当LEADER_NOT_AVAILABLE错误抛出时，只需重新启动kafka代理:

/bin/kafka-server-stop.sh

紧随其后的是

/bin/kafka-server-start.sh config/server.properties

(注意:Zookeeper必须在这个时候运行，否则它不会工作)

For all those struggling with the Kafka ssl setup and seeing this LEADER_NOT_AVAILABLE error. One of the reasons that might be broken is the keystore and truststore. In the keystore you need to have private key of the server + signed server certificate. In the client truststore, you need to have intermedidate CA certificate so that client can authenticate the kafka server. If you will use ssl for interbroker communication, you need this truststore also set in the server.properties of the brokers so they can authenticate each other.

我错误地漏掉了最后一篇文章，这让我痛苦地花了很多时间去寻找这个LEADER_NOT_AVAILABLE错误可能意味着什么。希望这能帮助到一些人。

试试这个监听器=PLAINTEXT://localhost:9092 一定很有帮助

非常感谢

在服务器上添加侦听器设置后，问题得到解决。属性文件位于配置目录。 listener =PLAINTEXT://localhost(或您的服务器):9092 修改完成后重新启动kafka。使用版本2.11

如果你在本地机器上运行kafka，尝试更新$KAFKA_DIR/config/server。以下行包含的属性: //localhost:9092然后重启kafka。

我解决这个问题的方法是这样设置监听器:

advertised.listeners = PLAINTEXT://my.public.ip:9092
listeners = PLAINTEXT://0.0.0.0:9092

这使得KAFKA代理侦听所有接口。
