You should have a domain name registered with a domain registrar. Access to your domain’s DNS management is also essential for configuring DNS records.
Basic Familiarity with AWS Services
While this guide will walk you through the setup process, having some basic knowledge of AWS services like EC2, RDS, and S3 can be helpful.
3. Setting Up AWS Infrastructure
Let’s get started with the AWS infrastructure setup for your WordPress site:
Launching an EC2 Instance
Amazon Elastic Compute Cloud (EC2) is a web service that provides resizable compute capacity in the cloud. This is where your WordPress website will be hosted.
- Log in to your AWS Management Console.
- Navigate to the EC2 dashboard.
- Click “Launch Instance” to create a new EC2 instance.
- Choose an Amazon Machine Image (AMI) based on your requirements (e.g., Amazon Linux, Ubuntu, or WordPress-optimized AMIs).
- Select an instance type based on your expected traffic and workload.
- Configure instance details, including network settings, security groups, and IAM roles.
- Review and launch the instance.
- Create or choose an existing key pair to securely connect to your EC2 instance.
Security Group Configuration
A security group acts as a virtual firewall for your EC2 instance. It controls inbound and outbound traffic. You need to configure the security group to allow HTTP and HTTPS traffic.
- In the EC2 dashboard, select your instance.
- Under the “Security groups” tab, click “Edit inbound rules.”
- Add rules to allow incoming traffic on ports 80 (HTTP) and 443 (HTTPS).
Elastic IP Address Allocation
Elastic IP addresses are static public IP addresses that you can associate with your EC2 instances. This ensures your website’s IP address remains consistent.
- In the EC2 dashboard, navigate to “Elastic IPs.”
- Allocate a new Elastic IP address and associate it with your EC2 instance.
4. Installing LAMP Stack on AWS
A LAMP stack (Linux, Apache, MySQL, PHP) is the foundation for hosting WordPress. Let’s set it up:
Installing Apache
- Connect to your EC2 instance using SSH.
- Update the package list:
sudo yum update -y
- Install Apache:
sudo yum install httpd -y
- Start the Apache service:
sudo systemctl start httpd
- Enable Apache to start on boot:
sudo systemctl enable httpd
Installing MySQL
- Install MySQL:
sudo yum install mysql-server -y
- Start the MySQL service:
sudo systemctl start mysqld
- Secure your MySQL installation:
sudo mysql_secure_installation
- Follow the prompts to set a root password and configure security options.
Installing PHP
- Install PHP and required modules:
sudo yum install php php-mysql -y
- Restart Apache to apply changes:
sudo systemctl restart httpd
With the LAMP stack in place, your server is ready to host WordPress.
5. Creating a MySQL Database for WordPress
WordPress relies on a MySQL database to store its data. Let’s set up a database:
Setting up the Database
- Log in to your MySQL server:
mysql -u root -p
- Enter the root password.
- Create a new database for WordPress:
CREATE DATABASE wordpress;
- Create a user for the database:
CREATE USER 'wordpressuser'@'localhost' IDENTIFIED BY 'your_password';
- Grant privileges to the user for the WordPress database:
GRANT ALL PRIVILEGES ON wordpress.* TO 'wordpressuser'@'localhost';
- Flush privileges to apply changes:
FLUSH PRIVILEGES;
- Exit MySQL:
exit
6. Configuring
WordPress
Now, let’s configure WordPress to run on your AWS instance:
Downloading WordPress
- Navigate to your web directory:
cd /var/www/html
- Download WordPress:
sudo wget https://wordpress.org/latest.tar.gz
- Extract the downloaded file:
sudo tar -xvzf latest.tar.gz
- Rename the WordPress directory:
sudo mv wordpress your_domain
Editing the Configuration File
- Create a WordPress configuration file:
sudo cp /var/www/html/your_domain/wp-config-sample.php /var/www/html/your_domain/wp-config.php
- Open the configuration file for editing:
sudo nano /var/www/html/your_domain/wp-config.php
Replace the database details with the information you used when setting up the MySQL database:
define('DB_NAME', 'wordpress');
define('DB_USER', 'wordpressuser');
define('DB_PASSWORD', 'your_password');
define('DB_HOST', 'localhost');
Save and exit the file.
Uploading WordPress Files to Your EC2 Instance
Now, upload your WordPress files to your EC2 instance using SFTP or SCP. You can use tools like FileZilla or the scp
command to transfer files to /var/www/html/your_domain
.
7. Domain Configuration
To access your WordPress site using your domain name, you need to configure DNS records:
Configuring DNS Records
- Log in to your domain registrar’s website.
- Navigate to the DNS management section.
- Add an “A” record pointing to your Elastic IP address.
- Add a “CNAME” record for the “www” subdomain (if desired).
8. Securing Your WordPress Installation
Security is crucial for any website. Here are some essential security measures:
SSL Certificate Setup
You can use AWS Certificate Manager to obtain a free SSL/TLS certificate for your domain. Once obtained, associate it with your Elastic Load Balancer (if you choose to use one) or your EC2 instance.
Basic Security Measures
- Regularly update WordPress, themes, and plugins.
- Use strong passwords and consider using a password manager.
- Limit login attempts and install security plugins.
- Disable directory listing and enable a firewall (e.g., AWS WAF).
