apache-kafka - 配置 Kafka 客户端以连接已发布的 SSL key /证书

Question

我正在使用运行 0.10.1.1 并使用 SSL 的 Heroku Kafka。它们只支持最新的协议(protocol)。

Heroku Kafka 使用 SSL 进行身份验证和颁发客户端证书和 key ，并提供 CA 证书。我将它们分别放在 client_cert.pem、client_key.pem 和 trusted_cert.pem 中，然后运行以下命令来构建 keystore :

openssl pkcs12 -export -in client_cert.pem -inkey client_key.pem -certfile client_cert.pem -out client.p12
keytool -importkeystore -srckeystore client.p12 -srcstoretype pkcs12 -destkeystore kafka.keystore.jks -deststoretype JKS
keytool -keystore kafka.truststore.jks -alias CARoot -import -file trusted_cert.pem

然后我创建了包含以下内容的 client-ssl.properties:

ssl.protocol=SSL
security.protocol=SSL
ssl.truststore.location=kafka.truststore.jks
ssl.truststore.type=JKS
ssl.truststore.password=xxxx
ssl.keystore.location=kafka.keystore.jks
ssl.keystore.type=JKS
ssl.keystore.password=xxxx
ssl.key.password=xxxx

然后我将 kafka-console-producer(版本 0.10.1.1)与以下内容一起使用:

kafka-console-producer --broker-list kafka+ssl://a.a.a.a:9096,kafka+ssl://b.b.b.b:9096,kafka+ssl://c.c.c.c:9096 --producer.config client-ssl.properties --topic robintest

(robintest 主题已创建。)

这些条目会一直持续到我终止进程为止。

我已经尝试了每一种配置组合，包括在属性文件中为所有配置添加前缀 producer.，删除整个配置(这似乎没有什么区别)，将密码设置为不正确值(这似乎没有什么区别)。我还尝试使用他们的凭据连接到不同的提供商 (www.cloudkarafka.com)，我得到了相同的结果。所以这绝对像是一个配置问题。

事实证明，我的 Kafka 集群(Heroku 附加组件)实际上并没有运行 0.10.1.1，它运行的是 0.10.0.1。两者似乎具有不兼容的消费者 API。 (我不得不说，“这正是存在语义版本控制的原因。”)

收件人upgrade Kafka running on Heroku ，使用:heroku kafka:upgrade --version 0.10 升级到最新的 0.10.X 版本。因此，如果您使用的是 0.9 并且想要 0.10.0.1，祝您好运。
