Learn How to Install Mono (Microsoft’s .NET Framework) in Red Hat Enterprise Linux Systems

Learn How to Install Mono (Microsoft’s .NET Framework) in Red Hat Enterprise Linux Systems.

Installing Mono on Red Hat Enterprise Linux systems can be a daunting task for many. With this step-by-step guide, you will learn how to install Mono on Red Hat Enterprise Linux systems quickly and easily. The Mono project is backed by Microsoft Corporation and is also a recognised part of the .NET foundation, which is comprised of the C# compiler, the mono runtime, the base class library, and the mono class library. This guide walks you through the necessary steps to get Mono installed on your system, configuring the environment variables, and running your first application with Mono. By following this guide, you can ensure that your system is optimized for running .NET applications with Mono.

Requirements

In order to complete this tutorial, the following is a list of items that may be needed or required. Please ensure you have these items before taking implementation action on this tutorial to ensure success:
1) A desktop or laptop with at least 4GB RAM, a dual-core processor, and at least 50GB of free disk space
2) A Linux-based operating system such as Rocky Linux, CentOS, Fedora, Almalinux, or Fedora
3) An SSH client such as Putty or the built-in MacOS / Linux terminal
4) The Mono package for your Linux operating system
5) A basic understanding of how to create .NET applications

Overview

1) Connect to your Linux computer via SSH and add the Mono repository
2) Install Mono onto your Linux server
3) Extra Mono packages that you can install
4) Compile and run mono programs in your Linux terminal
5) Conclusion.

Step 1: Connect to your Linux computer via SSH and add the Mono repository

The first step is to connect to your Linux Server or Desktop computer via SSH. If you are installing Mono directly on your PC you can simply open the built-in terminal app.If you are installing Mono on a remote / cloud-hosted server run the command below to connect to your server:

If you are using a Windows-based PC, you can download the Putty SSH client and use it to connect to your Linux Server.

Step 2: Install Mono onto your Linux Server

Install on Redhat Enterprise Linux / Rocky / Alma Linux 8 or CentOS

Run the commands below to install mono on Redhat Enterprise Linux / Rocky / Alma Linux 8 or CentOS. Copy, paste and run one command at a time:

Install on CentOS or Redhat Enterprise Linux 7

If your server is running Redhat Enterprise Linux 7 or CentOS 7, run the commands below to install Mono:

Install on Fedora 29 WorkStation or Server edition

To install Mono on Fedora WorkStation or Server edition, copy the commands below and run them on your server:

Install on Redhat Enterprise Linux 6 or Centos 6

Redhat enterprise linux 6 or CentOS 6 is also supported for this set up, to install on these operating systems, run the commands below:

If you would like to check the version details of your Mono package, you can simply run the command shown below :

Step 3: Extra Mono packages that you can install (optional)

Once you have installed Mono on your Redhat Enterprise Linux server, below are some optional extra packages that you can install. Some of the packages are
1) the mono-complete package which contains all the necessary components needed for deploying a Mono app
2) The xsp package which is a small web server needed for running ASP.NET applications.
3) The mono-dbg package which enabled debugging for various libraries in Mono.

Choose from the commands below to install a mono extra package

Step 4: Compile and run Mono programs in your Linux terminal

The final step is to test Mono just to be sure that you can build and run .NET-based applications. To do this we will build and execute a small program on the Mono server. Run the command below to create a file named firstrun.cs

Once the file is created copy and paste into the file the following code:

using System;
public class FirstCodeRun
{
    public static void Main(string[] args)
    {
        Console.WriteLine ("This is my first program. I learnt how to create it on billysoftacademy");
    }
}

Step 5: Compile and run mono applications in your Linux terminal

Compile the firstrun.cs program using the C sharp compiler. It will create a firstrun.exe executable file within your current working directory.

Finally, run the firstrun.exe executable file by using the mono system.

Conclusion

From here you can now start using mono to build great .NET or ASP.NET web applications, and services.
