Raspberry Pi for N00bs – Minecraft Server

While the older Raspberry versions (A/B/B+) may not be up for the task, you can easily use the Raspberry 2 for a Minecraft server. At least 5 concurrent users are no problem at all, depending on your bandwidth. My Raspberry 2 did not use more than 300% CPU in a test, which is actually 75% – most of the time it was even below 200% (=50% on the Raspberry 2). It seems that Minecraft scales well over the 4 cores, at least with the version i am using.

Raspberry Pi for N00bs – WLAN

So you already know how to connect to the LAN, but sometimes the Router is not right next to the Raspberry Pi and you need a wireless connection. Not every WLAN stick is compatible, check the compatibility list before you buy one. I am using a TP-LINK 150Mbps Nano, no additional driver needed and you almost don´t see it when it´s in the Rasbperry. With “ifconfig“, you can see if the WLAN stick is up and running with the correct driver:

Raspberry Pi For N00bs – Linux Basics

After installing a Linux distribution as explained in my article “Raspberry Pi for n00bs – Installation“, it is time to change some basic settings. This article covers everything you need to know to get your system ready to use. I only run my Raspberries “headless”, without a monitor/TV.

Raspberry Pi for N00bs – Installation

A complete PC for only 30 Euros, super-silent without active cooling, the operating system on SD card. That is the Raspberry Pi 🙂

Shopping List

…ok, to get it up and running, you will need a few more Euros, here´s the minimal configuration:Raspberry Pi Logo

  • Raspberry Pi – B/B+ (30-35 Euros)
  • Ethernet cable (1-2 Euros)
  • Power supply with at least 0,7A (better 1A) and Micro USB (5-10 Euros)
  • One of the countless Raspberry cases (5-10 Euros)
  • SD card with at least 4GB, better 8 or 16 (10-20 Euros)

Now we´re already at ~50 Euros, but the Mini-PC only needs 2-3 Watts and practically no space.

A HDMI cable and a USB keyboard are optional, for the first installation and if you don´t just want to administrate the Raspberry Pi with SSH. Check your local supplier for all the items, SD cards are pretty cheap at Amazon. It´s a good idea to check the compatibility list first: http://elinux.org/RPi_SD_cards
