yum加载本地iso文件源

mkdir /mnt/fc6
mount -t iso9660 -o loop /mnt/WinJ/FC-6-i386-DVD.iso /mnt/fc6
touch /etc/yum.repo.d/iso.repo

gedit/vi iso.repo 写入如下内容：
［ISO]
name = ISO Fedora Core $releasever - $basearch - released updates
baseurl = file:///mnt/fc6
gpgkey = file:///mnt/fc6/ROM-GPG-KEY-fedora file:///mnt/fc6/RPM-GPG-KEY
failovermethod = priority
enabled = 1
gpgcheck = 0

再把yum正常的源关掉。
gedit/vi fedora-core.repo
