Welcome to our comprehensive guide on NGINX HTTPS server block. In this article, we will dive deep into the steps and best practices to configure your NGINX server block for HTTPS. This guide is designed for website owners, developers, and server administrators, who want to take their website security to the next level. By the end of this guide, you will have a clear understanding of how to implement HTTPS on your NGINX server, and how HTTPS affects your website’s SEO and rankings. So, let’s get started.
Section 1: Introduction to NGINX HTTPS Server Block
Before we proceed, let’s first understand what HTTPS is and why it is important. HTTPS (Hypertext Transfer Protocol Secure) is a protocol for secure communication over the internet. It is essentially a combination of HTTP and SSL/TLS encryption, which encrypts the data transmitted between the client’s browser and the web server. This encryption ensures that no one can intercept or read the data being transmitted, including sensitive information such as passwords and credit card details.
Now that we know the importance of HTTPS, let’s move on to NGINX. NGINX is an open-source, high-performance web server that can be used as a reverse proxy, load balancer, and HTTP/HTTPS server. It is widely used by developers and website owners for its speed, reliability, and security features. In this guide, we will show you how to configure NGINX as an HTTPS server.
Section 2: Basic Configuration of NGINX for HTTPS
Step 1: Install SSL Certificate
The first step to configuring NGINX for HTTPS is to obtain an SSL/TLS certificate. You can either get a free certificate from Let’s Encrypt or purchase one from a commercial Certificate Authority (CA) such as Comodo, Symantec, or GeoTrust. Once you have obtained the certificate, you need to install it on your NGINX server. Here are the steps to install a certificate:
| Step | Description |
|---|---|
| Step 1 | Create a directory to store SSL certificates on your server. |
| Step 2 | Upload the certificate and private key to the directory. |
| Step 3 | Update the NGINX configuration file to point to the certificate files. |
Once you have completed the above steps, your NGINX server will now be able to use HTTPS to communicate with clients.
Step 2: Configure NGINX Server Block for HTTPS
Now that you have installed the SSL/TLS certificate, you can configure NGINX to serve HTTPS requests. Here are the steps to configure NGINX server block for HTTPS:
| Step | Description |
|---|---|
| Step 1 | Open your NGINX configuration file in a text editor. |
| Step 2 | Find the server block for your website. |
| Step 3 | Add the following lines to the server block: |
listen 443 ssl;
ssl_certificate /path/to/certificate.crt;
ssl_certificate_key /path/to/private.key;
The above lines tell NGINX to listen on port 443 for HTTPS requests and to use the SSL certificate and private key files that you installed earlier.
Step 3: Redirect HTTP Requests to HTTPS
Redirecting HTTP requests to HTTPS is essential for website security. Here are the steps to redirect HTTP requests to HTTPS:
| Step | Description |
|---|---|
| Step 1 | Open your NGINX configuration file in a text editor. |
| Step 2 | Add the following lines to the server block: |
server {
listen 80;
server_name example.com www.example.com;
return 301 https://$server_name$request_uri;
}The above lines tell NGINX to listen on port 80 for HTTP requests and redirect them to HTTPS.

Step 4: Enable HSTS
HSTS (HTTP Strict Transport Security) is a security feature that instructs the client’s browser to always use HTTPS for communicating with your website. Here are the steps to enable HSTS:
| Step | Description |
|---|---|
| Step 1 | Add the following line to your HTTPS server block: |
add_header Strict-Transport-Security "max-age=31536000; includeSubDomains" always;The above line tells the client’s browser to always use HTTPS for one year (max-age=31536000) and to include subdomains (includeSubDomains).
Step 5: Enable OCSP Stapling
OCSP Stapling is a security feature that reduces the time it takes to validate SSL certificates. Here are the steps to enable OCSP Stapling:
| Step | Description |
|---|---|
| Step 1 | Add the following line to your HTTPS server block: |
ssl_stapling on;The above line tells NGINX to enable OCSP Stapling.
Step 6: Enable Perfect Forward Secrecy
Perfect Forward Secrecy (PFS) is a security feature that ensures that if a SSL private key is compromised, all past and future communications are still encrypted. Here are the steps to enable PFS:
| Step | Description |
|---|---|
| Step 1 | Generate a Diffie-Hellman parameter file by running the following command: |
openssl dhparam -out /etc/nginx/dhparams.pem 4096The above command generates a 4096-bit Diffie-Hellman parameter file and saves it to /etc/nginx/dhparams.pem.
| Step 2 | Add the following lines to your HTTPS server block: |
ssl_dhparam /etc/nginx/dhparams.pem;
ssl_prefer_server_ciphers on;
ssl_ciphers "EECDH+AESGCM:EDH+AESGCM:AES256+EECDH:AES256+EDH";The above lines tell NGINX to use the Diffie-Hellman parameter file for perfect forward secrecy and to prefer server ciphers that provide forward secrecy.
