Overview of this book

With the release of the Raspberry Pi 2, a new series of the popular compact computer is available for you to build cheap, exciting projects and learn about programming. In this book, we explore Raspberry Pi 2’s hardware through a number of projects in a variety of programming languages. We will start by exploring the various hardware components in detail, which will provide a base for the programming projects and guide you through setting up the tools for Assembler, C/C++, and Python. We will then learn how to write multi-threaded applications and Raspberry Pi 2’s multi-core processor. Moving on, you’ll get hands on by expanding the storage options of the Raspberry Pi beyond the SD card and interacting with the graphics hardware. Furthermore, you will be introduced to the basics of sound programming while expanding upon your knowledge of Python to build a web server. Finally, you will learn to interact with the third-party microcontrollers. From writing your first Assembly Language application to programming graphics, this title guides you through the essentials.

Popular web servers available on the Raspberry Pi


Depending on the type of application you wish to serve up, a variety of programs are available to download for free. In this chapter, we will look at two popular open source web servers, Apache and NGINX.

Apache

Apache has been around for a long time and is a well-known web server. You can read about its history at http://www.apache.org/.

To install it onto Raspbian we can use apt-get. Run the following command:

sudo apt-get install apache2 –y

This will kick off the installation process.

Once complete, we can test it works by visiting localhost in our web browser on the Raspberry Pi or by visiting the IP address of the device from a second computer, for example http://<ip of rpi>/.

Tip

If you find the web server is not running, you can use the following command:

sudo apache2ctl –k start

By default, an index.html page is included with the web server.

To add our own HTML files to Apache, we can place these in:

/var/www/html

Rename the existing...
