I’ve started a new project to create a Cassandra Cluster for development purposes. It’s available on my github and uses Vagrant, Ansible, and VirtualBox.

Assuming everything is installed it’s quite easy to get started;

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

Check the status of the machines;

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

The Administrator credentials for Cassandra are set in the cassandra.yml file and can be modified.

See the following variables;

cassandra_admin_user
