linux 中如何将两个iso合成一个

如何将两个iso合成一个

如何将两张iso镜像文件合成一个iso镜像

• 环境我们拿centos 6.9 版本中的两个镜像合成一个完整和做启动光盘。
• 从centso官网上下载一个光盘合成脚本https://wiki.centos.org/
• 我这已经下载好了我把脚本内容贴出来，可以直接用

#!/bin/bash# by Chris Kloiber <[e-mail]># Mods under CentOS by Phil Schaffner <[e-mail]># 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.OS_VER=\$((test -e /etc/fedora-release && rpm -qf /etc/fedora-release --qf "FC%{VERSION}") \|| (test -e /etc/redhat-release && rpm -qf /etc/redhat-release --qf "EL%{VERSION}") \|| echo OS_unknown)case "$OS_VER" in  EL[45]*|FC?)

• 现在把两张centos镜像挂载到/mnt上面

  mount /dev/cdrom /mnt/ 把iso镜像挂载到mnt上  mkdir /app/iso1  创建一个文件夹  cp -rp /mnt/*  /app/iso1 将第一张光盘里面所有的内容全部复制过去  然后在复制二张光盘的，也是要先把光盘挂载到mnt上，注意一点由于第一张全部复制的，所有第二张盘只要复制包文件  cp -r /mnt/Packages/* iso1/Packages/  然后在运行脚本   ./mkdvdiso.sh --help 但是在查看帮助时让我们安装一个校验光盘的包，给装上就好了rpm -iv /mnt/Packages/isomd5sum-devel-1.0.6-1.el6. ./mkdvdiso.sh /app/iso1 /app/centso6.9.iso 运行脚本

• 这样就成功，现在我们用ftp服务器给传到win7上。
