=== Step 2.2: Configure Memory Usage (Optional) ===
By default, Cassandra will allocate memory based on physical memory your system has, using somewhere between 1/4 and 1/2 of the available RAM.

== Step 3: Start Cassandra ==
- And now for the moment of truth, start up Cassandra by invoking `bin/cassandra -f` from the command line<<FootNote(To learn more about controlling the behavior of startup scripts, see RunningCassandra.)>>. The service should start in the foreground and log gratuitously to the console. Assuming you don't see messages with scary words like "error", or "fatal", or anything that looks like a Java stack trace, then everything should be working.
