Part 7: Domain Cloudflare Namecheap AWS ALB SSL EC2 NodeJS app Nginx Configuration
When setting up a NodeJS application on AWS EC2 instance, it is important to configure the necessary services such as Cloudflare, Namecheap, AWS ALB, SSL, EC2, Nginx, and NodeJS. This article will guide you through the process of setting up your domain, SSL certificate, and load balancer on AWS using Nginx as a reverse proxy.
Step 1: Domain Configuration
First, you need to register a domain name with a registrar like Namecheap. Once you have purchased your domain, you will need to set up the DNS records to point to Cloudflare for managing your DNS settings.
Step 2: Cloudflare Configuration
After setting up your domain in Cloudflare, you need to configure the SSL settings to ensure secure communication between your application and the end-users. Cloudflare offers free SSL certificates that you can use for your domain.
Step 3: AWS ALB Configuration
Next, you need to set up an Application Load Balancer (ALB) on AWS to distribute incoming traffic to your EC2 instances. You can configure the ALB to use HTTPS with your Cloudflare SSL certificate for secure communication.
Step 4: SSL Configuration
After setting up the ALB, you need to install the SSL certificate on your EC2 instances to enable secure communication with your NodeJS application. You can use ACM (Amazon Certificate Manager) to provision an SSL certificate for your domain.
Step 5: EC2 Configuration
Now, you need to set up your EC2 instance with NodeJS installed and running your application. Make sure to configure the security groups and IAM roles to allow traffic from the ALB and other necessary services.
Step 6: Nginx Configuration
Finally, you need to configure Nginx as a reverse proxy to route incoming HTTP and HTTPS traffic to your NodeJS application running on the EC2 instance. You can set up Nginx to listen on port 80 and 443 and proxy the requests to the NodeJS application running on a different port.
Conclusion
By following these steps, you can set up a secure and robust infrastructure for hosting your NodeJS application on AWS using Cloudflare, Namecheap, AWS ALB, SSL, EC2, NodeJS, and Nginx. This configuration will ensure that your application is accessible to users while maintaining high security and performance standards.
