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，在启动服务时遇到错误。代理程序似乎启动正确（似乎发生了领导人选举等），但一旦开始执行任何集群操作，我就会在日志中不断看到下面的错误。

    [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

尝试重新创建密钥和信任存储，尝试从代理间侦听器中删除SSL（这会导致匿名主体，我不想授予对任何资源的访问权）。

要解释我的配置：

• 使用SSL principal builder运行Kafka 2.2
• 我设置了三个侦听器——一个在公共接口上，两个在私有接口上（一个用于代理间通信，一个用于内部用户）
• 在所有3个侦听器上启用SSL
• 每个侦听器都绑定到自己的密钥和信任存储（因为我需要能够为内部地址提供不同的证书，并且能够信任不同的签名CA），并且为每个密钥/密钥库提供SSL密钥密码
• 证书使用本地生成的密钥创建，本地CSR生成，然后由运行在CFSSL multiroot上的CA签名
• 然后使用密钥（相同密码）、签名证书和导入的CA证书创建密钥库
• 创建了信任库，并在此处添加了证书颁发CA

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