【英文标题】：Service Fabric Reverse Proxy - 404 - FABRIC_E_SERVICE_DOES_NOT_EXIST

【发布时间】：2018-02-07 02:56:48

【问题描述】：

是否有人在使用 ServiceFabricIntegrationOptions.UseUniqueServiceUrl 时遇到 Service Fabric 反向代理的间歇性问题 (404 - FABRIC_E_SERVICE_DOES_NOT_EXIST)。 该服务确实存在。 我们仔细检查了“外壳”。这不是外壳问题。 相同的请求将在某些节点上工作，但在其他节点上失败。

我们有一个在 Azure（版本 5.7.198.9494）中运行的 5 节点服务结构集群。我们有许多使用 ASP.NET Core 1.1 构建的无状态服务 (Web API)，每个服务都在自己的应用程序中。

因为它们只能从集群内部访问，所以每个 Web API 服务只有 1 个实例，并且使用 Kestrel 作为主机服务器配置为“UseServiceFabricIntegration”和“ServiceFabricIntegrationOptions.UseUniqueServiceUrl”。为了简化发现，我们决定在与这些服务通信时利用反向代理。

在我们注意到反向代理日志 (ETW Microsoft-ServiceFabric:4:0x4000000000000020) 中出现间歇性 404 (FABRIC_E_SERVICE_DOES_NOT_EXIST) 之前，一切似乎都运行良好。经过一番调查，我们发现对反向代理的相同 HTTP 请求可以在某些节点上工作，但在其他节点上却不行。即：

在节点 1 上打开 RDP 会话； 打开 Powershell 并运行“wget http://localhost:19081/CoreApi.Currency.Application/Currency.Web/?s=USD”； 结果：200（正常） 在节点 2 上重复步骤 1-2； 结果：404（未找到）； 404 可能发生在 1、2 或 3 个节点上，而在另一个节点上成功 节点；

有时重新部署失败的无状态服务可以暂时解决问题。 重新启动“客户端”节点（不托管服务的节点）会使该节点的反向代理失败并显示 404。 在故障节点上运行 powershell 命令“Get-ServiceFabricApplicationName -ServiceName fabric:/CoreApi.Currency.Application/Currency.Web”将解决问题，直到重新启动节点。

有人遇到过这种问题吗？

“Vislor”于 2016 年 12 月 15 日对“https://docs.microsoft.com/en-us/azure/service-fabric/service-fabric-reverseproxy”发表的评论描述了一个非常相似的问题。

提前致谢。

更新 2： 在 github.com/Azure/service-fabric-issues/issues/429 上打开了一个带有重现步骤的问题

【问题讨论】：

我很久以前就遇到过类似的问题（如果我没记错的话）。当我的分区无状态服务部署为 Singleton 时，我遇到了这个问题。

【参考方案1】：

在将 Service Fabric 升级到 6.0.219.9494 后，我遇到了完全相同的问题 5.7.198.9494，现在问题已为我解决。

感谢 Mark 在 github 中提出 bug - 问题已解决。

所以，本质上：

Service Fabric Explorer 报告没有错误/警告 404 FABRIC_E_SERVICE_DOES_NOT_EXIST 错误仅发生在某些节点上（在我的场景中，4/5 个节点工作正常）。 此 HTTP 错误是由 Service Fabric 反向代理服务中的 bug 引起的 解决。 Microsoft 已在 6.0 CU1 中修复此问题。截至今天，当前可用的最新版本是 6.0.219.9494 - 迄今为止的问题 对我来说似乎是固定的。
