Manage Headless VirtualBox Host on Ubuntu Linux with phpVirtualBox

A few days ago, we described how to install VirtualBox 5.2 on a headless Ubuntu 16.04 LTS server. Headless servers are those you’re not directly connected to using monitors and usually sit in remote locations.

With VirtualBox installed on a headless server, you’ll need to tool to help create and manage virtual guest machines easily. One can use a remote desktop connection as we described in our previous post, but if you need to manage multiple guest machines, then phpVirtualBox is the way to go.

Again, Virtualization software like VirtualBox and VMware Workstation Pro or VMware Players allow users to run multiple guest operating systems simultaneously on a single host computer.

We’ve also described instructions to install this popular virtualization software on Ubuntu and Windows systems on this website.

To get started with managing VirtualBox headless servers via phpVirtualBox, continue below:

Prerequisites – Install VirtualBox

Before you can install phpVirtualBox, you must first install VirtualBox. The link below shows you how to do just that.

Now that VirtualBox is installed, your next step is to get phpVirtualBox installed.

Install Apache2 HTTP Server

After installing VirtualBox as described in our previous post, run the commands below to install the Apache2 HTTP server.

sudo apt install apache2

Install PHP 7.1 and Related Modules

PHP 7.1 isn’t available on Ubuntu default repositories… to install it, you will have to get it from third-party repositories.

Run the commands below to add the below third party repository to upgrade to PHP 7.1

sudo apt-get install software-properties-common
sudo add-apt-repository ppa:ondrej/php

Then update and upgrade to PHP 7.1

sudo apt update

Run the commands below to install PHP 7.1 and related modules.

sudo apt install php7.1 libapache2-mod-php7.1 php7.1-common libapache2-mod-php7.1 php7.1-mbstring php7.1-soap php7.1-xml php7.1-mysql php7.1-cli

After installing PHP 7.1 modules, run the commands below to open the Apache2 PHP default configuration file.

sudo nano /etc/php/7.1/apache2/php.ini

Then add the lines below just before Dynamic Extensions

extension=json.so
extension=soap.so

Save the file and exit.

Reload Apache2 HTTP Server

sudo systemctl reload apache2.service

Install phpVirtualBox

Finally, run the commands below to download the phpVirtualBox package

cd /tmp && wget https://sourceforge.net/projects/phpvirtualbox/files/phpvirtualbox-5.0-5.zip

After downloading, run the commands below to unzip the package, and copy it to the Apache2 default document root directory.

unzip phpvirtualbox-5.0-5.zip
sudo mv phpvirtualbox-5.0-5 /var/www/html/phpvirtualbox

Next, create a phpVirtualBox configuration file from its sample file by running the commands below.

sudo cp /var/www/html/phpvirtualbox/config.php-example /var/www/html/phpvirtualbox/config.php

Create a phpVirtualBox dedicated user account

phpVirtualBox requires a dedicated user account to manage the VirtualBox. For that, you need to create a service account.

To create a service account called vbox and add the user to the vboxusers group. by running the commands below and running the second line to create a new password.

sudo useradd -m vbox -G vboxusers
sudo passwd vbox

Next, set the permissions for the phpVirtualBox directory for the vbox user

sudo chown -R vbox:vboxusers /var/www/html/phpvirtualbox
sudo chmod -R 755 /var/www/html/phpvirtualbox

Setup phpVirtualBox connection

The final step is to configure the phpVirtualBox user connection. This can be done by opening its default configuration file and adding phpvbox user to the settings.

Open and edit the file by running the commands below:

sudo nano /var/www/html/phpvirtualbox/config.php

Then fill in the user account for phpvbox as shown below.

/* Username / Password for system user that runs VirtualBox */
var $username = ‘vbox‘;
var $password = ‘vbox_password‘;
var $location = ‘http://localhost:18083/’;

Next, run the commands below to open VirtualBox config file in the /etc/default directory.

sudo nano /etc/default/virtualbox

Then add these lines at the end of the file, then save it. This allows VirtualBox SOAP API service to run as vbox.

VBOXWEB_USER=vbox
VBOXWEB_HOST=localhost

Start the phpVirtualBox service account by running the commands below.

sudo systemctl enable vboxwebsrv.service
sudo systemctl start vboxwebsrv.service
sudo systemctl reload apache2.service

Restart the Apache2 server, then browse to the host via IP or hostname followed by /phpvirtualbox

http://example/phpvirtualbox
virtualbox ubuntu install

This is how to manage VirtualBox remotely.

Enjoy!
