Running Cassandra

With the configuration complete, start up your node.

If you used the Tarball install:

bin/cassandra -p cassandra.pid

Note

It is not recommended to run Cassandra as the root user or as a user with access to sudo. You should create a Cassandra user, and ensure that Cassandra runs as that user instead.

If you used apt-get for the install:

sudo service cassandra start

Cassandra comes with the nodetool utility, which is very useful for performing operational duties, as well as for assessing the health of your node and/or cluster. To verify that your node has started, running a nodetool status should return information on your cluster, based on the gossip information held by the node that you are logged into:

nodetool status
