简单定制一个适合自己用的CentOS系统

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 mount /dev/cdrom /mnt  

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

# Kickstart file automatically generated by anaconda.

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/
