How to configure Nginx using SSL certificates

Configuring Nginx with SSL certificates protects your website from snooping and cyber attacks and builds user trust.

Step 1: Obtain the SSL certificate

• Obtain an SSL certificate from a trusted certificate authority (CA).
• Follow the steps of the CA to generate a certificate signature request (CSR).
• Submit a CSR to obtain an SSL certificate.

Step 2: Configure the Nginx virtual host

• Create a new virtual host block in your Nginx configuration file.
• Include the following instructions in the virtual host block:

 <code>listen 443 ssl; server_name www.example.com; ssl_certificate /path/to/ssl.crt; ssl_certificate_key /path/to/ssl.key;</code>

• Replace www.example.com with your domain name.
• Replace /path/to/ssl.crt with the path to the SSL certificate file.
• Replace /path/to/ssl.key with the path to the SSL key file.

Step 3: Redirect to HTTPS

• Add the following directive in the virtual host block to redirect all HTTP requests to HTTPS:

 <code>rewrite ^ https://$server_name$request_uri? permanent;</code>

Step 4: Test the configuration

• Restart Nginx.
• Verify your SSL configuration using an SSL testing tool such as ssllabs.com.

Other notes:

• Make sure your SSL certificate is the latest version.
• Renew your SSL certificate regularly.
• Enable the SSL enforce option in your Nginx configuration to ensure that all traffic is over HTTPS.
• Consider using the HTTP/2 protocol to improve website performance.
