OCI: Add sudo root Permissions to Regular Linux User in Oracle Linux

Applies to

Oracle Cloud Infrastructure - Version N/A and later

Oracle Linux x86-64

 

Goal

There is a need for an additional regular user (testuser in this example) to be able to sudo to the root user, in a Oracle Linux OCI instance based on a standard Oracle Linux Platform image.

In simpler terms, there is a need for a separate user to use sudo just like the default opc user.

 

Solution

The below solution uses the existing sudoers configuration file for the opc user as a “template”, creates a copy of that file and modifies the new file to apply to the new user.
