多少人爱你青春欢畅的时辰, 爱你的美丽假意和真心, 只有一个人爱你那朝圣者的灵魂, 爱你衰老了的连上痛苦的皱纹.

###拷贝光盘内容到/disk，排除Packages目录
#cd /mnt/cdrom
#ls -a|grep -v "Packages"|xargs -i cp -rp {} /disk/
###生成RPM包packages.list列表
build_packages_list(){

2.Package kernel
Basic tools:
bash# yum -y install anaconda repodata createrepo mkisofs yum-utils anacondaanaconda-help busybox-anaconda anaconda-runtime
3.Copy necessary RPM from ISO
Bash# cat /Disk/.discinfo
1385726732.061157
6.5
x86_64
ALL
Bash# find /kvm/diskimg/ -name TRANS.TBL -exec rm -f {} \; -print
4.Define Packages u need
Packages# rm -f initscripts*rpm
Packages# yumdownloader initscripts
Packages# ls kernel-*
kernel-2.6.32-431.el6.x86_64.rpm
kernel-firmware-2.6.32-431.el6.noarch.rpm
Packages# rm -f kernel-*
Packages# cp kernel.rpm to Packages/

7.Update isolinux.cfg
Edit these code:
vi isolinux/isolinux.cfg
labels linux
menu label ^Install or upgrade an existing system
menu default
kernel vmlinuz
append ks=cdrom:/isolinux/myks.cfg initrd=initrd.img
8.Transfer to ISO
bash# cd /Disk
Disk# mkisofs -o ../J-k3.17.0+base6.5V19.iso -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table -R -J -v -T /kvm/diskimg/
/usr/bin/implantisomd5 ../J-k3.17.0+base6.5V19.iso
1.Reading initrd.img
[root@UCSKVMS003 tmp]# file initrd-kernel_3.17.0+.img
initrd-kernel_3.17.0+.img: ASCII cpio archive (SVR4 with no CRC)
Exert cpio format:
[root@UCSKVMS003 initrd0]# cpio -idmv
# file initrd.img
initrd.img: LZMA compressed data, streamed
Exert LZMA format
[root@UCSKVMS003 initrd6.5]# xz -dc tinitrd6.5.img | cpio -id
2.Compress initrd
bash#cd /lib/modules/`uname -r`
bash#mkinitrd /tmp/initrd.`uname -r`.img `uname -r`
bash#cd /tmp
bash#mv initrd.`uname –r`.img initrd.`uname –r`.img.gz
bash#gunzip initrd.`uname -r`.img.gz
cpio
#假设当前目录位于准备好的initrd文件系统的根目录下
bash# find . | cpio -c -o > ../initrd.img
bash# gzip ../initrd.img
bash# make mrproper
bash# make menuconfig
bash# make clean
LZMA format
#find . | cpio -c -o | xz -9 --format=lzma > initrd.img
rpm -qpR NetworkManager-glib-0.8.1-66.el6.i686.rpm

9.Repodata optimization
1. comps.xml include multi-language
2. remove the unness我们先去除不需要的语言,这里我只需要英文,
3
sed -ri '/xml:lang/ {/en_GB|zh_CN/!d}' comps.xml # 如果需要保留其他语言比如中文,在en_GB后添加"?zh_CN"
configure network ks.cfg
#####
配置网络信息；在网络安装（NFS/HTTP/FTP）时必须指定；
--bootproto=dhcp|bootp|static 指定ip获取方式，默认为dhcp/bootp;
--device= 设置安装时激活来进行系统安装的网卡设备；该参数只在kickstart文件为本地文件时有效；若kickstart配置文件在网络上，安装程序会先初始化网卡然后去寻找kickstart文件；
--ip= ip设置
--gateway= 网关
--nameserver= DNS设置
--nodns 不设置DNS
--netmask= 掩码
--hostname= 设置安装后主机名称
--onboot= 设置是否在系统启动时激活网卡
--class= 设置DHCP的class值
--noipv4 禁用该设备的ipv4功能
--noipv6 禁用该设备的ipv6功能
如将网络模式设置为静态模式，则必须在一行内写上ip，netmask、dns、gateway等信息；
例：
network –bootproto=static –ip=1.1.1.1 --metmask=255.0.0.0 --gateway=1.1.1.254 --nameserver=1.1.1.2
network --bootproto=dhcp --device=eth0
