MySQL is used to allow storage and retrieval of structured data. SQL is used by countless services for all kinds of use cases.

You may remember setting up MySQL from OPS235 - we're doing the nearly identical thing here.

Note that MySQL has two root passwords - one for localhost and one for external requests. Just run the two commands you're given in the log. Use a password you make up yourself, but don't use a secret password - you'll be putting it in a plain text file later.

We'll install Roundcube Mail. Download the tarball from their website directly into the html directory of your vm4 using wget. This part may take some effort depending on the Sourceforge website.
