Download RHEL 8 ISO Image
To prepare your installation media, you will need to download the installation image for your system architecture. To do this, you will need to signup for a free trial at RedHat’s website.
Note that we do not stop explicitly on how to create your boot media as this is a topic of another conversation and the process might be different, depending from what OS you are using. Still, you can burn the ISO to a DVD or prepare a bootable USB drive using these 3 GUI-Enabled USB Image Writer Tools.
Installation of RHEL 8
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.
The second screen asks you to choose the preferred language:
Next comes the configuration screen, that allows you to choose between the following options:
Starting with Localization, you can configure the keyboard language, language support and date and time zone on your system.
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
Choose those per your need and select the packages that you wish to include by using the right section of the screen:
Click on “Done” button. Proceed with the “System” section. There you will be able to partition your drives and select installation destination.
For the purpose of this tutorial I have chosen the “automatic” storage configuration option, but if you are configuring this for a production server, you should partition the drive per your specific needs.
In the network section, you can configure the system hostname and NIC.
To adjust the network interface settings, click on the “Configure” button.
Next under “Security” you can choose the security policy for your system. To help you with the choice, you can check additional information about RHEL 8 security in the RedHat portal.
When you are ready, you can click done and begin the installation. During the installation process, you will be asked to configure the root user’s password.
When the installation process is ready, you will boot into your new RHEL 8 installation.
