Provisioning Vagrant CentOS Hosts

Overview

Process

Install Vagrant and VirtualBox Vagrant Download https://www.vagrantup.com/downloads.html

Virtual Box Download https://www.virtualbox.org/wiki/Downloads

Download the Oracle Instant Client RPMS. Store them in ~/Vagrant/packages.

These are available at http://www.oracle.com/technetwork/topics/linuxx86-64soft-092277.html Keep them once you've gone to the trouble to get them downloaded.

Create a new directory to hold your Vagrant host, and init Vagrant there.

mkdir -p ~/Vagrant/web;
cd ~/Vagrant/web;
vagrant init;

Modify the new Vagrantfile file. This Vagrant file will create a new virtual machine named 'web' that is based on the Chef CentOS image. This is a very bare-bones image with hardly any software installed. This is a good thing, as we'll be tailoring out Vagrant host to just what we want/need.

VAGRANTFILE_API_VERSION = "2"

Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|

  config.vm.define "web" do |web|
    # Use the Chef CentOS base image
    web.vm.box = "chef/centos-6.5"

    # Forward the Vagrant Host port 80 to port 5150 on your workstation. 
    web.vm.network "forwarded_port", guest: 80, host: 5150

    # Set up a private IP in the Vagrant Environment. Important for Multi-Host Vagrant deployments.
    web.vm.network "private_network", ip: "192.168.10.10"

    # Define the provision file.
    web.vm.provision :shell, :path => "web-bootstrap.sh"

    # Define a folder to map for locally hosted RPM files.
    # This is where we'll get the Oracle Instant Client files from.
    web.vm.synced_folder "~/Vagrant/packages", "/opt/packages"

    # Define a location for your local checkout of your webapp.
    web.vm.synced_folder "~/Source/webapp", "/local/www/webapp"
  end
end

Next, create and edit the web-bootstrap.sh file. This is a file that is executed to provison a new Vagrant host.

# DESCRIPTION =======================================================
# Bootstrap file for Logstash Vagrant host.
# Sets up Apache/PHP environment from scratch

Once these files are created, issue a vagrant up command to pull down the Chef image and start the provisioning process. When the process is done you can SSH to your Vagrant host with vagrant ssh. The host will expose the WebServer on port 5150, so point your browser at http://localhost:5150.

You can mount directories from your local file system into the Vagrant host by modifying the Vagrantfile.
