====== Creating a Local Yum Repository Using an ISO Image ======

  * Transfer the removable storage to the system on which you want to create a local yum repository, and copy the DVD image (**V921569-01.iso**) to a directory (**/media/V921569-01.iso**) in a local file system. For transfer file can be used application WinSCP.

  * Create a suitable mount point, for example /mnt/OSimage/OL7.4_x86_64, and mount the DVD image on it.

<code bash>
# mkdir -p /mnt/OSimage/OL7.4_x86_64
# mount -o loop,ro /media/V921569-01.iso /mnt/OSimage/OL7.4_x86_64
</code>

  * **__Note__**
  * Include the read-only mount option (ro) to avoid changing the contents of the ISO by mistake.
  * Edit file /etc/fstab and add this row below,so that the system always mounts the DVD image after a reboot.

<code bash>
/media/V921569-01.iso /mnt/OSimage/OL7.4_x86_64 iso9660 loop,ro 0 0
</code>

  * Save and close file /etc/fstab
  * Create a new repository file containing these rows below (/etc/yum.repos.d/OL74.repo).

<code bash>
[OL74]
name=Oracle Linux 7.4 x86_64
baseurl=file:///mnt/OSimage/OL7.4_x86_64
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY
gpgcheck=0 
enabled=1
</code>
 
Clean up the yum cache.

<code bash>
# yum clean all
</code>

Test that you can use yum to access the repository.

<code bash>
# yum repolist
Loaded plugins: refresh-packagekit, security
...
repo id                          repo name                                status
OL74                             Oracle Linux 7.4 x86_64                  25,459
repolist: 25,459
