15-i386-DVD.iso /media/dvd/
[david@haibinpark ~]$ sudo mount –bind /media/dvd/Packages/ /media/repo/fedora/
mount: warning: /media/repo/fedora/ seems to be mounted read-only.
[david@haibinpark ~]$

3、拷贝文件到指定目录

[david@haibinpark ~]$ sudo cp /media/dvd/repodata/repomd.xml /media/repo/repodata/ -p

4、创建安装源

[david@haibinpark ~]$ cd /media/repo/
[david@haibinpark repo]$ ls
fedora  repodata
[david@haibinpark repo]$ sudo createrepo -g repodata/repomd.xml .

[david@haibinpark yum.repos.d]$ touch iso.repo
[david@haibinpark yum.repos.d]$ ls
iso.repo
[david@haibinpark yum.repos.d]$ cat iso.repo
[dvd-repo]
