Create a local repo from a install DVD

Create a local repo from a install DVD

There has been a few threads with people asking how to create a local repo from the install DVD lately so I thought I would share the method I use.

I will be using the ScientificLinux 6.1x86_64DVD installation DVD and the Gnome Desktop Environment for this guide.

Start by creating a directory for the local repo:

CODE

su -c 'mkdir /SL_DVD_localrepo'

Then we put the DVD in the reader. The DVD will be auto-mounted in the /media directory.
We now need to copy the .rpm files from the Packages folder inside the DVD to the new directory we created “/SL_DVD_localrepo“. The easiest way is to use the < tab> key for auto-complete function.

CODE

su - cp /media/<TAB>/Packages/*.rpm /SL_DVD_localrepo

When I used the auto-complete <tab> key above it found/completed the directory of the DVD.

We now need to create a repo from the directory /SL_DVD_localrepo . This requires the package “createrepo” . If you do not have the package createrepo installed :

CODE

cd /SL_DVD_localrepo yum localinstall createrepo<tab>

Once you have the package “createrepo” installed you can create the repo with:

CODE

createrepo /SL_DVD_localrepo

The last thing to do is create a repo file (for this purpose I used gedit but you can use whatever text editor you prefer) :

CODE

gedit /etc/yum.repos.d/SL_DVD_localrepo.repo

Make the SL_DVD_localrepo.repo file read as follows and save:

QUOTE

[SL_DVD_localrepo] Name=SL_DVD_localrepo $releasever $basearch local repository baseurl=file:///SL_DVD_localrepo enable=1

If you have other repos enabled and you want to use just the local repo you can do that with a command like:

CODE

yum install foo –disablerepo=* --enablerepo=SL_DVD_localrepo

or change “enable=1” to “enable=0” in all .repo files except SL_DVD_localrepo.repo


Hope this helps someone,

Thanks for this. Since many distros do this by default and I've been more familiar with them, this was most helpful.

Edit: I should clarify that "many distros" leave the CD/DVD enabled as a repo, but they don't create a local repo for it.

Great instructions, thanks. I found a number of non-working ones out there before yours. Yours worked for me for SL6.4 and RHEL6.4.

A couple improvements:
1. To turn off gpg checking for your local repo, allowing you to skip the "--nogpgcheck" argument when using yum, add this line to the /etc/yum.repos.d/SL_DVD_localrepo.repo file:

QUOTE

gpgcheck=0

2. Its nice to have 'yum grouplist' and 'yum groupinstall' working for a local repository. Here's how:

CODE

cd /SL_DVD_localrepo cp /media/\"ScientificLinux\ 6.4\ i386\ DVD\"/repodata/comps.xml . createrepo -g comps.xml . yum clean all yum makecache

Note: On RHEL, the file to copy is in a different directory. Look for the one named <huge random string>-comps-rhel6-Server.xml, e.g.:

CODE

cp /mnt/cdrom/Server/repodata/cda5429ve6f36ce1348e8f897f4fc96aa00d5727c75e9e5a0b5dc40d22a51116-comps-rhel6-Server.xml . createrepo -g cda5429ve6f36ce1348e8f897f4fc96aa00d5727c75e9e5a0b5dc40d22a51116-comps-rhel6-Server.xml .

Test it with:

CODE

yum grouplist
