Vagrant is a handy and easy-to-use Virtual Machine tool that can be used within your command-line interface. In a nutshell, it makes it easy to create and configure lightweight, reproducible developer environments.

In this mini course, you will learn all about virtualization. You will learn how to set up a Vagrant environment, build your own VM, as well as Vagrant commands which you can use from the command line.

In the latter half of the course, you will learn how to work with vagrantfile, networking, and data sharing. In all, this is your crash course for understanding the fundamentals of Vagrant.

A Guide to Vagrant and Virtual Machines

# Install VirtualBox

Before running your first Vagrant VM, a Virtual Machine software needs to be installed.
We’ll be using VirtualBox because it’s easy to get started with. If you're comfortable with any other software, feel free to use it. 

## For Windows users

For Windows, you can directly install the setup from the following link: [Download VirtualBox](https://www.virtualbox.org/wiki/Download_Old_Builds_6_0).

## For Linux users

Linux users can install VirtualBox either using the command line interface or by downloading directly from the [VirtualBox](https://www.virtualbox.org/wiki/Downloads) website.

We'll be using the command line interface to install VirtualBox.

```
$ sudo apt-get update
```
```
$ sudo apt-get install virtualbox
```
```
$ sudo apt-get install virtualbox-ext-pack
```
With these 3 commands, VirtualBox should be installed successfully.

## For Mac users

Mac users can download VirtualBoxhere: [Download VirtualBox](https://www.virtualbox.org/wiki/Downloads).

# Install Vagrant
> This is performed on an Ubuntu Distro. If you are using a RedHat-based Distro, just use your package manager, and you'll be good to go.   
1. In an Ubuntu-based Distro - `apt manager` is used.
2. In a Redhat-based Distro - either `Yum` or `dnf` is used.


## Install Vagrant on Linux

*Ubuntu-Based Distro*:
```
$ sudo apt-get install vagrant
```

*Redhat-Based Distro*:
```
$ sudo yum install vagrant
```
If you are using version 8+:
```
$ sudo dnf install vagrant
```

You can check the version after installing.
```
$ vagrant -v
Vagrant 2.2.6
```

## Install Vagrant on Windows
Windows users can directly install the setup with the following link:

[Download Vagrant](https://www.vagrantup.com/downloads.html).

After a successful installation, you can use Vagrant via the command-line tool or Windows PowerShell (terminal).

## Install Vagrant on MacOS

Mac users can use the brew manager to install Vagrant.
```
$ brew cask install vagrant
```
The main difference between Mac and Linux is the use of package managers; both support different packages to install software. Apart from that, the work will be done the same as in the Linux environment.

In this lesson, we'll be learning how to install Vagrant on different platforms.
