Cassandra public IP not connecting

I'm using cassandra in ubuntu server. when I try to connect using CLI with public IP address, It returns connection refused. whereas If I tried with localhost, its working fine. I made the configuration changes in cassandra.yaml and storage-conf.xml. but still I have the problem. Wha开发者_开发问答t change should be done ?

Thanks in advance..

s..I have connecting the server using ssh.

Changing localhost to 0.0.0.0 in cassandra.yaml is not always work. In case of JVM Implementation is different ,it wont work

Checkcassandra-env.shfile and make this entry at last along with JVM_OPTS options

JVM_OPTS="$JVM_OPTS -Djava.rmi.server.hostname=here your IP"

Have you checked your firewall settings on the server to make sure connections are allowed to Cassandra?

vi conf/cassandra.yaml and edit localhost to 0.0.0.0
