# 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:

```bash
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:

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

Update package cache:

```bash
sudo apt-get update
```

## Install new nginx

```bash
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`

```bash
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:

```bash
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:

```nginx
  listen 443 http2;
	listen [::]:443 http2;
```

Restart nginx:

```bash
sudo service nginx restart
```

Done.
