1、建立以下文件夾
[www.linuxidc.com@linuxidc ~]$ sudo mkdir /media/dvd
[sudo] password for david:
[www.linuxidc.com@linuxidc ~]$ sudo mkdir /media/repo/Fedora -p
[www.linuxidc.com@linuxidc ~]$ sudo mkdir /media/repo/repodata
[www.linuxidc.com@linuxidc ~]$
2、掛載DVD ISO鏡像
[www.linuxidc.com@linuxidc ~]$ sudo mount -r -o loop Fedora-15-i386-DVD.iso /media/dvd/
[www.linuxidc.com@linuxidc ~]$ sudo mount –bind /media/dvd/Packages/ /media/repo/fedora/
mount: warning: /media/repo/fedora/ seems to be mounted read-only.
[www.linuxidc.com@linuxidc ~]$
3、拷貝文件到指定目錄
[www.linuxidc.com@linuxidc ~]$ sudo cp /media/dvd/repodata/repomd.xml /media/repo/repodata/ -p
4、創建安裝源
[www.linuxidc.com@linuxidc ~]$ cd /media/repo/
[www.linuxidc.com@linuxidc repo]$ ls
fedora repodata
[www.linuxidc.com@linuxidc repo]$ sudo createrepo -g repodata/repomd.xml .

[www.linuxidc.com@linuxidc repo]$ cd /etc/yum.repos.d/
[www.linuxidc.com@linuxidc yum.repos.d]$ touch iso.repo
[www.linuxidc.com@linuxidc yum.repos.d]$ ls
iso.repo
[www.linuxidc.com@linuxidc yum.repos.d]$ cat iso.repo
[dvd-repo]
