CentOS 6.0 在大家翘首以盼中姗姗来迟,但官方发布的DVD太过于庞大,很多组件其实在日常的生产环境中并用不上,所以基于此种情况,在这里我们就来对官方发布的DVD进行瘦身,只安装我们需要的组件,并实现自动安装,安装完毕后再对系统做基本的初始化,这样在生产环境中需要批量布署服务器的时候,显的效率非常高

1、定制安装系统,选择常用的组件
2、安装制作发行版所需的基本软件包
yum –y install createrepo mkisofs

3、生成安装系统所需的rpm文件列表
awk '/Installing/{print $2}' install.log |sed 's/^[0-9]*://g' >/root/packages.list

4、创建定制工作目录
mkdir -p /mnt/cdrom
mkdir -p /data/OS
mount /dev/cdrom /mnt/cdrom
rsync –a --exclude=Packages /mnt/cdrom /data/OS
mkdir /data/OS/Packages

5、复制精简后的RPM包
vi /data/cprmps.sh #创建自动复制RPM包脚本

  1. #!/bin/bash
  2. DEBUG=0
  3. CentOS_DVD=/mnt/cdrom
  4. ALL_RPMS_DIR=/mnt/cdrom/Packages #源光盘RPM包存放的目录
  5. KOS_RPMS_DIR=/data/OS/Packages #精简后RPM包存放的目录
  6. packages_list=/root/packages.list #精简后的RPM包列表
  7. number_of_packages=`cat $packages_list | wc -l`
  8. i=1
  9. while [ $i -le $number_of_packages ] ; do
  10. line=`head -n $i $packages_list | tail -n -1`
  11. name=`echo $line | awk '{print $1}'`
  12. version=`echo $line | awk '{print $3}' | cut -f 2 -d :`
  13. if [ $DEBUG -eq "1" ] ; then
  14. echo $i: $line
  15. echo $name
  16. echo $version
  17. fi
  18. if [ $DEBUG -eq "1" ] ; then
  19. ls $ALL_RPMS_DIR/$name-$version*
  20. if [ $? -ne 0 ] ; then
  21. echo "cp $ALL_RPMS_DIR/$name-$version* "
  22. fi
  23. else
  24. echo "cp $ALL_RPMS_DIR/$name-$version* $KOS_RPMS_DIR/"
  25. cp $ALL_RPMS_DIR/$name-$version* $KOS_RPMS_DIR/
  26. # in case the copy failed
  27. if [ $? -ne 0 ] ; then
  28. echo "cp $ALL_RPMS_DIR/$name-$version* "
  29. cp $ALL_RPMS_DIR/$name* $KOS_RPMS_DIR/
  30. fi
  31. fi
  32. i=`expr $i + 1`
  33. done

chmod +x cprpm.sh
./cprpm.sh


6、配置kickstart脚本
vi /data/OS/isolinux/kerry.cfg

  1. # Kickstart file automatically generated by anaconda.
  2. #Install OS instead of upgrade
  3. install
  4. #Use text mode install
  5. text
  6. #Use CDROM installation media
  7. cdrom
  8. lang en_US.UTF-8
  9. keyboard us
  10. #Skip the X Configuration
  11. skipx
  12. #Network information
  13. #network --device eth0 --onboot yes --bootproto static --ip 192.168.9.226 --netmask 255.255.255.0 --gateway 192.168.9.1 --nameserver 192.168.9.1 --noipv6 --hostname kerry-web-001
  14. network --bootproto dhcp --noipv6 --onboot=yes --hostname kerry-web-001
  15. #root -- 1q2w3e

  143. chmod 600 /etc/shadow

7、生成comps.xml
cd /data/OS
createrepo –g repodata/*-comps.xml /data/OS/

8、让系统从kickstart配置启动安装
vi /data/OS/isolinux/isolinux.cfg

default auto
label auto
kernel vmlinuz
append ks=cdrom:/isolinux/kerry.cfg initrd=initrd.img

9、生成ISO文件
cd /data/OS
declare -x discinfo=`head -1 .discinfo`
createrepo -u "media://$discinfo" -g repodata/*-comps.xml /data/OS/
mkisofs -R -J -T -r -l -d -joliet-long -allow-multidot -allow-leading-dots -no-bak -o /data/KerryOS-1.0-i386.iso -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table /data/OS

10、生成MD5检验码
/usr/bin/implantisomd5 /data/KerryOS-1.0-i386.iso
