I have installed the Cassandra 1.2.9 into my vps server which is having CentOs. I have Installed it successfully. when i run the sh cassandra-cli, i got the error message 

org.apache.thrift.transport.TTransportException: java.net.ConnectException: Connection refused

Exception Connecting to 127.0.0.1/9160. Reason: Connection refused?.

I have checked the jps command and try to kill jps process. ex: kill 9557. Unfortunately again i got the error message likewise, -bash: kill :9557 no such process.

Please, advice me...

    `Connection refused` generally means nothing is listening on the relevant port. Did you start the server process ? – user9517 Oct 05 '13 at 08:35
  • In this version (Cassandra 1.2.9), there is no option to start the cassandra service. i have searched the bin folder too. – Nagaraj Oct 05 '13 at 10:05

try ps aux | grep cassandra to see if cassandra is running, for debugging this issue try running Cassandra in forground, in ubuntu I just do cassandra -f to start it in foreground and if there is any issue in cassandra config etc it will tell you here, if it starts fine then open another terminal and try to connect again, I think Cassandra is not running in your case that is why you are getting a connection refused.

After getting this error , type connect listen_address/9160; on your console

where listen address is the address mentioned in your conf/cassandra.yaml file.
