访问linux托管的ASP.NET Core 2.x webapp（无nginx）

Question

My ASP.NET Core 2.1 webapp works perfectly on my dev setup. Now I want to test it in production.

The production server is Ubuntu 18. I followed the instructions . I don't want to setup nginx yet, just do some quick tests, and the instructions say:

"Either configuration—with or without a reverse proxy server—is a valid and supported hosting configuration for ASP.NET Core 2.0 or later apps".

So I built and published my project: dotnet publish --configuration Release . Then on the server:

• install the dotnet runtime
• copied files to server ( /var/www/myapp )
• opened ports: sudo uwf allow 5000/tcp 80/tcp
• run dotnet MyApp.dll (also tried sudo dotnet MyApp.dll )

It runs without errors/warnings, and says it's listening on http://localhost:5000 .

On my local machine I tried http://serveripaddress (and http://serveripaddress:5000 ) but get nothing ("can't connect"). I can access that server with ssh, sftp, etc - only http isn't working.

What am I doing wrong?

Answer 1

Found the problem. I needed to use:

sudo ASPNETCORE_URLS="http://0.0.0.0:5000" dotnet MyApp.dll

Then it logs Now listening on: http://0.0.0.0:5000 . And I can access that from a remote client.

Answer 2

the host default bind is 127.0.0.1 , so you can only access the app locally. if you want to access it from Network, please add --urls parameter. for example :

for development, you can run:

dotnet run --urls http://0.0.0.0:5000

and for deployed project, you can run:

dotnet MyApp.dll --urls http://0.0.0.0:5000

The dotnet core sdk I use is version 2.1.400.
