Cassandra-cli cant connect to remote cassandra server

Question

I have a cassandra server running on a server(serv1). cassandra-cli can connect to it when run on serv1. However, when i try to connect to it through some other server(serv2), i get the following exception:

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

Exception connecting to jckstore/9160. Reason: Connection refused.

I looked in cassandra.yaml and found that the property "listen_address" is configured to "localhost" and using 0.0.0.0 is severely discouraged. I tried to change localhost to serv2, ip address of serv1 but nothing worked. Even commenting out didnt help.

Is there a way i can make my cassandra server listen on all the ip's without using 0.0.0.0

Answer 1

I was able to solve the problem as following:

1. changing the rpc_address property in cassandra.yaml to 0.0.0.0 instead of localhost.
2. set the broadcast_rpc_address property in cassandra.yaml to a value other than 0.0.0.0

Then I can access.
