I have a RPi Model B and a RPi 2 (works great as a Kodi media center!), but just for fun I ordered a RPi Model A+ to check it out.

In common with the B+ and RPi 2, the A+ has the enchanced 40-pin GPIO header, so it's well suited to being used as a project board (in contrast to being used as a desktop GUI).  Unlike it's bigger sibling, the 512 MB Model B+, the A+ has 256 MB of RAM.

Advantages:

  • Smaller size, more compact
  • Lighter weight
  • Less power usage, runs longer on battery power
  • HAT compatible form-factor
  • Lower cost, the least expensive of all the RPi models

One of the more handy programs (which is still free of charge) for trying out different Linux distributions is Oracle's VirtualBox. There is a small learning curve to get acquainted with virtualiztion, but still a good program. 

One of the first issues that needs to be addressed is the default 640x480 screen resolution after installing a VM.  Turning to Google, there are lots of posts about how to fix this, most of them outdated and addressing older versions of VirtualBox.  For the remainder of this post, I'll be talking about VirtualBox version 4.3.26.

The LAMP stack is Linux, Apache, MySQL and PHP and used for web hosting. Installing on your local workstation for development and testing can be done from the command line.


  • Open the terminal with Control-Alt-t
  • Use the apt-get package manager commands to update your system:

    sudo apt-get update && sudo apt-get upgrade
     
  • Then install the LAMP stack:

    sudo apt-get install lamp-server^

    (you will need to create an admin password for MySQL during installation, be sure to write that down for later).
    Note the ^ is required at the end of the command
  • To easily manage your MySQL server from a web brower, install phpMyAdmin:

    sudo apt-get install phpmyadmin

    (you will need that MySQL admin password from the previous step)

 Additional note: these instructions are for a local development installation of LAMP and does not include instructions for hardening.  For a production installation further due diligence would be needed for security.  See this article: How to Secure Ubuntu for the Web

Raspberry Pi 2 as a Media Center

With all the excitement being generated with the new Raspberry Pi 2 (RPi2 for short), I started looking for the best OS to use the new RPi2 as a media center. Looks like some things have changed since I researched this before in 2014.

For starters, the best way to install an OS on your SD card is using NOOBS (New Out Of Box Software). Your choices are Rasbian (recommended for beginners), Archlinux, Pidora, OpenELEC and RaspBMC, which includes the XBMC media center software which runs on the model A, B and B+.  However, RaspBMC won't be supported for the new RPi2 and is changing to OSMC (which will support RPi2 in the Alpha 4 release). Secondly, XBMC is changing to Kodi, which will support the RaspB 2.  On top of that, there's another XBMC/Kodi distribution called XBian, which will run on the RPi2.

While anxiously awaiting the arrival of my new Raspberry Pi 2 from The Pi Hut, I was checking out some of their tutorials.  This one is very useful, discussing how to see what's included in the installation and adding new programs with the package manager.
