How do I configure Nginx as a reverse proxy?

To configure Nginx as a reverse proxy, you need to set up a server block in your Nginx configuration file. Do you have a specific backend server in mind?

Yes, I want to proxy requests to a Node.js application running on port 3000.

Great! You can use the following configuration:

server {
    listen 80;
    server_name your_domain.com;

    location / {
        proxy_pass http://localhost:3000;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;
    }
}

Make sure to replace your_domain.com with your actual domain.

Do I need to restart Nginx after making these changes?

Yes, after updating the configuration file, you should restart Nginx to apply the changes. You can do this with the command sudo systemctl restart nginx.

What if I want to add SSL to my reverse proxy?

To add SSL, you'll need to obtain an SSL certificate and modify your server block to listen on port 443. Would you like guidance on obtaining a certificate?
