Elasticsearch on a Raspberry Pi

I’m posting this as a step-by-step on installing Elastic Search on a Raspberry Pi. While I don’t honestly think having a cluster of Raspberry Pi computers running Elastic Search is a true enterprise solution, I think there could be something to this in the future. As cheap as hardware keeps getting, it’s entirely reasonable to believe that a myriad ARM-based Systems-on-a-Chip (SOC) could be a completely feasible cluster solution. Today you can pay $40 for a single little Raspberry Pi. If you forked out $4000, you could have 100 of these tiny machines all running Elastic Search in memory. What does one VM slice cost an enterprise right now? Just sayin’…
Format your SD card (I used a 32GB, a 64GB card would be nice) using this formatter.
Download NOOBS for Raspberry Pi here.
Copy the files to the card, insert into the Raspberry Pi, and boot.
When prompted, choose to install Raspbian.
After install is complete, reboot to command line (bash shell)
Install Oracle Java (7, at the time of this posting), using “sudo apt-get update && sudo apt-get install oracle-java7-jdk”
Create a directory to store Elastic Search using “sudo mkdir /usr/share/elasticsearch”.
Change to the directory using “cd /usr/share/elasticsearch/elasticsearch-0.90.7”.
Download Elastic Search (v0.90.7 at the time of this posting), using “http://download.elasticsearch.org/elasticsearch/elasticsearch/elasticsearch-0.90.7.tar.gz”. Please note you may have to change the file name if the version has increased since this article.
Extract the zipped file: “sudo tar -zxvf elasticsearch-0.90.7.tar.gz”
Delete the archive: “sudo rm elasticsearch-0.90.7.tar.gz”.
Run Elastic Search! “sudo bin/elasticsearch”
Verify the install: “curl -XGET http://localhost:9200/”
Install the _head plugin: “sudo bin/plugin -install mobz/elasticsearch-head”.
Get your local IP address: “sudo ifconfig”. Look for “inet addr”. Copy your IP address.
From any browser on the network, navigate to “http://[your Raspberry Pi IP]:9200/_plugin/head/”.
Start searching!
Hope it helps!
