How to get already installed NGINX to use OpenSSL 1.0.2 for ALPN?


I would like to use HTTP/2 and to fully use its capabilities, it needs ALPN (and not NPN). ALPN is bundled in OpenSSL 1.0.2, but NGINX doesn’t seem to use it. I have upgraded everything and currently I am at NGINX 1.10.0 and OpenSSL 1.0.2h.

As you can see in the screenshot above, OpenSSL 1.0.2h is indeed installed on the server as is the latest version of NGINX 1.10.0. OpenSSL was already at 1.0.2h when I upgraded from NGINX 1.9 to 1.10.

Any help to get NGINX to use OpenSSL 1.0.2 or how I can enable ALPN would be greatly appreciated.

Thank you!

PS I have no clue on how I could recompile NGINX. I’ve always simply used apt-get install nginx.

My way to have http2 + alpn on Add jessie-backports repository

deb jessie-backports main

Install openssl with apt-get

apt-get -t jessie-backports install openssl

and then rebuild nginx from source “as is”.

Yeah! supports HTTP/2.0.
ALPN supported.
