Vagrant is a tool for building and managing virtual machine environments. Assuming you have already installed and  vagrant up your virtual environment. Execute the following instructions on your terminal console. Download symfony installer sudo curl -LsS https://symfony.com/installer -o /usr/local/bin/symfony sudo chmod a+x /usr/local/bin/symfony Create project directory symfony new my_project Then, you can: * Change your current directory to /vagrant/my_project * Configure your application in app/config/parameters.yml file. * Run your application: 1. Execute the php bin/console server:run command. 2.

Download VirtualBox and Vagrant Create a directory for your virtual environment mkdir vagrant_env1 cd vagrant_env1 Install your preferred box (Ubuntu 12.04 LTS 64-bit for this example): vagrant init hashicorp/precise64 or vagrant init vagrant box add hashicorp/precise64 You may check this HashiCorp's Atlas box catalog for more type of boxes. By the way, a "box" is a base image of an operating system. This enables you to quickly clone a virtual machine rather than starting from scratch, which would be a slow and tedious process. Installing may take some time, but after that, you can re-use this box when you want to create another virtual environment. Now run vagrant up: vagrant up To enter the virtual machine, simply SSH: vagrant ssh
