C# 建立一个卡夫卡制作人立即产生效果”；请求ApiVersion时断开连接”；错误

我下载了《卡夫卡》2.13-2.5.1，将其解压缩到一个文件夹中，编辑了《制作人属性》，以实现快速压缩，剩下的就剩下了。我用命令启动任何东西（服务器？集群？他妈的知道）

bin/windows/zookeeper-server-start.bat config/zookeeper.properties

它启动并显示它正在监听端口2181：

INFO binding to port 0.0.0.0/0.0.0.0:2181 (org.apache.zookeeper.server.NIOServerCnxnFactory)

在我的C#代码中，我创建了一个错误处理程序：

void KafkaErrorHandler(IProducer<Null, string> producer, Error error)
{
    Console.WriteLine(error.Reason);
}

如果我将

SecurityProtocol=SecurityProtocol.Ssl，

添加到producer config，则会出现以下错误：

{ssl://localhost:2181/bootstrap: SSL握手失败：断开连接：连接到明文代理侦听器？（在连接状态下2毫秒后）}

它还需要什么来下定决心并开始工作

我使用zookeeper服务器启动启动

卡夫卡控制台窗口

那是动物园管理员服务器，不是卡夫卡

您需要一个单独的窗口来启动带有
config/server.properties
文件的
kafka服务器启动

然后，您的代码将使用端口9092（默认情况下），正如您在显示的代码中所评论的那样

如果我将SecurityProtocol=SecurityProtocol.Ssl添加到producer config，则会出现以下错误

据我所知，您从未在Kafka服务器中设置任何SSL属性，因此不会改变任何内容
我还恢复了100%普通配置，如OOB，并从producer config中删除了压缩。他不工作了。不同的警告。尝试端口9093。不起作用。“zookeeper”和“服务器”的用途是什么？为什么“zookeeper”启动脚本说它是“服务器”启动脚本？我可能建议阅读卡夫卡（和zookeeper）文档，但它的主要职责是领导人选举/容错/元数据存储。脚本会启动Zookeeper服务器；不知道你在找什么
kafkaProducerConfig = new ProducerConfig
{
    CompressionType = CompressionType.Snappy,
    BootstrapServers = "localhost:2181", // Docs said 9092 plain, 9093 SSL. Huh?
    ClientId = Dns.GetHostEntry(Environment.MachineName).HostName
};

var pb = new ProducerBuilder<Null, string>(kafkaProducerConfig);
pb.SetErrorHandler(KafkaErrorHandler);
kafkaProducer = pb.Build();
