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.

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

• 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.

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

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

[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
