Nginx with full HTTP/2 support on Centos 7

Modern web goodies

Getting sweet HTTP/2 support with TLS encryption and ALPN on nginx involves compiling nginx version above 1.9.5 with OpenSSL version above 1.0.2.

OpenSSL with required version will be available in Centos from version 7.4, but we want it now.

Requirements

  • Centos 7 minimal install
  • suggested: domain with TLS certificate attached in nginx config

nginx install script (thanks to https://github.com/moneytoo)

Script assume current user has root rights.

All that is left is adding http2 to listen segment in nginx config:

listen 443 http2;

Restart the server with

systemctl restart nginx.service

and you can enjoy nginx with HTTP/2 and ALPN on Centos7.
