Question

我已经在Cloudera中运行了3个经纪人kerberised Kafka 0.10安装，并且我尝试使用SASL / PLAIN进行身份验证

我将kafka_server_jaas.conf传递给每个经纪人的JVM。

KafkaServer { org.apache.kafka.common.security.plain.PlainLoginModule required username=admin password=password1 user_admin=password1 user_remote=password1; };

我的server.properties（或Cloudera重命名的kafka.properties）设置如下;

listeners=SASL_SSL://10.10.3.47:9093 # ip set for each broker advertised.listeners=SASL_SSL://10.10.3.47:9093 # ip set for each broker sasl.enabled.mechanisms=GSSAPI,PLAIN security.inter.broker.protocol=SASL_SSL sasl.mechanism.inter.broker.protocol=GSSAPI

当Kafka启动时，代理间通信一切正常，但是当我尝试使用控制台生产者进行连接时，我发现Timeout无法更新元数据

bin/kafka-consolproducer --broker-list 10.10.3.161:9093 --topic test1 --producer.config client.properties.plain

client.properties.plain设置为

security.protocol=SASL_SSL sasl.mechanism=PLAIN

最后，客户端jaas.conf

KafkaClient { org.apache.kafka.common.security.plain.PlainLoginModule required username="remote" password="password1"; };

据我所知，我已经正确地遵循了所有指示，任何人都可以看错了吗？

更新我已经将控制台消费者的日志记录提高了一点，我收到了以下错误;

我在SASL_PLAINTEXT身份验证中遇到了类似的问题。我能够连接到代理（通过kafka-python），但是我从生产者发送的任何消息都会超时。

我最后宣传了SASL_PLAINTEXT和PLAINTEXT监听器，但只是通过AWS安全组公开了SASL_PLAINTEXT监听器。

我的server_jaas.conf基本相同。

我的server.properties使用了以下设置：

security.inter.broker.protocol=PLAINTEXT
sasl.mechanism.inter.broker.protocol=PLAIN
sasl.enabled.mechanisms=PLAIN
advertised.listeners=SASL_PLAINTEXT://example.com:9095,PLAINTEXT://example.com:9092
listeners = SASL_PLAINTEXT://0.0.0.0:9095,PLAINTEXT://0.0.0.0:9092

我用kafka-python客户端调试它，我的命令看起来像这样（python）

from kafka import KafkaProducer
producer = KafkaProducer(bootstrap_servers='example.com:9095', security_protocol="SASL_PLAINTEXT", sasl_mechanism='PLAIN', sasl_plain_username='username', sasl_plain_password='password')

通过此设置，我可以进行用户名/密码身份验证，还可以在没有超时的情况下向代理生成和使用消息。

希望这在某种程度上有所帮助：）
