RHEL5 使用 ISO 文件作为 YUM 源

1. 设置 iso 文件的自动挂载并安装 createrepo
mkdir /media/rhel
mount -o loop rhel-5-server-i386-dvd.iso /media/rhel
vi /etc/fstab
/dev/cdrom /media/rhel iso9660 ro 0 0
mount -a
rpm -ivh /media/rhel/Server/createrepo-0.4.11-3.el5.noarch.rpm

2. 配置 repo
cd /etc/yum.repos.d
mv rhel-debuginfo.repo rhel-debuginfo.repo~
vi rhel-media.repo

[Cluster]
name=Red Hat Enterprise Linux $releasever - $basearch - Cluster
baseurl=file:///media/rhel/Cluster
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release

[ClusterStorage]
name=Red Hat Enterprise Linux $releasever - $basearch - ClusterStorage
baseurl=file:///media/rhel/ClusterStorage
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release

[Server]
name=Red Hat Enterprise Linux $releasever - $basearch - Server
baseurl=file:///media/rhel/Server
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release

[VT]
name=Red Hat Enterprise Linux $releasever - $basearch - VT
baseurl=file:///media/rhel/VT
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release

3. 创建所需目录
mkdir -p /var/rhel/{Cluster,ClusterStorage,Server,VT}

4. createrepo:
createrepo -o /var/rhel/Cluster -g /media/rhel/Cluster/repodata/comps-rhel5-cluster.xml /media/rhel/Cluster
createrepo -o /var/rhel/ClusterStorage -g /media/rhel/ClusterStorage/repodata/comps-rhel5-cluster-st.xml /media/rhel/ClusterStorage
createrepo -o /var/rhel/Server -g /media/rhel/Server/repodata/comps-rhel5-server-core.xml /media/rhel/Server
createrepo -o /var/rhel/VT -g /media/rhel/VT/repodata/comps-rhel5-vt.xml /media/rhel/VT

5. 避免无谓的“下载”
mount --bind /var/rhel/Cluster/repodata /media/rhel/Cluster/repodata
mount --bind /var/rhel/ClusterStorage/repodata /media/rhel/ClusterStorage/repodata
mount --bind /var/rhel/Server/repodata /media/rhel/Server/repodata
mount --bind /var/rhel/VT/repodata /media/rhel/VT/repodata

可加入 /etc/rc.local 开机自动绑定。

6. 清除缓存
yum clean all
