Question

我正在尝试使用此文档在Win 7计算机上创建基本的akka群集：
http://doc.akka.io/docs/akka/snapshot/scala/cluster-usage.html

我在运行种子节点时遇到错误（下面有更多内容）

AdriansClusterSystem-akka.actor.default-dispa tcher-16] [阿卡：// AdriansClusterSystem /系统/ endpointManager / reliableEndpointWr ITER-akka.tcp％3A％2F％2FAdriansClusterSystem％40127.0.0.1％3A2552-3 / endpointWriter] 为非本地删除消息[class akka.actor.SelectChildName] 收件人[法案或[akka.tcp：//ClusterSystem@127.0.0.1：2552 /]]到达在[akka.tcp：// ClusterSys tem@127.0.0.1:2552]入站地址是 [akka.tcp：//AdriansClusterSystem@127.0 .0.1：2552]

问题： 为什么我收到此错误？我是否遗漏了akka文档中的内容？

我的.conf文件：
我将这个额外的行*添加到上面的URL列出的文件中* enabled-transports = ["akka.remote.netty.tcp"]

akka {
  actor {
    provider = "akka.cluster.ClusterActorRefProvider"
  }
  remote {
    enabled-transports = ["akka.remote.netty.tcp"]  <--added this from remoting
    log-remote-lifecycle-events = off
    netty.tcp {
      hostname = "127.0.0.1"
      port = 0
    }
  }
  cluster {
    seed-nodes = [
    "akka.tcp://ClusterSystem@127.0.0.1:2551",
    "akka.tcp://ClusterSystem@127.0.0.1:2552"]

  auto-down = on
  }
}

我启动了两个节点，每个节点都在不同的sbt窗口

run-main sample.cluster.simple.SimpleClusterApp 2551  
run-main sample.cluster.simple.SimpleClusterApp 2552

这两个启动都很好，然后反复显示ERROR消息：

如果我现在

run-main sample.cluster.simple.SimpleClusterApp

应该选择一个随机端口并运行一个种子节点，它就像其他2个种子节点一样开始，然后将一个未找到的类异常显示为INFO而没有当前成员

是的，它只是挂在那里，我必须关闭sbt窗口才能终止它。

Answer 1

看起来您的种子节点使用ClusterSystem作为actor系统名称，但根据您的日志，您使用AdriansClusterSystem作为actor系统名称。尝试将种子节点更改为：

seed-nodes = [
"akka.tcp://AdriansClusterSystem@127.0.0.1:2551",
"akka.tcp://AdriansClusterSystem@127.0.0.1:2552"]

akka群集种子节点给出错误：为非本地收件人丢弃消息
