Benefits of Nginx and Passenger for Ruby on Rails

1. Efficient Handling of Requests: Nginx, combined with Passenger, efficiently manages incoming requests, balancing the load and handling multiple requests concurrently.
2. Enhanced Performance: This setup is known for its ability to improve the performance of Ruby on Rails applications significantly.
3. Scalability and Reliability: Nginx and Passenger provide a scalable solution that ensures the reliability of your application under various loads.

Configuration Steps

Setting Up the Environment

1. Install Ruby and Rails: Ensure that Ruby on Rails is installed on your Linux server.

Installing Nginx and Passenger

1. Install Phusion Passenger: Passenger is an application server specifically designed for Ruby, Node.js, and Python applications.

   sudo apt-get install -y dirmngr gnupg
   sudo apt-get install -y nginx-extras passenger

2. Configure Passenger with Nginx: Edit the Nginx configuration file to include Passenger settings:

   # In /etc/nginx/nginx.conf
   include /etc/nginx/passenger.conf;

Deploying the Rails Application

1. Prepare Your Rails Application: Set up your Rails application, ensuring it’s ready for deployment (e.g., production database configuration, precompiling assets).
2. Nginx Server Block Configuration: Configure a server block in Nginx for your Rails application.

   server {
       listen 80;
       server_name example.com;
       root /path/to/your/rails/app/public;

       passenger_enabled on;
       passenger_app_env production;

       location / {
           # Passenger configurations...
       }
   }

SSL Configuration

1. Implement SSL: Secure your application by setting up an SSL certificate with Let’s Encrypt or another provider.

   server {
       listen 443 ssl http2;
       server_name example.com;

       ssl_certificate /path/to/ssl/certificate.pem;
       ssl_certificate_key /path/to/ssl/private/key.pem;

       root /path/to/your/rails/app/public;
       passenger_enabled on;
       passenger_app_env production;

       # Other configurations...
   }

2. Redirect HTTP to HTTPS (optional): Configure Nginx to redirect all HTTP requests to HTTPS for security.

Performance Tuning

• Optimize Passenger Settings: Adjust Passenger’s configurations, such as passenger_max_pool_size and passenger_min_instances, to optimize resource usage based on your server’s capacity.

Running and Testing

• Start Nginx and Passenger: Ensure Nginx is running with the Passenger module enabled.
• Test the Deployment: Verify that the Rails application is accessible and functioning correctly through the web.
