1.9 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 https://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
```
Disable all existing yum repositories.
In the /etc/yum.repos.d directory, edit any existing repository files and disable all entries by setting enabled=0. If you have the yum-utils package installed, as described in Section 1.3.4, “Using Yum Utilities to Manage Configuration”, you can disable all repositories by running:
```
# yum-config-manager --disable \*
```

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
