1.2 Obtaining and Preparing Installation Media

The Oracle Linux distribution is free to download, use and distribute.

You can download the Oracle Linux installation media from the Oracle Software Delivery Cloud at
https://edelivery.oracle.com/linux. After you have logged in, select the Linux/OVM/VMs check box, then select Oracle Linux as the Product and x86 64 bit as the Platform. Click Continue to search and then select the Media Pack for your Oracle Linux 7 release.

The Media Pack contains the following ISO images:

  • Oracle Linux 7 for x86_64 (64 bit)

    This ISO image contains everything needed to boot a system and install Oracle Linux.

  • Oracle Linux 7 Boot ISO image for x86_64 (64 bit)

    This ISO image contains everything that is required to boot a system and start an installation. However, to complete the installation, you must specify the location of the packages, for example on a local disk or an NFS share. RHCK is used during the installation and both UEK and RHCK kernels are installed. After the installation, the system boots the UEK kernel by default.

    Note

    When installing releases prior to Oracle Linux 7 Update 3, Unbreakable Enterprise Kernel Release 3 is used. From Oracle Linux 7 Update 3 on, the default kernel is Unbreakable Enterprise Kernel Release 4.

  • Oracle Linux 7 UEK Boot ISO image for x86_64 (64 bit)

    This ISO image contains everything that is required to boot a system and start an installation. However, to complete the installation, you must specify the location of the packages, for example on a local disk or an NFS share. UEK is used during the installation and is the default kernel that is booted after an installation. Use this boot image if you have hardware that is only supported on UEK, or if you are having trouble with the installer when using the RHCK boot image. This ISO image is available in the Media Pack for Oracle Linux 7 Update 2 and later.

  • Oracle Linux 7 Source DVD 1 and 2

    These ISO images contain the source code for the software packages in the release.

You can use the full installation ISO image or the boot ISO image to do the following:

The ISO images can be used in a virtual DVD-ROM drive to boot and install an Oracle VM or Oracle VM VirtualBox virtual machine (guest).

You can use the full installation ISO image to prepare a network location, such as an NFS share or HTTP server directory, for use during an installation. This method is typically used when a boot image is used to start an installation. See Section 1.3, “Configuring a Network Installation Server”.

Note that the media pack might contain additional content that may pertain to a particular release update of Oracle Linux. Items such as Driver Update Disks may also be included. These items are described in further detail in the release notes for the particular update release.

After installation, you can obtain Oracle Linux packages from the Unbreakable Linux Network (ULN) and the Oracle Linux yum server. For more information, see Chapter 5, Post-Installation Configuration.
