This tutorial will guide you through your very first configuration of an SSL website with Let’s Encrypt certification. Let’s Encrypt is a new SSL authority that provides free SSL certificates. We are going to use two existing tutorials (“How to setup an intermediate compatible SSL website with Let’s Encrypt certificate” and “The Perfect Server – Ubuntu 15.10 (Wily Werewolf) with Apache, PHP, MySQL, PureFTPD, BIND, Postfix, Dovecot and ISPConfig 3”).
The setup described here is compatible with any Ubuntu LAMP server, so you can use this one as the basis setup too.
This tutorial will show you how to setup Let’s Encrypt on Servers without ISPConfig 3 as there will be a direct implementation of the Let’s Encrypt service in the next ISPConfig 3 release (version 3.1) soon. So if you plan to use ISPConfig, wait for the 3.1 release and also a new tutorial.
