Question

当我尝试连接到10.0.0.60 9042时，出现错误：

[idf@node1 conf]$ cqlsh 10.0.0.60 9042
Connection error: ('Unable to connect to any servers', {'10.0.0.60': TypeError('ref() does not take keyword arguments',)})

但是，我可以看到cassandra正在侦听该端口。 不确定发生了什么？

Answer 1

尝试访问cqlsh，如下所示：

   [idf@node1 conf]$ cqlsh 10.0.0.60
      OR
   [idf@node1 conf]$ cqlsh `hostname -i`

默认端口rpc_port为9160,9542为native_transport_port。

cassandra在主机端口上侦听，但无法连接
