ASP.NET Core Hosting in Linux Server: A Comprehensive Guide for Devs

Greetings Devs, as more and more businesses are moving towards cloud-based technologies, the need for cross-platform web development framework is increasing. ASP.NET Core is a popular choice for web developers due to its open-source and cross-platform capabilities. In this article, we will explore how to host an ASP.NET Core application in a Linux server.

Understanding ASP.NET Core

ASP.NET Core is a free, open-source, and cross-platform framework for building modern web applications. It is built on top of .NET Core, a modular platform that allows developers to use only the components they need from the .NET framework. ASP.NET Core provides several features such as built-in dependency injection, middleware pipeline, and support for various web protocol implementations.

To get started with ASP.NET Core, you need to download the .NET Core SDK and the ASP.NET Core runtime package. You can get them from the official .NET Core website or through your package manager.

Why Host ASP.NET Core in Linux Server?

While ASP.NET Core can be hosted on Windows Server, there are several benefits of hosting it on a Linux server. First, Linux servers are more stable and secure compared to Windows servers. Second, Linux servers are cost-effective and can handle more traffic than Windows servers. Third, Linux servers are easily scalable, making it an ideal choice for businesses that require a flexible hosting solution.

Getting Started with ASP.NET Core Hosting in Linux Server

Before we begin, make sure you have a Linux server up and running. You can choose any Linux distribution that supports .NET Core and ASP.NET Core. We recommend using Ubuntu or CentOS, as they are the most popular Linux distributions for hosting web applications.

Step 1: Install .NET Core and ASP.NET Core Runtime

The first step is to install the .NET Core SDK and the ASP.NET Core runtime on your Linux server. You can follow the official Microsoft documentation to install them.

Distribution	Command
Ubuntu 20.04	sudo apt-get update sudo apt-get install -y apt-transport-https sudo wget -q https://packages.microsoft.com/config/ubuntu/20.04/packages-microsoft-prod.deb -O packages-microsoft-prod.deb sudo dpkg -i packages-microsoft-prod.deb sudo apt-get update sudo apt-get install -y dotnet-sdk-5.0 aspnetcore-runtime-5.0
CentOS 8	sudo rpm -Uvh https://packages.microsoft.com/config/centos/8/packages-microsoft-prod.rpm sudo yum update sudo yum install -y dotnet-sdk-5.0 aspnetcore-runtime-5.0

Step 2: Create an ASP.NET Core Application

Once you have installed the .NET Core SDK and the ASP.NET Core runtime, you can create a new ASP.NET Core application. You can use the dotnet CLI to create a new application with the following command:

dotnet new webapp -n MyWebApp

This will create a new ASP.NET Core application named MyWebApp. You can navigate to the application directory and run the application with the following command:

cd MyWebApp
dotnet run

You should now be able to see the application running on your localhost.

Step 3: Publish the Application

Before you can deploy the application to your Linux server, you need to publish it. Publishing the application creates a self-contained executable that includes all the necessary runtime and framework dependencies. You can use the following command to publish the application:

dotnet publish -c Release -r linux-x64

This will create a new directory named publish that contains the published application.

Step 4: Deploy the Application to Linux Server

Now that you have published the application, you can deploy it to your Linux server. You can use any method to transfer the published application to your Linux server, such as FTP or SCP. Once you have transferred the application to your Linux server, you can navigate to the application directory and run the application with the following command:

cd publish
dotnet MyWebApp.dll

You should now be able to see the application running on your Linux server.

FAQs

Q1. Can I host ASP.NET Core application on a shared Linux hosting?

Yes, you can host ASP.NET Core application on a shared Linux hosting as long as the hosting provider supports .NET Core and ASP.NET Core runtime.

Q2. Can I host ASP.NET Core application on a Docker container?

Yes, you can host ASP.NET Core application on a Docker container. In fact, Docker is a popular choice for hosting ASP.NET Core application due to its scalability and portability.

Q3. Can I host ASP.NET Core application on a cloud platform?

Yes, you can host ASP.NET Core application on a cloud platform such as Microsoft Azure, Amazon Web Services, or Google Cloud Platform. These cloud platforms provide various hosting options such as virtual machines, container instances, and serverless functions.

Q4. Can I use a different web server instead of Kestrel?

Yes, you can use a different web server instead of Kestrel. ASP.NET Core supports various web servers such as Apache, Nginx, and IIS. You can use a reverse proxy server to forward the incoming requests to the web server.

Q5. How do I troubleshoot issues with my ASP.NET Core application?

You can use the logging and tracing capabilities of ASP.NET Core to troubleshoot issues with your application. You can also use various tools such as dotnet CLI, Visual Studio, or Azure DevOps to debug your application. Additionally, you can refer to the official Microsoft documentation or seek help from the developer community.
