How would I use yum to update or install packages from a ISO of Red Hat Enterprise Linux version 5

Resolution:

In order to use yum to install or update packages from an iso file, follow the steps below: -

1. Create directories to mount the iso file.

   
   #mkdir -p /cdrom/iso
   

2. Mount the iso as loopback device.

   
   #mount -o loop  /cdrom/iso
   

   Replace with the iso file.

3. Create a repository. The createrepo package needs to be installed on the system in order to run the following commands. createrepo is an optional package and is not installed by default.

   
   #cd /cdrom
   #createrepo .
   #yum clean all
   

4. Create a file /etc/yum.repos.d/file.repo as follows:

   
   #cat /etc/yum.repos.d/file.repo
   [RHEL 5 Repository]
   baseurl=file:///cdrom
   enabled=1
   

Running yum should now work with the iso file as the source.
