我有一個庫存的、幾乎未修改的 Visual Studio 模板 ASP.NET Core 應用程序,我試圖在 Ubuntu 18.04 上運行。我已經遵循了這個指南:https://docs.microsoft.com/en-gb/aspnet/core/host-and-deploy/linux-apache?view=aspnetcore-3.1。
經過一段時間的碰碰後,我成功地讓 ASP.NET 服務運作起來。但是,當我訪問我的頁面時,我看到 503 服務不可用錯誤。
我的阿帕契配置:

systemctl status tpanel
這是(我的 ASP 守護程式)的結果:

但就像我說的,當我訪問時,example.com/panel
我看到 503 錯誤。我網站的其他部分運作良好。
其他資訊:
- 我有另一個不相關的應用程式正在運行,它使用 5001 端口,但我用其他東西替換了它,所以這應該不是問題
33138
我是否將應用程式的連接埠設定為或似乎並不重要5001
,它不會改變任何東西
答案1
launchSettings.json
是 VS Code 的事情。它在這裡沒有任何作用。
您的應用程式正在連接埠 5000 (HTTP) 和 5001 (HTTPS) 中運行,這是我們在日誌中看到的不可否認的事實:
Dec 13 10:16:22 vps-example dotnet[2765]: info: Microsoft.Hosting.Lifetime[0] Dec 13 10:16:22 vps-example dotnet[2765]: Now listening on: http://localhost:5000 Dec 13 10:16:22 vps-example dotnet[2765]: info: Microsoft.Hosting.Lifetime[0] Dec 13 10:16:22 vps-example dotnet[2765]: Now listening on: https://localhost:5001
Apache 設定為連接到連接埠 33138 上的應用程式:
ProxyPass /panel https://localhost:33138/ ProxyPassReverse /panel https://localhost:33138/
應用程式不會偵聽該端口,因此 503 是由 Apache 發送的,而不是 ASP.NET Core 發送的。
修復應用程式的偵聽連接埠。例如,inappsettings.json
或 via ASPNETCORE_URLS
。有更多資訊可供參考這裡。
順便說一下, 中的尾部斜線不符ProxyPass
。這可能會導致其他問題。
