Now when the cluster is enabled and configured, a JVM needs to join the cluster in order to form one. For that Akka Cluster requires an initial set of JVMs which can be contacted by a new JVM to join the cluster. They are known asSeed Nodes. Although seed nodes are not special nodes...

Cluster subscriptions can be used to receive messages when cluster state changes. For example, registering for all MemberEvents, then using the manager to have a node leave the cluster will result in events for the node going through the Membership Lifecycle. 群集订阅可用于在群集状态更改时接收消息。
可以通过Cluster(system).subscribe 方法订阅cluster成员变化通知 cluster.subscribe(self,classOf[MemberEvent],classOf[UnreachableMember])cluster.subscribe(self,initialStateMode=InitialStateAsEvents,classOf[MemberEvent],classOf[UnreachableMember]) Cluster成员生命周期事件 ClusterEvent.MemberJoinedClusterEvent.MemberUp...
以这种方式使用ClusterClient实际上没有意义，并且与使用分布式发布sub没有任何关系，因为您的两个节点都是...
