问题描述
我刚刚开始使用Cassandra（datastax），版本2.1.3和cqlsh版本5.0.1。
I've just started working with Cassandra (datastax), version 2.1.3 and cqlsh version 5.0.1.
Cassandra启动正常，
Cassandra starts up fine and the cluster is operational instantly.
Cqlsh不工作（在任何节点上），并发出以下错误：
Cqlsh is not working (on any of the nodes) and emits the following error:
我已经尝试启动cqlsh与主机自己的ip，其他主机ip，不同的端口
I have tried starting cqlsh up with the hosts own ip, other hosts ip, different ports yet the result remains the same - always connection refused.
推荐答案
尝试更改 rpc_address 指向节点的IP而不是0.0.0.0，并在连接到cqlsh时指定IP，如同IP是10.0.1.34和 rpc_port 左到默认值9160，那么以下应该工作：
Try to change the rpc_address to point to the node's IP instead of 0.0.0.0 and specify the IP while connecting to the cqlsh, as if the IP is 10.0.1.34 and the rpc_port left to the default value 9160 then the following should work:
cqlsh 10.0.1.34 9160
或：
cqlsh 10.0.1.34
