Nginx with HTTP2
Check your nginx version and you need 1.9.5+, for upgrading on Ubuntu do someting like this
sudo apt-get purge nginx nginx-common
Add nginx source to source.list
deb http://nginx.org/packages/mainline/ubuntu/ trusty nginx deb-src http://nginx.org/packages/mainline/ubuntu/ trusty nginx
and install new version
sudo apt-get update sudo apt-get install nginx
For sure check version
root@cfg01:/ # dpkg -l | grep nginx ii nginx 1.9.9-1~trusty amd64 high performance web server
Now if you already have configured site with ssl you can just add http2
server {
listen 443 ssl http2;
...
Also you must ensure for redirecting all traffic from http to https and disable spdy if is configured.
Finally to verify that HTTP/2 translation is working, you can use the “HTTP/2 and SPDY indicator” plug-in available for Google Chrome and Firefox or for online sites is tool here.
I have this problem with gzip compression.
