Using Bitnami's Rubystack on VirtualBox Linux With Vagrant

| Comments

In my Software Engineering Projects class, we are going to do a RAILS-based project. Based on feedback from last year’s class, I am furnishing students with an almost configured RAILS system for development. The system is based on

Create the base machine

The Vagrantfile is configured to support networking from the host machine and to run a configuration script (script.sh) as part of the provisioning. There is a small bit of logic to avoid re-provisioning things each time the machine is brought up.

I make it by following roughly the following procedure:

  1. Install Virtualbox
  2. Install Vagrant
  3. Create a directory to place files add in
    • The bitnami linux installer file
    • Vagrantfile
    • script.sh
  4. Do an install: vagrant up
  5. SSH into the running host: vagrant ssh
  6. Use Linux as needed
  7. Exit back to the host OS: exit
  8. Shutdown the virtual machine (saving the contents): vagrant halt
  9. Package the machine post configuration with vagrant package default --output rails3r2e13.box

  10. Restart the machine and continue work: vagrant up

Install the base machine on student computer

OS X/Linux commands are given here, change the direction of the / (to \) for Windows.

  1. Install Virtualbox
  2. Install Vagrant
  3. Create a vms directory for your development use mkdir vms
  4. Create a machine1 directory mkdir vms/machine1 It will be accessible to both Linux and your operating system.
  5. cd vms/machine1
  6. vagrant init rails3r2e13.box url_to_image
  7. uncomment config.vm.network :private_network, ip: "192.168.33.10" in Vagrantfile
  8. vagrant up # first time will download the vm machine
  9. vagrant ssh # if this fails, you need to put SSH on the path

SSH for Windows

Windows does not include SSH by default. Two options are to 1) install Git locally and then use it’s SSH implementation and 2) install PuTTY.

Limitations

The file .bashrc has a line at the end of it that maps the rails commands onto the path along with library linkage as well. This messes up some local commands nano and others. One solution is to comment out the line and re-log into the VM.

Other vagrant commands

  • vagrant destroy eliminate the virtual machine so next time it will be rebuilt
  • vagrant reload combination of of halt then up
  • vagrant suspend pause machine copying state to disk, resume with `vagrant resule“
