The Ultimate Guide to Installing WordPress on AWS in 2023

Are you looking to host your WordPress site on a powerful, scalable, and reliable platform? Amazon Web Services (AWS) might be just what you need.

In this guide, we‘ll walk through the process of installing WordPress on AWS step-by-step. Whether you‘re a seasoned developer or just getting started with WordPress, you‘ll learn how to leverage AWS‘s cloud computing services to take your site to the next level.

Why Host WordPress on AWS?

WordPress is the most popular content management system in the world, powering over 40% of all websites. Many of the world‘s largest brands and high-traffic sites run WordPress, including TechCrunch, The New Yorker, and even Beyoncé.

While WordPress itself is free and open-source, it requires a web server to run on. That‘s where hosting comes in. AWS is an ideal platform for hosting WordPress sites because it offers:

• Scalability – AWS makes it easy to scale your server resources up or down based on traffic demands. You can start small and grow as needed without ever changing hosts.

• Performance – With AWS‘s global network of data centers and edge locations, you can deliver content quickly to users around the world. Tools like CloudFront CDN can further boost speed.

• Reliability – AWS is known for its high uptime and built-in redundancy. You can spread your site across multiple availability zones for even greater fault tolerance.

• Flexibility – With AWS, you have complete control over your server environment. You can choose your operating system, web server, PHP version, and more.

• Security – AWS provides a secure foundation with built-in firewalls, DDoS protection, and encryption. You can further enhance security through IAM permissions, SSL certificates, and security groups.

Of course, with great power comes a bit more complexity. AWS has a steeper learning curve than a simple web host. But if you‘re serious about your WordPress site, it‘s well worth the effort to learn. Let‘s get started!

Manual WordPress Install on an EC2 Instance

The most flexible way to run WordPress on AWS is to manually install it on an EC2 (Elastic Compute Cloud) instance. Here‘s how:

1. Launch an EC2 instance

   • Log in to the AWS Management Console and navigate to the EC2 dashboard.
   • Click "Launch instance" and select an Amazon Machine Image (AMI) with the Linux distribution of your choice (I recommend Amazon Linux 2).
   • Choose an instance type based on your needs. For testing, a t2.micro instance (free tier eligible) is a good start.
   • Configure your instance details, including the VPC, subnet, and security groups. Make sure to allow traffic on ports 80 (HTTP), 443 (HTTPS), and 22 (SSH).
   • Review and launch your instance. Create a new key pair or select an existing one to securely connect.

2. Connect to your instance with SSH

   Once your instance is running, select it in the EC2 dashboard and click "Connect". Follow the instructions to SSH into your server. It will look something like:

   ssh -i "your-key-pair.pem" ec2-user@your-instance-public-dns

3. Install the LAMP stack

   Now you‘ll install the Linux, Apache, MySQL, and PHP (LAMP) software needed to run WordPress:

   sudo yum update -y
   sudo amazon-linux-extras install -y lamp-mariadb10.2-php7.2 php7.2
   sudo yum install -y httpd
   sudo systemctl start httpd
   sudo systemctl enable httpd

4. Install and configure the database

   sudo yum install -y mariadb-server
   sudo systemctl start mariadb
   sudo mysql_secure_installation

   When prompted, set a root database password and follow the prompts to secure your installation.

   Now create a WordPress database and user:

   sudo mysql -u root -p
   CREATE DATABASE wordpress;
   CREATE USER ‘wordpress‘@‘localhost‘ IDENTIFIED BY ‘your-password‘;
   GRANT ALL ON wordpress.* TO ‘wordpress‘@‘localhost‘;
   FLUSH PRIVILEGES;
   EXIT;

5. Download and configure WordPress

   wget https://wordpress.org/latest.tar.gz
   tar -xzf latest.tar.gz
   cp wordpress/wp-config-sample.php wordpress/wp-config.php
   nano wordpress/wp-config.php

   Update the database connection details in wp-config.php with the values from step 4.

   define( ‘DB_NAME‘, ‘wordpress‘ );
   define( ‘DB_USER‘, ‘wordpress‘ );
   define( ‘DB_PASSWORD‘, ‘your-password‘ );

   Save and exit the file.

6. Move WordPress files and configure permissions

   sudo cp -r wordpress/* /var/www/html/
   sudo chown -R apache /var/www/html
   sudo chgrp -R apache /var/www/html
   sudo chmod 2775 /var/www/html
   find /var/www/html -type d -exec sudo chmod 2775 {} \;
   find /var/www/html -type f -exec sudo chmod 0644 {} \;

7. Access the WordPress installer

   Open a web browser and navigate to your EC2 instance‘s public DNS (found on the EC2 dashboard). You should see the WordPress setup wizard. Follow the prompts to set your site title, admin user, and install WordPress.

Congrats, you now have a working WordPress site on AWS! But you‘re not done yet. Let‘s cover some important next steps.

Post-Install WordPress Configuration on AWS

To get the most out of hosting WordPress on AWS, you‘ll want to configure a few key things:

1. Assign a domain name

   By default, your WordPress site is only accessible via the EC2 instance‘s public IP or DNS. To use a custom domain name, you‘ll need to register one and point it to your server.

   I recommend using AWS‘s Route 53 service to manage your domain within AWS. You can also use a third-party registrar like Namecheap or Google Domains.

   In your domain‘s DNS settings, create an A record pointing to your EC2 instance‘s public IP. You may also want to set up a www subdomain as an alias (CNAME record) to your root domain.

2. Install an SSL certificate

   To enable HTTPS on your WordPress site (which you should always do), you‘ll need an SSL certificate. AWS offers free certificates through the AWS Certificate Manager (ACM) service.

   Request a new public certificate in ACM for your domain name. Then load the certificate onto your EC2 instance using the AWS CLI.

   Finally, configure your Apache web server to use the certificate. Update your virtual host file (e.g. /etc/httpd/conf.d/ssl.conf) with the certificate paths:

   SSLCertificateFile /path/to/your/certificate.crt
   SSLCertificateKeyFile /path/to/your/certificate.key
   SSLCertificateChainFile /path/to/your/certificate-chain.crt

3. Implement a backup strategy

   Don‘t let server issues take your site offline. Plan automated backups to secure your data.

   Some popular options for backing up WordPress on AWS are:

   • Duplicator plugin – create full site backups and store them on S3
   • UpdraftPlus plugin – back up files and database to various cloud storage providers
   • AWS Backup – automate EBS snapshots and store them in S3
   • VaultPress (Jetpack) – premium WordPress backup service

   Choose a backup tool that fits your needs and budget. Configure it to run automated backups on a regular schedule (at least daily). And don‘t forget to periodically test restoring your backups!

4. Enhance speed & security

   A few other optimizations to consider for your WordPress site on AWS:

   • Implement caching – Services like CloudFront (CDN) or plugins like WP Rocket can dramatically improve site performance by caching content at the edge

   • Harden WordPress security – Keep core, themes, and plugins updated, use strong passwords, limit login attempts, and hide the wp-admin directory

   • Monitor server metrics – Use AWS CloudWatch to keep an eye on CPU, memory, and disk usage and set up alerts to proactively address issues

   • Automate software updates – Enable automatic updates for the OS and web server to get the latest security patches (note: be careful with automatic WordPress core updates in case of incompatibilities)

Estimating AWS Hosting Costs

AWS pricing is complex and variable since it‘s based on your actual usage across many services. That said, we can get a rough estimate of WordPress hosting costs on AWS.

Assuming a single t3.small instance in the us-east-1 region, here‘s a sample monthly cost breakdown:

Keep in mind this is just an estimate. Your actual costs will depend on your specific usage and needs. Some money-saving tips:

• Use reserved instances for long-term, predictable workloads
• Right-size your instances and database based on actual usage
• Implement caching to reduce data transfer out
• Clean up unused resources like old EBS volumes

Luckily, AWS has a pricing calculator to help you estimate costs across services. Play around with instance types, storage, and data transfer to see how your costs might grow over time.

Using Lightsail to Simplify WordPress Hosting

If the manual EC2 install process seems intimidating, don‘t worry. AWS offers a simplified hosting option called Lightsail that‘s perfect for WordPress.

Lightsail is a virtual private server (VPS) service that offers preconfigured, one-click deployments for popular apps like WordPress. Under the hood, it‘s built on the same infrastructure as EC2. But Lightsail is designed to be much easier to use, especially for users new to AWS.

Here‘s how to launch a WordPress instance with Lightsail:

1. In the AWS Console, navigate to the Lightsail service and click Create instance.
2. Choose the Linux/Unix platform and the WordPress blueprint.
3. Select your instance plan and sizing. The cheapest $3.50/mo plan is a good place to start.
4. Name your instance and click Create to launch it.
5. Once the instance is running, note the public IP address and WordPress login details.

And that‘s it! Your WordPress site is ready to go, no manual configuration required. Lightsail instances also include:

• A static IP address
• A free SSL certificate (via Let‘s Encrypt)
• Automatic WordPress core updates
• Daily backups and one-click restore
• A management console for easy monitoring and metrics

The main trade-off with Lightsail is less flexibility compared to a manual EC2 setup. But for many WordPress users, the simplicity is worth it. You can always graduate to a full EC2 setup later if needed.

Conclusion

We covered a lot in this guide, but you should now have a solid foundation to install and run WordPress on AWS. Whether you choose the power and flexibility of a manual EC2 setup or the simplicity of Lightsail, you‘ll be able to tap into the performance, scalability, and reliability of AWS‘s cloud platform.
