Linux Superuser: RHEL 6 Installation

In my last post I explain the steps for installation of Redhat Enterprise Linux 6. In this post I will explain the Post installation Steps, which are required to complete your installation. Since this is an important objective for RHCSA, understanding all the installation steps is a must.

After package installation reboot your system and from there you have to follow the post installation steps:
Step 1. After rebooting welcome screen appears, click forward button for the next step.

Step 2. In License Information screen click on "yes, I agree to License Agreement" and click forward.

Step 3. Then do the software update process. But to do that you should have a subscription from Red Hat Network(RHN). And click forward to continue.

Step 4. Next screen allows you to create a regular USER. Provide username, full name and password and click forward to continue.

Step 5. In the Date and Time setup wizard enter the date and time and click forward to continue.

Step 6. In the next screen you can setup a KDump environment. It is up to you to setup a KDump environment.

KDump is a Kernel Crash Dumping Mechanism it will prevent you from kernel crash. It is recommended to setup a KDump environment.

After setting-up the KDump environment you are now ready to login to the RHEL 6 server..

To learn Red Hat Enterprise Linux 6 first of all you have to know about the installation process and how to install the all new Red Hat Enterprise Linux 6. Here I will explain the step-by-step process of installation of RHEL 6.

Installation of RHEL 6 is one of the objectives of RHCSA and RHCE certification from Red Hat. It is directed that one should know at least the graphical based installation of RHEL 6.

First of all you have to obtain the DVD/CDs’ or the RHEL6 DVD.iso.

There are several methods of installing RHEL 6 like: installation from DVD, installation form Hard Drive, Network Installation, Installing via NFS, FTP or HTTP. Steps followed in all the process are same except the media selection from which you will install RHEL 6. I will explain the installation from Local Hard Drive using the Rescue disk (Which can also downloaded from Red Hat website), and the RHEL 6.iso.

Step 1. Extract the folder “images” from the RHEL 6 DVD. Since the image folder contains the product.img file which is used to start the installation and bring up the anaconda to start installation process.

Step 2. Make a folder from where you want to install Red Hat Enterprise Linux 6 and in it paste the “RHEL 6 DVD.iso” file and the “images folder “ which you have extracted in the above step.

I had created the folder in the E: drive of my computer like E:\RHEL6\ and paste the “RHEL 6 DVD.iso” file and the “images folder “ in it. But at the time of installation you have to give the complete path of the “.iso“ image like the hard disk and partition number like “/dev/sdb5/RHEL6/”.

Step 3. Reboot the System and boot form the rescue disk by selecting boot form CD/DVD from the boot menu. After booting form rescue disk you will see the graphical boot menu.

Step 4. There are four options in the menu : 1. Install or upgrade existing systems, 2. Install system with basic video drivers,3. Rescue installed system, 4. Boot from local drive.

Select the first option “Install or Upgrade Existing System”.

Step5. Select language and click ok.

Step 6. Select installation method : Local CD/DVD and click ok.

Step 7. Select partition and determine full path of the folder containing RHEL 6 DVD.iso. In my case the partition is “/dev/sdb5” and the path is “/Operating System/RHEL6/ISO”.

Step 8. Welcome screen appears click next to continue.

Step 9. Select Installation Language and Keyboard Type.

Step 10. Select type of storage device. If you are confused in between select the Basic Storage Devices.

Step 11. Time Zone Configuration window. Select time and click next to continue.

Step 12. Set Root password and click next.

Step 13. Assign storage device from the box on the left side and send it to the box in right. I have to install RHEL 6 in my 80 Gb sata HDD so I seletct the second HDD and move it to right box (Install Target Devices).

Step 14. In the next step you have to select how you want to use your HDD to install RHEL 6. I prefer to make file systems manually, so I selected create custom layout.

Select the free space in the HDD (and if no free space is there you have to delete some partitions to create free space.) and click on Create. A dialog box open select the Standard Partition and click next.
