Question

我按照here和here的说明向我的Confluent-3.0.1 Kafka群集添加了SSL安全性。

在下面的Linux事务片段中，我已经用myserverA，myserverB和myserverC替换了我的服务器名称。我也模糊了密码。这是我在留言板上的第一篇帖子。对于这篇文章中任何格式不正确的部分，我深表歉意。

我的问题：

什么ACL控制对下面显示的提取偏移的访问？我是否需要更改配置或SSL密钥？

非常感谢您提供的任何帮助。

我能够通过SSL使用kafka-console-producer生成数据，但无法使用kafka-console-consumer读取数据。我收到以下错误：

[kafka@myserverA confluent-3.0.1]$ /kafka/confluent-3.0.1/bin/kafka-console-consumer --bootstrap-server myserverA:9093 --zookeeper myserverA:2181/kafka --topic ssl-test --from-beginning --new-consumer --consumer.config /kafka/data/client/ssl/client.properties
[2017-06-27 13:11:50,462] WARN Attempt to fetch offsets for partition ssl-test-0 failed due to: Not authorized to access topics: [Topic authorization failed.] (org.apache.kafka.clients.consumer.internals.Fetcher)

org.apache.kafka.common.errors.TopicAuthorizationException: Not authorized to access topics: [ssl-test]

目前尚不清楚我的问题是在客户端配置还是代理间配置中。

我的三个代理中的每个代理上的server.properties文件包括以下内容：

###################### SSL Configuration ################
#
ssl.keystore.location=/kafka/data/ssl/keystore/kafka.keystore.jks
ssl.keystore.password=<hidden for this posting>

#ssl.cipher.suites=
ssl.enabled.protocols = TLSv1.2,TLSv1.1,TLSv1

security.inter.broker.protocol=ssl

我对producer.config和consumer.config使用相同的client.properties。它包含以下内容：

###################### SSL Configuration ################
#
security.protocol=ssl

ssl.keystore.location=/kafka/data/client/ssl/keystore/kafka.client.keystore.jks

ssl.truststore.type = JKS

我在ssl-test主题上有大量的ACL授权。我尝试过：1）逗号后带空格的SSL编号，2）逗号后没有空格的SSL编号，3）代理证书的SSL通用名称

[root@myserverA ~]# /kafka/confluent-3.0.1/bin/kafka-acls --authorizer-properties zookeeper.connect=myserverA:2181/kafka --list --topic ssl-test

kafka-console-producer通常通过SSL运行：

[kafka@myserverA confluent-3.0.1]$ bin/kafka-console-producer --broker-list myserverA:9093 --topic ssl-test --producer.config /kafka/data/client/ssl/client.properties
j
k

Answer 1

根据the documentation，消费者需要有关主题的READ 和 DESCRIBE，以及需要READ的消费者群体。选项--consumer可以用作方便将所有这些设置为一次;使用他们的例子：

bin/kafka-acls.sh --authorizer-properties zookeeper.connect=localhost:2181 \
  --add \
  --allow-principal User:Bob \
  --consumer \
  --topic Test-topic \
  --group Group-1

Answer 2

我的Kafka SSL配置存在多个问题。但是，显式错误＆＃34; WARN尝试获取分区ssl-test-0的偏移失败...＆＃34;运行kafka-console-consumer时，由于客户端证书未包含在kafka节点B和C的信任库中。

为kafka-console-consumer配置SSL和ACL
