Introduction

Apache Cassandra is a highly scalable open source database system, achieving great performance on multi-node setups.

Previously, we went over how to run a single-node Cassandra cluster. In this tutorial, you’ll learn how to install and use Cassandra to run a multi-node cluster on Ubuntu 14.04.

Prerequisites

Because you’re about to build a multi-node Cassandra cluster, you must determine how many servers you’d like to have in your cluster and configure each of them. It is recommended, but not required, that they have the same or similar specifications.

To complete this tutorial, you’ll need the following:

• At least two Ubuntu 14.04 servers configured using this initial setup guide.
• Each server must be secured with a firewall using this IPTables guide.
• Each server must also have Cassandra installed by following this Cassandra installation guide.
