我已经使用 docker 建立了一个基本的 Zookeeper 和 kafka 版本 5.4.0 的三服务器集群。对于 zookeeper 和 kafka,我已经指定了所有三个引导服务器。我正在尝试以允许一台服务器关闭并且集群仍将正常运行的方式进行设置。我正在尝试让控制中心正常工作,但遇到了问题。首先,似乎只有一个服务器能够成功运行控制中心,并且只有当我指定它正在运行的引导服务器时,而不是所有三个服务器。如果我尝试在其他两台服务器上启动控制中心,它们将无法启动,并且会不断记录以下内容:
INFO unable to get command store (io.confluent.command.CommandStore)
我不确定如何最好地完成这项工作。因为它可能会有所帮助,所以我在我的 docker-compose 文件下方发布了 zookeeper/broker 对以及控制中心的文件。如果我有任何错误指定或您认为需要更改,请告诉我。
zookeeper/kafka 代理 docker-compose.yml (其他仅通过广告侦听器 IP 不同):
