如何使用cqlsh连接Cassandra到localhost？

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，我无法从Cassandra服务器本身，使用cqlsh

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

我得到一个错误.Thar是：

I am getting an error.Thar are:

 Connection error: Could not connect to localhost:9160

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


2. 尝试cqlsh 127.0.0.1 9160：在任何情况下都应该确定
/ li>

3. 尝试cqlsh [主机的IP] 9160：如果确定然后cassandra可从lan，如果ko然后cassandra不能从lan到达只有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 ko then cassandra is not reachable from lan but only localhost 127.0.0.1
