Errors in the DO180 material, Chapter 2.1

[Tracy_Baker]

I've found a couple of mistakes in the Chapter 2.1 material for DO180. Both are minor, but we should be paying attention to the details.

----------

1: The command that is shown will not produce the output shown:

Change Hello! in the command to Hello world and you're good to go.

And, as I mentioned in another post, why is sudo being used?

----------

2: Why use sudo when the currently logged in user is root?

Again, root (or sudo) is probably not needed because a mariadb uses port 3306 by default.

Hi @Tracy_Baker ,

Thanks for your feedback.
These issues have been fixed in the latest version of DO180 (v4.6).

Thanks,
