Understand the default configuration

The Cassandra admin user for all databases is automatically generated. The administrator user name is cassandra and you can get the password from the server dashboard for your server.

You can connect to the Cassandra server locally or remotely using the cqlsh command line tool:

$ cqlsh -u cassandra
Password:
Connected to Test Cluster at 127.0.0.1:9042.
[cqlsh 5.0.1 | Cassandra 2.1.1 | CQL spec 3.2.0 | Native protocol v3]
Use HELP for help.

The Cassandra server is configured to accept incoming connections on the default Cassandra client port 9042. This could be a security issue so it is strongly advisable to close this port or open it only for a specific IP address. Other ports for configuring nodes are closed by default in the firewall.
