簡單定制一個适合自己用的CentOS系統

實驗環境：VMware + CentOS5.6（64bit）

根據自己的習慣，将CentOS重新打包成一個新ISO，可以自動分區、選擇原件包，快速安裝系統。

先用虛拟機按照正常的流程安裝一個CentOS系統，接下來在這系統上去建立我們的定制系統：

1、挂載光驅

mount /dev/cdrom /mnt

2、建立臨時目錄

mkdir  -p /root/iso/CentOS

3、提取需要的RPM包，正常安裝好作業系統在/root目錄下會有install.log檔案，這個就是作業系統安裝RPM包的記錄，我們從這些記錄中，将所需的RPM包從/mnt/CentOS中複制到/root/iso/CentOS裡面去

#!/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、把原鏡像除了CentOS目錄外的檔案全部複制至/root/iso目錄下

cd /mnt  ls | grep -v CentOS | xargs -i cp -Rp {} /home/test/

5、把/root目錄下的anaconda-ks.cfg複制至/root/iso目錄下，并根據自己實際需要修改安裝要求

6、讓ISO按照anaconda-ks.cfg檔案來執行安裝

vi /root/iso/isolinux/isolinux.cfg Default  linux   修改成default linux  ks=cdrom:/anaconda-ks.cfg

7、生成comps.xml檔案

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/

然後下次需要重裝系統的時候就直接使用這個ISO啦，友善快捷！有個缺點就是密碼是按照anaconda-ks.cfg中設定的執行，再研究一下看看能不能設定密碼跟使用者互動的模式。
