A nice little Vagrantfile that spins up a MySQL server and loads in the data from your .sql file sitting next to it.

Vagrantfile

# -*- mode: ruby -*-
# vi: set ft=ruby :

# This Vagrantfile (vagrantup.com) spins up a MySQL server with your data 
# already loaded. Many of the settings below are the same suggestions you get
# from `vagrant init`.
#
# Just be sure that (if you want data loaded) you have your .sql file sitting
# in the directory that will be shared to the guest. Usually this is the folder
# that your Vagrantfile is in. The database and user will have the same name as
# the .sql file, so name it something appropriate. It's probably best to stick
# to letters (and numbers ?) because I didn't do any crazy substitution rules.
#
# The mysql root user and the user with the same name as your file will be using
# 'pass' as their password. User 'vagrant'@'localhost' doesn't use a password,
# so you can just run `mysql` after you ssh into your VM and jump right in.
#
# Feel free to change the vm.box and vm.box_url, but I know it works with this
# one since it's already a LAMP server.
#
# Enjoy!

  # Every Vagrant virtual environment requires a box to build off of.

  # The url from where the 'config.vm.box' box will be fetched if it
  # doesn't already exist on the user's system.

  # Create a forwarded port mapping which allows access to a specific port
  # within the machine from a port on the host machine. In the example below,
  # accessing "localhost:8080" will access port 80 on the guest machine.
  config.vm.network :forwarded_port, guest: 80, host: 8080  

  # Make this VM reachable on the host network as well, so that other
  # VM's running other browsers can access our dev server.
  config.vm.network :private_network, ip: "192.168.33.10"

  # Create a public network, which generally matched to bridged network.
  # Bridged networks make the machine appear as another physical device on
  # your network.
  # config.vm.network :public_network

  # Make it so that network access from the vagrant guest is able to
  # use SSH private keys that are present on the host without copying
  # them into the VM.
  config.ssh.forward_agent = true

  # Share an additional folder to the guest VM. The first argument is
  # the path on the host to the actual folder. The second argument is
  # the path on the guest to mount the folder. And the optional third
  # argument is a set of non-required options.
  # config.vm.synced_folder "../data", "/vagrant_data"

  # Provider-specific configuration so you can fine-tune various
  # backing providers for Vagrant. These expose provider-specific options.
  # Example for VirtualBox:
  #
  # config.vm.provider :virtualbox do |vb|
  #   # Don't boot with headless mode
  #   vb.gui = true
  #
  #   # Use VBoxManage to customize the VM. For example to change memory:
  #   vb.customize ["modifyvm", :id, "--memory", "1024"]
  #
  #   # This setting makes it so that network access from inside the vagrant guest
  #   # is able to resolve DNS using the hosts VPN connection.
  #   # (The Discourse folks use this, so I just left it.)
  #   v.customize ["modifyvm", :id, "--natdnshostresolver1", "on"]
  # end
  #
  # View the documentation for the provider you're using for more
  # information on available options.
