服务器评测
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images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@linuxidc ~]# 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
*images 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 images/ 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@linuxidc ~]# pwd
/root
[root@linuxidc ~]# mkdir iso # 建立iso文件制作目录
[root@linuxidc ~]# mkdir -p ./iso/{Packages,repodata} # 建立软件包目录和repodata目录
[root@linuxidc ~]# 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@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
# 参考当前系统的安装包，拷贝
[root@linuxidc ~]# awk ‘/Installing/ {print $2}’ install.log | xargs -i cp /mnt/Packages/{}.rpm ./iso/Packages/
[root@linuxidc ~]# 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@linuxidc ~]# 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@linuxidc ~]# pwd
/root
[root@linuxidc ~]# cp anaconda-ks.cfg ./iso/isolinux/ks.cfg
[root@linuxidc ~]# vim ./iso/isolinux/ks.cfg
## 请根据实际情况进行调整

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@linuxidc ~]# vi ./iso/isolinux/isolinux.cfg
default vesamenu.c32
#prompt 1

display boot.msg

五、生成iso镜像，并生成 MD5校验码
## 注意所在的目录
[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 …
