I have two cloud hosted LAMP servers that I’d like to encrypt. I found this how-to about adding LetsEncrypt certs to this OS. Do any of you have any recommendations beyond what the link says? Also one of them is currently serving to a non-standard port, am I right assuming I should change that back to 80 before adding the cert?
I would setup HTTPS redirect for traffic coming into port 80. Most people use port 443 for encrypted traffic, but you could use something else and redirect to that port. This is where your cert will be utilized.
