1 将5张以CD合成一长DVD

#!/bin/bash

# by Chris Kloiber <ckloiber@redhat.com>

# A quick hack that will create a bootable DVD iso of a Red Hat Linux
# Distribution. Feed it either a directory containing the downloaded
# iso files of a distribution, or point it at a directory containing
# the "RedHat", "isolinux", and "images" directories.

# This version only works with "isolinux" based Red Hat Linux versions.

# Lots of disk space required to work, 3X the distribution size at least.

# GPL version 2 applies. No warranties, yadda, yadda. Have fun.


if [ $# -lt 2 ]; then
        echo "Usage: `basename $0` source /destination/DVD.iso"

        echo "        The 'source' can be either a directory containing a single"

cd $DVD

cleanup

3 cd /root
chmod a+x make_dvd.sh
假设我的5张cd在
/wind/redhat/rhel-5-server-i386-disc1.iso
/wind/redhat/rhel-5-server-i386-disc2.iso
/wind/redhat/rhel-5-server-i386-disc3.iso
/wind/redhat/rhel-5-server-i386-disc4.iso
/wind/redhat/rhel-5-server-i386-disc5.iso
./make_dvd.sh /wind/redhat /mydoc/rhel-5-server-i386-DVD.iso
然后在/mydoc目录下产生rhel-5-server-i386-DVD.iso
5 mkdir /rhel_dvd
mount -o loop /mydoc/rhel-5-server-i386-DVD.iso /rhel_dvd
6gedit /etc/yum.repos.d/rhel_local.repo
内容如下:
[Cluster]
name=Red Hat Enterprise Linux $releasever-$basearch-Cluster
baseurl=file:///rhel_dvd/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:///rhel_dvd/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:///rhel_dvd/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:///rhel_dvd/VT
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release

7执行createrepo命令，如果找不到命令，则要先安装createrepo的rpm包，自己google吧
为了方便，创建一个sh文件
touch /root/yum.sh
内容如下:
mkdir -p /var/rhel/{Server,Cluster,ClusterStorage,VT}
createrepo -o /var/rhel/Cluster -g /rhel_dvd/Cluster/repodata/comps-rhel5-cluster.xml /rhel_dvd/Cluster
createrepo -o /var/rhel/ClusterStorage -g /rhel_dvd/ClusterStorage/repodata/comps-rhel5-cluster-st.xml /rhel_dvd/ClusterStorage
createrepo -o /var/rhel/Server -g /rhel_dvd/Server/repodata/comps-rhel5-server-core.xml /rhel_dvd/Server
createrepo -o /var/rhel/VT -g /rhel_dvd/VT/repodata/comps-rhel5-vt.xml /rhel_dvd/VT
mount --bind /var/rhel/Cluster/repodata /rhel_dvd/Cluster/repodata
mount --bind /var/rhel/ClusterStorage/repodata /rhel_dvd/ClusterStorage/repodata
mount --bind /var/rhel/Server/repodata /rhel_dvd/Server/repodata
mount --bind /var/rhel/VT/repodata /rhel_dvd/VT/repodata
yum clean all
chmod a+x yum.sh
./yum.sh
完成
