我正在尝试连接到 cassandra。我安装了最新的稳定版本 apache-cassandra-1.2.4 并将其解压缩到我的桌面上。当我运行 cassandra 时，它会很好地监听 thrift 客户端并显示以下内容：

现在当我运行：cassandra-cli -h localhost -p 9160 时，它会抛出错误。我检查了端口是否空闲，并且 cassandra 正在监听该端口。：

我有同样的错误。现在，没关系。

主要问题是配置错误。

我的配置如下：

我的视觉机器ip是192.168.11.11。我的cassandra安装到机器上。所以，我配置thar

listen_address: 192.168.11.11
rpc_address: 0.0.0.0
broadcast_rpc_address: 192.168.11.11

没关系。</p>

cassandra-stress 的文档似乎很粗略。也许在适当的时候会得到纠正。截至目前，这个命令对我有用

./cassandra-stress write -node <IP_OF_NODE1>

一旦这工作，我们可以尝试输入其他可选参数来调整我们的命令。

选项1：

Run jps command under root user and kill CassandraDaemon if you will see it. After this you will start Cassandra again.

选项2： 

Try to connect Cassandra with CQL 
  ./cqlsh 10.234.31.232 9042

最终检查：

An intermediate firewall is blocking the JVM from making the connection. 
An operating system firewall, or antivirus that is causing the problems as well.

我认为您安装在 Windows 中，并且看起来防火墙阻止了您的连接。
