Installing RHEL 7 Guide

Installing RHEL 7


Red Hat Enterprise Linux (RHEL) is a Linux operating system developed by Red Hat. RHEL is mainly aimed at commercial organisations. Red Hat Enterprise Linux is available for multiple platforms including x86, x86_64, PowerPC, IBM pSeries and IBM System z (Mainframe). RHEL is probably one of the most popular Linux Operating system used by large Enterprises. RHEL can be downloaded from Red Hat as an evaluation giving you a free 30 day trial.

To Download an evaluation copy of RHEL 7, simply follow the link and follow the instructions:

Evaluation copy of RHEL 7

In this installation guide I have chosen the "X86_64" (64 bit) version.



Once you have downloaded your chosen version of RHEL7, you will need to burn this iso image to a DVD. For software that can do this, search for "dvd iso burning software" in the search box located above. Your PC/system may already have DVD burning software installed such as "Brasero, K3B, Nero, CDBurnerXP or Roxio". Once you have burned your "iso" image of RHEL 7 to a DVD, you will need to leave the DVD in the DVD drive and reboot your system. (This example assumes you are using a x86_64 version of the software). 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 a message indicating which key needs to be pressed. Once you have access to your BIOS settings, you will need to modify the boot order of your system to boot from CD/DVD first. Once you have made this change, you can reboot your system and follow the tutorial below.

Kdump


Kdump is a Kernel crash dumping mechanism that is used to help diagnose serious issues. For the purposes of this tutorial, I have chosen not to "Enable" kdump. Unfortunately, this requires a quick reboot. You will receive a message "Changing kdump settings requires rebooting the system to reallocate memory accordingly. Would you like to continue with this change and reboot the system after first boot is complete?" Choose "YES" to continue.
