Set-up WordPress on aws with EC2 and Amazon RDS (Step-by-Step)

WordPress with EC2 and Amazon RDS

There are a lot of websites on the internet, still, people want to create more. A lot of methods are also available for creating them, WordPress is one of them, or we can say “it is the popular one“. So, today we are going to learn about “Set-up WordPress on aws with EC2 and Amazon RDS“.

Before going further, let us understand about “WordPress“, “what is it, how it works, what are its key components“:

It is written in “PHP Programming Language“, which is used for web development, especially for back-end related tasks. Now, say you have written something in “HTML + CSS + PHP” and named the file as “test.php“, then there are two things possible:

  1. All the “CSS + HTML + PHP” code is in the single “test.php” file
  2. All the “CSS, HTML, PHP” code is written in separate files, say “test.css“, “test.html“, “test.php

As of now, all the things combined only creates “Static Pages“, but what if we want some functionality like -> “User is asked to provide some details, and after submitting them, a new page should be provided to the user

In that case, we need “a Database (MySQL)” where we can store the submitted details and then process those details, in return after processing we will provide a new page.

So, now we have a total of 4 components:


Now that we know what components make the basic functionality of “WordPress“, it is time to look up how we can “set-up WordPress on aws with EC2 and Amazon RDS

So, we have divided the deployment in two “AWS Services“:

  1. Amazon EC2 = For storing the “WordPress Code
  2. Amazon RDS =  For storing the “Database

So, the following post is going to be “divided” into two steps:

  • Step 1 = Specifying how to place the WordPress Code on Amazon EC2 Instance
  • Step 2 = How to create an “Amazon RDS” database instance

Step 1: Create an EC2 instance

We have skipped a few steps before one shown in the screenshot below if you are completely new to “Amazon AWS” and do not even know how EC2 instances are created on AWS, then follow the following post -> How to create an EC2 instance

Configure Instance

In this, we are using a “Bootstrap script” for creating the “EC2 instance“, to learn more about it, follow -> How To Use Bootstrap Scripts With EC2 Instance 

Create an EC2 Instance with bootstrap script
Create an EC2 Instance with a bootstrap script

Line 1 = #!/bin/bash
Line 2 = sudo apt update -y && sudo apt install -y nginx && sudo apt install -y php-fpm php-mysql
Line 3 = wget
Line 4 = sudo cp default.conf /etc/nginx/sites-available/wordpress
Line 5 = sudo ln -s /etc/nginx/sites-available/wordpress /etc/nginx/sites-enabled/
Line 6 = sudo unlink /etc/nginx/sites-enabled/default
Line 7 = cd /tmp
Line 8 = curl -LO
Line 9 = tar xzvf latest.tar.gz
Line 10 = sudo cp -a /tmp/wordpress/. /var/www/html
Line 11 = sudo chown -R www-data:www-data /var/www/html
Line 12 = sudo systemctl restart php7.2-fpm
Line 13 = sudo systemctl reload nginx

Explanation of the code/script used as a bootstrap above:

Line 1 = It tells that this script should always run with “bash shell

Line 2 = Update the server/system and then install “nginx“, “php-fpm“, “php-mysql

Line 3 = Download a preconfigured “default.conf” file for “nginx” (we have created this for much smoother deployment and automation)

Line 4 = Copy the downloaded “default.conf” to specific directory, and rename as “wordpress

Line 5 = Create a “symbolic link” of “wordpress” configuration file, inside the “/etc/nginx/sites-enabled/” directory

Line 6 = Unlink the “Old” configuration file

Line 7 = Change the current directory to “/tmp” directory

Line 8 = Download the latest version of “wordpress” using the “curl” command

Line 9 = Extract the downloaded wordpress package using the “tar” command

Line 10 = Copy all the extracted contents to the main nginx root directory “/var/www/html

Line 11 = Change the ownership of “/var/www/html” recursively to “www-data“, under this user, the nginx server operates

Line 12 = Restart the “php7.2-fpm” service, this handles all the dynamic content of php

Line 13 = Finally, reload the “nginx” web server

Configure Security Group

Also, we have to create a security group, as shown below, the security group has the following “inbound rules“:

  • HTTP = TCP = 80 =
  • HTTP = TCP = 80 = ::/0
  • SSH = TCP = 22 =

After creating the “EC2 instance” with the settings specified above, copy the “IP Address” that instance and paste it into the “browser” as shown below.

During the “set-up“, you will be shown a screen similar to the one shown below and asked for the details.

These are the details for the “Database“, as of now we have no database created, so we have to create one and we are going to create a database on “Amazon RDS“.

Step 2: Create an Amazon RDS database Instance

Before going further, make sure you read -> Create an MYSQL Database on Amazon RDS

Connectivity & Security

We have to note the “Endpoint” of the “Amazon RDS” instance, as shown below.

This is going to be used as the connector point to the “MySQL” from the “WordPress“.

Copy Endpoint of RDS instance

After noting the details from above, we have to provide them on the following screen:

  • Database Name = The name that you have used during the “Amazon RDS” instance creation
  • Username = The name of the database user
  • Password = Password for the database
  • Database Host = This is where we have to specify the “Endpoint” of our “Amazon RDS” instance
  • Table Prefix = What prefix do your database tables should have

After providing all the details, click on the “Submit” button.

Step 3: Allow traffic from “EC2 Instance” to “Amazon RDS Instance”

Now, this is the last step of the post. In this, we have to create an inbound rule for the “Amazon RDS” security group, which allows the traffic coming from “EC2 instance created in Step 1” to “Amazon RDS instance created in Step 2“.

Add EC2 security group as source for RDS security group

Note: Make sure you “allow traffic from EC2 instance to RDS instance” before clicking on the “Run the installation” button as shown in the screenshot below.

WordPress “Welcome Screen”

Now that our WordPress is set-up completely, it is time to install it, as shown below.

After filling up all the details, click on the “Install WordPress” button.

Provide the information needed

And after that, you will be seeing a screen similar to the one shown below, click on “Login“.

WordPress has been successfully installed

You will be prompted to the “Login” screen, here you can provide your credentials and access the “WordPress Dashboard“.
