过去两天我一直在努力弄清楚如何将基本控制台应用程序部署到Azure辅助工作者角色,并从某种基于客户端的应用程序远程访问它。 MVC网络应用程序。答案如下
答案 0 :(得分:3)
我开始将我的Actor状态包含在我的MVC应用程序与之通信的本地控制台应用程序中。我希望将我的应用程序部署在Azure生态系统中,并认为将状态保持在一个辅助角色中,在应用服务中托管一个思考“客户端”MVC应用程序将是最好的前进方式。
确保将您的Actor系统从解决方案中提取到其自己的项目中。在解决方案中创建一个新的Worker角色CloudService项目。
我按如下方式配置了WorkRole:
public class WorkerRole : RoleEntryPoint
{
private readonly CancellationTokenSource cancellationTokenSource = new CancellationTokenSource();
private readonly ManualResetEvent runCompleteEvent = new ManualResetEvent(false);
private static ActorSystem ActorSystemInstance;
public override void Run()
{
Trace.TraceInformation("Game.State.WorkerRole is running");
try
{
this.RunAsync(this.cancellationTokenSource.Token).Wait();
}
finally
{
this.runCompleteEvent.Set();
}
}
public override bool OnStart()
{
ActorSystemInstance = ActorSystem.Create("GameSystem");
// Set the maximum number of concurrent connections
ServicePointManager.DefaultConnectionLimit = 12;
// For information on handling configuration changes
// see the MSDN topic at https://go.microsoft.com/fwlink/?LinkId=166357.
bool result = base.OnStart();
Trace.TraceInformation("Game.State.WorkerRole has been started");
return result;
}
public override void OnStop()
{
ActorSystemInstance.Terminate();
Trace.TraceInformation("Game.State.WorkerRole is stopping");
this.cancellationTokenSource.Cancel();
this.runCompleteEvent.WaitOne();
base.OnStop();
Trace.TraceInformation("Game.State.WorkerRole has stopped");
}
private async Task RunAsync(CancellationToken cancellationToken)
{
var gameController = ActorSystemInstance.ActorOf<GameControllerActor>("GameController");
while (!cancellationToken.IsCancellationRequested)
{
Trace.TraceInformation("Working");
await Task.Delay(1000);
}
}
}
我的HOCON文件(在app.config中)如下:
<akka>
<hocon>
<![CDATA[
akka {
loglevel = DEBUG
actor {
provider = "Akka.Remote.RemoteActorRefProvider, Akka.Remote"
debug {
receive = on
autoreceive = on
lifecycle = on
event-stream = on
unhandled = on
}
}
remote {
helios.tcp {
transport-class = "Akka.Remote.Transport.Helios.HeliosTcpTransport, Akka.Remote"
transport-protocol = tcp
enforce-ip-family = true
port = xxxx //the port configured in your worker role endpoint
hostname = "0.0.0.0" //This is the local hostname of the worker role, using 0.0.0.0 will set the Remote actor to "listen" on all available DNS/IP addresses including the loopback (127.0.0.1)
pulic-hostname = "xx.xx.xx.xx" //IP Address OR DNS name, but whatever is set here is what MUST be used in the Actor Selector path on the client in order for proper "association" to occur. I did find that DNS name was required for my application as I was using SignalR as a bridge between the Actor system and the web client.
}
}
}
]]>
</hocon>
我们需要在worker角色配置中定义我们的端点,以便我们“公开”一个端口,通过该端口我们可以与外部世界进行通信。所以转到您的WorkerRole设置。
一旦部署了工作者角色,您应该能够通过它的IP和先前配置的端口telnet进入服务器来确认端口是否已打开并可用。
从我们的客户端设置ActorSelection最重要的部分是,下面的IP / DNS地址必须与工作者角色中HOCON配置中的public-hostname设置中设置的IP / DNS匹配
ActorReferences.GameController =
ActorSystem.ActorSelection("akka.tcp://GameSystem@xx.xxx.xxx.xxx:8091/user/GameController")
.ResolveOne(TimeSpan.FromSeconds(3))
.Result;
为了完整性,这里是我的客户端HOCON配置:
akka {
loglevel = OFF
actor {
provider = "Akka.Remote.RemoteActorRefProvider, Akka.Remote"
debug {
receive = on
autoreceive = on
lifecycle = on
event-stream = on
unhandled = on
}
}
remote {
helios.tcp {
transport-class = "Akka.Remote.Transport.Helios.HeliosTcpTransport, Akka.Remote"
transport-protocol = tcp
enforce-ip-family = true
port = 0 //A port will be provided for us... not important as we won't be calling into the client externally
public-hostname = "yoursitename.azurewebsites.net" //Remember this is simply the DNS name of the client machine
hostname = "127.0.0.1"
}
}
}
我真的希望这可以帮助其他人。我真的没有找到很多描述Azure的Akka.NET部署的文档(没有将Actor系统部署到易变的IIS应用服务)。如果我能以任何方式改进答案,请告诉我。
