ToggleStep-by-Step Guide to Setting Up WordPress Site on AWS
Setting up WordPress on AWS is a straightforward process that involves creating an instance, connecting via SSH, and configuring your site for optimal performance. Follow these steps to get your WordPress site up and running on AWS quickly and efficiently.
Step 1: Create an Amazon Lightsail Account
To start, you’ll need an AWS account. If you don’t have one:
- Go to the Amazon Lightsail website.
- Click on “Create Account” or “Sign In” if you already have an account.
- Follow the instructions to complete the sign-up process.
Note: Amazon Lightsail is Free Tier eligible for 12 months, giving you the opportunity to explore the services without cost.
Once signed up, you can begin setting up your WordPress instance.

Step 2: Create a WordPress Instance in Lightsail
Now, let’s set up a WordPress instance on Amazon Lightsail.
- Sign in to the Lightsail Console and access the Lightsail dashboard.
- Click on “Create instance” under the Instances tab.
- Select your Region and Availability Zone (this is preselected, but you can change it if needed).

Next, select your plan:
- Lightsail offers different plans with varying resources. You can start with the $3.50 USD plan, which is Free Tier eligible.
Finally, name your instance:
- Give it a unique name (e.g., “myblog-instance”). The name should be 2-255 characters long, starting and ending with an alphanumeric character.
Click Create instance, and AWS will begin launching your WordPress instance. This may take a few minutes.
Step 3: Connect to Your Instance via SSH and Retrieve the WordPress Password
Once your WordPress instance is running, you’ll need to connect via SSH to retrieve the WordPress admin password.
- In the Lightsail Console, go to the Instances tab.
- Click on the SSH quick-connect icon next to your WordPress instance to open the browser-based SSH client.
To get the WordPress admin password:
- In the SSH terminal, enter the command:
cat $HOME/bitnami_application_password - The password will be displayed on the screen. Save it for future use.
Step 4: Sign in to the WordPress Admin Dashboard
Now that you have the password, log in to the WordPress admin panel and start customizing your site.
- Open a web browser and navigate to:
http://<PublicIpAddress>/wp-login.php - Replace <PublicIpAddress> with the public IP of your instance, found in the Lightsail console.
Use the following credentials:
- Username: user
- Password: The password retrieved via SSH.
Once logged in, you can start customizing your site by changing themes, installing plugins, and more.
Step 5: Create a Static IP Address and Attach It to Your Instance
By default, AWS assigns a dynamic public IP to your instance, which changes if the instance is restarted. To avoid this, assign a static IP to ensure your site remains accessible.
- In the Lightsail Console, select your WordPress instance.
- Go to the Networking tab and click Create static IP.
- Attach the static IP to your WordPress instance by selecting it from the dropdown menu.
- Name your static IP and click Create.
Your WordPress instance is now associated with a static IP, ensuring consistency.
Step 6: Create DNS Zone & Map a Domain to Your WordPress Instance
To make your WordPress site accessible via a domain name, create a DNS zone and map your domain to the static IP address.
- In the Lightsail Console, go to the Networking tab.
- Click Create DNS zone and enter your domain name.
Add the name servers to your domain registrar:
- Lightsail will provide name server addresses. Log into your domain registrar and update your domain’s name servers to point to the Lightsail name servers.
To map your domain:
- In the DNS zone settings in Lightsail, add an A record.
- Use @ for the subdomain to map the apex of your domain.
- Select the static IP address of your WordPress instance and save the record.
Allow some time for the DNS changes to propagate (this can take a few minutes to several hours). Once complete, your domain will direct users to your WordPress site hosted on AWS.
Step 7: Clean Up Unused Instances
To avoid unnecessary charges, it’s important to delete any unused instances created during testing.
- In the Lightsail Console, click on the ellipsis (⋮) icon next to the instance you want to delete.
- Select Delete and confirm by clicking Yes, delete.
This will remove the instance and any associated charges.
Step 8: Monitoring and Notifications (Optional)
Once your WordPress site is live, setting up monitoring and notifications ensures smooth operations. AWS CloudWatch helps you monitor the performance of your Lightsail instance and set alerts based on resource usage.
- Enable metrics and logs collection for your instance in the Lightsail console.
- Set up alerts based on CPU usage, memory consumption, or disk activity to manage performance proactively.
Step 9: Final Customization and WordPress Optimization
With your WordPress site live, a few final steps will ensure everything runs smoothly:
- Update Permalinks: Go to the WordPress settings and update your permalinks for Search Engine optimization.
- Install Essential Plugins: Add security plugins, caching plugins, and other tools to enhance performance.
- Backup Regularly: Use a plugin or AWS services to backup your WordPress site.
- Optimize for Speed: Leverage CDN services like Amazon CloudFront to ensure faster content delivery.
Advanced Options: Scaling a WordPress Website on Amazon AWS
When handling high-traffic websites, scaling a WordPress site on AWS requires implementing multiple instances and distributing the load efficiently. Here’s how you can deploy a highly scalable WordPress site on AWS:
Use AWS Elastic Load Balancing (ELB) to Distribute Traffic
AWS Elastic Load Balancer (ELB) automatically distributes incoming traffic across multiple EC2 instances. This ensures that no single server is overloaded, improving fault tolerance and making your WordPress site more reliable and scalable.
Steps to Implement ELB:
- In the AWS console, go to EC2 and choose Load Balancers.
- Create a new load balancer and configure it to route traffic to your EC2 instances.
- Ensure that your WordPress instances are registered with the load balancer.
With ELB, your WordPress site will remain operational even if one or more instances fail, ensuring high availability.
Auto Scaling for Dynamic Resource Management
Auto Scaling automatically adjusts the number of EC2 instances based on real-time demand, ensuring that your site has sufficient resources during peak traffic times without unnecessary expenses during off-peak times.
Steps to Set Up Auto Scaling:
- In the AWS EC2 dashboard, go to Auto Scaling Groups.
- Create an Auto Scaling group, setting the minimum and maximum number of instances.
- Configure scaling policies based on CPU utilization or other key metrics.
Auto Scaling will ensure your WordPress site can handle high traffic by adding more instances as needed and scaling down during low-traffic periods.
Offload the Database with Amazon RDS
When dealing with high-traffic WordPress websites, managing your database separately ensures better performance. Amazon RDS (Relational Database Service) allows you to offload your database from your application server, ensuring that the database can scale independently.
How to Implement RDS:
- Go to the AWS RDS console and create a new database instance.
- Choose the appropriate instance type for your WordPress database.
- Migrate your WordPress database to RDS, enabling automatic backups and failover.
RDS provides high availability, automated backups, and the ability to handle large amounts of data, making it ideal for scalable WordPress websites.

Use Amazon CloudFront for Content Delivery
To reduce the load on your server and improve page load times, use Amazon CloudFront, AWS’s Content Delivery Network (CDN). CloudFront caches static content like images, CSS, and JavaScript at edge locations around the world, speeding up content delivery to your users.

How to Set Up CloudFront:
- In the AWS console, go to CloudFront and create a new distribution.
- Configure CloudFront to cache and distribute your WordPress site’s static assets.
- Integrate CloudFront with your EC2 instances or S3 buckets to deliver content faster.
By using CloudFront, you reduce the load on your EC2 instances and ensure faster content delivery for users worldwide.
Enable Caching with ElastiCache
To further optimize your WordPress site for high traffic, implement AWS ElastiCache, which provides in-memory caching using Redis or Memcached. This helps reduce database load and speeds up data retrieval.
How to Implement ElastiCache:
- Go to the AWS ElastiCache console and create a new cache cluster.
- Choose Redis or Memcached as the caching engine.
- Integrate ElastiCache with WordPress via caching plugins or custom configurations.
With ElastiCache, your WordPress site can handle a higher volume of requests without overloading the database.
