NGINX Cookbook

How to do it...

Based on our previous example, we only need to make one key change. Instead of just specifying ssl as the listening protocol, we add http2:

server { 
    listen              443 ssl http2; 
    server_name         http2.nginxcookbook.com; 
    ssl_certificate     /etc/ssl/public.pem; 
    ssl_certificate_key /etc/ssl/private.key; 
    ssl_protocols       TLSv1 TLSv1.1 TLSv1.2; 
    ssl_ciphers         HIGH:!aNULL:!MD5; 
 
    access_log  /var/log/nginx/ssl-access.log  combined; 
 
    location  /favicon.ico { access_log off; log_not_found off; } 
    root  /var/www; 
} 

No changes to protocols or ciphers are necessary. To verify that HTTP/2 is working, you can use Chrome Developer Tools (DevTools) to show the protocol, or an external tool, such as the one KeyCDN provides:
