rhel5之光盘更新终结篇

1，进入/etc/yum.repos.d目录中，编辑rhel5-local.repo文件，这个文件名可以随便取，以个人爱好为准，加入如下内容：
[Cluster]
name=Red Hat Enterprise Linux $releasever - $basearch -Cluster
baseurl=file:///mnt/rhel5/Cluster
enable=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:///mnt/rhel5/ClusterStorage
enable=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:///mnt/rhel5/Server
enable=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:///mnt/rhel5/VT
enable=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release
2，挂载你的rhel5.iso文件.
   mount /dev/hdc /mnt/rhel5
我是在vmware里做的，它的光驱就是/dev/hdc设备。
3，创建以下几个必要的目录：
mkdir -p /var/rhel/{Cluster,ClusterStorage,Server,VT}
4，用createrepo命令创建相应文件，前提你必须安装createrepo软件包：
createrepo -o /var/rhel/Cluster -g      /mnt/rhel5/Cluster/repodata/comps-rhel5-cluster.xml  /mnt/rhel5/Cluster
createrepo -o /var/rhel/ClusterStorage -g      /mnt/rhel5/ClusterStorage/repodata/comps-rhel5-cluster-st.xml    /mnt/rhel5/ClusterStorage
createrepo -o /var/rhel/Server -g   /mnt/rhel5/Server/repodata/comps-rhel5-server-core.xml  /mnt/rhel5/Server
createrepo -o /var/rhel/VT -g  /mnt/rhel5/VT/repodata/comps-rhel5-VT.xml     /mnt/rhel5/VT
5，挂载：
mount --bind  /var/rhel/Cluster/repodata  /mnt/rhel5/Cluster/repodata
mount --bind  /var/rhel/ClusterStorage/repodata  /mnt/rhel5/ClusterStorage/repodata
mount --bind  /var/rhel/Server/repodata  /mnt/rhel5/Server/repodata
mount --bind  /var/rhel/VT/repodata  /mnt/rhel5/VT/repodata
6，yum clean all
剩下的就是安装软件包和更新了，呵呵，自己试试吧！ 现在的rhel5.3版本不用这么麻烦了。比如，光盘挂载的目录是/misc/cd，则在/etc/yum.repos.d目录中创建rhel5.repo文件。这个文件的名字随便叫，格式如下：[Cluster]
name=Red Hat Enterprise Linux $releasever - $basearch -Cluster
baseurl=file:///misc/cd/Cluster
enable=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:///misc/cd/ClusterStorage
enable=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:///misc/cd/Server
enable=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:///misc/cd/VT
enable=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release
完了，你就可以yum update、install and so on.
