Install VirtualBox and phpVirtualBox on CentOS 7

Install VirtualBox and phpVirtualBox on CentOS 7

VirtualBox is a free and open-source hypervisor, developed by Oracle Corporation. VirtualBox supports all popular operating system platforms. VirtualBox is also used as the Provider for Vagrant, a server orchestration software.

phpVirtualBox is a web interface for administration of VirtualBox servers. phpVirtualBox is a free and open source web application. phpVirtualBox is written in PHP thus requires a Web Server with PHP language support for deployment.

In this article, we are installing VirtualBox and phpVirtualBox on CentOS 7 server.

Install VirtualBox and phpVirtualBox on CentOS 7

Environment Specification:

We have configured a CentOS 7 virtual machine with following specifications.

  • CPU - 3.4 Ghz (2 cores)
  • Memory - 2 GB
  • Storage - 20 GB
  • Operating System - CentOS 7.6
  • Hostname - virtualbox-01.example.com
  • IP Address - 192.168.116.185/24

 

Installing VirtualBox on CentOS 7:

Connect with virtualbox-01.example.com using ssh as root user.

Install VirtualBox prerequisite packages using yum command.

# yum install -y kernel-devel-$(uname -r) kernel-headers gcc make perl wget

The vboxdrv.service requires same kernel-devel modules as of running Kernel. Otherwise, after installation vboxdrv.service will throw errors. Therefore, we have used $(uname -r) with above yum command

VirtualBox is distributed via its own yum repository. Therefore, we have to install VirtualBox yum repository first and then we will be able to install VirtualBox software.

Download and add VirtualBox yum repository in our CentOS 7 server.

# wget https://download.virtualbox.org/virtualbox/rpm/el/virtualbox.repo -O /etc/yum.repos.d/virtualbox.repo

Now we can install VirtualBox using yum command.

# yum install -y VirtualBox-6.0.x86_64

vboxdrv.service is automatically enabled and started by VirtualBox installation process.

Check status of vboxdrv.service.

VirtualBox 6.0 has been installed on our CentOS 7 server.

 

Installing VirtualBox Extension Pack on CentOS 7:

VirtualBox is splitted into two components.

  • Base Package
  • Extension Packs

We have already installed VirtualBox Base Package above. Now, we are installing VirtualBox Extension Pack to extend the functionality of VirtualBox software.

VirtualBox Extension Pack is available at VirtualBox Official Download Page. It consist of a single universal package that supports all platforms.

We are downloading it using wget command.

Successfully installed "Oracle VM VirtualBox Extension Pack".

VirtualBox Extension Pack have been successfully installed on CentOS 7 server.

 

Configure vboxweb-service on CentOS 7:

phpVirtualBox admin communicate to our VirtualBox server using vboxweb-service. Therefore, we have to configure vboxweb-service before installing phpVirtualBox.

Create a user that will run the vboxweb-service process.

# useradd vbox
# passwd vbox
Changing password for user vbox.
New password:
BAD PASSWORD: The password is shorter than 8 characters
Retype new password:
passwd: all authentication tokens updated successfully.

Create a configuration file for vboxweb-service.

# echo "VBOXWEB_USER=vbox" > /etc/default/virtualbox
# echo "VBOXWEB_HOST=localhost" >> /etc/default/virtualbox

Restart vboxweb-service.

# systemctl restart vboxweb-service.service

Allow vboxweb-service port in Linux firewall.

# firewall-cmd --permanent --add-port=18083/tcp
success
# firewall-cmd --reload
success

 

Installing phpVirtualBox on CentOS 7:

phpVirtualBox is a PHP based web application. Therefore, it can be deployed on a web server with PHP language support.

We are installing Apache HTTP server and PHP 5.4 along with other required packages using yum command.

# yum install -y httpd php php-soap php-xml

Enable and start Apache service.

# systemctl enable httpd.service
Created symlink from /etc/systemd/system/multi-user.target.wants/httpd.service to /usr/lib/systemd/system/httpd.service.
# systemctl start httpd.service

Allow HTTP service in Linux firewall.

# firewall-cmd --permanent --add-service=http
success
# firewall-cmd --reload
success

phpVirtualBox is free and open source web interface for VirtualBox. phpVirtualBox is available at Github.

# cd /tmp

Extract master.zip file to Apache document root.

# unzip master.zip -d /var/www/html/

Rename /var/www/html/phpvirtualbox-master directory for easy accessibility.

# mv /var/www/html/phpvirtualbox-master /var/www/html/phpvirtualbox

Rename phpVirtualBox configuration file as follows.

# mv /var/www/html/phpvirtualbox/config.php-example /var/www/html/phpvirtualbox/config.php

Obtain the username and password defined in config.php file.

# grep -e \$username -e \$password /var/www/html/phpvirtualbox/config.php
var $username = 'vbox';
var $password = 'pass';

The above values must match with the OS user vbox, that we have created above.

We have already created the OS user with the same username and password, otherwise you have to edit config.php to match it.

(Note: We are using an easy password for the sake of simplicity, but you are recommended to set a strong password here.)

Set SELinux boolean, so the Apache can access other network services.

# setsebool -P httpd_can_network_connect on

Browse URL http://virtualbox-01.example.com/phpvirtualbox/ in a client's browser.

01-phpvirtualbox-centos-7-login

Login with phpVirtualBox default username/password (i.e. admin/admin).

02-phpvirtualbox-centos-7-compatibility-error

After login phpVirtualBox web interface may display a compatibility warning and advise us to install a latest version of phpVirtualBox.

Since, we are already installing the latest version of phpVirtualBox therefore, we have no other option to ignore this warning until a new version of phpVirtualBox is available.

03-phpvirtualbox-centos-7-dashboard

We are now at the Dashboard of the phpVirtualBox web interface.

Click on New to create a new virtual machine.

04-phpvirtualbox-centos-7-create-virtual-machine

Provide virtual machine name and select operating system thereon and click on Next >>.

05-phpvirtualbox-centos-7-memory

Set memory size and click on Next >>.

06-phpvirtualbox-centos-7-hard-disk

Select hard disk setting and click on Create.

09-phpvirtualbox-centos-7-file-location

Select file location and size and click on Next >>.

10-phpvirtualbox-centos-7-dashboard

Virtual machine has been created successfully.

One last thing is to change the default password of admin user.

Click on File > Change Password.

11-phpvirtualbox-centos-7-change-password

Set a strong password for admin user.

We have successfully installed VirtualBox and phpVirtualBox on CentOS 7 server.
