1. Download cassandra
2. Configure export CASSANDRA_HOME=/home/test/local/cassandra
3. configure $CASSANDRA_HOME/conf/cassandra.yaml as follows:

cluster_name: '[Your Cluster Name]'
listen_address: [public_ip_address]
rpc_address: [public_ip_address]
endpoint_snitch: GossipingPropertyFileSnitch
seed_provider:
    # Addresses of hosts that are deemed contact points. 
    # Cassandra nodes use this list of hosts to find each other and learn
    # the topology of the ring.  You must change this if you are running
    # multiple nodes!
    - class_name: org.apache.cassandra.locator.SimpleSeedProvider
    parameters:
        # seeds is actually a comma-delimited list of addresses.
        # Ex: "<ip1>,<ip2>,<ip3>"
        - seeds: "127.0.0.1,192.168.72.163,192.168.72.162"
auto_bootstrap: false

5. rm -rf $CASSANDRA_HOME/data/data/system/* if you installed a cluster before
