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.

Step 1: Server Credentials

This assumes you are now connected to the server via SSH.

• sudo -s Enter root mode for admin access
• groupadd devgroup Create new group to be later granted access to /var/www/html

Creating a new Root User

• useradd -G root,devgroup masterdev Create new root user. Also add to the devgroup
• passwd masterdev Change password for the new root user
• At this point, you'll need to input your new root user's new password
