A guide to asp.net core in Linux

In this article, I will show how we can start host asp.net applications in the Linux platform.

I used this following application https://github.com/sajidur/Donor , You can also be used this repo

Here I used RedHat Enterprise you can also be used Ubuntu.

So let's prepare our server to host the applications with follow below step

1. Install any SSH Client to access your server. You can use PuTTY . Download from here https://www.putty.org/
2. Install any FTP Client. You can use WinSCP. Download from here https://winscp.net/eng/docs/guide_install
3. Now follow this link to install .net core SDK/runtimes https://access.redhat.com/documentation/en-us/net_core/3.1/html/getting_started_guide/gs_install_dotnet

We are done. So let's focus on our repository

First, we need to publish our .net core app for Linux.

We can use Visual studio published options. To create a publish profile with the following types

Or you can use the command

$ dotnet publish -f netcoreapp3.1 -c Release

Secondly, After publish we will upload our publish folder to the server with WinSCP(or any FTP client) and navigate to the folder with SSH

After that run following command to start your applications. Application will be running in Kestral server

$ scl enable rh-dotnet22 bash
$ dotnet donor.dll

So we are done. Let's browse our application in the browser

Now the problem is when you close/exit your ssh application will stop. So we will use tmux to hold our session running.

To do that first we need to setup tmux in server with following the link below

And also your application need to run after an open session with tmux in your ssh client.

$ tmux new -s [name]
$ scl enable rh-dotnet22 bash
$ dotnet donor.dll

Now close your session with Cltr+d and check your application still running.

You can reuse this session or kill by the following command

$ tmux new -s [name]
$ tmux kill-session -t [session name/index]
$ tmux attach-session -t my_session

Some important basic command for non linux user

sudo fuser -k 8000/tcp
