How to install nginx (>= 1.9.5) with http2 support on Ubuntu 14.04 LTS (Trusty)

IMPORTANT: Backup your nginx site configs (usually under /etc/nginx/sites-available)!

Remove old nginx

Remove old nginx incl. nginx-common:

apt-get autoremove --purge nginx nginx-common

Add sources list for new nginx

Create /etc/apt/sources.list.d/nginx.list with content:

deb http://nginx.org/packages/mainline/ubuntu/ trusty nginx
deb-src http://nginx.org/packages/mainline/ubuntu/ trusty nginx

Add nginx signing key:

wget -q -O- http://nginx.org/keys/nginx_signing.key | sudo apt-key add -

Update package cache:

sudo apt-get update

Install new nginx

sudo apt-get install nginx

Configs

Fix /etc/nginx/nginx.conf: and add this to the end of the http section:

• Set user to www-data
• Set worker_processes to 4
• Set tcp_nopush to on
• Set tcp_nodelay to on
• Set types_hash_max_size to 2048
• Set server_tokens to off
• Set gzip to on
• Set gzip_disable to "msie6"
• Add include /etc/nginx/sites-enabled/*;

Remove /etc/nginx/conf.d/default.conf

sudo rm -rf /etc/nginx/conf.d/default.conf

Fix /etc/nginx/fastcgi_params:

• Add fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

Add sites-* folders:

sudo mkdir /etc/nginx/sites-available /etc/nginx/sites-enabled

Add your previously backuped site configs and enable them by symlinking in /etc/nginx/sites-enabled.

Enable http2

Add to your https hosts congig:

  listen 443 http2;
	listen [::]:443 http2;

Restart nginx:
