# 安装系统时只勾选必要的组件 保持系统的精简

# 操作时请按照此文档
# 创建文件夹
mkdir /ISO
mkdir -p /root/iso/

# copy镜像文件至/root/iso 挂载
mount -o loop /root/iso/CentOS-7-x86_64-DVD-1708.iso /mnt
# 同步/mnt/cdrom/下的文件到/ISO/路径下，除了Packages和repodata文件夹
/usr/bin/rsync -a --exclude=Packages/ --exclude=repodata/ /mnt/cdrom/ /ISO/

# 查看ISO下文件
ls /ISO/

CentOS_BuildTag EFI EULA GPL images isolinux LiveOS RPM-GPG-KEY-CentOS-7 RPM-GPGKEY-CentOS-Testing-7 TRANS.TBL
# 在/ISO/文件夹下新建Packages和repodata文件夹
mkdir -p /ISO/{Packages,repodata}

ls /ISO/

# ======================================================================
# 以下内容为，缩减rpm包数量，减少不必须的安装文件
# 问题：这类做法安装时提示--Error Checking Software Selection--导致安装失败
# 预估为安装包不完整，当把/mnt/cdrom/Packages下全部的rpm包放到/ISO/Packages中，安装完成
cd /root/iso/
vim copy_rpm.sh

#!/bin/bash
cd /root
rpm -qa > package.txt
DVD='/mnt/cdrom/Packages'
NEW_DVD='/ISO/Packages'
while read LINE
do
cp ${DVD}/${LINE}*.rpm /${NEW_DVD} || echo "\$LINE don't cp......."
done < package.txt
rm -rf package.txt

# 给执行权限
chmod +x copy_rpm.sh
# 执行copy程序
./copy_rpm.sh
# ======================================================================
# 如果报错则copy全部rpm包
cp /mnt/cdrom/Packages/* /ISO/Packages/
# 查看两个路径下包的数量
ll /mnt/cdrom/Packages/ | wc -l
ll /ISO/Packages/ | wc -l

# inst.ks为ks.cfg文件位置；
# hd:LABEL为介质标签，例如CentOS7。这个和后续生成ISO镜像文件的命令genisoimage的参数-V有关。
