定制centos发行版

//轻量级Centos定制发行版
====================================================================================================
一、基础

//操作环境:
VM+CentOS-6.4-x86_64-minimal.iso

//基本软件
yum -y install createrepo genisoimage

//VM需设置1个光驱 挂载DVD1
安装centos6.4X 86_64系统，所需组件自行定义，安装后得到install.log和anaconda-ks.cfg文件

//初始目录
mkdir /mnt/cd1 #建立光盘的挂载目录
mount /dev/cdrom /mnt/cd1 #挂载DVD
mkdir -p /root/centos_1905/Packages #建立定制光盘文件目录

二、定制系统文件的准备

新定制系统由以上系统组件包说决定，文件由install.log安装日志得来

vi /root/cp_files.sh

#!/bin/bash
for i in $(awk '/Installing/ {print $2}' install.log)
do
cp /mnt/cd1/Packages/${i}.rpm /root/centos_1905/Packages
[ $? != 0 ] && echo "copy ${i} is faied"
done

//拷贝文件
rsync -a --exclude=Packages /mnt/cd1/ /root/centos_1905/

三、下载Development Tools相关软件

另找机器，通过yum -y groupinstall "Development Tools"缓存相关软件包

需安装其他基础依赖包，都可通过yum准备相关文件。

//开启缓存
vi /etc/yum.conf
keepcache=1

拷贝相关软件到Packages下

//find . -name "*.rpm"|xargs -i mv {} ~/temp

三、ks文件准备 (非自动安装忽略此步)

ks文件由系统安装所得anaconda-ks.cfg进行修改所得 (也可用 system-config-kickstart 生成)
密码生成工具 grub-crypt

vi /root/centos_1905/isolinux/ks.cfg

# Kickstart file automatically generated by anaconda.

#version=DEVEL
install
cdrom
lang en_US.UTF-8
keyboard us
network --onboot no --device eth0 --bootproto dhcp --noipv6
network --onboot no --device eth1 --bootproto dhcp --noipv6
rootpw --iscrypted $6$ap3J1vcG32p9wu7m$Q4YQJdR4jvxNjhTDNhw0d/qFdcd/TufkoZ3GZ4VZ7fkna3oZEnAYrXAqrBk11b6S6.gAWqsb8.EBAuerI8k/l.
firewall --service=ssh
authconfig --enableshadow --passalgo=sha512
selinux --disabled
timezone --utc Asia/Chongqing
bootloader --location=mbr --driveorder=xvda --append="crashkernel=auto console=hvc0 rhgb quiet"
# The following is the partition information you requested
# Note that any partitions you deleted are not expressed
# here so unless you clear all partitions first, this is
# not guaranteed to work
#clearpart --linux --drives=xvda
#volgroup VolGroup --pesize=4096 pv.202002
#logvol /home --fstype=ext4 --name=lv_home --vgname=VolGroup --grow --size=100
#logvol / --fstype=ext4 --name=lv_root --vgname=VolGroup --grow --size=1024 --maxsize=51200
#logvol swap --name=lv_swap --vgname=VolGroup --grow --size=4000 --maxsize=4000

#part /boot --fstype=ext4 --size=500
#part pv.202002 --grow --size=1

#repo --name="CentOS" --baseurl=cdrom:xvdd --cost=100

%packages --nobase
@core
%end

四、让系统从kickstart配置启动安装 (非自动安装忽略此步)

vi /root/centos_1905/isolinux/isolinux.cfg

default auto
timeout 600
display boot.msg

menu background splash.jpg
menu title Welcome to CentOS 6.4!
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 auto
menu label ^Auto Install system
menu default
kernel vmlinuz
append ks=cdrom:/isolinux/ks.cfg initrd=initrd.img

label linux
menu label ^Install or upgrade an existing system
menu default
kernel vmlinuz
append initrd=initrd.img
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、重新生成comps.xml

//清空repodata
rm -rf /root/centos_1905/repodata/*

//生成XML(详见附录)
vi /root/centos_1905/repodata/comps.xml

//生成依赖 comps.xml
createrepo -g /root/centos_1905/repodata/comps.xml /root/centos_1905/

mv /root/centos_1905/repodata/*-comps.xml /root/centos_1905/repodata/comps.xml

cd /root/centos_1905/
declare -x discinfo=$(head -1 .discinfo)
createrepo -u "media://$discinfo" -g /root/centos_1905/repodata/comps.xml /root/centos_1905/

六、ISO文件的生成

mkisofs -o Centos_1905-text-6.4-x86_64-minimal.iso -input-charset utf-8 -b isolinux/isolinux.bin -c isolinux/boot.cat -joliet-long -no-emul-boot -boot-load-size 4 -boot-info-table -R -J -v -V centos_1905 -T /root/centos_1905

mkisofs -o Centos_1905_all_6_14-6.4-x86_64-minimal.iso -input-charset utf-8 -b isolinux/isolinux.bin -c isolinux/boot.cat -joliet-long -no-emul-boot -boot-load-size 4 -boot-info-table -R -J -v -V centos_1905 -T /root/centos_1905

mkisofs -o Centos_text-6.5-x86_64-minimal.iso -input-charset utf-8 -b isolinux/isolinux.bin -c isolinux/boot.cat -joliet-long -no-emul-boot -boot-load-size 4 -boot-info-table -R -J -v -V centos_1905 -T /root/centos_1905

mkisofs -o Centos_1905-6.5-x86_64-minimal.iso -input-charset utf-8 -b isolinux/isolinux.bin -c isolinux/boot.cat -joliet-long -no-emul-boot -boot-load-size 4 -boot-info-table -R -J -v -V centos_1905 -T /root/centos_1905

//打包普通
mkisofs -o m1905.iso -input-charset utf-8 -joliet-long -R -J -v -V centos_1905 -T /root/shell

七、生成检验
//yum install anaconda

/usr/bin/implantisomd5 /root/iso/Centos_1905-6.5-x86_64-minimal.iso

//拷贝去安装
scp Centos_1905-6.5-x86_64-minimal.iso root@192.168.3.200:/home/public/ISO

//绿色+开发包
Centos_text-6.5-x86_64-minimal.iso
===================================================================================
yum -y groupinstall "Development tools"
yum -y install wget
yum -y install lrzsz

//绿色+开发包+自带监控+票务基础包
Centos_1905-6.5-x86_64-minimal.iso
===================================================================================
基于上面系统

wget http://mirrors.sohu.com/fedora-epel/6/x86_64/epel-release-6-8.noarch.rpm && rpm -ivh epel-release-6-8.noarch.rpm

yum -y install ntp
yum -y install pcre pcre-devel zlib zlib-devel openssl openssl-devel
yum -y install cmake ncurses ncurses-devel libaio libaio-devel
yum -y install libxml2 libxml2-devel libjpeg-turbo libjpeg-turbo-devel libpng libpng-devel giflib giflib-devel freetype freetype-devel gd gd-devel glibc glibc-devel glib2 glib2-devel curl curl-devel e2fsprogs e2fsprogs-devel openssl openssl-devel libmcrypt-devel mhash mhash-devel
yum -y install lzo lzo-devel pam pam-devel automake pkgconfig

yum -y install openvpn
yum -y install salt-minion
yum -y install zabbix22-agent

//绿色+开发包+自带监控+票务基础包+票务系统
Centos_1905_pw-6.5-x86_64-minimal.iso

//绿色+开发包+自带监控+票务基础包+票务TMS
Centos_1905_tms-6.5-x86_64-minimal.iso

//绿色+开发包+自带监控+票务基础包+中心系统
Centos_1905_center-6.5-x86_64-minimal.iso

//聚包
mkdir ~/packages
find /mnt/cd1/Packages/ -name "*.rpm"|xargs -i cp {} ~/Packages
find /var/cache/yum/x86_64/6/ -name "*.rpm"|xargs -i cp {} ~/Packages

//快速配置文件
1、相关软件包
ls *.rpm > rpm_list.txt

2、RPM 截取包名和版本号 生成相关XML文件

//快速安装
======================================================
mkdir -p /root/centos_1905/Packages

cp ks.cfg /root/centos_1905/isolinux/ks.cfg
cp isolinux.cfg /root/centos_1905/isolinux/isolinux.cfg

附录 剔除低版本RPM 生成comps.xml
======================================================
1、将所有RPM包放到一个文件夹下 find /var/cache/yum -name *.rpm | xargs -i cp {} ~/pk/
2、整理出RPM包列表 ls *.rpm > rpm_list.txt
3、运行如下脚本 生成 comps.xml

<?php

//rpm_list.txt
//ls *.rpm > rpm_list.txt

$list = file_get_contents('rpm_list.txt');

$list_arr = explode("\n",$list);

$ok_arr = array();
$no_arr = array();

foreach($list_arr as $val)
{
if($val)
{

//正则分割 软件名 + 版本
$val_t_arr = preg_split("/(-[\d].)(.*)/",$val,0,3);

$key = $val_t_arr[0];
$val = $val_t_arr[1].$val_t_arr[2];

if(isset($ok_arr[$key]))
{
$re = strcmp($ok_arr[$key],$val);

//var_dump($ok_arr[$key]);
//var_dump($val);
//var_dump($re);

if($re > 0)
{
$no_arr[$key] = $val;
}
else
{
$no_arr[$key] = $ok_arr[$key];
$ok_arr[$key] = $val;
}

}
else
{
$ok_arr[$key] = $val;
}
}
}

//var_dump($ok_arr);
$list = '';
foreach($ok_arr as $key => $val)
{
$list .= " <packagereq type='mandatory'>".$key."</packagereq>"."\n";
}

$head = "<?xml version="1.0" encoding="UTF-8"?>

//替换图片
==============================================

1、找到 images/install.img

2、挂在images
mount -o loop -t squashfs install.img /mnt

3、拷贝出内容
mkdir ~/tmp
rsync -av /mnt/ ~/tmp

4、更换图片
cd ~/tmp/usr/share/anaconda/pixmaps

5、重新打包
mksquashfs ~/tmp/ install_v1.img -all-root

6、更替install.img

//更换欢迎语
==============================================

1、找到 isolinux/initrd.img

2、解压
mkdir ~/tmp2
cd ~/tmp2
xz -dc ~/centos_1905_micro_6.5/isolinux/initrd.img | cpio -id

3、修改
vi .buildstamp

4、重新打包
