卡夫卡主题_授权_失败

我实际上正在努力使用 SASL 纯文本设置简单的 Kafka 身份验证并添加 ACL 授权。但当我尝试使用数据时遇到问题。

接下来，你可以看到我的配置文件。

kafka_server_jaas.conf

KafkaServer {
  org.apache.kafka.common.security.plain.PlainLoginModule required
  username="admin"
  password="admin-secret"
  user_admin="admin-secret"
  user_alice="alice-secret";
};

KafkaClient {
  org.apache.kafka.common.security.plain.PlainLoginModule required
  username="alice"
  password="alice-secret";
};

环境变量：

export KAFKA_OPTS="-Djava.security.auth.login.config=/home/user/kafka_2.10-0.10.0.1/kafka_server_jaas.conf"

Commands

Set ACL:

bin/kafka-acls.sh --authorizer kafka.security.auth.SimpleAclAuthorizer --authorizer-properties zookeeper.connect=localhost:2181 --add --allow-principal User:alice --operation All --group test-consumer-group --topic test-topic

启动卡夫卡服务器：

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

启动制作人：

bin/kafka-console-producer.sh --broker-list localhost:9092 --topic test-topic --producer.config=config/producer.properties

启动消费者：

bin/kafka-console-consumer.sh --new-consumer --zookeeper localhost:2181 --topic test-topic --from-beginning --consumer.config=config/consumer.properties  --bootstrap-server=localhost:9092

当我尝试启动消费者时，我遇到了上述问题。另外，在卡夫卡日志中，我有这个：

[2016-10-22 20:17:14,091] ERROR [KafkaApi-0] Error when handling request {group_id=test-consumer-group} (kafka.server.KafkaApis)

    at java.lang.Thread.run(Thread.java:745)

我怎样才能解决这个问题？

通过分离 jaas 客户端和 jaas 服务器解决了问题。

kafka_server_jaas.conf

KafkaServer {
  org.apache.kafka.common.security.plain.PlainLoginModule required
  username="admin"
  password="admin-secret"
  user_admin="admin-secret"
  user_alice="alice-secret";
};

kafka_client_jaas.conf

KafkaClient {
  org.apache.kafka.common.security.plain.PlainLoginModule required
  username="alice"
  password="alice-secret";
};

在同一终端上，导出 jaas 服务器conf文件并启动kafka代理：

$ export KAFKA_OPTS="-Djava.security.auth.login.config=/home/user/kafka_2.10-0.10.0.1/kafka_server_jaas.conf"
$ ./bin/kafka-server-start.sh config/server.properties

在客户端上，导出客户端 jaas conf 文件并启动消费者：

$ export KAFKA_OPTS="-Djava.security.auth.login.config=/home/user/kafka_2.10-0.10.0.1/kafka_client_jaas.conf"
$ ./bin/kafka-console-consumer.sh --new-consumer --zookeeper localhost:2181 --topic test-topic --from-beginning --consumer.config=config/consumer.properties  --bootstrap-server=localhost:9092

如果您还想生成，请在另一个终端窗口上执行此操作：

$ export KAFKA_OPTS="-Djava.security.auth.login.config=/home/user/kafka_2.10-0.10.0.1/kafka_client_jaas.conf"
$ ./bin/kafka-console-producer.sh --broker-list localhost:9092 --topic test-topic --producer.config=config/producer.properties
