LEMP on DigitalOcean with Wordpress, blackjack and multisite?

Question

ubuntu

Tell me how to set up LEMP in a DO droplet in a relatively secure and productive way? I'm not an admin, but I'm ready to sit a little and study the issue to do "the right way."
Here are the inputs.
Necessary:

• Multiple sites on a droplet (vhost)
  
• Despite Nginx having normal SEF URLs
  
• Multisite Wordpress will be used
  
• SSH and SFTP only, keyed access
  
• Differentiation of access to sites / users through chroot
  

What is supposed to be installed:

• Ubuntu Server 14.04 (now there is a server on Debian, but they say about ubuntu in a simpler way)
  
• nginx (no apache in backend)
  
• MariaDB 10 (or Percona, I don't really see a difference for my use case)
  
• php-fpm
  

I partially found scattered manuals on how to set up individual components, but maybe a silver (or silver-plated) bullet has already been cast for this case?
It is also not entirely clear how exactly DigitalOcean will make this task easier or harder? I would be grateful for tips and tutorials on the topic.

Everything is simple to indecent. Reliable and functional system. Minus - it is installed only on Debian 6/7 and Ubuntu 12.04/14.04, although you can modify the installer script if you wish.
