Installing RHEL 8.x Server

STEP 1 : To start your installation of RHEL 8.1, highlight the “Install Red Hat Enterprise Linux 8.1” option and press enter. Your installation will now start.

If you have ran previous installations of Linux especially CentOS or Fedora, you will be very familiar with the installer. When the first screen appears, you can choose to test the installation media and proceed with the installation or directly proceed with the install.

STEP 2 : Select Installation Language

At this screen you will need to choose the language that you would like to use during your installation. In this example, “English”, “English (United States)” has been selected. Once you have made your selection, click on continue in the lower right hand corner of the screen.

STEP 3 : Installation Summary

At this screen various configuration options are available. Any option that is highlighted must be addressed before you can continue with your installation. It is from this screen that you can configure your Localization settings, Security Policy, Software and System settings.

STEP 4 : Time and Date

Starting with Localization, you can configure the keyboard language, language support and date and time zone on your system.

STEP 5 : Installation Destination

Once you have selected the option “Automatically Configure Partitioning”, click on the “Done” button in the upper left hand corner of the screen.

STEP 6 : Software Selection

In the software section you can choose what software to install, which package to be installed during the installation process. You can choose between few predefined options:

  • Minimal install
  • Custom operating system
  • Server
  • Workstation

Choose those per your need and select the packages that you wish to include by using the right section of the screen:

“Server with GUI” has been selected. Any additional “Add-Ons” that are available may be selected from the right hand options panel. In this example, no “Add-Ons” have been selected. Click “Done” to continue with your installation.

STEP 7 : Configure Network and Hostname

At this screen you can enter the “hostname to be used for your server and click on “Configure” to manually configure your network interface(s). To update the screen with the newly entered hostname, click on the “Apply” button. If you do not wish to assign a static IP address to your system and you wish to use “DHCP” for the automatic allocation of an IP address, then you can click on the “OFF/ON” box in the upper right hand corner of the screen.

In this example, we are going to assign a Static IP address. Generally all servers normally require a static IP address. This is an address that is assigned specifically to your server and will not change after a restart/reboot of your system.

Host name in this box enter a unique name to identify your system on your network. In this example, I have entered “rhel8”. Click “Apply” to update.

Click “Configure” to start configuring your network settings.

Next, you should see a “Pop-Up” menu where we are going to add our IP address, Netmask, Gateway and DNS server information. In the following example I will be using the following Network

STEP 8 :System Purpose

System Purpose is a new section for Red Hat Enterpirse Linux 8, you use System Purpose to record the intended use of a Red Hat Enterprise Linux 8 system. Setting System Purpose enables the entitlement server to auto-attach the most appropriate subscription. This section describes how to configure System Purpose using Kickstart.

In-depth system-level information for system administrators and business operations.
Reduced overhead when determining why a system was procured and its intended purpose.
Improved customer experience of Subscription Manager auto-attach as well as automated discovery and reconciliation of system usage.

If all installation preparations are completed, installation is started with the Begin Installation option.

STEP 9 : User Settings

The next section of this installation involves defining the root password and creating a new user. Click on each of the highlighted options in turn to enter the requested information. Whilst you are entering the requested details, the installation will continue in the background.

You must specify a root password to be used for the administration of your system. Note, if you supply a weak password, you will be asked to press “Done” twice to confirm you have chosen a weak password! The strength of your password is also indicated.

From this screen you must define the name of a user. In this example I have also chosen the user to be an “Administrator”. Again, if you supply a weak password, you will be asked to confirm this. Once you have supplied the relevant credentials, simply click “Done” to continue with the installation. It is strongly recommended that you use the “default” option of “Require a password to use this account“.

At this point your settings will now be displayed and installation will continue.

From this screen, you can register your system with Red Hat. You will not receive any updates without registration. I chose to register later in this setup. Now click “Finish” to continue and restart.

STEP 13 : RHEL 8 Login Screen
