Phoenix Server
If you've completed the steps in Server Boilerplate, you're ready to start building the Phoenix app server. We'll use nginx to handle SSL and reverse proxy to the running application. You might be surprised to see that neither Erlang or Elixir are installed on this machine! The build server (covered in the next chapter) will package Erlang, Elixir, and everything else that is needed.
Don't forget DNS
At this point you should know your machine's IP. Now is a good time to make any DNS changes if you haven't already. These will need to be in place later when you set up SSL with Let's Encrypt.
If you need extra servers, repeat this chapter and make changes as necessary.
Log in to one of the servers you've provisioned with your admin user and proceed.
