Centos 6.3 custom Automatic Installation

Centos 6.3 custom Automatic Installation

I have tried centos5.x before. Today, I saw a friend asking me about the latest custom cd in the Forum. The previous method was unsuccessful. I specifically downloaded a centos 6.3 for testing and recorded the process for sharing. I found that the method is not much different from the previous one. Due to the limited level and environment, this cannot be guaranteed.

 

Test environment: VMware Workstation 8.0 centos 6.3 x86_64
First of all, download a centos 6.3
Centos 6.3:
32-bit: http://mirror.centos.org/centos/6.3/isos/i386/CentOS-6.3-i386-bin-DVD1to2.torrent
64-bit: http://mirror.centos.org/centos/6.3/isos/x86_64/CentOS-6.3-x86_64-bin-DVD1to2.torrent

When installing the system, select the required software package for minimal installation. The installation process is similar to that of the previous version. skip this step and start the following steps:

 

1. Install the required software package:
[Root @ localhost ~] # Yum-y install createrepo mkisofs isomd5sum

 

2. Generate the RPM list required for installing the System Based on the software packages already installed in the current system
[Root @ localhost ~] # Awk '/installing/{print $2}' install. log | SED's/^ [0-9] *: // G'>/root/packages. List

 

3. Create a customized directory and copy files other than the packages directory to the new system directory.
[Root @ localhost ~] # Mkdir/mnt/CDROM
[Root @ localhost ~] # Mkdir-P/data/OS
[Root @ localhost ~] # Mount/dev/CDROM/mnt/CDROM/
[Root @ localhost ~] # Rsync-A -- exclude = packages/mnt/CDROM/data/OS/
[Root @ localhost ~] # Mkdir/data/OS/Packages

 

4. Use the script to automatically copy the required RPM package to the new CD directory packages
[Root @ localhost ~] # Vim cprpms. Sh

1.
#! /Bin/bash

2.
Src_rpms =/mnt/CDROM/Packages

3.
Dst_rpms =/data/OS/Packages

4.
Packages_list =/root/packages. List

5.
Number_of_packages = 'cat $ packages_list | WC-l'

6.
I = 1

7.
While [$ I-Le $ number_of_packages];

8.
Do

9.
Name = 'head-N $ I $ packages_list | tail-n-1'

10.
Echo "CP $ src_rpms/$ name * $ dst_rpms /"

11.
CP $ src_rpms/$ name * $ dst_rpms/

12.
I = 'expr $ I + 1'

13.
Done

[Root @ localhost ~] # Sh cprpms. Sh

 

5. Configure the Kickstart script
[Root @ localhost ~] # Vim/data/OS/isolinux/KS. cfg

6. enable the system to start installation from kickstart Configuration
[Root @ localhost OS] # Vim/data/OS/isolinux. cfg
Default Linux
Label Linux
Kernel vmlinuz
Append Ks = CDROM:/isolinux/KS. cfg initrd = initrd. IMG # modify the line

 

7. Generate the dependency of the RPM package
[Root @ localhost ~] # Cd/data/OS/
[Root @ localhost OS] # createrepo-G repodata/*-comps. xml/data/OS/
[Root @ localhost OS] # declare-x discinfo = 'head-1. discinfo'
[Root @ localhost OS] # createrepo-U "Media: // $ discinfo"-G repodata/*-comps. xml/data/OS/

 

8. generate an ISO Image File
[Root @ localhost ~] # Cd/data/OS/
[Root @ localhost OS] # mkisofs-r-J-t-r-l-D-Joliet-Long-allow-multidot \
-Allow-leading-dots-no-Bak-O/data/CentOS-6.3-x86_64.iso \
-B isolinux/isolinux. Bin-C isolinux/boot. Cat-no-emul-boot \
-Boot-load-size 4-boot-Info-table/data/OS

 

9. generate an MD5 Verification Code
[Root @ localhost ~] # Implantisomd5/data/CentOS-6.3-x86_64.iso
