如何連接到羣集prommatically

Question

上午成功安裝cassandra，當我用「connect localhost/9160;」這是工作的罰款我。我想用不同的IP地址進行連接測試/ Port.I被更改listen_address在cassandra.yaml文件並重新啓動服務器並測試它顯示下面的錯誤。

這實在是有幫助的me.Sorry我的英語不好..

如果更改的唯一參數是listen_address，那麼你還需要使用端口9160與卡桑德拉-CLI連接。如果您還想更改該端口，則需要相應地調整cassandra.yaml中的rpc_port。 listen_address定義兩個Cassandra節點通過的端口。它獨立於用於Thrift客戶端的端口（如cassandra-cli）。
