I am sure there is a guide somewhere on this site that is helpful to a point, but they're vague. No problem there, trying to make them accessible and malleable, but on another page regarding subdomains, Kamal said, "Make sure that DNS is properly setup and restart Apache and you should be good to go."
Now, I understand copying the domain.com file to sub.domain.com in sites-available, then running sudo a2ensite sub.domain.com and then restarting apache.
But as far as the DNS goes...give it to me straight. Do I:
1. Create a new domain record set under DNS in the control panel that is sub.domain.com, with an A record of @ , xx.xx.xx.xx ? Or,
2. In the already existing DNS record for domain.com, simply add another A record of sub.domain.com , xx.xx.xx.xx? Or,
3. Is there another way of doing this?
The site is enabled, but I'm not sure "how to setup the DNS properly".
Thanks very much in advance!
