This kind of infrastructure was deployed under a Linux based operating system, specifically ubuntu 14.04.

Required Software:

• Chef Solo
• VirtualBox

In the sections below, instructions for executing the provisioning infrastructure are presented:

Clone the repository

git clone https://github.com/andresort28/vagrant-apache-haproxy-postgresql.git

Download CentOS

Due to each virtual machine has an operating system CentOS 6, you need to download a .box containing a clean CentOS 6 distribution from the following link:

Install a BOX in Vagrant

Add the .box with the name centos6

vagrant box add centos6 /.../centos6.box

Edit settings

Go to Vagrantfile an edit the name of the box you added to vagrant

server.vm.box = "centos6"
...
node1.vm.box = "centos6"
...
node2.vm.box = "centos6"
...
db.vm.box = "centos6"

Deploy

Open a terminal, go to the directory where you cloned the repository, and deploy the infrastructure

vagrant up

Verify

Open a browser and type 192.168.56.101:81 to see the load balancing, and type 192.168.56.101:81/select.php to view the queries to the database according to the web server
