如果我想让两个 Lighthouse 种子节点在不同的 PC 上运行，每个节点都应该知道另一个节点，我应该如何配置它们？尽管我发现提到使用多个 Lighthouse 实例并看到使用多个种子节点的非种子节点配置，但我无法在知道一个的不同 PC 上找到多个种子节点（特别是 Lighthouse）的示例其他。

我目前有这样的东西，但我不确定它是否正确。

                                port = 4053

                        loggers = ["Akka.Logger.NLog.NLogLogger,Akka.Logger.NLog"]

                            seed-nodes = [

                            roles = [lighthouse]
                        }

与其他实例的配置基本相同，但有以下区别：

akka.remote：

public-hostname = "192.168.72.56"

akka.cluster：

    seed-nodes = [
  "akka.tcp://MySystem@192.168.72.56:4053"
  "akka.tcp://MySystem@192.168.72.55:4053"
] #manually populate other seed nodes here, i.e. "akka.tcp://lighthouse@127.0.0.1:4053", "akka.tcp://lighthouse@127.0.0.1:4044"

这是正确的吗？有什么我应该改变或可以改进的吗？确保一切正常运行的最佳方法是什么？我是否应该删除每个配置中的第一个种子节点，因为评论似乎表明不需要包含它？

如果我在 192.168.72.55 上启动节点，然后在 192.168.72.56 上启动节点，我会看到它在 192.168.72.55 上加入并在 192.168.72.56 上收到欢迎消息。如果我关闭 192.168.72.56 实例并重新启动它，它再次受到欢迎，但 192.168.72.55 实例不断输出消息，例如：

也许您应该使用 BroadcastRouter 来聚合每个节点。比每个节点都应该告诉这个路由器“我是”这样的想法。

实际上，每个 BroadcastRouter 的孩子都应该收到带有 Sender 属性的“我是”。

这样，您应该使用此构造函数： https ://github.com/akkadotnet/akka.net/blob/master/src/core/Akka/Routing/Broadcast.cs#L266
