I was following the tutorial https://learn.microsoft.com/en-us/aspnet/core/publishing/linuxproduction on publishing asp.net core project on Nginx, the previous steps all seem successful, but while
systemctl start kestrel-hellomvc.service
systemctl status kestrel-hellomvc.service
I got
kestrel-hellomvc.service - Example .NET Web API Application running on Ubuntu

Does anyone know the solution, it seems I don't have the /usr/bin/dotnet
folder.
I've solved the problem, the source folder owner should be www-data
, having 755 permission. The Apache user is called www-data
on Ubuntu, and apache
on CentOS. So specifically set User=www-data
in kestrel-hellomvc.service
if running on Ubuntu, thanks to Jeppe's comment.
Also, if you have added users in /etc/systemd/system/gunicorn.service
before, removing these users might resolve this issue as well.
The same error message will be displayed if the user defined in your service file does not exist, regardless of the permission on the web app folder.
In file /etc/systemd/system/gunicorn.service, I had added user. The issue got resolved when I removed the user.

After many hours, the answer for me was "yum reinstall systemd"
