I need to setup a second machine for whmcs since whmcs likes to XSS all over the machine. However I am curious how would is setup this second machine to have it's own LAMP stack that would respond to web2.etc-md.com? I need this so whmcs will run on this second machine. I would also like let's encrypt to get a valid cert for this but i think there's a complication there. let's encrypt fails even though I have dns on the primary machine pointing to the new machine. Any ideas? I have a separate virt pro license i purchased for this second machine.
