kafka.zookeeper.ZooKeeperClientTimeoutException：处于状态时等待连接超时：正在与远程主机连接

Question

我在我的一个云服务器实例中安装了一个 Zookeeper 和一个 Kafka 代理服务器，它们运行良好。但是当尝试连接到远程 Zookeeper 服务器时，Kafka 代理无法访问该 IP 地址和端口号。防火墙也处于非活动模式。

总结为：

one zookeeper server - in cloud instance [146.646.64.66*]
one Kafka broker server - in cloud instance [146.646.64.66*]
two Kafka broker server - in my local PC [localhost]

我更新了本地 Kafka 代理服务器属性文件的 zookeeper.connect 属性如下：

zookeeper.connect=146.646.64.66*:2181

以下是CMD显示的错误：

请帮我解决这个问题。

删除所有缓存的日志文件或更改您要运行的server.properties 文件的日志路径目录。由于您的服务器历史记录，缓存日志文件的数据可能会受到影响。
