Creating a Local Yum Repository Using an ISO Image

Note The system must have sufficient storage space to host a full Oracle Linux Media Pack DVD image (approximately 3.5 GB for Oracle Linux Release 6 Update 3).

To create a local yum repository (for example, if a system does not have Internet access):

• On a system with Internet access, download a full Oracle Linux DVD image from the Oracle Software Delivery Cloud at http://edelivery.oracle.com/linux onto removable storage (such as a USB memory stick). For example, V33411-01.iso contains the Oracle Linux Release 6 Update 3 Media Pack for x86 (64 bit).

• Note
• You can verify that the ISO was copied correctly by comparing its checksum with the digest value that is listed on edelivery.oracle.com, for example:

# sha1sum V33411-01.iso
7daae91cc0437f6a98a4359ad9706d678a9f19de V33411-01.iso

• Transfer the removable storage to the system on which you want to create a local yum repository, and copy the DVD image to a directory in a local file system.

# cp /media/USB_stick/V33411-01.iso /ISOs

• Create a suitable mount point, for example /var/OSimage/OL6.3_x86_64, and mount the DVD image on it.

# mkdir -p /var/OSimage/OL6.3_x86_64
# mount -o loop,ro /ISOs/V33411-01.iso /var/OSimage/OL6.3_x86_64

• Note
• Include the read-only mount option (ro) to avoid changing the contents of the ISO by mistake.

• Create an entry in /etc/fstab so that the system always mounts the DVD image after a reboot.

/ISOs/V33411-01.iso /var/OSimage/OL6.3_x86_64 iso9660 loop,ro 0 0

In the /etc/yum.repos.d directory, edit the existing repository files, such as public-yum-ol6.repo or ULN-base.repo, and disable all entries by setting enabled=0.

• Create the following entries in a new repository file (for example, /etc/yum.repos.d/OL63.repo).

[OL63]
name=Oracle Linux 6.3 x86_64
baseurl=file:///var/OSimage/OL6.3_x86_64
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY
gpgcheck=1 
enabled=1

Clean up the yum cache.

# yum clean all

Test that you can use yum to access the repository.

# yum repolist
