Hello and welcome to todays video presentation on installing Oracle Linux 8
In this video we will cover the steps to install Oracle Linux 8.
So let’s get started.
To start the installation of Oracle Linux 8, you will first need to have the iso file
burned to a CD, DVD or copied to a USB stick.
Details to perform that task can be found in the Oracle Linux 8 Installation Documentation.
Most users today use the USB option and can create the media using the dd command on Linux
or macOS.
When using dd, make sure you correctly identify the source (if= option) and the destination
(of= option).
Getting these reversed or selecting the wrong destination can have adverse effects.
If creating the USB installer on a Windows PC, I personally use a tool called Etcher.
Etcher is a third party tool that is not provided or managed by Oracle and is mentioned here
as a convenience only.
Once you have the install media created, then boot your system using it as the boot source.
For this install, we will use the Oracle Linux 8 Update 1 media.
The system will boot to a text based screen showing Oracle Linux 8.1.0.
The options displayed are to Install Oracle Linux 8.1.0 or Test this media and Install.
If you are uncertain if your media is good, it is recommended to choose the Test this
media option.
The installer will validate the content on the media is good and then start the installer.
As I have used this media for other installs, I will just select Install Oracle Linux 8.1.0
and hit Enter key on the keyboard
Once the installer boot, we are presented with the Welcome to Oracle Linux 8.1 screen.
Here you will select your language for the installation process.
I will select English for both and click the Continue button.
On the next screen we will see the INSTALLATION SUMMARY.
The installer defaulted the localization details based on my system.
If necessary, click the Keyboard, Language Support, or Time & Date to change based on
your specific needs.
Under SOFTWARE, click the Software Selection icon.
The SOFTWARE SELECTION screen will appear.
Under Base Environment, Server with GUI is selected by default.
This provides you a Linux installation with the GNOME 3 graphical desktop.
The system will boot into this graphical desktop as a default using this option.
For this install, I will not be using a graphical desktop.
I choose to select Minimal Install and will add additional packages later using the DNF
package manager.
In the right side column we have Additional software for Selected Environment.
This is where you can select additional packages you want to add during the install.
Examples would be Basic Web Server or Development Tools.
If you are installing inside of VirtualBox, the Development Tools packages are beneficial
when you go to add the VBoxGuestAdditions.
Once you have made your selections, click the Done button in the upper left corner.
Under the SYSTEM column, now select Installation Destination.
On the INSTALLATION DESTINATION screen is where we will select which disk to write our
installation.
For this system, I have a single disk which is already selected.
If you want to customize your partitions layout, this can be done by selecting Custom under
the Storage Configuration section.
We will just use the default of Automatic in this demo.
When all the selections are made, click the Done button in the upper left corner.
Back on the summary screen, we now select Network and Host Name.
This will display all of the network interfaces detected by the installer in your system.
In my setup I have two network cards.
For this install I will be enabling the enp0s3 interface.
Ensure the interface is highlighted in the list and then toggle the switch on the right
side from off to on.
If the interface detects a DHCP server, it will automatically assign an ip address
If you want to provide a static address for your system, then click the Configure button
in the lower right.
For this demo we are going to stick with DHCP.
If you want to give you system a Host Name, you can now enter that in the lower left text
field.
For this demo, I will provide it a name of demo-ol8.example.com.
Once the name has been typed in, click the Apply button.
Review your information and then click the Done button in the upper left corner.
There are additional options which we are not going to cover, so review the Oracle Linux
8 documentation for more details.
Now that we have made the necessary selections click the Begin Installation button to start
the install.
While the install runs, the CONFIGURATION screen will display along with a progress
bar.
On this screen you can set your systems root password and create a user.
Under USER SETTINGS, click the Root Password.
Enter a secure password for your root user account and type it in the Root Password text
field.
Type the password again in the Confirm text field.
If your password is too weak, you will be prompted with a warning at the bottom of the
screen.
As this is a demo system that I plan to destroy, I will just accept the weak password by double
clicking the Done button to accept the password typed.
Back under USER SETTINGS, click the User Creation.
Enter the Full name, User name, and Password.
If you want this user to have admin privileges on the system using sudo, then check the box
Make this user administrator
Again, as this is a demo system that I plan to destroy, I will just accept the weak password
by double clicking the Done button to accept the password typed.
Back on the CONFIGURATION screen, once the install has finished copying files, click
the Finish configuration button in the lower right.
When that step completes, click the Reboot button in the lower right.
At this time the system will reboot.
If you did not remove your install media, the system will again boot to the text based
installer welcome screen.
If the install media was properly removed, the system will boot into your new Oracle
Linux 8 install.
Since I choose the Minimal (non-graphical) Install, the system boots into a console with
a simple login prompt.
The installation is complete.
At this time you can login with your root or user account created at install time.
In this video we walked through the basic steps to install Oracle Linux 8.
We covered the some of the different configuration options presented and one way to determine
at install time if you will install a graphical or non-graphical environment.
Thank you for watching and I hope you enjoyed this video.
