最近找RedHat Linux5.0 x86_64的DVD ISO文件，结果一直找不到，却找到了6个cd的ISO，因为最后一个为源码盘，暂时不管，把其他5个CD合并成一个DVD。

脚本如下：

vim dvd.sh

#!/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 ""

把5个iso放到/u01下

执行一下命令

./dvd.sh /u01 /u01/redhat5.0_x86_64_dvd.iso

结果如下：

Total translation table size: 710166

Total rockridge attributes bytes: 306908

在linux下进行挂载ISO

mount -o loop -t iso9660 redhat5.0_x86_64_dvd.iso /media
