Internet of Things Programming with JavaScript

Overview of this book

The Internet of Things is taking the tech world by storm, and JavaScript is at its helm. This book will get you to grips with this exciting new technology. Where do Node.js, HTML5 and Windows 10 IoT Core come in with JavaScript and IoT? Why Raspberry Pi Zero rather than Arduino? How do you configure and build an IoT network from scratch?

Preface

Configuring a web server


There are several web servers available that we can install on your Raspberry Pi. We're going to install the lighttpd web server. Also, we need to install PHP support, which will help us run a website into our Raspberry Pi and have dynamic web pages.

To install and configure, log in to the Raspberry Pi via the terminal console of PuTTY:

  1. Update the package installer:

            sudo apt-get update
    
  2. Install the lighttpd web server:

            sudo apt-get install lighttpd
    

Once installed, it will automatically start up as a background service; it will do so each time the Raspberry Pi starts up:

  1. To set up our PHP 5 interface for programming with PHP 5, we need to install the PHP5 module support with the following command; this is necessary to have our server, and it can execute PHP files so that we can make our website:

            sudo apt-get install php5-cgi
    
  2. Now we need to enable the PHP FastCGI module on our web server:

            sudo lighty-enable-mod fastcgi-php
    
  3. For the last step, we have to restart the server with the following command:

            sudo /etc/init.d/lighttpd
    

In the following screenshot, we show the content of the page that will to appear when we configure the web server and the PHP 5 interface. The web server installs a test placeholder page in the location /var/www. Type the IP address of your Raspberry Pi in the browser, for example, http://192.168.1.105/, and the following screen appears, opening the active page of the configured server:
