实验环境：VMware + CentOS5.6（64bit）
根据自己的习惯，将CentOS重新打包成一个新ISO，可以自动分区、选择原件包，快速安装系统。
先用虚拟机按照正常的流程安装一个CentOS系统，接下来在这系统上去建立我们的定制系统：
1、挂载光驱
2、创建临时目录
mkdir -p /root/iso/CentOS |
3、提取需要的RPM包，正常安装好操作系统在/root目录下会有install.log文件，这个就是操作系统安装RPM包的记录，我们从这些记录中，将所需的RPM包从/mnt/CentOS中复制到/root/iso/CentOS里面去
#!/bin/bash
cd /root
awk ‘/Installing/{print $2}’ install.log | sed ‘s/^[0-9]*://g’ >package.txt
DVD=’/mnt/CentOS’
PACKDIR=’/root/package.txt’
NEW_DVD=’/root/iso/CentOS/’
while read LINE
do
cp ${DVD}/${LINE}*.rpm /${NEW_DVD} || echo “$LINE don’t cp…….”
done < package.txt
rm -f package.txt |
4、把原镜像除了CentOS目录外的文件全部复制至/root/iso目录下
cd /mnt
ls | grep -v CentOS | xargs -i cp -Rp {} /home/test/ |
5、把/root目录下的anaconda-ks.cfg复制至/root/iso目录下，并根据自己实际需要修改安装要求

6、让ISO按照anaconda-ks.cfg文件来执行安装
vi /root/iso/isolinux/isolinux.cfg
Default linux 修改成default linux ks=cdrom:/anaconda-ks.cfg |
7、生成comps.xml文件
yum -y install createrepo mkisofs
cd /root/iso
createrepo -g repodata/*comps.xml /root/iso/ |
8、制作ISO
mkisofs -o MyCentOS.iso -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table -R -J -v -T /root/iso/ |
然后下次需要重装系统的时候就直接使用这个ISO啦，方便快捷！有个缺点就是密码是按照anaconda-ks.cfg中设定的执行，再研究一下看看能不能设定密码跟用户交互的模式。
