[FIXED] Why should I add new user to Ubuntu before deploying web apps?

Issue

I’m studying deploying rails app and all tutorials add new user before starting. Why should I add new user rather than just using root?

Reference https://gorails.com/deploy/ubuntu/16.04

Solution

This is done for security, basically root user can do anything so it's risky.

"The root user is the administrative user in a Linux environment that has very broad privileges. Because of the heightened privileges of the root account, you are actually discouraged from using it on a regular basis. This is because part of the power inherent with the root account is the ability to make very destructive changes, even by accident."
