DreamFactory can be installed and configured on Raspberry Pi 2 as an open source IoT gateway.
Since DreamFactory relies on PHP and Laravel frameworks, the existing Raspbian distribution needs to be upgraded from Wheezy to Jessie. The upgrade process involves some manual work, including updating the package sources for Jessie and building PHP 5.6 from the sources. [Ubuntu Mate](https://ubuntu-mate.org/) is a stable, easy-to-use Debian distribution that can run on Raspberry Pi 2. Since it comes with PHP 5.6, it is easy to install all the required dependencies through simple apt-get install commands.
Here is a step-by-step guide to install DreamFactory on Raspberry Pi 2.
- Install Ubuntu Mate on Raspberry Pi 2
Follow the same procedure as setting up Raspbian for installing Ubuntu Mate on Raspberry Pi 2. Download the [image](https://ubuntu-mate.org/raspberry-pi/), uncompress it, and write it to a SD card. You can take the help of [Pi Filler](http://ivanx.com/raspberrypi/) to burn the .img file to the SD card. Boot Raspberry Pi with the SD card and follow the on-screen instructions. Make sure that the operating system is successfully installed.
