Welcome to our series of blog posts that will guide you through the installation of the PostgreSQL database server on a Raspberry PI single board computer.
In this article we will cover what you need to do before actually starting to use your Raspberry.
In this first post, we will go over the preliminar requirements for the set up of a Raspberry PI system in a private network (LAN). This is all you need to get started:
- An Ethernet cable
- A LAN router/switch
- A Raspberry PI
- A SDHC storage device (SD)
- A PC with SD card reader (just for the first time)
For this set up we used a kit including the Raspberry PI (RAM 512MB), the 1.2A power supplier, and a transparent case. It contained also a 8GB SD card class 10 (30 MB/s).
For the installation, an USB keyboard and an USB mouse are needed too.
IMPORTANT: As far as video is concerned, Raspberry supports both analogic or HDMI video output. In our example we have used an existing display/monitor supporting HDMI input: all we needed was an HDMI cable. Do not panic if you do not have a HDMI display: given that you need a directly attached display just for the time of the installation, you can even plug your Raspberry to your TV, using a standard RCA composite video cable.
Buying a Raspberry PI
We ordered the material listed above from Amazon. Few days are required for the delivery. Here is a list of the costs:
- Raspberry PI kit (Raspberry PI + power supplier + case + SD): 66.70€ (delivery costs included)
- USB keyboard + USB mouse: 25.26€ (delivery costs included)
- HDMI cable: 5.99€ (optional)
We have not included the cost of the HDMI monitor: anyway, as mentioned before, it is needed only for the initial setup of both the operating system and the network.
In the next article, we will go through the setup of the components we bought.
 Raspberry PI requires an at least 4GB SD card, with 2GB dedicated to the operative system (see the Raspberry official page).
