How to deal with Nginx in production!

In the ever-evolving digital landscape, blazing-fast website performance isn’t a luxury – it’s a necessity. Delight your visitors and outpace competitors by implementing advanced strategies like Nginx, SSL, secure connections, caching, and production optimization.
Let’s embark on a journey to unlock unparalleled speed and security for your online presence.

The power of SSL Security with Nginx

The Power of SSL Security with Nginx: Strengthening Your Website’s Foundation

Embrace the prowess of Nginx, the high-performance web server and reverse proxy, to fortify your website’s foundation.
Nginx’s lightweight architecture and efficient event-driven model ensure lightning-fast content delivery.
By seamlessly integrating SSL (Secure Sockets Layer), you encrypt data transmission to boost trust between your business and the client.
Combine these technologies for an impregnable fortress of security that inspires confidence in your users.

Install SSL certificates with Certbot

Installing SSL certificates for free with Certbot is a straightforward process that can greatly enhance the security of your website. Follow these steps to install SSL using Certbot:

1. Next, install Certbot using the certbot-nginx package:

   sudo apt update && apt install certbot-nginx 

2. After the installation is complete, Certbot will automatically configure Nginx to work with SSL.
3. Now, you are ready to request an SSL certificate for your domain.
   Run the following command, replacing example.com with your own domain name:

   sudo certbot --nginx -d example.com 

4. Restart Nginx to apply the new SSL configuration:

   sudo service nginx restart
   

5. You’re done! Your website is now secured with SSL. You can access your website using https://example.com, and visitors will see the padlock icon indicating a secure connection.

Remember that SSL certificates expire after a certain period. Luckily, Certbot is equipped with automatic renewal functionality, ensuring that your SSL certificates are always up to date.

Installing SSL with Certbot and enabling secure connections is a vital step in safeguarding your website and building trust with your users. Enjoy the peace of mind that comes with having a secure online presence!

server {
    listen 443 ssl;
    server_name example.com;
    ssl_certificate /path/to/ssl_cert.crt;
    ssl_certificate_key /path/to/ssl_private_key.key;
    # Other SSL and server configurations
}

Your server needs a Caching strategy

Secure connections via HTTPS are non-negotiable today. Leverage modern security protocols like TLS 1.3 for enhanced encryption and faster connections. Take caching up a notch by implementing browser and server-side caching, reducing load times for returning users.
Nginx’s proxy_cache directive empowers you to cache responses efficiently, minimizing redundant server requests.

http {
  proxy_cache_path /path/to/cache levels=1:2 keys_zone=my_cache:10m max_size=10g inactive=60m use_temp_path=off;

  server {
    listen 80;
    server_name example.com;

    location / {
      proxy_pass http://backend-server;
      proxy_cache my_cache;
      proxy_cache_valid 200 302 5m;
      proxy_cache_valid 404 1m;
      proxy_cache_revalidate on;
      proxy_cache_use_stale error timeout updating http_500 http_502 http_503 http_504;
      proxy_cache_background_update on;
      proxy_cache_lock on;
    }
  }
}

In this configuration:

• The proxy_cache_path directive sets the storage location and other properties for the cache. You can adjust the path, levels, keys_zone, max_size, and inactive parameters according to your needs.
• Inside the server block, the location / block defines the location or URL to be cached. In this example, it’s set to /, which represents the root.
• The proxy_pass directive specifies the backend server where Nginx will proxy requests.
• The proxy_cache directive enables caching and associates it with the my_cache zone defined in the proxy_cache_path directive.
• The proxy_cache_valid directive sets the maximum time to keep the cached response valid for specific HTTP status codes.
• The proxy_cache_revalidate, proxy_cache_use_stale, proxy_cache_background_update, and proxy_cache_lock directives control various cache-related behaviors and optimizations.

Your data must be compressed and optimized

Optimizing for production is an art that involves meticulous attention to detail. Employ uncommon yet impactful practices like implementing Content Security Policy (CSP) headers to thwart cross-site scripting attacks. Utilize HTTP/2 for parallel loading of assets, giving your site a quantum leap in speed. Minify your CSS and JavaScript to trim excess bytes, ensuring a lean and lightning-quick user experience.

To compress and optimize data transfer in Nginx, you can use the gzip module and set appropriate configurations in your Nginx configuration file. Here’s an example of an Nginx configuration that enables data compression and optimization:

http {
    # Other server configurations...

    gzip on;
    gzip_disable "msie6";
    gzip_vary on;
    gzip_proxied any;
    gzip_comp_level 5;
    gzip_buffers 16 8k;
    gzip_http_version 1.1;
    gzip_types text/plain text/css application/json application/javascript text/xml application/xml application/xml+rss text/javascript;

    # Other server configurations...
}

In this configuration:

• The gzip on; directive enables gzip compression.
• The gzip_disable "msie6"; directive disables gzip compression for Internet Explorer 6, which is no longer widely used.
• The gzip_vary on; directive adds the Vary: Accept-Encoding header to responses, indicating that the response can vary based on the client’s acceptance of compressed content.
• The gzip_proxied any; directive allows Nginx to compress responses for all types of proxied requests.
• The gzip_comp_level 5; directive sets the compression level to 5.
• The gzip_buffers 16 8k; directive sets the size and number of buffers for gzip compression.
• The gzip_http_version 1.1; directive enables gzip compression for HTTP/1.1 and newer versions.
• The gzip_types directive specifies which MIME types should be compressed. You can modify this list to suit your requirements.

By using this configuration, Nginx will compress eligible responses, reducing their size and optimizing data transfer for improved performance. Your website visitors will benefit from faster loading times and a more efficient browsing experience.

The SEO Advantage

Beyond delivering an exceptional user experience, speed is a crucial SEO factor. Search engines favor swift-loading websites, propelling them up the search results ladder. Nginx’s efficient handling of requests, combined with SSL encryption and intelligent caching, earns your site coveted SEO points. Invest in your website’s future by prioritizing performance, security, and seamless user interactions.

Google PageSpeed Insights provides a detailed report that evaluates various aspects of a website’s performance, including page loading speed and optimization opportunities. The tool assigns a score to each page, ranging from 0 to 100, indicating the level of optimization.
