带有SSL的Apache Kafka正在工作，但Kafka日志中针对本地主机的SSL错误（让我发疯）

ssl apache-kafka

带有SSL的Apache Kafka正在工作，但Kafka日志中针对本地主机的SSL错误（让我发疯）,ssl,apache-kafka,kafka-producer-api,Ssl,Apache Kafka,Kafka Producer Api,我有一个卡夫卡问题，这让我发疯 我们有一个4节点集群。我们在开发阶段通常不使用SSL。-->没问题 在发布时，我们为两个侦听器都启用了SSL。-->一切正常（应用程序+卡夫卡管理器CMAK+监控） 但我们在所有环境（测试、发布、生产）中的kafka broker服务器日志中都有一个错误。有些东西是投票，我不知道它是什么，也不知道去哪里看： 开头是： [2020-10-16 10:50:27,866] INFO AdminClientConfig values: bootstrap

我有一个卡夫卡问题，这让我发疯

我们有一个4节点集群。我们在开发阶段通常不使用SSL。-->没问题

在发布时，我们为两个侦听器都启用了SSL。-->一切正常（应用程序+卡夫卡管理器CMAK+监控）

但我们在所有环境（测试、发布、生产）中的kafka broker服务器日志中都有一个错误。有些东西是投票，我不知道它是什么，也不知道去哪里看：

## Metrics Reporter Configuration
confluent.metrics.reporter.security.protocol=SSL
confluent.metrics.reporter.ssl.truststore.location=LOCATION
confluent.metrics.reporter.ssl.truststore.password=PASSWORD
我所做的： -禁用了我们的监视代理（认为该代理正在不使用SSL进行轮询）-->无任何内容
-添加另一个纯文本为127.0.0.1-->的localhost侦听器遇到大量问题，错误为“没有与主题XY匹配的前导”

所以，我不知道如何继续下去——也许有人有了主意

非常感谢

您的AdminClientConfig指定了
security.protocol=PLAINTEXT
——考虑到您想要启用SSL，这似乎不正确。显示该变量的可能选项

您还有
sasl.jaas.config=null
，我认为这也不正确

提供有关如何使用Kafka设置安全性的详细介绍

编辑以添加（作为对后续问题的响应）：AdminClient是一个Java类，它是从connect-distributed.properties文件实例化的。在搜索AdminClient的服务日志文件时，您将看到如下内容：

请注意，
sasl.jaas.config=[hidden]
——这是因为访问集群的用户名和密码直接存储在属性文件中，如下所示：

sasl.jaas.config=org.apache.kafka.common.security.plain.PlainLoginModule required username=\"someUsernameThisIs\" password=\"notMyRealPassword\";
请注意，双引号的转义对于配置解析器是必要的。

谢谢您的评论。我知道，adminclient设置是错误的。在这一点上，我并不真正理解卡夫卡。AdminClient是java类吗？所以有人用了错误的设置。我不知道它是什么。AdminClient确实是一个Java类，它是从您的connect-distributed.properties文件创建的-查看上次重新启动connect服务时的/var/log/kafka/connect.log。
