Kafka-Zookeeper-ACL配置

Question

设置

我在端口8082上有一个正在运行的服务器（wilfly swarm,keycloack authenticated）,它承载了我的日志功能。我可以通过REST将日志线推送到这个服务器。在幕后，Kafka的制作人正在运行和传播给Kafka的信息。

• 我在2181口有动物园管理员
• 我有一个代理在端口9092运行
• 日志服务器在端口8082上运行

listeners=PLAINTEXT://localhost:9092
authorizer.class.name=kafka.security.auth.SimpleAclAuthorizer
super.users=User:Bob;User:Alice;User:anonymous

call kafka\bin\windows\kafka-topics.bat --create --zookeeper localhost:2181 --replication-factor 1 --partitions 1 --topic testtopic

    @Produces
    private Producer<String, String> stringStringProducer(){
        Properties props = new Properties();
        props.put("bootstrap.servers", "localhost:9092");
        props.put("acks", "all");
        props.put("retries", 0);
        props.put("batch.size", 16384);
        props.put("linger.ms", 1);
        props.put("buffer.memory", 33554432);
        props.put("key.serializer", "org.apache.kafka.common.serialization.StringSerializer");
        props.put("value.serializer", "org.apache.kafka.common.serialization.StringSerializer");
        Producer<String, String> producer = null;
        try {
            producer = new KafkaProducer<>(props);
            return producer;
        } catch (Exception e) {
            throw new RuntimeException(e);
        }
    }

当我试图通过Java生成器（和控制台生成器）生成消息时，我得到：

[org.apache.kafka.clients.NetworkClient] (kafka-producer-network-thread | producer-6) Error while fetching metadata with correlation id 10 : {testtopic=UNKNOWN_TOPIC_OR_PARTITION}

有人知道我做错了什么吗？

第一种解决方案

call kafka\bin\windows\kafka-topics.bat --create --zookeeper localhost:2181 --replication-factor 1 --partitions 1 --topic testtopic

call kafka\bin\windows\kafka-acls.bat --add --allow-principal User:anonymous --authorizer kafka.security.auth.SimpleAclAuthorizer --authorizer-properties zookeeper.connect=localhost:2181  --allow-host http://localhost:8082 --operation Read --operation Write --topic testtopic
call kafka\bin\windows\kafka-acls.bat --add --allow-principal User:ANONYMOUS --authorizer kafka.security.auth.SimpleAclAuthorizer --authorizer-properties zookeeper.connect=localhost:2181  --allow-host 127.0.0.1 --operation Read --operation Write --topic testtopic

call kafka\bin\windows\kafka-acls.bat --authorizer kafka.security.auth.SimpleAclAuthorizer --authorizer-properties zookeeper.connect=localhost:2181 --add --allow-principal User:anonymous --consumer --topic testtopic --group group --allow-host http://localhost:8082
call kafka\bin\windows\kafka-acls.bat --authorizer kafka.security.auth.SimpleAclAuthorizer --authorizer-properties zookeeper.connect=localhost:2181 --add --allow-principal User:ANONYMOUS --consumer --topic testtopic --group group --allow-host 127.0.0.1

call kafka\bin\windows\kafka-acls.bat --authorizer kafka.security.auth.SimpleAclAuthorizer --authorizer-properties zookeeper.connect=localhost:2181 --add --allow-principal User:anonymous --producer --topic testtopic --allow-host http://localhost:8082
call kafka\bin\windows\kafka-acls.bat --authorizer kafka.security.auth.SimpleAclAuthorizer --authorizer-properties zookeeper.connect=localhost:2181 --add --allow-principal User:ANONYMOUS --producer --topic testtopic --allow-host 127.0.0.1

我在代理配置（server.properties）中为超级用户添加了“匿名”：

authorizer.class.name=kafka.security.auth.SimpleAclAuthorizer
super.users=User:Bob;User:Alice;User:ANONYMOUS
#port = 9092
#advertised.host.name = localhost
#listeners=SASL_SSL://localhost:9092
#security.inter.broker.protocol=SASL_SSL
#sasl.mechanism.inter.broker.protocol=PLAIN
#sasl.enabled.mechanisms=PLAIN
host.name=127.0.0.1
advertised.host.name=localhost
advertised.port=9092

Answer 1

出现此问题是因为您在以下行中启用了授权：

authorizer.class.name=kafka.security.auth.SimpleAclAuthorizer

但是代理是用user:anonymouth运行的，因为下面的行：

listeners=PLAINTEXT://localhost:9092

也就是说，代理没有办法对自己进行身份验证。在我的情况下（SSL身份验证），我必须执行以下操作：

null

另外，你的回答中的变通方法是不鼓励的。你可以在这里读到它的含义。
