由於紅帽官方的源需要認證，所以需要製作本地的源，今天陳老師給了資料，我們來製作紅帽本地源
需要將將紅帽dvd鏡像拷到本地來
1. mount -o loop rhel-5-server-dvd.iso /media/rhel
2. vi /etc/yum.repos.d/rhel-local.repo
[Cluster]
name=Red Hat =nterprise Linux $releasever - $basearch - Cluster
baseurl=file:///media/rhel/Cluster
enabled=1
gpgchec==1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release
<=R>
[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-=elease
[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
g=gkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release
3. mkdir -p /var/rhel/{Cluster,ClusterStorage,Server,VT}
#這裏你需要下載createrepo的rpm包安裝命令，紅帽安裝時沒有這個命令
4. 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. 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
6. yum clean all
