 <\/p>\n

Experimental support for HTTP\/2 became available in Nginx version 1.9.5 (mainline). It is really easy to enable, and I\u2019ll show you how.<\/span><\/p>\n

First of all: If you\u2019re not running the latest version yet, I recommend that you upgrade Nginx to the latest version<\/a>.<\/p>\n

\n

If you\u2019re already running SPDY, please note that the SPDY module have been replaced with the HTTP\/2 module in Nginx. Fortunately, to run HTTP\/2 you just need to upgrade to Nginx 1.9.5 or later and replace spdy<\/code> with http2<\/code> on your listen<\/code> directive line.<\/p>\n

\n

Now, make sure your version of Nginx is compiled with HTTP\/2 support:<\/p>\n

$ nginx -V\r\n<\/code><\/pre>\n
Make sure you can find --with-http_v2_module<\/code> somewhere in that output. If you don\u2019t, upgrade to a build that supports HTTP\/2 \u2013 like the link I posted above.<\/p>\n
<\/div>\n
Now it is as simple as adding a single word to your Nginx config. Open the server block config for your HTTPS site (all implementations of HTTP\/2 require HTTPS), and change this line:<\/p>\n
listen 443 ssl;\r\n<\/code><\/pre>\n
to:<\/p>\n
listen 443 ssl http2;\r\n<\/code><\/pre>\n
and reload your config:<\/p>\n
$ service nginx reload\r\n<\/code><\/pre>\n
(If you haven\u2019t enabled HTTPS yet, check this post: Securing Nginx with HTTPS<\/a>)<\/p>\n
Now all HTTP\/2 enabled visitors should get your site delivered over HTTP\/2, while older browsers get regular SSL (really: TLS). Major browsers supports HTTP\/2 now<\/a>.<\/p>\n
The only thing left, is that you probably want to route all visitors that comes through standard HTTP on port 80 to your HTTPS port 443<\/a>.<\/p>\n
If you haven\u2019t already done so, you are now ready to optimize HTTPS on Nginx<\/a>.<\/p>\n
