Create a WordPress site Using EC2 and Amazon RDS

In this article, I am going to demonstrate on how you create a WordPress site using EC2 and MySQL RDS Database Instance.

Amazon Relational Database Service (Amazon RDS) allows users to easily create, operate, and scale a relational database in the cloud. We are going to create an RDS database, install a web server and configure WordPress to connect to the RDS database. We will then run the final configuration through the web browser to complete the installation of wordpress site.

Please visit my GitHub Repository for RDS_projects on various topics being updated on constant basis.

Let’s get started!

Objectives:

1. Create EC2 Security Group – Web-Access

2. Create RDS Security Group – RDS-SG

3. Create an EC2 webserver

4. Create RDS Database

5. Complete WordPress Installation and Test

Pre-requisites:

AWS user account with admin access, not a root account.
