1、安装一个干净的操作系统.包括基本的系统和所需要的工具等.

比如:对于http,mysql等软件,建议使用编译的方式安装, 然后打包放进去,可以减少许多依赖包的麻烦.

2、安装系统后,收集系统已安装的软件包,使用脚本统一转存到一个目录中.

3、在安装光盘复制images镜像,从光盘启动centos安装所需的文件等.

4、定义自己的kickstart安装脚本.

5、按照之前转存的软件(rpm)包, 重新生成光盘的report信息.

6、打包生成ISO文件,及MD5效验码.

光盘结构介绍:

* isolinux目录存放光盘启动时的安装界面信息

* images目录包括了必要的启动映像文件

* CentOS目录存放安装软件包及信息

* .discinfo文件是安装价质的识别信息

   安装时默认第一项是text自动安装,也可以选择第二项进行手动安装...

[root@CentOS ~]# mkdir /mnt/cdrom

[root@CentOS ~]# mount  /dev/cdrom  /mnt/cdrom

[root@CentOS~]# /usr/bin/rsync -a --exclude=Packages/ --exclude=repodata/ /mnt/cdrom/  /ISO/

[root@CentOS ~]# mkdir -p /ISO/{Packages,repodata}

[root@CentOS ~]# vi copy.sh

#!/bin/bash

cd /root

awk '/Installing/{print $2}' install.log | sed 's/^*://g' >package.txt

DVD='/mnt/cdrom/Packages'

PACKDIR='/root/package.txt'

NEW_DVD='/ISO/Packages'

while read LINE

do

cp ${DVD}/${LINE}*.rpm /${NEW_DVD} || echo "$LINE don't cp......."

done < package.txt

rm -f package.txt

[root@CentOS ~]# chmod +x copy.sh

[root@CentOS ~]# ./copy.sh

[root@CentOS ~]# ll /ISO/Packages/ |wc -l

(二)定制kickstart安装脚本ks.cfg,并修改/ISO/isolinux/isolinux.cfg文件,默认isolinux.cfg的权限为444,只能读,无法修改

[root@CentOS ~]# cd /ISO

[root@CentOS ISO]# cp ~/anaconda-ks.cfg isolinux/ks.cfg

[root@CentOS ISO]# vi  isolinux/ks.cfg

[root@CentOS ISO]# chmod 644 isolinux/isolinux.cfg

[root@CentOS ISO]# vi isolinux/isolinux.cfg

[root@CentOS ISO]# chmod 444  isolinux/isolinux.cfg


(三)安装anaconda repodata createrepo mkisofs等工具,执行createrepo程序生成repodata下的comps.xml文件

    以上是整个ISO的制作所有的操作过程,看起来绝对够简单吧!附件中是ks文件,希望这篇文章能够帮到你哦!

     最后找个例如winscp之类的工具将ISO文件传输到本机,就可以刻盘安装了...
