Kafka Security 实现问题 SASL SSL 和 SCRAM

Question

我在启动 kafka 服务器时遇到错误，已经设置了 SSL 并且它对 kafka 3 代理工作正常。 而且zookeeper也设置了SSL

现在尝试从服务器属性文件为 kafka 代理设置带有 SASL_SSL 的 SCRAM。

它不起作用我使用以下命令创建了一个用户

kafka-configs.sh --zookeeper localhost:2182 --zk-tls-config-file zookeeper-client.properties --entity-type users --entity-name broker-admin --alter --add-config 'SCRAM-SHA-512=[password=DEM123]'

我可以看到用户已创建。

但是在尝试运行命令以运行 kafka 代理时

kafka-server-start.sh -daemon server-0.properties

我检查了 server.log 文件时出现了一些错误

[2021-10-05 16:21:38,369] ERROR [KafkaServer id=0] Fatal error during KafkaServer startup. Prepare to shutdown (kafka.server.KafkaServer)

org.apache.zookeeper.KeeperException$NoAuthException: KeeperErrorCode = NoAuth for /config/users/broker-admin

有人可以支持我吗？

让我分享我的 zookeeper.properpties 文件

Answer 1

您可以尝试将 'skipACL=yes' 设置为您的 zookeeper.properties 吗？ 如果您在创建“broker-admin”用户时使用 SSL 客户端证书对 Zookeeper 进行了身份验证，我认为这是因为从您执行命令的位置以外的访问被拒绝。
