How to enable h2c in Nginx?

问题

Is there a way to enable h2c aka HTTP2 cleartext in Nginx 1.9.5 onward?

I've tried using h2 over TLs in https://chronic101.xyz and it works, however I would like to implement h2c on port 80 as well.

Thanks,

chrone

It should be as simple as adding http2 in the end of your listen directive.

Example:

server {
    listen 80 http2;

However, keep in mind that most browsers do not support unencrypted HTTP/2, and so will still serve content as HTTP/1.1.
