[OT] Next steps in using DigitalOcean to host a website running Mojolicious

Aldebaran has asked for the wisdom of the Perl Monks concerning the following question:

I've never had a VPS before a fortnight ago, so I have yet to figure out much of the functionality. Also not sure how much of my question is vendor-specific. I've gotten so far as to get my domain out out the registrar's (ionos') purgatory and have the nameservers pointing to DO. Then, I sit there looking at the records page and wonder if I have more to do there...or not. (can't share the page.)

It has a table with these values along the top:


    A
    AAAA
    CNAME
    MX
    TXT
    NS
    SRV
    CAA
[download]

This is the explanation for A:

Use @ to create the record at the root of the domain or enter a hostname to create it elsewhere. A records are for IPv4 addresses only and tell a request where your domain should direct to.

Do I fiddle with this menu, creating a 'record', or do I get what I need by creating-apache-virtual-hosts-on-ubuntu? I've done this before to my home machine, but to put it bluntly, do I need to create a virtual host on a virtual host?

I've been looking at the host command to see if it tells me anything relevant:

$ host -t soa www.merrillpjensen.com
www.merrillpjensen.com has SOA record ns1.digitalocean.com. hostmaster
+.www.merrillpjensen.com. 1601009638 10800 3600 604800 1800

The meaning of Start of Authority data seems to deal with varying measures of time. (1601009638 doesn't make sense to me as the first four numbers are to represent YYYY, and nothing happened in 1601 except that life was nasty, brutish, and short.)

My goal for this thread is to get "hello mojo world" to display. I'd like to know whether I'm doing the right thing before I do the next thing.

Thank you for your comment,
