我有一個客戶端/服務器軟件在本地工作完美,但我不明白爲什麼,當我在遠程aws ec2實例上設置服務器時,它不起作用。當客戶端試圖連接我得到了以下錯誤:akka aws ec2連接被拒絕
[08/03/2016 12:47:36.231] [ClientSystem1213-akka.remote.default-remote-dispatcher-6] [akka.tcp://[email protected]:2555/system/endpointManager/reliableEndpointWriter-akka.tcp%3A%2F%2FSolarServerSystem%4052.59.106.25%3A2552-0/endpointWriter] AssociationError [akka.tcp://[email protected]:2555] -> [akka.tcp://[email protected]:2552]: Error [Association failed with [akka.tcp://[email protected]:2552]] [
akka.remote.EndpointAssociationException: Association failed with [akka.tcp://[email protected]:2552]
Caused by: akka.remote.transport.netty.NettyTransportExceptionNoStack: Connection refused: /52.59.106.25:2552
]
在服務器上運行netstat的-tnlp給出如下:
Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name
tcp 0 0 ::ffff:127.0.0.1:2552 :::* LISTEN 4516/java
在AWS EC2安全組入站和出站開放所有TRAFIC (所有協議 - 所有端口)。
常見到客戶端和服務器的阿卡CONF是
akka {
actor {
provider = "akka.remote.RemoteActorRefProvider"
}
remote {
enabled-transports = ["akka.remote.netty.tcp"]
netty.tcp {
hostname = "127.0.0.1"
send-buffer-size = 5000000b
receive-buffer-size = 5000000b
maximum-frame-size = 2500000b
}
watch-failure-detector {
threshold = 100
acceptable-heartbeat-pause = 20 s
}
transport-failure-detector {
heartbeat-interval = 4 s
acceptable-heartbeat-pause = 20 s
}
}
}
(I複製粘貼德故障和緩衝來自Amazon AWS EC2 ports: connection refused一部分)
服務器只通過conf的部分是:
include "common"
akka {
remote.netty.tcp.port = 2552
}
客戶端部分是:
include "common"
include "javafx-swing-dispatch"
akka {
remote.netty.tcp.port = 2555
remote {
log-config-on-start = on
log-sent-messages = on
log-received-messages = on
}
}
JavaFX的搖擺dispatch.conf感:
javafx-dispatcher {
type = "Dispatcher"
executor = "akka.dispatch.gui.JavaFXEventThreadExecutorServiceConfigurator"
throughput = 1
}
swing-dispatcher {
type = "Dispatcher"
executor = "akka.dispatch.gui.SwingEventThreadExecutorServiceConfigurator"
throughput = 1
}

那裏的問題來自任何線索?
在AWS EC2安全組入站和出站是開放的所有TRAFIC(所有協議 - 所有端口)。 – lorilan
運行akka系統的ec2實例是否在vpc中? –
它有一個vpc ID,所以我想是 – lorilan
