Cassandra cqlsh - 连接被拒绝 [英] Cassandra cqlsh - connection refused

问题描述

我刚刚开始使用 Cassandra (datastax) 2.1.3 版和 cqlsh 5.0.1 版.

I've just started working with Cassandra (datastax), version 2.1.3 and cqlsh version 5.0.1.

Cassandra 启动良好，集群立即运行.

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:

连接错误:('无法连接到任何服务器'，{'127.0.0.1':错误(111，尝试连接到 [('127.0.0.1', 9042)].最后一个错误:连接被拒绝")})

Connection error: ('Unable to connect to any servers', {'127.0.0.1': error(111, "Tried connecting to [('127.0.0.1', 9042)]. Last error: Connection refused")})

我尝试使用主机自己的 ip、其他主机的 ip、不同的端口启动 cqlsh，但结果仍然相同 - 始终拒绝连接.

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

您需要在您尝试连接的节点上编辑 cassandra.yaml 并为 设置节点 IP 地址rpc_address 和 listen_address 并重新启动 Cassandra.

You need to edit cassandra.yaml on the node you are trying to connect to and set the node ip address for rpc_address and listen_address and restart Cassandra.

rpc_address 是 Cassandra 监听客户端调用的地址.

rpc_address is the address on which Cassandra listens to the client calls.

listen_address 是 Cassandra 侦听其他 Cassandra 节点的地址.

listen_address is the address on which Cassandra listens to the other Cassandra nodes.
