Architecture

• VPC with public and private subnets across two availability zones
• EC2 instance running WordPress in a public subnet
• RDS MySQL instance in private subnets
• NAT Gateway for outbound internet access from private subnets
• Security groups for EC2 and RDS instances

Prerequisites

• AWS CLI configured with appropriate credentials
• Terraform (v0.12+)
• Ansible (v2.9+)
• SSH key pair for EC2 instance access

Setup

1. Clone this repository:

   git clone <repository-url>
   cd <repository-name>
   

2. Initialize Terraform:

   terraform init
   

3. Create a terraform.tfvars file with the following content:

   db_username = "your_db_username"
   db_password = "your_db_password"
   

4. Deploy the infrastructure:

   terraform apply
   

5. Set up environment variables for Ansible:

   source scripts/set_env.sh
   

6. Run the Ansible playbook:

   ansible-playbook -i ansible/inventory/inventory.ini \ 
     -u ec2-user \
     --private-key=~/.ssh/aws-key-pair.pem \
     -e "ansible_ssh_common_args='-o StrictHostKeyChecking=no'" \
     ansible/playbooks/wordpress_setup.yml
   

Accessing WordPress

After successful deployment, you can access your WordPress site using the EC2 instance's public IP or public DNS, which can be found in the Terraform outputs.
