title: Cassandra - What's the relation between 'start_rpc' and 'rpc_address' in cassandra.yaml
body: <p>I'm using cassandra 3.6.</p>
  
  <p>The names seem to implying me that I need to enable <code>start_rpc</code> before set <code>rpc_address</code>. </p>
  
  <p>I try disable <code>start_rpc</code> and set <code>rpc_address</code> to my local network address <code>192.168.201.144</code> ,my cluster is still working but I need to use <code>CQLSH_HOST=192.168.201.144 apache-cassandra-3.6/bin/cqlsh</code>  in order to connect to cassandra.</p>
  
  <p>What's the relation between them?</p>
