ssl - 代理间通信的 Kafka SSL 身份验证问题

Question

我目前正在使用 SSL 身份验证配置 Apache Kafka，但在启动该服务时遇到错误。看起来代理正确启动(领导者选举等似乎发生)，但一旦任何集群操作开始发生，我就会在日志中不断收到以下错误。

    [2019-05-16 11:04:00,351] INFO [Controller id=1, targetBrokerId=1] Failed authentication with XXXX/YYYY (SSL handshake failed) (org.apache.kafka.common.network.Selector)
[2019-05-16 11:04:00,351] DEBUG [Controller id=1, targetBrokerId=1] Node 1 disconnected. (org.apache.kafka.clients.NetworkClient)
[2019-05-16 11:04:00,351] DEBUG An authentication error occurred in broker-to-broker communication. (org.apache.kafka.clients.ManualMetadataUpdater)
org.apache.kafka.common.errors.SslAuthenticationException: SSL handshake failed
Caused by: javax.net.ssl.SSLProtocolException: Handshake message sequence violation, 2

尝试重新创建 key 和信任存储，尝试从代理间监听器中删除 SSL(这导致我不想授予对任何资源的访问权限的匿名委托(delegate)人)。

解释我的配置:

• 使用 SSL 主体构建器运行 Kafka 2.2
• 我有 3 个监听器设置 - 一个在公共(public)接口(interface)上，两个在私有(private)接口(interface)上(一个用于经纪人间通信，一个用于内部消费者)
• 所有 3 个监听器都启用了 SSL
• 每个监听器都绑定(bind)到它自己的 key 和信任库(因为我需要能够为内部地址提供不同的证书，以及能够信任不同的签名 CA)，并且为每个监听器提供 SSL key 密码 key / keystore 。
• 证书是使用本地生成的 key 创建的，本地 CSR 生成然后由在 CFSSL 多根上运行的 CA 签名。
• 然后使用 key (相同密码)、签名证书和导入的 CA 证书创建 keystore 。
• Truststore 已创建，证书颁发 CA 已添加到此处。

Answer 1

您是否按照描述的顺序将证书插入 keystore ？首先设置 ca，然后由 ca 签名的证书以正确获取信任链可能很重要。
