我在初始化远程 IP 地址上的参与者系统时遇到了麻烦。我正在使用 akka 演员和戏剧！框架。代码和远程参与者系统都在远程机架空间服务器上。当我尝试在另一台服务器上创建远程参与者系统时，它无法绑定到该 IP 地址。我认为这不是网络或防火墙问题，因为 Rackspace 说他们打开了服务器之间的所有连接。这是我收到的错误消息：

我在这里创建远程演员系统：

object Payment extends Controller {
  var goodies: AuthNetActorObject = null

  val system = ActorSystem("RemoteCreation", ConfigFactory.load.getConfig("remotecreation"))
  val myActor = system.actorOf(Props[authNetActor.AuthNetActorMain], name = "remoteActor")
  ...
}

这是我在 Application.conf 文件中定义远程创建的地方：

remotecreation{ #user defined name for the configuration
    include "common"
    akka {
            actor{
                    #serializer{
                    #       proto = "akka.serialization.ProtobufSerializer"
                    #       daemon-create = "akka.serialization.DaemonMsgCreateSerializer"
                    #}

                    #serialization-bindings{
                    #       "com.google.protobuf.GeneratedMessage" = proto
                    #       "akka.remote.DaemonMsgCreate" = daemon-create
                    #}

                    deployment{
                            /remoteActor{   #Specifically has to be the name of the remote actor
                                    remote="akka://RemoteCreation@172.17.100.232:2554"
                            #       router = "round-robin"
                            #       nr-of-instances = 10
                            #       target {
                            #               nodes = ["akka://RemoteCreation@172.17.100.232:2554", "akka://RemoteCreation@172.17.100.224:2554"]
                            #       }
                            }
                    }
            }
    }
}

这是我在定义中包含的 common.conf 文件：

akka {

  actor {
    provider = "akka.remote.RemoteActorRefProvider"
  }

  remote {
        transport = "akka.remote.netty.NettyRemoteTransport"
        log-received-messages = on
        log-sent-messages = on
        log-remote-lifecycle-events = on

    netty {
      hostname = "172.17.100.232"       #Broadcast IP address of remote system
      port = 2554
        log-received-messages = on
        log-sent-messages = on
          log-remote-lifecycle-events = on

    }
  }
}

这可能意味着其他东西正在使用该机器上的该端口。登录到该机器并netstat -anp | grep 2554以 root 身份运行，然后查看该端口是否处于LISTEN状态。如果是这样，进程 ID 将位于最后一列。
