在Ubuntu上托管NetCore应用程序

嘿，伙计们，我在Ubuntu上托管.net内核时遇到了一些问题，我可以使用以下命令很好地托管它：

dotnet /home/bourdain/website/FrutaMargemCore/bin/Release/netcoreapp2.0/FrutaMargemCore.dll

这可以很好地托管应用程序，我可以通过虚拟机的外部IP访问它，但它似乎将它锁定在某种会话状态，终端只是托管它，我需要终止进程以运行任何其他命令

info: Microsoft.AspNetCore.DataProtection.KeyManagement.XmlKeyManager[0]
      User profile is available. Using'/home/bourdain/.aspnet/DataProtection-Keys' as key repository; keys will not be encrypted at rest.
Hosting environment: Production
Content root path: /home/bourdain/website/FrutaMargemCore/bin/Release/netcoreapp2.0
Now listening on: http://localhost:5000
Application started. Press Ctrl+C to shut down.

关闭SSH连接将终止进程，应用程序将不再托管

我试过使用

dotnet run /home/bourdain/website/FrutaMargemCore/bin/Release/netcoreapp2.0/FrutaMargemCore.dll

但它随机抛出一个异常

Using launch settings from /home/bourdain/website/FrutaMargemCore/Properties/launchSettings.json...

Unhandled Exception: System.FormatException: Value for switch '/home/bourdain/website/FrutaMargemCore/bin/Release/netcoreapp2.0/FrutaMargemCore.dll' is missing.

我如何在ubuntu服务器上托管netcore内核，而不让它在我关闭SSH连接时终止？

您应该从创建如下服务文件开始：

sudo nano /etc/systemd/system/kestrel-yourApp.service

服务文件将包含以下内容：

[Unit]
Description=My ASPNET Core APP

[Service]
WorkingDirectory=/var/someFolder/yourApp
ExecStart=/usr/bin/dotnet /var/aspnetcore/yourApp/yourApp.dll
Restart=always
RestartSec=20
SyslogIdentifier=dotnet-example
User=yourUser
Environment=ASPNETCORE_ENVIRONMENT=Production
Environment=DOTNET_PRINT_TELEMETRY_MESSAGE=false

[Install]
WantedBy=multi-user.target

根据应用程序的上下文（如用户、路径等）调整参数。用户必须具有正确的权限

这将启动服务：

systemctl enable kestrel-yourApp.service

执行此操作只是为了检查其是否正在运行：

systemctl status kestrel-yourApp.service
