Я испытываю функцию akka remote для инструмента, который я создаю. Фактически, я смог сделать основные и удаленные системы работать на одном хосте с разными портами. Обратите внимание, что мои удаленные серверы работают через маршрутизатор, как описано в документах akka.Akka удаленные маршруты проблема с именем хоста
Теперь я пытаюсь использовать несколько лазурных виртуальных машин, чтобы сделать лучший эксперимент, но у меня возникают некоторые проблемы.
Приложение ядро имеет следующую конфигурацию (я изменил имена некоторых из соображений безопасности):
akka.actor.deployment {
/querierActor/querierPool {
router = round-robin-pool
nr-of-instances = 12
target.nodes = [
"akka.tcp://[email protected]:2560"
,"akka.tcp://[email protected]:2560"
,"akka.tcp://[email protected]:2560"
]
}
}
// remote configuration. Use it for multiple machines calculation
akka {
actor {
provider = "akka.remote.RemoteActorRefProvider"
}
remote {
enabled-transports = ["akka.remote.netty.tcp"]
netty.tcp {
maximum-frame-size = 100MiB
port = 2552
hostname = "0.0.0.0"
}
}
}
Хотя удаленных хостов имеет следующую конфигурацию:
akka.actor.deployment {
/querierActor/querierPool {
router = balancing-pool
nr-of-instances = 15
}
}
akka {
actor {
provider = "akka.remote.RemoteActorRefProvider"
}
remote {
enabled-transports = ["akka.remote.netty.tcp"]
netty.tcp {
maximum-frame-size = 100MiB
hostname = "0.0.0.0"
port = 2560
}
}
}
Используя эту конфигурацию, сервер и удаленные хосты, по-видимому, могут общаться, но удаленный хост начинает регистрировать некоторые ошибки:
[ERROR] [01/17/2015 12:55:05.734] [SYSTEM-akka.remote.default-remote-dispatcher-16] [akka.tcp://[email protected]:2560/system/endpointManager/reliableEndpointWriter-akka.tcp%3A%2F%2FSYSTEM%400.0.0.0%3A2552-0/endpointWriter] dropping message [class akka.actor.ActorSelectionMessage] for non-local recipient [Actor[akka.tcp://[email protected]:2560/]] arriving at [akka.tcp://[email protected]:2560] inbound addresses are [akka.tcp://[email protected]:2560]
И после этого сервер и удаленный хост начинает регистрировать ошибку и блокировать. Ошибка

я понял, что проблема может быть в конфигурации хоста и попытался поставить имя хоста на сервер и удаленный хост. Но в этом случае система даже не загружается:

Я не знаю, что я делаю неправильно. Я попытался найти информацию о проблеме, но все, что я нашел, связано с моей проблемой. Я также открыл порты в лазурной конфигурации.
Как я могу позволить хосту моего сервера правильно общаться с удаленными хостами?
