centos6.4合并两个DVD作为本地yun源
创建目录将iso文件上传
[root@test ~]# mkdir /iso
创建挂载目录
[root@test ~]# mkdir -p /mnt/cdrom
挂载
[root@test ~]# mount -o loop/iso/CentOS-6.4-x86_64-bin-DVD2.iso /mnt/cdrom/
检查挂载
[root@test ~]# df
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/sda1 51605116 7518012 41465716 16% /

/iso/CentOS-6.4-x86_64-bin-DVD2.iso 1418348 1418348 0 100% /mnt/cdrom
配置yum
备份
[root@test ~]#cd /etc/yum.repos.d/
[root@test yum.repos.d]# ls
CentOS-Base.repo CentOS-Debuginfo.repo CentOS-Media.repo CentOS-Vault.repo [root@test yum.repos.d]#mkdir ./bak
[root@test yum.repos.d]# mv ./*.repo ./bak
[root@test yum.repos.d]# ls
bak
[root@test yum.repos.d]# cd bak
[root@test bak]# ls
CentOS-Base.repo CentOS-Debuginfo.repo CentOS-Media.repo CentOS-Vault.repo
[root@test bak]# cp CentOS-Media.repo../myself.repo
[root@test bak]# cd ..
[root@test yum.repos.d]# ls
bak myself.repo
[root@test yum.repos.d]# vi myself.repo
# CentOS-Media.repo
#
# This repo can be used with mounted DVD media, verify the mount point for
# CentOS-6. You can use this repoand yum to install items directly off the
# DVD ISO that we release.
#
# To use this repo, put in your DVD and useit with the other repos too:
# yum --enablerepo=c6-media [command]
#
# or for ONLY the media repo, do this:
#
# yum --disablerepo=\* --enablerepo=c6-media [command]
[c6-media]

file:///media/cdrom/
file:///media/cdrecorder/
gpgcheck=1

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6
将上面内容的baseurl/ gpgcheck/ enabled更改为下面内容
baseurl=file:///mnt/cdrom
gpgcheck=0
enabled=1

Trying other mirror.
Error: Cannot retrieve repository metadata(repomd.xml) for repository: c6-media. Please verify its path and try again
出现错误的原因为第二个包中没有repomd.xml，这个文件我理解就是yum中包的一个索引以及各个包的详细信息等。也就说第二个包不能单独作为yun源。那么尝试下第一个包。

成功了，但是需要注意的是可以yum的包有6000多个，但是真正存在的包只有将近4000个。

合并两个iso
创建目录
[root@test cdrom1]# mkdir /mnt/cdrom1
[root@test cdrom1]# mkdir /mnt/cdrom2
[root@test cdrom1]# mkdir /mnt/cdrom3
挂载
[root@test cdrom1]# mount -o loop/iso/CentOS-6.4-x86_64-bin-DVD1.iso /mnt/cdrom1
[root@test cdrom1]# mount -o loop/iso/CentOS-6.4-x86_64-bin-DVD2.iso /mnt/cdrom2
拷贝
[root@test cdrom1]# cp -av /mnt/cdrom1//mnt/cdrom3
[root@test cdrom1]# cp -v/mnt/cdrom2/Packages/*.rpm /mnt/cdrom3/cdrom1/Packages/
合并TRANS.TBL
[root@test cdrom1]# cat/mnt/cdrom2/Packages/TRANS.TBL >> /mnt/cdrom3/cdrom1/Packages/TRANS.TBL
mv /mnt/cdrom3/cdrom1/Packages/TRANS.TBL/mnt/cdrom3/cdrom1/Packages/TRANS.TBL.bak
[root@test cdrom1]# sort/mnt/cdrom3/cdrom1/Packages/TRANS.TBL.bak > /mnt/cdrom3/cdrom1/Packages/TRANS.TBL
跟新yum配置，完成。
