1. download the complete DVD from www.centos.org.

2. first, you need to customize the installation, and then install/root/install from the secure system. log to generate the list of software you want to install. run the following command:

Cat/root/install. log | grep Installing | sed's/Installing // g' | sed's/^ [0-9] \ +: // g'>/tmp/rpm. log

Create a directory for storing rpm packages mkdir-p/data/cdrom/CentOS

Mount the ISO of CenOS55 to mount-o loop CentOS-5.5-i386-bin-DVD.iso/mnt under/mnt

Put the software in rpm. log in a directory and use the rpm. sh file.

#! /Bin/bash

DEBUG = 0

LT_CD =/mnt

ALL_RPMS_DIR =/mnt/CentOS

LT_RPMS_DIR =/data/cdrom/CentOS

Packages_list =/tmp/rpm. log

Number_of_packages = 'cat $ packages_list | wc-L'

I = 1

While [$ I-le $ number_of_packages]; do

Line = 'head-n $ I $ packages_list | tail-n-1'

Name = 'echo $ line | awk' {print $1 }''

Version = 'echo $ line | awk' {print $3} '| cut-f 2-d :'

If [$ DEBUG-eq "1"]; then

Echo $ I: $ line

Echo $ name

Echo $ version

Fi

If [$ DEBUG-eq "1"]; then

Ls $ ALL_RPMS_DIR/$ name-$ version *

If [$? -Ne 0]; then

Echo "cp $ ALL_RPMS_DIR/$ name-$ version *"

Fi

Else

Echo "cp $ ALL_RPMS_DIR/$ name-$ version * $ LT_RPMS_DIR /"

Cp $ ALL_RPMS_DIR/$ name-$ version * $ LT_RPMS_DIR/

# In case the copy failed

If [$? -Ne 0]; then

Echo "cp $ ALL_RPMS_DIR/$ name-$ version *"

Cp $ ALL_RPMS_DIR/$ name * $ LT_RPMS_DIR/

Fi

Fi

I = 'expr $ I + 1'

 

Done

 

Execute sh rpm. sh

You can copy the required package to/data/cdrom/CentOS.

Copy other CD files to/data/cdrom/CenOS

Run rsync-avpz-exclude = "CenOS"/mnt/*/data/cdrom/

Note that you do not need to use the cp command because the cp command does not copy the files starting with "." and No. discinfo. treeinfo in the ISO file. the CD cannot be used. remember! It took me one morning to discover this problem.

 

3. update the structure of the CD software package

Cd/data/cdrom/CentOS

Createrepo-g ../repodata/comps. xml.

 

4. set it to automatic installation mode

Modify the/data/cdrom/CentOS/isolinux. cfg file as follows:

Cat/data/cdrom/CentOS/isolinux. cfg

Default linux

Display boot. msg

F1 boot. msg

F2 options. msg

F3 general. msg

F4 param. msg

F5 rescue. msg

Label linux

Kernel vmlinuz

Append initrd = initrd. img ramdisk_size = 8192 ks = cdrom:/ks. cfg

Label text

Kernel vmlinuz

Append initrd = initrd. img text

Label ks

Kernel vmlinuz

Append ks initrd = initrd. img

Label local

Localboot 1

Label memtest86

Kernel memtest

Append-

 

5. Generate the ks. cfg file

Cat/data/cdrom/CentOS/ks. cfg

Install

6. generate ISO and put this ISO under/data

Mkisofs-r-T-J-V "CentOS"-B isolinux/isolinux. bin-c isolinux/boot. cat-no-emul-boot-load-size 4-boot-info-table-o/data/CentOS5.5-i386.iso/data/cdrom/
