Setting up a WordPress site on AWS

This tutorial walks through setting up AWS infrastructure for WordPress, starting at creating an AWS account. We'll manually provision a single EC2 instance (i.e an AWS virtual machine) to run WordPress using Nginx, PHP-FPM, and MySQL.

This tutorial assumes you're relatively comfortable on the command line and editing system configuration files. It is intended for folks who want a high-level of control and understanding of their infrastructure. It will take about half an hour if you don't Google away at some point.

If you experience any difficulties or have any feedback, leave a comment. 🐬

Coming soon: I'll write another tutorial on a high availability setup for WordPress on AWS, including load-balancing multiple application servers in an auto-scaling group and utilizing RDS.

	After automatically updating Postgres to 10.0 via Homebrew, the pg_ctl start command didn't work.
	The error was "The data directory was initialized by PostgreSQL version 9.6, which is not compatible with this version 10.0."

	Database files have to be updated before starting the server, here are the steps that had to be followed:

	# need to have both 9.6.x and latest 10.0 installed, and keep 10.0 as default
	brew unlink postgresql
	brew install [email protected]
	brew unlink [email protected]
	brew link postgresql

	1. Highlight a recommended option,
	2. Allow users to switch currency (€/$/£)

	9. Sell benefits instead of features
	10. Indicate that users can cancel any time

	I'm writting this gist for anyone who is having problems updating their OVH Public Cloud hostname on CentOS 7

	The issue:

	When ordering a public cloud instance and setting the instance name to sub.domain.tld and then eventually changing that sub
	the settings don't seem to update on OVH side.

	It looks like systemd-hostnamed still pulls the original hostname from what i'm guessing is the datastore on OpenStack. (unconfirmed)

	The solution:
