In part one I wrote an article about setting up Docker for Cassandra. Now Docker will act as a server so you still can't add your own keyspace or doing any queries.

I really recommend using homebrew to make your life easier. You could install homebrew in here.

Setting cassandra on host

Now to install Cassandra on your host, run this command in terminal:

brew install cassandra

In case you don't have python installed, also run this command:

brew install python

And cql library for python:

pip install cql

Enter cqlsh on Docker

Remember to start your docker first:

docker-compose up

To enter cqlsh:

cqlsh [your docker ip]:[your cassandra port]

Example:

cqlsh 192.168.59.103:9042

To know your docker ip on Mac:

boot2docker ip

Create keyspace on Cassandra

Keyspace is like database on traditional SQL. To create keyspace in Cassandra:

CREATE KEYSPACE demo WITH REPLICATION = {'class': 'SimpleStrategy', 'replication_factor':1 };

To do queries on the keyspace you have just created:

USE demo;

Yup, that's it for the Cassandra introduction. Another great article you should read:
