一、制作環境准備
實驗環境：
VMware Workstation
CentOS-6.5-x86_64-minimal 最小化安裝
安裝後，我們會使用系統 /root 目錄下 install.log 和 anaconda-ks.cfg 這兩個文件（在此基礎上修改比較方便）
1.1 定制步驟
1、安裝最小化的操作系統.包括基本的系統和所需要的工具等.
比如:對於http,mysql等軟件,建議使用編譯的方式安裝, 然後打包放進去,可以減少許多依賴包的麻煩.
2、安裝系統後,收集系統已安裝的軟件包,使用腳本統一轉存到一個目錄中.
3、在安裝光盤復制images鏡像,從光盤啟動centos安裝所需的文件等.
4、定義自己的kickstart安裝腳本.
5、按照之前轉存的軟件(rpm)包, 重新生成光盤的report信息.
6、打包生成ISO文件，及MD5效驗碼.
1.2 安裝所需工具包
[root@linuxidc ~]# yum -y install anaconda repodata createrepo mkisofs rsync
1.3 下載CentOS 6.5鏡像
為了方便制作，我們可以在VMware、vbox、xen等虛擬環境中進行安裝，這裡我們選用了VMware作為制作環境。我們可以在官網或者其他比較近的鏡像站點下載CentOS 鏡像文件。CentOS-6.4-x86_64-minimal.iso
二、定制系統
2.1 光盤目錄結構
*isolinux 目錄存放光盤啟動時的安裝界面信息
*images 目錄包括了必要的啟動映像文件
*Packages 目錄存放安裝軟件包及信息
*.discinfo 文件是安裝價質的識別信息
MediaCentOS 目錄存放媒體中心安裝包
Repodata 目錄存放rpm包依賴信息
5.x 系列， boot.iso 存在於 images/ 這個目錄。
6.x 系列， 存放於 /isolinux 目錄下
6.x 網絡安裝需要在官網下載：netinstall.iso 鏡像文件。
2.2 掛載並拷貝文件
目錄規劃：
掛載目錄為： /mnt
定制光盤文件目錄： /root/iso
[root@linuxidc ~]# pwd
/root
[root@linuxidc ~]# mkdir iso # 建立iso文件制作目錄
[root@linuxidc ~]# mkdir -p ./iso/{Packages,repodata} # 建立軟件包目錄和repodata目錄
[root@linuxidc ~]# mount /dev/cdrom /mnt # 掛載 DVD
mount: block device /dev/sr0 is write-protected, mounting read-only
# 拷貝 源DVD鏡像中，除了Packages,repodata 目錄外的所有文件到 iso 目錄
[root@linuxidc ~]# /usr/bin/rsync -a --exclude=Packages --exclude=repodata /mnt/ ./iso/
[root@linuxidc ~]# ls iso
CentOS_BuildTag GPL Packages RPM-GPG-KEY-CentOS-6 RPM-GPG-KEY-CentOS-Testing-6
EFI images RELEASE-NOTES-en-US.html RPM-GPG-KEY-CentOS-Debug-6 TRANS.TBL
EULA isolinux repodata RPM-GPG-KEY-CentOS-Security-6
# 參考當前系統的安裝包，拷貝
[root@linuxidc ~]# awk '/Installing/ {print $2}' install.log | xargs -i cp /mnt/Packages/{}.rpm ./iso/Packages/
[root@linuxidc ~]# ls iso/Packages/ | wc -l
205
# 執行createrepo程序生成repodata下的comps.xml文件（重要）
#comps.xml 文件中包含了安裝時用戶所見到的與rpm相關的所有內容，它會檢查Packages下
# 的RPM包的依賴關系，安裝時如果缺少依賴包，它會提示您哪個RPM 包需要哪些依賴庫。
[root@linuxidc ~]# pwd
/root
# 編輯 shell 腳本， 並執行
#!/bin/bash
ISO_DIR=/root/iso
cd ${ISO_DIR}
declare -x discinfo=$(head -1 .discinfo)
cp /mnt/repodata/*-minimal-x86_64.xml ${ISO_DIR}/repodata/minimal-x86_64.xml
createrepo -g ${ISO_DIR}/repodata/minimal-x86_64.xml ${ISO_DIR}
createrepo -u "media://$discinfo" -g ${ISO_DIR}/repodata/*-minimal-x86_64.xml ${ISO_DIR}
###
到這裡，comps.xml文件和其他相關聯的文件已被重新生成到repodata目錄下。
Tips2：如果你新增或刪除了Packages目錄的RPM包，請重新生成comps.xml文件。
三、制作 ks.cfg 腳本
ks文件由系統安裝所創建的 anaconda-ks.cfg進行修改，當然也可以用system-config-kickstart工具制作而得。這裡大家需要根據實際情況進行修改：
默認root用戶密碼： 123456
靜態獲取地址
硬盤至少15G
[root@linuxidc ~]# pwd
/root
[root@linuxidc ~]# cp anaconda-ks.cfg ./iso/isolinux/ks.cfg
[root@linuxidc ~]# vim ./iso/isolinux/ks.cfg
## 請根據實際情況進行調整
# Kickstart file automatically generated byanaconda.

%end
四、修改 isolinux.cfg 配置文件，指定 ks 路徑
注意，編輯這個文件，需要強制保存。 :wq!
[root@linuxidc ~]# vi ./iso/isolinux/isolinux.cfg
default vesamenu.c32
#prompt 1

display boot.msg

五、生成iso鏡像，並生成 MD5校驗碼
## 注意所在的目錄
[root@linuxidc ~]# pwd
/root
[root@linuxidc ~]# cd iso
[root@linuxidc iso]# pwd
/root/iso
[root@linuxidc iso]# mkisofs -o CentOS-6.4_64.iso -input-charset utf-8 -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table -R -J -v -T -joliet-long /root/iso

六、安裝測試
可以通過 Filezilla ，winscp 等軟件把 iso 鏡像傳出來。然後可以通過虛擬機安裝測試，如果測試沒有問題，那麼就可以刻錄成光盤了。
通過 VMware Workstation 創建虛擬機，然後使用剛才我們創建的鏡像。然後啟動虛擬機，就會自動安裝了。是不是 so easy ...
