I created a droplet in ubuntu 16.04 following the following tutorial and it works like a charm: https://www.digitalocean.com/community/tutorials/how-to-install-hhvm-with-nginx-on-ubuntu-14-04. My goal is to create a shared hosting for my clients projects to replace my current Apache server with PHP-FPM running PHP 5.6 (they will not have access to the server). Searching I did not find a definitive way to isolate the execution of these websites in different users as it is traditionally done by PHP -FPM to increase security. Is this isolation necessary for this scenario? how to do this? Any help is very welcome. Thank you!
