me="clusterSystem",config=config) val eventListener = clusterSystem.actorOf(Props[EventLisener],"eventListener") val cluster = Cluster(clusterSystem) cluster.registerOnMemberRemoved(println("Leaving cluster. I should cleanup... ")) cluster.registerOnMemberUp(println("Hookup to cluster. Do some setups ...")) println("actor system started!") scala.io.StdIn.readLine() clusterSystem.terminate() } }

我们在多个terminal上用sbt来测试运行：

1、run "2551" "2551" //这是个seed-node

2、run "0" "2551" //port=0代表由系统自动选择端口
