VirtualBox is open source, and it is supported across all platforms. It can be downloaded directly from www.virtualbox.org/wiki/Downloads.

Now, we will proceed to set up a Linux virtual machine. We have selected Ubuntu server 12.04.2 LTS for its ease of use and widely available support. First, download the ISO file from www.ubuntu.com/download/server; either 64-bit or 32-bit versions will work.

To create a new Linux virtual machine, perform the following steps:

The newly created box will appear on the left-hand side navigation menu, but before we start our recently created VM, we need to make some changes:

At this point, we have successfully installed and configured our VirtualBox instance and are now ready to boot our new virtual machine for the first time. To do this, just select the VM in the left sidebar and click on the Start button at the top.

A new window will pop up with an interface to the VM. Ubuntu will take a few minutes to boot up.

Once Ubuntu has finished booting up, we will see two menus. The first menu will allow us to select the language, and the second one is the main menu that provides several options. In our case, we just want to proceed with Install Ubuntu Server:

We should now see the Ubuntu installation wizard, which will ask for our language and keyboard settings. After selecting the appropriate settings for our country and language, the installer will proceed to load all the necessary packages in the memory. This can take a few minutes.

Ubuntu will proceed to configure our main network adapter, and once the automatic configuration is done, we will be asked to set up the hostname for the virtual machine. We can leave the hostname to the default settings.

The next screen will request that we enter the full name of our user; for this example, let's use Magento Developer.

Next, we will be asked to create a username and password. Let's use magedev as our username.

Let's set magento2013 as our password.

On the next screens, we will be asked to confirm our password and set up the correct time zone. After entering the right values, the installation wizard will show the following screen, asking about our partition settings:

In our case, we want to select Guided – use entire disk and set up LVM; let's confirm that we are partitioning our virtual disk.

We will be asked to confirm our changes a final time; select Finish partitioning and Write changes to the disk.

The installation wizard will ask us to select predefined packages to install; one of the available options is LAMP server.

Although this is highly convenient, we don't want to install the LAMP server that comes prepackaged with our Ubuntu CD; we will be installing all the LAMP components manually, to guarantee that they are set up to specific needs and are up to date with the latest patches.

However, for this, we will need an SSH server; select OpenSSH server from the list and click on Continue.

The installation of Ubuntu is complete, and it will reboot into our newly installed virtual box.

We are almost ready to proceed with the installation of the rest of our environment, but first, we need to update our package manager repository definitions, log in to the console, and run the following command:

$ sudo apt-get update

APT stands for Advance Packaging Tool and is one of the core libraries included with most Debian GNU/Linux distributions; apt greatly simplifies the process of installing and maintaining software on our systems.

Once apt-get has finished updating all the repository sources, we can proceed with the installation of the other components of our LAMP server.

Apache is an HTTP server. Currently, it is used to host over 60 percent of the websites on the Web and is the accepted standard for the running of Magento stores. There are many guides and tutorials available online in order to fine-tune and tweak Apache2 to increase Magento's performance.

Installing apache is as simple as running the following command:

$ sudo apt-get install apache2 -y

This will take care of installing Apache2 and all the required dependencies for us. If everything has been installed correctly, we can now test it by opening our browser and entering http://192.168.36.1/.

By default, Apache runs as a service and can be controlled with the following commands:

$ sudo apache2ctl stop 
$ sudo apache2ctl start 
$ sudo apache2ctl restart 

You should now see Apache's default web page with the It Works! message.

PHP is a server-side scripting language and stands for PHP Hypertext Processor. Magento is implemented on PHP5 and Zend Framework, and we would need to install PHP and some additional libraries in order to run it.

Let's use apt-get again and run the following commands in order to get PHP5 and all the necessary libraries installed:

$ sudo apt-get install php5 php5-curl php5-gd php5-imagick php5-imap php5-mcrypt php5-mysql -y
$ sudo apt-get install php-pear php5-memcache -y
$ sudo apt-get install libapache2-mod-php5 -y

The first command installed not only PHP5, but it also installed additional packages required by Magento in order to connect with our database and manipulate images.

The second command will install PEAR, a PHP package manager, and a PHP memcached adapter.

The third command installs and sets up the PHP5 module for Apache.

We can finally test that our PHP installation is working by running the following command:

$ php -v

MySQL is a popular choice of database for many web applications, and Magento is no exception. We will need to install and set up MySQL as part of the development stack:

$ sudo apt-get install mysql-server mysql-client -y

During the installation, we will be asked to enter a root password; use magento2015. Once the installation has finished, we should have a MySQL service instance running in the background. We can test it by trying to connect to the MySQL server:

$ sudo mysql -uroot -pmagento2015

If everything is installed correctly, we should see the following mysql server prompt:

mysql>

At this point, we have a fully functional LAMP environment that can be used not only to develop and work on Magento websites, but also for any other kind of PHP development.

At this point, we have a basic LAMP setup up and running. However, to work with Magento, we would need to perform some configuration changes and additional setup.

The first thing that we will need to do is create a location to store our development sites files, so we will run the following commands:

$ sudo mkdir -p /srv/www/magento_dev/public_html/
$ sudo mkdir /srv/www/magento_dev/logs/
$ sudo mkdir /srv/www/magento_dev/ssl/

This will create the necessary folder structure for our first Magento site. Now, we need to check out the latest version of Magento. We can quickly get the files using SVN.

We would need to install SVN first on our server with the following command:

$ sudo apt-get install subversion -y

Once the installer has finished, open the magento_dev directory and run the svn command to get the latest version files:

$ cd /srv/www/magento_dev 
$ sudo svn export --force http://svn.magentocommerce.com/source/branches/1.9 public_html/

We will also need to fix some of the permissions on our new Magento copy:

$ sudo chown -R www-data:www-data public_html/
$ sudo chmod -R 755 public_html/var/ 
$ sudo chmod -R 755 public_html/media/ 
$ sudo chmod -R 755 public_html/app/etc/

Next, we need to create a new database for our Magento installation. Let's open our mysql shell:

$ sudo mysql -uroot -pmagento2015

Once in the mysql shell, we can use the create command, which should be followed by the type of entity (database or table) we want to create and the database name in order to create a new database:

mysql> create database magento_dev;

Although we could use the root credentials to access our development database, this is not a recommended practice to follow because it could compromise not only a single site, but also full database server. MySQL accounts are restricted based on privileges we want, in order to create a new set of credentials that has privileges limited to only our working database:

mysql> GRANT ALL PRIVILEGES ON magento_dev.* TO 'mage'@'localhost' IDENTIFIED BY 'dev2015$#';

Now, we need to properly set up Apache2 and enable some additional modules; fortunately, this version of Apache comes with a set of useful commands:

Magento uses the mod_rewrite module to generate URLs. The mod_rewrite module uses a rule-based rewriting engine to rewrite request URLs on the fly.

We can enable mod_rewrite with the a2enmod command:

$ sudo a2enmod rewrite

The next step will require that we create a new virtual host file under the site-available directory:

$ sudo nano /etc/apache2/sites-available/magento.localhost.com

The nano command will open a shell text editor, where we can set up the configuration for our virtual domain:

<VirtualHost *:80>
   ServerAdmin [email protected]
   ServerName magento.localhost.com
   DocumentRoot /srv/www/magento_dev/public_html

   <Directory /srv/www/magento_dev/public_html/>
      Options Indexes FollowSymlinks MultiViews
      AllowOverride All
      Order allow,deny
      allow from all
   </Directory>
   ErrorLog /srv/www/magento_dev/logs/error.log
   LogLevel warn
</VirtualHost>

To save the new virtual host file, press Ctrl + O and then press Ctrl + X. The virtual host file will tell Apache where it can find the site files and what permissions are to be given to it. In order for the new configuration changes to take effect, we need to enable the new site and restart Apache. We can use the following commands to do this:

$ sudo a2ensite magento.localhost.com
$ sudo apache2ctl restart

We are nearly ready to install Magento. We just need to set up a local mapping into our host system host file, using the following for Windows and Unix respectively:

Using Windows, we can do the following:

Using Unix/Linux/OS X, we can do the following:

We now can install Magento by opening http://magento.localhost.com in our browser. Toward the end, we should see the installer wizard. Follow the steps as indicated by the wizard, and you are set to go!
