Now that you have a single node setup, you may start Cassandra by executing <cassandra_installation>/bin/cassandra for a tarball install or by running sudo service cassandra start for a repository install. (We'll see later in this chapter how to write a .init script for Cassandra and set it up to start on boot.) However, in order to get a Cassandra cluster working, a couple of configuration tweaks are required.
