I’ve gotten to the point in my web development career where I can no longer avoid the words VirtualBox, Vagrant, and Docker. Thanks to my friend Timm Stelzer, I finally got over my fear of the unknown and delved into the world of virtual machines via Vagrant and VirtualBox.
Now that I’ve finally used them, I can see how fun and useful they are, and since I’ve just set everything up myself in 2017 with the most up-to-date installations I could find, I can share what I’ve learned with you.
The only prerequisite to this article is command line knowledge, and it is mandatory. This article that I wrote, How to Use the Command Line, will tell you everything you need to know, from moving around directories, creating files, and
sshing into servers. If you’re not familiar with any of that, please read the aforementioned article.
In this tutorial, we will learn:
- What VirtualBox is
- What Vagrant is
- How to use Vagrant and VirtualBox in tandem to set up a local Ubuntu installation
- How to connect to the Ubuntu server we create
VirtualBox is basically inception for your computer. You can use VirtualBox to run entire sandboxed operating systems within your own computer.
Vagrant is software that is used to manage a development environment. Through the command line, you can grab any available OS, install it, configure it, run it, work inside of it, shut it down, and more.
Using VirtualBox and Vagrant, you can simulate the production environment of your app or website. For example, if you’re using Digital Ocean or AWS to run a Virtual Private Server (VPS) in the cloud running Ubuntu, PHP, and MySQL, you can install your local version to have all the same versions of that software, while keeping your own computer’s software untouched. This can reduce and eliminate bugs and errors that result from trying to develop code for a production server on an environment that does not match.
In this tutorial, we’re going to install Vagrant and VirtualBox, and install Ubuntu Server. We’re going to connect to the Ubuntu server though
ssh to confirm that everything is running properly.
After this tutorial, learn to install a LAMP server on the environment we create.
Step 1 – Install Virtual Box and Vagrant
Go to the VirtualBox download page, choose your operating system (Windows or macOS) and download and install the software.
I clicked OS X and the download started.
Go to the Vagrant download page, choose your operating system (Windows or macOS) and download and install the software.
Again, I chose Mac OS X.
Step 2 – Install Ubuntu Server with Vagrant
Create a directory for your virtual host to live. I created a VirtualMachines directory (which will potentially contain all of my virtual machine installations), and made a new directory within called ubuntu for this specific installation to live. The whole path is as follows:
Your path will be slightly different for Windows, using
C:/, but otherwise will be the same idea.
Install Ubuntu Box
You can Discover Vagrant Boxes via the Vagrant Cloud.
ubuntu/trusty64 is the most popular box (machine), with nearly 30 million installs and updated within the last day. This is the one we’ll be using.
In Terminal (Mac) or Git Bash (or whatever shell you’re using on Windows), type the following to install Ubuntu Server 14.04.
vagrant box add ubuntu/trusty64
After a few moments, this will be the output to let you know it’s successful.
==> box: Loading metadata for box 'ubuntu/trusty64' box: URL: https://vagrantcloud.com/ubuntu/trusty64 ==> box: Adding box 'ubuntu/trusty64' (v20170619.0.0) for provider: virtualbox box: Downloading: https://app.vagrantup.com/ubuntu/boxes/trusty64/versions/20170619.0.0/providers/virtualbox.box==> box: Successfully added box 'ubuntu/trusty64' (v20170619.0.0) for 'virtualbox'!
Now initialize the new
vagrantin your VirtualMachines/ubuntu directory with the
vagrant init ubuntu/trusty64`Vagrantfile` has been placed in this directory. You are now ready to `vagrant up` your first virtual environment! Please read the comments in the Vagrantfile as well as documentation on `vagrantup.com` for more information on using Vagrant.
Finally, get Ubuntu up and running with the
vagrant upBringing machine 'default' up with 'virtualbox' provider... ==> default: Importing base box 'ubuntu/trusty64'... ... ==> default: Machine booted and ready!
When you see “Machine booted and ready!”, everything is good to go!
Fixing Guest Additions Error
This is great, and all set up. However, you may have gotten this error:==> default: Checking for guest additions in VM... default: The guest additions on this VM do not match the installed version of default: VirtualBox! In most cases this is fine, but in rare cases it can default: prevent things such as shared folders from working properly. If you see default: shared folder errors, please make sure the guest additions within the default: virtual machine match the version of VirtualBox you have installed on default: your host and reload your VM.
This might not be a problem, but let’s make sure it doesn’t become a problem. First, use the
haltmethod to shut down your currently running Vagrant.
Let’s quickly install a plugin called
vbguestto fix this error.
vagrant plugin install vagrant-vbguest
It will run through some more commands, and most likely the above error will still persist. Let’s reload the Vagrant machine with the
Now the errors will be gone.[default] GuestAdditions 5.1.22 running --- OK.
What about VirtualBox?
Looks like we didn’t use VirtualBox for anything at all. But go ahead and open up the VirtualBox application. This is what you will see running:
As you can see, VirtualBox is letting us know that Ubuntu is running properly. We don’t really need to know much more about it at this point.
Step 3 – SSH into Ubuntu
Now we have this Ubuntu operating system set up on our computer, but how do we access it? Just like you would access any remote Linux server through the command line, you will do the same with Vagrant. Run
vagrant sshto securely enter the Ubuntu virtual machine.
When you login, you will see something along these lines.Welcome to Ubuntu 14.04.5 LTS (GNU/Linux 3.13.0-123-generic x86_64) * Documentation: https://help.ubuntu.com/ System information as of Sun Jul 2 21:30:05 UTC 2017 System load: 0.15 Processes: 84 Usage of /: 3.6% of 39.34GB Users logged in: 0 Memory usage: 24% IP address for eth0: 10.0.2.15 Swap usage: 0% Graph this data and manage this system at: https://landscape.canonical.com/ Get cloud support with Ubuntu Advantage Cloud Guest: http://www.ubuntu.com/business/services/cloud New release '16.04.2 LTS' available.

You’re in! You now have a complete Ubuntu Server installation running through VirtualBox on your computer, and you’re connected to it. Type
exitat any time to exit out of the server, and
vagrant haltto shut it down.
Here is a review of the commands we used with Vagrant today.
Command Purpose vagrant box add ORG/BUILD Add a new virtual machine vagrant init ORG/BUILD Initialize virtual machine vagrant up Start up virtual machine vagrant reload Restart virtual machine vagrant halt Shut down virtual machine vagrant ssh SSH into the virtual machine
Note: All these commands must be done locally from the directory in which you want the virtual machine to be installed, except
vagrant box add.
As a review, VirtualBox is the software that runs the operating system, and vagrant will give you the methods to manage them. You can also think of vagrant as a package manager that has a repository of different operating systems to use.
Vagrant and VirtualBox can be used to create a local environment that matches the production environment of your server.
Move on to Part 2: Setting up LAMP (Linux, Apache, MySQL, and PHP) from the Ubuntu Server environment we created, and how to access it from your local computer.
