nginx - Enable HTTP/2
Nov 23, 2016
Make sure your version of nginx has been built with HTTP/2 support. The dotdeb releases have it enabled and can be easily installed.
nginx -V should contain --with-http_v2_module.
Enabling HTTP/2 support is as simple as adding it to the listen option of your config:
listen 443 ssl http2;
listen [::]:443 ssl http2;
Reload nginx:
systemctl reload nginx.service
