1 将5张以CD合成一长DVD

touch /root/make_dvd.sh

内容如下

#!/bin/bash

# by Chris Kloiber

# 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 ""

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

echo " set of isos, or an exploded tree like an ftp site."

exit 1

fi

cleanup() {

[ ${LOOP:=/tmp/loop} = "/" ] && echo "LOOP mount point = \/, dying!" && exit

[ -d $LOOP ] && rm -rf $LOOP

[ ${DVD:=~/mkrhdvd} = "/" ] && echo "DVD data location is \/, dying!" && exit

[ -d $DVD ] && rm -rf $DVD

}

cleanup

mkdir -p $LOOP

mkdir -p $DVD

if [ !`ls $1/*.iso 2>&1>/dev/null ; echo $?` ]; then

echo "Found ISO CD images..."

CDS=`expr 0`

DISKS="1"

for f in `ls $1/*.iso`; do

mount -o loop $f $LOOP

cp -av $LOOP/* $DVD

if [ -f $LOOP/.discinfo ]; then

cp -av $LOOP/.discinfo $DVD

CDS=`expr $CDS + 1`

if [ $CDS != 1 ] ; then

DISKS=`echo ${DISKS},${CDS}`

fi

fi

umount $LOOP

done

if [ -e $DVD/.discinfo ]; then

awk '{ if ( NR == 4 ) { print disks } else { print ; } }' disks="$DISKS" $DVD/.discinfo > $DVD/.discinfo.new

mv $DVD/.discinfo.new $DVD/.discinfo

fi

else

echo "Found FTP-like tree..."

cp -av $1/* $DVD

[ -e $1/.discinfo ] && cp -av $1/.discinfo $DVD

fi

rm -rf $DVD/isolinux/boot.cat

find $DVD -name TRANS.TBL | xargs rm -f

cd $DVD

mkisofs -J -R -v -T -o $2 -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table .

/usr/lib/anaconda-runtime/implantisomd5 --force $2

cleanup

echo ""

echo "Process Complete!"

echo ""

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
