NGINX („engine X“) installieren

Den Webserver NGINX auf dem Raspberry Pi installieren:

NGINX ist eine schlanke Webserver-Alternative und bietet die Möglichkeit einen Websocket-Proxy einzurichten. Davon soll in Kombination mit NODEJS Gebrauch gemacht werden. Eine Installationsanleitung für NODEJS findet sich hier: INSTALL NODEJS

Um NGINX als WebSocket Proxy verwenden zu können muss eine Version >= 1.3 verwendet werden. Ältere Wheezy Raspbian Versionen installieren noch eine Version 1.2 – damit funktioniert der WebSocket Proxy nicht.

1. Herausfinden welche Version über apt-get installiert weden würde:

pi@raspberrypi:/ $ sudo apt-cache show nginx
Package: nginx
Version: 1.6.2-5+deb8u1
Installed-Size: 99
Maintainer: Kartik Mistry <kartik@debian.org>
Architecture: all
Depends: nginx-full (>= 1.6.2-5+deb8u1) | nginx-light (>= 1.6.2-5+deb8u1) | nginx-extras (>= 1.6.2-5+deb8u1), nginx-full (<< 1.6.2-5+deb8u1.1~) | nginx-light (<< 1.6.2-5+deb8u1.1~) | nginx-extras (<< 1.6.2-5+deb8u1.1~)

Description: small, powerful, scalable web/proxy server
 Nginx ("engine X") is a high-performance web and reverse proxy server
 created by Igor Sysoev. It can be used both as a standalone web server
 and as a proxy to reduce the load on back-end HTTP or mail servers.
 .
 This is a dependency package to install either nginx-full (by default) or
 nginx-light.

2. NGINX installieren – hier ist es die Version 1.62, ggf. lohnt sich ein Wechsel von Raspbian Wheezy auf Jessie.

sudo apt-get install nginx
sudo apt-get install php5-fpm php5-cgi php5-cli php5-common

3. NGINX konfigurieren

sudo nano /etc/nginx/sites-enabled/default

Hier eine exemplarische Beispiel-Konfiguration die lediglich der Veranschaulichung dienen soll:

##
# You should look at the following URL's in order to grasp a solid understanding
# of Nginx configuration files in order to fully unleash the power of Nginx.
# http://wiki.nginx.org/Pitfalls
# http://wiki.nginx.org/QuickStart
# http://wiki.nginx.org/Configuration
#
# Generally, you will want to move this file somewhere, and start with a clean
# file but keep this around for reference. Or just disable in sites-enabled.

# Please see /usr/share/doc/nginx-doc/examples/ for more detailed examples.

Webserver neu starten:

sudo service nginx restart

ggf.

sudo service php5-fpm restart
