我尝试使用Akka.NET创建应用程序。
主要目标是使服务器可以同时处理许多客户端连接和请求。我为此选择了Akka.NET。我有一个群集,该群集现在仅包含1个节点。
我也有同时开始连接到服务器的群集客户端(ClusterClient)。客户端的逻辑很简单:它连接到服务器并在其中订阅角色。发布仍然没有问题,当然,只要连接稳定,客户就能获得一切。在〜4000-5000个客户端连接附近的某个地方,重新连接开始,并且连接因此丢失。我尝试将第二个节点添加到群集,并为每个节点建立3000个连接,但这没有成功。
问题是如何在AKKA.Net上建立服务器,该服务器将拥有大量连接(例如100 000-1 000 000)。我可以为此目的使用群集吗?
服务器

var publisher = system.ActorOf(Props.Create(() => new Publisher()), "Publisher");
var clientSub = system.ActorOf(Props.Create(() => new ClientSubscriber()), "Sub");
ClusterClientReceptionist.Get(system).RegisterService(clientSub);
if (Console.ReadLine() == "start")
{
publisher.Tell("test");
Thread.Sleep(10);
}
Console.ReadKey();
}
}
}
ClientSubscriber和发布者
class ClientSubscriber : ReceiveActor
{
public ClientSubscriber()
{
var mediator = DistributedPubSub.Get(Context.System).Mediator;
Receive<IActorRef>(senderToSub =>
{
mediator.Tell(new Subscribe("content", senderToSub));
});
}
}
public class Publisher : ReceiveActor
{
public Publisher()
{
var mediator = DistributedPubSub.Get(Context.System).Mediator;
Receive<string>(str =>
{
var upperCase = str.ToUpper();
mediator.Tell(new Publish("content", upperCase));
});
}
}
客户
static void Main(string[] args)
{
var config = ConfigurationFactory.ParseString(ConfigurationManager.AppSettings["ClientConf"]);
ActorSystem Sys = ActorSystem.Create("ClusterClient", config);
//Connection path to Cluster Node
var initialContacts = new List<ActorPath>(){
ActorPath.Parse("akka.tcp://ClusterSystem@localhost:5001/system/receptionist"),
}.ToImmutableHashSet();
var settings = ClusterClientSettings.Create(Sys).WithInitialContacts(initialContacts);
for(int i = 0; i < 5000; i++)
{
IActorRef c = Sys.ActorOf(ClusterClient.Props(settings), "client" + Path.GetFileNameWithoutExtension(Path.GetRandomFileName()));
var asd = Sys.ActorOf(Props.Create<Subscriber>(), "clientSub" + Path.GetFileNameWithoutExtension(Path.GetRandomFileName()));
c.Tell(new ClusterClient.Send("/user/Sub5001", asd));
Thread.Sleep(1/10);
}
Console.ReadKey();
}
