如何使用 cqlsh 将 Cassandra 连接到本地主机? [英] How to connect Cassandra to localhost using cqlsh?

问题描述

我将 rpc_port 设置为公共 IP 地址，现在我可以从外部服务器很好地连接到 Cassandra.

I set rpc_port to the public IP address, and now I can connect to Cassandra just fine from an outside server.

但是，我无法使用 cqlsh 从 Cassandra 服务器本身进行连接

However, I cannot connect from the Cassandra server itself, using cqlsh

我收到一个错误.Thar是:

I am getting an error.Thar are:

 Connection error: Could not connect to localhost:9160

是否有配置，我可以更改为能够从服务器本身连接?

Is there a configuration, I can change to be able to connect from the server itself ?

推荐答案

1. 检查cassandra.yaml 文件与rpc_port : 通常默认= 9160
2. 登录到托管 cassandra
的机器
3. 试试 cqlsh 127.0.0.1 9160 :无论如何应该没问题
4. try cqlsh [IP of host] 9160 : 如果正常，则 cassandra 可从局域网访问，如果正常，则 cassandra 无法从 lan 但只有 localhost 127.0.0.1

1. Check the cassandra.yaml file on the line with rpc_port : normally by default = 9160
2. Login to the machine hosting cassandra
3. Try cqlsh 127.0.0.1 9160 : should be ok in any case
4. try cqlsh [IP of host] 9160 : if ok then cassandra reachable from lan, if ok then cassandra is not reachable from lan but only localhost 127.0.0.1
