在JAAS或KAFKA CONFIG(不是Kerberos)中均未定义ServiceName

Question

我正在尝试配置kafka客户端以对安全的kafkaserver进行身份验证。我已经设置了JAAS和SSL配置，但是它抱怨ServiceNames。

我不使用kerberos。

命令

KAFKA_OPTS="-Djava.security.auth.login.config=./jaas.conf"  
kafka-console-producer --broker-list k0:9092,k1:9092,k2:9092 
   --topic test-topic 
   --producer.config ./ssl.properties

错误

org.apache.kafka.common.KafkaException: Failed to construct kafka producer
    at org.apache.kafka.clients.producer.KafkaProducer.<init>
    [ ... ] 
Caused by: java.lang.IllegalArgumentException: No serviceName defined in either JAAS or Kafka config

jaas.conf

KafkaServer {
    org.apache.kafka.common.security.plain.PlainLoginModule required
    serviceName="kafka"
    password="broker-secret"
    user_broker="broker-secret"
    sasl.enabled.mechanisms=PLAIN
    sasl.mechanism.inter.broker.protocol=PLAIN
    confluent.metrics.reporter.sasl.mechanism=PLAIN
    user_username1="password1";
};

ssl.properties

bootstrap.servers=k0:9092,k1:9092,k2:9092
security.protocol=SASL_PLAINTEXT
ssl.truststore.location=/var/ssl/private/client.truststore.jks

Answer 1

此错误表明您的kafka生产者看不到JAAS配置。要解决此问题，您要么需要包括

sasl.jaas.config=org.apache.kafka.common.security.plain.PlainLoginModule required username="(username)" password="(password)";

在您的ssl.properties文件中，或将其导出在您的路径

中

export KAFKA_OPTS="-Djava.security.auth.login.config=path/to/jaas.conf"

Answer 2

当我本地运行kafka使用生产config

时也会遇到此错误

security.protocol=SASL_PLAINTEXT

删除SASL Part

后，我再次工作了

security.protocol=PLAINTEXT
