Oracle Linux - How to Allow new users or existing user login via SSH

Applies to:
Oracle Linux 7 to Oracle Linux 9
Linux x86_64 on Oracle Public Cloud

Goal:
This document is intended to provide steps to allow new users or existing users(besides the default OPC user) login the instance via SSH using ssh-keys

Solution:
To allow new users log in to the instance with SSH-Keys, please follow the steps below:

• Create a new user (if needed):

$ sudo su -
#useradd -m -c "This is a Test User" test
#usermode -aG wheel test          <-- wheel group will allow this particular user to use sudo (this step can be skipped if no needed)
#passwd test
