Installing Oracle Linux 7

Installing Oracle Linux 7

Oracle Linux 7, previously known as Oracle Enterprise Linux, is a distribution based on Red Hat Enterprise Linux. Like other RHEL based distributions, Oracle's Linux is repackaged and branded and distributed freely under the GNU General Public License (GPL). Updates are available via the public repositories, however, official support from Oracle will come at a cost. Oracle Linux 7 features XFS as its default filesystem giving the potential for filesystems with a maximum size of 500TB (Terabytes) and a maximum file size of 16TB. Oracle Linux also supports the Btrfs filesystem, Linux Containers, ksplice, DTrace, Xen enhancements, and OpenStack cloud support. Two kernels are available: "Red Hat Compatible Kernel" which is identical to the kernel that is shipped with Red Hat Enterprise Linux (RHEL) and Oracle's Unbreakable Enterprise Kernel (UEK). Oracle Linux 7 is available from Oracle's E delivery service and also various mirror sites. To download from Oracle's E Delivery service you must register first.

To install Oracle Linux 7 simply follow the instructions below:

Once you have downloaded your Oracle Linux iso image, you will need to burn this to a blank DVD. For software that can do this, simply search for "dvd iso burning software" in the search box located towards the top of this page. Your computer probably has CD/DVD burning software installed such as "Brasero, K3B, Nero, CDBurnerXP or Roxio". Once you have burned your "iso" image of Oracle Linux 7 to your DVD, you will need to place the DVD in the drive of the computer you are going to carry out the installation on. Once the disk has been loaded, simply reboot your system. As your computer reboots, you will need to press the appropriate key to access your system's BIOS settings. On many systems this key will be "F8", "F11" or "F12". Most systems will display the a message indicating which key needs to be pressed. Once you have access to your BIOS settings, you will need to modify the boot sequence order of your system to boot from CD/DVD first. Once you have made this change, you can reboot your system and follow the instructions below.

From this menu, we are going to configure the network and give our system a name (hostname). If your system is connected to your network, you can simply select the "On" position to connect to your network.
