Overview of this book

There’s no end to what you can do with a Raspberry Pi – it makes a huge range of tech projects possible. This book shows you how to transform it into a multipurpose web server, able to store and manage resources that lets you build some truly innovative and impressive computing creations. You’ll learn how to use your Raspberry Pi 2 to host a website using a range of different languages, host a game server, store files, and run everything from a media center to a cloud network. If you want to take control of your technological world, start building your own server and find out what’s possible with the Raspberry Pi microcomputer. Begin by getting your Pi set up – follow each step as the book shows you how to prepare a network and configure the additional features that you’ll need to build your projects. Once you’ve done this you’ll dig a little deeper and set up your pi as a file server, making sure it’s built for speed using a range of different tools, including Python, Node.js and ASP.NET. Following this the book shows you how to extend your server to allow you to host games, and stream live HD video before customizing it even further to create a fully-fledged media center. It doesn’t stop there however – the book then dives into the exciting world of the Internet of Things (IoT). You’ll learn how to install Windows IoT onto your Raspberry Pi, the operating system that’s driving embedded software projects all around the world. Once you’ve done this you’ll be ready to explore IoT further, as the book shows you how to use your device to host a cloud network that can form the basis of a wider IoT project.

Hardware monitoring

The Raspberry Pi Foundation provides a tool called vcgencmd, which gives you detailed data about various hardware used in the Raspberry Pi. This tool is updated from time to time and can be used to log the temperature of the GPU, voltage levels, processor frequencies, and so on. Some commands for monitoring are as follows:

  • To see a list of supported commands, we type the following in the console:

    vcgencmd commands
  • As newer versions are released, there will be more commands available here. To check the current GPU temperature, we will use the following command:

    vcgencmd measure_temp
  • We can use the following command to check how RAM is split between the CPU and GPU:

    vcgencmd get_mem arm/gpu
  • To check the firmware version, we can use the following command:

    vcgencmd version

The output of all these commands is a simple text that can be parsed and displayed on a website or stored in a database.
