CassandraCluster

A project using Vagrant and Ansible to create and deploy a Cassandra Cluster with VirtualBox.

By default a 5-Node Cassandra Cluster will be created each with 2GB of RAM and 1 cpu.

Requirements

  • vagrant 1.9.0
  • virtualbox 5.0.26 r108824
  • ansible 2.2.0.0
  • git version 2.11.0

Getting Started

git clone https://github.com/rhysmeister/CassandraCluster.git
cd CassandraCluster
vagrant up

Access the Cassandra Cluster Nodes

View the status of nodes:

vagrant status;

Current machine states:

cnode1                    running (virtualbox)
cnode2                    running (virtualbox)
cnode3                    running (virtualbox)
cnode4                    running (virtualbox)
cnode5                    running (virtualbox)

To access a node via ssh;

vagrant ssh cnode1

One inside the host we can view the status of the Cassandra Cluster with nodetool;

[vagrant@cnode1 ~]$ nodetool status
Datacenter: datacenter1
