여기 결과가 있습니다

하지만 이것을 systemd에 추가하면 예를 들어 자동으로 시작되도록 Linux 서비스처럼 작동하게 만들려고 합니다.

다음 구성으로

[Unit]
    Description=prereg application

    [Service]
    WorkingDirectory=/www/web/prod/prereg.example.org/prereg-sample/WebApplication/bin/Debug/netcoreapp1.1/
    ExecStart=/usr/bin/dotnet /www/web/prod/prereg.example.org/prereg-sample/WebApplication/bin/Debug/netcoreapp1.1/WebApplication.dll
    Restart=always
    RestartSec=10                                          # Restart service after 10 seconds if dotnet service crashes
    SyslogIdentifier=prereg-sample
    User=webadmin
    Environment=ASPNETCORE_ENVIRONMENT=Production

    [Install]
    WantedBy=multi-user.target

이런 오류가 발생합니다. 왜 이런 일이 발생하는지 아시나요?

나는 너무 멍청하다.

The configuration file 'appsettings.json' was not found and is not optional.

이는 폴더가 잘못 설정되었음을 의미합니다. 폴더는 /publish여야 하며 appsettings.json이 있습니다. 그리고 그것은 효과가 있었습니다. 그리고 개발자는 MongoDb 연결 문자열이 포함된 구성 파일을 추가하지 않았습니다.
