Installing a .NET application on Linux can be beneficial for several reasons:

  1. Cross-Platform Compatibility: .NET Core, the cross-platform version of .NET, enables applications to run on multiple operating systems, including Linux. This increases the application's reach and usability across different environments.

  2. Performance and Reliability: Linux is known for its performance and stability. Running a .NET application on Linux can leverage these attributes, potentially leading to better application performance and reliability.

  3. Open Source and Community Support: Both Linux and .NET Core are open-source, meaning that they benefit from robust community support and continuous improvements. This can lead to better security, more features, and quicker bug fixes.

  4. Cost-Effectiveness: Linux can be a more cost-effective option for hosting applications, especially for enterprises or developers who are looking to reduce operating costs. Many Linux distributions are available for free, reducing the cost of software licenses.

  5. Integration with Existing Linux Infrastructure: For organizations already using Linux for their servers or other parts of their IT infrastructure, installing .NET applications on Linux can ensure seamless integration and management within their existing ecosystem.

  6. Modern Development Practices: .NET Core on Linux supports modern development practices and tools, including containerization with Docker, which is natively supported in Linux. This can facilitate more efficient development, testing, and deployment processes.

  7. Security: Linux is often praised for its security features. Running .NET applications on Linux can benefit from these security aspects, offering a more secure environment for applications.

In summary, installing a .NET application on Linux can offer advantages in terms of compatibility, performance, cost, integration, modern development practices, and security, making it an attractive option for many developers and organizations.

Follow the steps outlined to achieve this:

Install aaPanel
Optional but useful for maintenance:

The install script will complete within a few minutes and will install the hosting panel giving you valuable tools to maintain your sites.

wget -O install.sh http://www.aapanel.com/script/install-ubuntu_6.0_en.sh && sudo bash install.sh
Add Microsoft Install Manager Repository if not found
# Get Ubuntu version
declare repo_version=$(if command -v lsb_release &> /dev/null; then lsb_release -r -s; else grep -oP '(?<=^VERSION_ID=).+' /etc/os-release | tr -d '"'; fi)
# Download Microsoft signing key and repository
wget https://packages.microsoft.com/config/ubuntu/$repo_version/packages-microsoft-prod.deb -O packages-microsoft-prod.deb
# Install Microsoft signing key and repository
sudo dpkg -i packages-microsoft-prod.deb
# Clean up
rm packages-microsoft-prod.deb
# Update packages
sudo apt update
Install dotnet 6
sudo apt-get update && sudo apt-get install -y apt-transport-https aspnetcore-runtime-6.0
Install dotnet 7
sudo apt-get update && sudo apt-get install -y apt-transport-https aspnetcore-runtime-7.0
Install dotnet 8
sudo apt-get update && sudo apt-get install -y apt-transport-https aspnetcore-runtime-8.0
Create the service file
sudo nano /etc/systemd/system/kestrel-helloapp.service
The following example is a service file for the app:
Description=Example .NET Web API App running on Linux
ExecStart=/usr/bin/dotnet /var/www/helloapp/helloapp.dll
# Restart service after 10 seconds if the dotnet service crashes:
Enable the service
sudo systemctl enable kestrel-helloapp.service
sudo systemctl start kestrel-helloapp.service
sudo systemctl status kestrel-helloapp.service
Create the dotnet site in aaPanel

And make sure you set the reverse proxy to the port you configured for the dotnet app (default is 5001)

At this point, you can already deploy your website and browse to it.

If you are going to use MSSQL with Ubuntu, make sure to install it following these steps:

IMPORTANT: you must have an Ubuntu 20.04 machine with at least 2 GB of memory
Import the public repository GPG keys:
wget -qO- https://packages.microsoft.com/keys/microsoft.asc | sudo tee /etc/apt/trusted.gpg.d/microsoft.asc
Register the SQL Server Ubuntu repository:
sudo add-apt-repository "$(wget -qO- https://packages.microsoft.com/config/ubuntu/20.04/mssql-server-2022.list)"
Run the following commands to install SQL Server:
sudo apt-get update
sudo apt-get install -y mssql-server
After the package installation finishes, run mssql-conf setup and follow the prompts to set the SA password and choose your edition. As a reminder, the following SQL Server editions are freely licensed: Evaluation, Developer, and Express.
sudo /opt/mssql/bin/mssql-conf setup
Once the configuration is done, verify that the service is running:
systemctl status mssql-server --no-pager
Allow external connections through the firewall
sudo ufw allow 1433
Once you're done deploying, secure the server with these commands (optional for 22)
ufw deny 1433
ufw deny 22
ufw deny 21
ufw deny 20
