Centos6 Merge method for two image files

1 , related directories:

/MNT/DVD1 and/MNT/DVD2 for mounting Centos mirrors

/mnt/dvd3 merged image file

/mnt/iso ISO Storage

Mkdir-p/mnt/dvd1/mnt/dvd2/mnt/dvd3/mnt/iso

2 , upload the CentOS image to the server, mount the CentOS image file

Mount-o LOOP/MNT/ISO/CENTOS-6.5-X86_64-BIN-DVD1.ISO/MNT/DVD1

Mount-o LOOP/MNT/ISO/CENTOS-6.5-X86_64-BIN-DVD2.ISO/MNT/DVD2

3 , copy files

First, copy all the files from the first DVD to the/MNT/DVD3 directory, and then copy all the rpm files from the Packages directory in the second DVD to the/mnt/dvd3/packages directory.

Cp-av/mnt/dvd1/mnt/dvd3

Cp-v/mnt/dvd2/packages/*.rpm/mnt/dvd3/packages/

4 , merging Trans.tbl

Append the TRANS.TBL information in the DVD2 to the DVD1 trans.tbl, and sort save

Cat/mnt/dvd2/packages/trans. TBL >>/mnt/dvd3/packages/trans. TBL

Mv/mnt/dvd3/packages/{trans. Tbl,trans. TBL. BAK}

Sort/mnt/dvd3/packages/trans. TBL. BAK >/mnt/dvd3/packages/trans. TBL

(Sort sort /mnt/dvd3/packages/trans.) TBL. Bak file, the result is output to /mnt/dvd3/packages/trans. TBL)

Rm-rf/mnt/dvd3/packages/trans. TBL. Bak

dvd3 It is already a merged file and can be used as a local source and as an ISO.

5 , backing up the Yum configuration file

Cd/etc/yum.repos.d

MV *.repo *.repo.bak (* represents repo file name)

6 , generate a new Yum configuration file

Vi/etc/yum.repos.d/centos-media.repo

[C6-media]

Name=centos-\ $releasever-media

Baseurl=file:///mnt/dvd3

Gpgcheck=0

Enabled=1

Gpgkey=file:///etc/pki/rpm-gpg/rpm-gpg-key-centos-6

7 , update yum source

Yum Clean all empties the cache

Yum Upgrade update Yum source

Yum Repolist View the number of Yum source packages

8 , packaging the/mnt/dvd3/as an ISO

Mkisofs-l-j-l-r-v "centos-6.*-x86_64"-o/mnt/iso/centos-6.*-x86_64-dvd.iso/mnt/dvd3

9 , unzip ISO image to use UltraISO, cannot use RAR

Do not know the problem is RAR or the image files caused by the virtual directory files, when using RAR decompression image file, the Repodata folder file *.gz will become a file without suffix, so as a source, will be error. You can add the GZ suffix to each file without any problems. But you can also use UltraISO extracted files are normal with *.gz suffix, it can be used normally.
