1.Update：./conf/cassandra.yaml

rpc_address: 0.0.0.0 ("0.0.0.0" allow anywhere IP,but you can appoint an IP)

\# broadcast_rpc_address: 1.2.3.4 (Delete comment if rpc_address=0.0.0.0)

2.restart

./bin/cassandra

Answer 2

I got the same issue. And I am following answer in this post. Unfortunately, I have no luck to make it work. I did some research. And it works now. Here is my change.

• Environment Ubuntu Server 16.04.3 LTS on VirtualBox, DSE version 5.1

• Install DSE

I am installing DSE follow this page https://docs.datastax.com/en/dse/5.1/dse-dev/datastax_enterprise/install/installGUIdse.html

• Go to /etc/dse/cassandra/cassandra.yaml
• Change 'seeds' from 127.0.0.1 to {seriver ip} exp. mine is 172.20.10.9
• listen_address In DSE 5.1 official document says 'Never specify 0.0.0.0; it is always wrong.' What I did is comment out 'listen_address' setting
• 'rpc_address' change from localhost to 0.0.0.0
• 'broadcast_address' change to server IP. Mine is 172.20.10.9
• 'broadcast_rpc_address' change to server ip
• restart dse wait for couple minute,it is changing. If still not work, restart machine.

This is my log in 15 seconds. `ubuntu08@ubuntu08:~$ nodetool status nodetool: Failed to connect to '127.0.0.1:7199' - ConnectException: 'Connection refused (Connection refused)'. ubuntu08@ubuntu08:~$ nodetool status

Error: The node does not have system_traces yet, probably still bootstrapping ubuntu08@ubuntu08:~$ nodetool status

• I can access by run 'cqlsh 172.20.10.9' from local or another machine.
