ssl - 为 kafka-console-consumer 配置 SSL 和 ACL

Question

我正在按照说明 here 向我的 Confluent-3.0.1 Kafka 集群添加 SSL 安全性和 here .

在下面的 Linux 交易片段中，我用 myserverA、myserverB 和 myserverC 替换了我的服务器名称。我还隐藏了密码。这是我第一次在留言板上发帖。对于这篇文章中格式不正确的部分，我深表歉意。

我的问题:

什么 ACL 控制下面显示的获取偏移量的访问权限？我需要更改我的配置或 SSL key 吗？

非常感谢您提供的任何帮助。

我能够使用 kafka-console-producer 通过 SSL 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

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

不清楚我的问题是出在客户端配置上，还是中间件配置上。

我的三个代理的 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

我有大量关于 ssl-test 主题的 ACL 授权。我试过:1)逗号后带空格的 SSL 域名，2)逗号后没有空格的 SSL 域名，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 通过 SSL 正常运行:

[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

根据 the documentation消费者需要阅读和关于主题的描述，以及需要阅读的消费者群体。选项 --consumer 可以用来方便地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
