准备环境：先手动安装一台centos6.4系统
①建立目录iso，挂载镜像
yum -y install createrepo mkisofs
mkdir /iso
mount /dev/cdrom /media
②copy镜像文件到 iso目录
cp -a /media/ /iso
③ 编辑ks.cfg文件
cat /iso/media/ks.cfg

⑤精简rpm包缩小iso镜像文件，删除java、eclipse的rpm包，寻找占用空间大且不必要的rpm包删除
cd /iso/media/Packages/
ls|grep ^java |xargs rm -f
ls|grep ^eclipse|xargs rm -f
⑥ copy需要的comps.xml文件
cd /iso/media
createrepo -g repodata/*-comps.xml /iso/media/
注（如果是oracle Linux，就执行下面的命令）
createrepo -g repodata/*-comps-rhel6-Server.xml /iso/media/
⑦ 生成iso文件，在tmp目录下
mkisofs -r -T -V "CentOS" -input-charset utf-8 -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table -o /tmp/CENTOS_6.4_FINAL-NEW.iso /iso/media/

⑤精简rpm包缩小iso镜像文件，删除java、eclipse的rpm包，寻找占用空间大且不必要的rpm包删除
cd /iso/media/Packages/
ls|grep ^java |xargs rm -f
ls|grep ^eclipse|xargs rm -f
⑥ copy需要的comps.xml文件
cd /iso/media
createrepo -g repodata/*-comps.xml /iso/media/
注（如果是oracle Linux，就执行下面的命令）
createrepo -g repodata/*-comps-rhel6-Server.xml /iso/media/
⑦ 生成iso文件，在tmp目录下
mkisofs -r -T -V "CentOS" -input-charset utf-8 -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table -o /tmp/CENTOS_6.4_FINAL-NEW.iso /iso/media/
