环境说明:
相关目录说明:
/CentOS_ISO/DVD1 #用于挂载 Centos dvd1镜像目录
/CentOS_ISO/DVD2 #用于挂载 Centos dvd2镜像目录
/CentOS_ISO/CentOS #用于存放合并的镜像文件目录
1、创建目录
mkdir -p /CentOS_ISO/DVD1 /CentOS_ISO/DVD2 /CentOS_ISO/CentOS
2、上传 Centos 镜像到服务器,挂载 Centos 镜像文件
mount -o loop /CentOS_ISO/CentOS-6.10-x86_64-bin-DVD1.iso /CentOS_ISO/DVD1
mount -o loop /CentOS_ISO/CentOS-6.10-x86_64-bin-DVD2.iso /CentOS_ISO/DVD2
3、拷贝文件到 合并镜像目录 /CentOS_ISO/CentOS
首先, 拷贝第一张cdrom中的所有文件到 /CentOS_ISO/CentOS 目录下,然后, 只拷贝第二张 cdrom 中 Packages 目录下的所有RPM文件到 /CentOS_ISO/CentOS 目录下
cp -rfT /CentOS_ISO/DVD1 /CentOS_ISO/CentOS
cp -af /CentOS_ISO/DVD2/Packages/*.rpm /CentOS_ISO/CentOS/Packages/
4、追加TRANS.TBL并排序
将cdrom2中TRANS.TBL的信息追加到cdrom1中TRANS.TBL后面, 并排序保存
cat /CentOS_ISO/DVD2/Packages/TRANS.TBL >> /CentOS_ISO/CentOS/Packages/TRANS.TBL
mv /CentOS_ISO/CentOS/Packages/{TRANS.TBL,TRANS.TBL.bak}
sort /CentOS_ISO/CentOS/Packages/TRANS.TBL.bak > /CentOS_ISO/CentOS/Packages/TRANS.TBL
rm -rf /CentOS_ISO/CentOS/Packages/TRANS.TBL.bak
5、生成镜像
方法一、使用普通的文件系统转换,还不能做成启动光盘的iso文件,只能用来当作yum源。
mkisofs -r -o /CentOS_ISO/CentOS-6.10-x86_64-Everything.iso /CentOS_ISO/CentOS/
方法二、转换为可以做为启动光盘的文件,需要使用CentOS官网上的脚本运行 (mkdvdiso.sh)
官网脚本下载地址:https://wiki.centos.org/TipsAndTricks/CDtoDVDMedia
#mkdvdiso.sh 脚本代码放在文末
#用法: mkdvdiso.sh source /destination/DVD.iso
#“source”可以是包含一组isos的目录,也可以是类似ftp站点的分解树
#如果安装树不包含.discinfo文件,则必须从CD或DVD的顶层获得一个文件。
上传脚本并修改权限:
chmod +x mkdvdiso.sh
安装需要的环境:
yum install -y isomd5sum
yum install -y createrepo
sh mkdvdiso.sh /CentOS_ISO/CentOS /CentOS_ISO/CentOS-6.10-x86_64-Everything.iso
6、卸载镜像
umount /CentOS_ISO/DVD1
umount /CentOS_ISO/DVD2
7、 删除目录
rm -rf /CentOS_ISO/DVD1 /CentOS_ISO/DVD2 /CentOS_ISO/CentOS

#mkdvdiso.sh 脚本代码如下:
# by Chris Kloiber <[email protected]> # Mods under CentOS by Phil Schaffner <[email protected]> # A quick hack that will create a bootable DVD iso of a Red Hat Linux # Distribution. Feed it either a directory containing the downloaded # iso files of a distribution, or point it at a directory containing # the "RedHat", "isolinux", and "images" directories. # This version only works with "isolinux" based Red Hat Linux versions. # Lots of disk space required to work, 3X the distribution size at least. # GPL version 2 applies. No warranties, yadda, yadda. Have fun. # Modified to add sanity checks and fix CentOS4 syntax errors # TODO: # Add checks for available disk space on devices holding output and # temp files. # Add optional 3rd parameter to specify location of temp directory. # Create .discinfo if not present.
