一、制作环境准备
实验环境：
VMware Workstation
CentOS-6.5-x86_64-minimal 最小化安装
安装后，我们会使用系统 /root 目录下 install.log 和 anaconda-ks.cfg 这两个文件（在此基础上修改比较方便）
1.1 定制步骤
1、安装最小化的操作系统.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p_w_picpaths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.
1.2 安装所需工具包
[root@skype ~]# yum -y install anaconda repodata createrepo mkisofs rsync
1.3 下载CentOS 6.5镜像
为了方便制作，我们可以在VMware、vbox、xen等虚拟环境中进行安装，这里我们选用了VMware作为制作环境。我们可以在官网或者其他比较近的镜像站点下载CentOS 镜像文件。CentOS-6.4-x86_64-minimal.iso
二、定制系统
2.1 光盘目录结构
*isolinux 目录存放光盘启动时的安装界面信息
*p_w_picpaths 目录包括了必要的启动映像文件
*Packages 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
MediaCentOS 目录存放媒体中心安装包
Repodata 目录存放rpm包依赖信息
5.x 系列， boot.iso 存在于 p_w_picpaths/ 这个目录。
6.x 系列， 存放于 /isolinux 目录下
6.x 网络安装需要在官网下载：netinstall.iso 镜像文件。
2.2 挂载并拷贝文件
目录规划：
挂载目录为： /mnt
定制光盘文件目录： /root/iso
[root@skype ~]# pwd
/root
[root@skype ~]# mkdir iso # 建立iso文件制作目录
[root@skype ~]# mkdir -p ./iso/{Packages,repodata} # 建立软件包目录和repodata目录
[root@skype ~]# mount /dev/cdrom /mnt # 挂载 DVD
mount: block device /dev/sr0 is write-protected, mounting read-only
# 拷贝 源DVD镜像中，除了Packages,repodata 目录外的所有文件到 iso 目录
[root@skype ~]# /usr/bin/rsync -a --exclude=Packages --exclude=repodata /mnt/ ./iso/
[root@skype ~]# ls iso
CentOS_BuildTag GPL Packages RPM-GPG-KEY-CentOS-6 RPM-GPG-KEY-CentOS-Testing-6
EFI p_w_picpaths RELEASE-NOTES-en-US.html RPM-GPG-KEY-CentOS-Debug-6 TRANS.TBL
EULA isolinux repodata RPM-GPG-KEY-CentOS-Security-6
# 参考当前系统的安装包，拷贝
[root@skype ~]# awk '/Installing/ {print $2}' install.log | xargs -i cp /mnt/Packages/{}.rpm ./iso/Packages/
[root@skype ~]# ls iso/Packages/ | wc -l
205
# 执行createrepo程序生成repodata下的comps.xml文件（重要）
#comps.xml 文件中包含了安装时用户所见到的与rpm相关的所有内容，它会检查Packages下
# 的RPM包的依赖关系，安装时如果缺少依赖包，它会提示您哪个RPM 包需要哪些依赖库。
[root@skype ~]# pwd
/root
# 编辑 shell 脚本， 并执行
#!/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}
###
到这里，comps.xml文件和其他相关联的文件已被重新生成到repodata目录下。
Tips2：如果你新增或删除了Packages目录的RPM包，请重新生成comps.xml文件。
三、制作 ks.cfg 脚本
ks文件由系统安装所创建的 anaconda-ks.cfg进行修改，当然也可以用system-config-kickstart工具制作而得。这里大家需要根据实际情况进行修改：
默认root用户密码： 123456
静态获取地址
硬盘至少15G
[root@skype ~]# pwd /root [root@skype ~]# cp anaconda-ks.cfg ./iso/isolinux/ks.cfg [root@skype ~]# vim ./iso/isolinux/ks.cfg ## 请根据实际情况进行调整 # Kickstart file automatically generated byanaconda. #version=DEVEL install cdrom lang en_US.UTF-8 keyboard us network --onboot yes --device eth0 --bootproto static --noipv6 --ip=192.168.3.132 --netmask=255.255.255.0 --gateway=192.168.3.254 rootpw --iscrypted$6$060kt9rryFXbrlgx$WWWNQYLnpz0Es8dTlouy3LXqjTdHIRToojidbpYoZrd2ETOJ.JsNbgnMylQVbFRThPZwSdRKJcrAml7LQDdR00 firewall --service=ssh authconfig --enableshadow --passalgo=sha512 selinux --disabled timezone --utc Asia/Chongqing text firstboot --disable logging --level=info reboot bootloader --location=mbr --driveorder=sda --append="crashkernel=auto rhgb quiet" zerombr # The following is the partitioninformation you requested # Note that any partitions you deleted arenot expressed # here so unless you clear all partitionsfirst, this is # not guaranteed to work #clearpart --none #part /boot --fstype=ext4 --size=200 #part swap --size=2048 #part / --fstype=ext4 --grow --size=200 clearpart --all --initlabel part /boot --fstype=ext4 --size=200 part swap --size=2048 part / --fstype=ext4 --size=10240 part /data --fstype=ext4 --size=1 --grow # repo --name="CentOS" --baseurl=cdrom:sr0 --cost=100 %packages --nobase @core %end
四、修改 isolinux.cfg 配置文件，指定 ks 路径
注意，编辑这个文件，需要强制保存。 :wq!
[root@skype ~]# vi ./iso/isolinux/isolinux.cfg default vesamenu.c32 #prompt 1 timeout 600 display boot.msg menu background splash.jpg menu title Welcome to CentOS 6.5! menu color border 0 #ffffffff #00000000 menu color sel 7 #ffffffff #ff000000 menu color title 0 #ffffffff #00000000 menu color tabmsg 0 #ffffffff #00000000 menu color unsel 0 #ffffffff #00000000 menu color hotsel 0 #ff000000 #ffffffff menu color hotkey 7 #ffffffff #ff000000 menu color scrollbar 0 #ffffffff #00000000 label linux menu label ^Install or upgrade an existing system menu default kernel vmlinuz append initrd=initrd.img ks=cdrom:/isolinux/ks.cfg # 仅修改这里即可 label vesa menu label Install system with ^basic video driver kernel vmlinuz append initrd=initrd.img xdriver=vesa nomodeset label rescue menu label ^Rescue installed system kernel vmlinuz append initrd=initrd.img rescue label local menu label Boot from ^local drive localboot 0xffff label memtest86 menu label ^Memory test kernel memtest append -
五、生成iso镜像，并生成 MD5校验码
## 注意所在的目录 [root@skype ~]# pwd /root [root@skype ~]# cd iso [root@skype iso]# pwd /root/iso [root@skype iso]# mkisofs -o CentOS-6.4_64.iso -input-charset utf-8 -b isolinux/isolinux.bin -c

六、安装测试
可以通过 Filezilla ，winscp 等软件把 iso 镜像传出来。然后可以通过虚拟机安装测试，如果测试没有问题，那么就可以刻录成光盘了。
通过 VMware Workstation 创建虚拟机，然后使用刚才我们创建的镜像。然后启动虚拟机，就会自动安装了。是不是 so easy ...
