Chapter 1. Installing RHEL 8

You can install RHEL 8 in interactive mode or you can perform an unattended installation using Kickstart. This document explains how to perform an interactive installation.

For Kickstart installation, use Server as your base environment and take into account the recommendations from the SAP HANA Storage Requirements. For a test system, you can remove the default /home file system allocation and use a large root (/) file system.
