部署 – kestrel-hellomvc.service：步骤USER产生失败/usr/bin/dotnet：没有这样的过程

我在Nginx上发布了关于发布asp.net核心项目的教程 https://docs.microsoft.com/en-us/aspnet/core/publishing/linuxproduction

以前的步骤似乎都成功了,

但同时

systemctl start kestrel-hellomvc.service
systemctl status kestrel-hellomvc.service

我有

kestrel-hellomvc.service - Example .NET Web API Application running on Ubuntu

Loaded: loaded (/etc/systemd/system/kestrel-hellomvc.service; enabled; vendor preset: enabled)

有没有人知道解决方案,似乎我没有/usr/bin/dotnet文件夹

解决方法

我已经解决了问题,源文件夹所有者应该是www-data,有755权限
