How To Install Cassandra and Run a Single-Node Cluster on Ubuntu 14.04
Introduction
Cassandra, or Apache Cassandra, is a highly scalable open source NoSQL database system, achieving great performance on multi-node setups.
In this tutorial, you’ll learn how to install and use it to run a single-node cluster on Ubuntu 14.04.
Prerequisite
To complete this tutorial, you will need the following:
Installing Cassandra
We'll install Cassandra using packages from the official Apache Software Foundation repositories, so start by adding the repo so that the packages are available to your system. Note that Cassandra 2.2.2 is the latest version at the time of this publication. Change the 22x to match the latest version. For example, use 23x if Cassandra 2.3 is the latest version:
echo "deb http://www.apache.org/dist/cassandra/debian 22x main" | sudo tee -a /etc/apt/sources.list.d/cassandra.sources.list
The add the repo's source:
echo "deb-src http://www.apache.org/dist/cassandra/debian 22x main" | sudo tee -a /etc/apt/sources.list.d/cassandra.sources.list
To avoid package signature warnings during package updates, we need to add three public keys from the Apache Software Foundation associated with the package repositories.
Add the first one using this pair of commands, which must be run one after the other:
gpg --keyserver pgp.mit.edu --recv-keys F758CE318D77295D
gpg --export --armor F758CE318D77295D | sudo apt-key add -
Then add the second key:
gpg --keyserver pgp.mit.edu --recv-keys 2B5C1B00
gpg --export --armor 2B5C1B00 | sudo apt-key add -
Then add the third:
gpg --keyserver pgp.mit.edu --recv-keys 0353B12C
gpg --export --armor 0353B12C | sudo apt-key add -
Update the package database once again:
sudo apt-get update
Finally, install Cassandra:
sudo apt-get install cassandra
