VagrantBlog.md

STEP 1 download linux 64bit vagrant from https://www.vagrantup.com/downloads.html

STEP 2.

sudo dpkg -i vagrant_1.7.1_x86_64.deb

STEP 3. init a project

mkdir programmer-mattress

vagrant init
/opt/vagrant/bin/../embedded/gems/gems/vagrant-1.7.1/lib/vagrant/pre-rubygems.rb:31: warning: Insecure world writable dir /usr/local/jdk1.7.0_05/bin in PATH, mode 040777
/opt/vagrant/embedded/gems/gems/bundler-1.7.9/lib/bundler/runtime.rb:222: warning: Insecure world writable dir /usr/local/jdk1.7.0_05/bin in PATH, mode 040777
A `Vagrantfile` has been placed in this directory. You are now
ready to `vagrant up` your first virtual environment! Please read
the comments in the Vagrantfile as well as documentation on
`vagrantup.com` for more information on using Vagrant.

STEP 4. add box to Vagrant

vagrant box add hashicorp/precise64

/opt/vagrant/bin/../embedded/gems/gems/vagrant-1.7.1/lib/vagrant/pre-rubygems.rb:31: warning: Insecure world writable dir /usr/local/jdk1.7.0_05/bin in PATH, mode 040777
/opt/vagrant/embedded/gems/gems/bundler-1.7.9/lib/bundler/runtime.rb:222: warning: Insecure world writable dir /usr/local/jdk1.7.0_05/bin in PATH, mode 040777
==> box: Loading metadata for box 'hashicorp/precise64'
    box: URL: https://atlas.hashicorp.com/hashicorp/precise64
This box can work with multiple providers! The providers that it
can work with are listed below. Please review the list and choose
the provider you will be working with.

1) hyperv
2) virtualbox
3) vmware_fusion

Enter your choice: 2
==> box: Adding box 'hashicorp/precise64' (v1.1.0) for provider: virtualbox
    box: Downloading: https://atlas.hashicorp.com/hashicorp/boxes/precise64/versions/1.1.0/providers/virtualbox.box
==> box: Successfully added box 'hashicorp/precise64' (v1.1.0) for 'virtualbox'!

note : vagrant init centos/7 in windows 7 is not working, maybe because of private network access/ proxy

to setup the box manually

wget https://atlas.hashicorp.com/ubuntu/boxes/trusty64/versions/14.04/providers/virtualbox.box
vagrant box add trusty-box ~/Downloads/trusty-server-cloudimg-amd64-vagrant-disk1.box
vagrant init trusty-box
vagrant up

STEP 5. use the added box

Vagrant.configure("2") do |config|
  config.vm.box = "hashicorp/precise64"
end

## also turn on ui
  config.vm.provider "virtualbox" do |vb|
  #   # Display the VirtualBox GUI when booting the machine
      vb.gui = true
  #
  #   # Customize the amount of memory on the VM:
  #   vb.memory = "1024"
  end

STEP 6. boot vagrant environment (PROVISION)

vagrant up
vagrant reload --provision

STEP 7. destroy the vagrant machine

vagrant destroy
