在 Linux 上運行應用程序時連接到 MSSQL Server 2017 超時
[英]Timeout connecting to MSSQL Server 2017 when application running on Linux
問題描述
我最近啟動了一個 ASP.NET Core Web 應用程序 (WebAPI)，使用 Entity Framework Core 進行數據庫通信，只要我在開發環境中的筆記本電腦上運行該應用程序，一切都運行得非常順暢。
為了托管網絡應用程序和數據庫，我使用的是 Ubuntu 服務器（16.04.3 LTS）。 我安裝了最新的 SQL 服務器（Microsoft SQL Server 2017 (RC2) - 14.0.900.75 (X64)），只要應用程序在 Windows 上運行，我就可以從我的應用程序連接到它。 但是，在 Ubuntu 上使用相同的代碼和連接字符串，所有查詢都會超時。 我得到以下輸出（異常/堆棧跟蹤）：

Connection id "0HL6RV4D2F9I6": An unhandled exception was thrown by the application.

Request finished in 35515.1854ms 500
我的代碼中發生異常的行是：
var teamGameState = ctx.GeneratedGameStates.First(x => x.TeamId == teamId);
該表只有一個條目，查看 SSMS 中的活動監視器，我可以看到翻譯后的 SQL 類似於 (SELECT TOP 1 * FROM ...) 並且查詢需要 35 秒。
我一直在閱讀有關其他人在嘗試使用在 Windows 中運行良好的相同代碼從 Linux 連接到 SQL Server 時遇到類似問題的信息，但我找不到解決方案。
有沒有其他人遇到過這個問題，更重要的是有人解決了這個問題嗎？

我認為這是重復的： https : //github.com/aspnet/EntityFrameworkCore/issues/5989
那里的解決方案：更新服務器軟件，因為您使用的是 RC2。
