1 Introduction
As of this writing, the current RHEL release (5) is only available on CDs, not DVD. It is possible to create a bootable DVD ISO from these CDs using Chris Kloiber's mkdvdiso.sh script.
2 Methode 1
2.1 Script mkdvdiso.sh
Insert this in a mkdvdiso.sh file :
#!/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 "" 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 ""
2.2 Install the anaconda-runtime
Prerequisite package and its dependencies :
yum -y install anaconda-run || timerpm -q anaconda-runtime
2.3 Make DVD
Place the CD ISO files and mkdvdiso.sh in a directory, and run the mkdvdiso.sh script.
chmod 755 ./mkdvdiso.sh && ./mkdvdiso.sh
The following command creates a RHEL bootable DVD ISO :
./mkdvdiso.sh . $(pwd)/RedHat-dvd.iso
The file .discinfo should looks like :
1170972069.396645 Red Hat Enterprise Linux Server 5 i386 1,2,3,4,5 Server/base Server/RPMS Server/pixmaps
3 Methode 2
Create folders :
mkdir /mnt/cd{1,2,3,4,5}
Mount every iso images with :
mount -o loop cd1.iso /mnt/cd1
Copy the minimum :
cp -a cd1/isolinux cd1/.discinfo .
Edit the .discinfo and replace 1 with :
1,2,3,4,5
Do this for all your CDs. Then :
mkisofs -o redhat.iso -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table -R -m TRANS.TBL -x \ /mnt/cd1/.discinfo -x /mnt/cd1/isolinux -graft-points /mnt/cd1 .discinfo=.discinfo isolinux/=isolinux RedHat/=/mnt/cd2/RedHat RedHat/=/mnt/cd3/RedHat \ RedHat/=/mnt/cd4/RedHat RedHat/=/mnt/cd5/RedHat
Adapt this for you.
