Install Oracle Linux 8.5.0

During install do not use scaled mode because it can cause problems with the GUI. CTRL+C will exit scaled mode if enabled (CTRL+ALT will return you to the desktop).

Setup as follows:

• Select language: English (United Kingdom)
• Time & Date: Etc → Coordinated Universal Time
• Software Selection: Server → Headless management, system tools
• Installation Destination: X, automatic partitioning
• Network and Host: ON → hostname.kewl.org
• Root Password

Begin installation… Reboot System

$ ssh root@hostname.kewl.org

$ yum update
Y
$ reboot

Install the VBox Linux Additions so we can mount a share on the VM. This is to access downloaded files on the host machine with a shared folder.

$ yum install kernel-uek kernel-uek-devel make perl
Y
$ reboot

$ uname -a
Linux hostname.kewl.org 5.4.17-2136.307.3.1.el8uek.x86_64 #2 SMP Mon May 9 17:29:47 PDT 2022 x86_64 x86_64 x86_64 GNU/Linux
$ mount /dev/sr0 /mnt
$ /mnt/VBoxLinuxAdditions.run

Oracle Database Server version 21c.

Install guide

The install guide is mostly for the ZIP version but we shall install the RPM for OL8.

The O/S needs to be setup for Oracle, a preinstall RPM does this automatically for us.

Preinstall RPM

$ yum install ./oracle-database-preinstall-21c-1.0-1.el8.x86_64.rpm
Y
$ reboot

Now we can install the Database Server and afterward configure it with the example database.

Install RPM

$ yum install ./oracle-database-ee-21c-1.0-1.ol8.x86_64.rpm
Y
