Running WordPress on AWS (Amazon Web Services) involves configuring and deploying the necessary resources to create a scalable and reliable WordPress website. Here's a step-by-step guide on how to do it:
- Select an appropriate EC2 (Elastic Compute Cloud) instance: EC2 instances are virtual servers where your WordPress website will run. Choose an instance type based on your website's size and expected traffic. Make sure to consider factors like CPU, RAM, storage, and network performance.
- Set up a VPC (Virtual Private Cloud): A VPC is a logically isolated network within the AWS cloud. It provides security by allowing you to control traffic flow and access to AWS resources. Create a VPC and configure subnets, route tables, and security groups as per your requirements.
- Launch an EC2 instance: Launch an EC2 instance within your VPC and choose a suitable Amazon Machine Image (AMI) that comes pre-installed with WordPress. Set up the instance with appropriate storage, security groups, and key pair access.
- Configure an Elastic IP address: By default, the public IP address of your EC2 instance may change each time it restarts. Associate an Elastic IP address with your instance to provide a static and permanent address for your website.
- Set up an RDS (Relational Database Service) instance: RDS provides a managed database service, ensuring high availability and easy scaling. Choose a suitable database engine like MySQL, create an RDS instance, and configure it. Remember to securely store the database credentials.
- Connect EC2 and RDS: Establish a connection between your EC2 instance and the RDS database by adding the database details in the wp-config.php file of your WordPress installation. This will allow WordPress to save and retrieve data from the RDS database.
- Configure DNS using Route 53: Route 53 is Amazon's DNS management service. Create a hosted zone for your domain, set up your domain name, and configure DNS settings to route website traffic to your EC2 instance.
- Set up a load balancer (optional): If your website is expected to receive high traffic or you want to enhance its availability, set up an Elastic Load Balancer (ELB) to distribute incoming traffic across multiple EC2 instances. This helps in scaling and maintaining high performance.
- Enable SSL/TLS certificate: To secure your website with HTTPS, provision an SSL/TLS certificate using AWS Certificate Manager. Associate the certificate with the load balancer or EC2 instance to ensure encrypted traffic.
- Configure backups and monitoring: Enable regular backups of your EC2 instance, RDS database, and any other critical resources. Set up monitoring using AWS CloudWatch to get alerts on performance, resource usage, and other important metrics.
Once you have completed these steps, you should have a fully functional WordPress website running on AWS. You can further enhance and optimize your setup based on your specific requirements and preferences.
