c - librdkafka 消费者和 ssl 配置

Question

我使用 librdkafka 作为客户端消费者，我已经配置代理和客户端以支持 SSL，对于代理:

listeners = PLAINTEXT://172.20.54.9:9092,SSL://172.20.54.9:9093
ssl.keystore.location=E:/project_files/Project/kafka_2.11-2.1.0/config/kafka.server.keystore.jks
ssl.keystore.password=ismail
ssl.key.password=ismail
ssl.truststore.location=E:/project_files/Project/kafka_2.11-2.1.0/config/kafka.server.truststore.jks
ssl.truststore.password=password

在客户端我使用这个配置:

rd_kafka_conf_set(conf, "metadata.broker.list", "172.20.54.9:9093",
                      NULL, 0);
rd_kafka_conf_set(conf, "security.protocol", "ssl",
                      NULL, 0);
rd_kafka_conf_set(conf, "ssl.ca.location", "/usr/bin/NetSens/CARoot.pem",
                      NULL, 0);
rd_kafka_conf_set(conf, "ssl.certificate.location", "/usr/bin/NetSens/certificate.pem",
                      NULL, 0);
rd_kafka_conf_set(conf, "ssl.key.location", "/usr/bin/NetSens/key.pem",
                      NULL, 0);
rd_kafka_conf_set(conf, "ssl.key.password", "password",
                      NULL, 0);

我收到了这个错误:

1559309856.897 RDKAFKA-3-ERROR: rdkafka#consumer-1: [thrd:ssl://172.20.54.9:9093/bootstrap]: ssl://172.20.54.9:9093/bootstrap: SSL handshake failed: ../ssl/record/ssl3_record.c:252: error:1408F10B:SSL routines:ssl3_get_record:wrong version number:  (after 7ms in state CONNECT)

有关更多信息，我同时拥有另一个使用相同证书和 key 的 python kafka 客户端，它工作正常。如果有任何帮助，我将不胜感激。

我相信您的问题与 this issue 有关.

您可以通过在调用 keytool -genkey 生成证书时包含 -keyalg RSA 来修复它。
