Implement puppet module to install php

[jeff1evesque]

We will implement a php puppet module, to install php 5.6.

[jeff1evesque]

Our simplified configure_php.pp definition:

# variables
$working_dir = '/home/provisioner'

## define $PATH for all execs
Exec {path => ['/usr/bin/', '/usr/sbin/']}

## update yum using the added EPEL repository
class update_yum {
    exec { 'update-yum':
        command => 'yum -y update',
        timeout => 750,
    }
}

## install php
class install_php {
    ## set dependency
    require update_yum

    ## install php
    class { 'php': }
}

## constructor
class constructor {
    ## set dependency
    contain update_yum
    contain install_php
}
include constructor

generates the following traceback:

...
==> default: Running provisioner: puppet...
==> default: Running Puppet with environment development...
==> default: Error: Evaluation Error: Unknown function: 'params_lookup'. at /tmp
/vagrant-puppet/modules-3caf511b1ed192516806c35da44e64ef/php/manifests/init.pp:1
52:26 on node drupal-demonstration.com
The SSH command responded with a non-zero exit status. Vagrant
assumes that this means the command failed. The output for this command
should be in the log above. Please read the output to determine what
went wrong.

So, we attempt to reduce the debug time, by implementing the same test, within the terminal console:

[provisioner@drupal-demonstration ~]$ cd ~
[provisioner@drupal-demonstration ~]$ ls
[provisioner@drupal-demonstration ~]$ puppet module install example42-php

Specifically, we used the following definition for install_php.pp:

## install php
class install_php {
    ## install php
    class { 'php': }
}
contain install_php

We've created a corresponding issue, within the example42/puppet-php repository.

After php configurations have been made, we need to restart our httpd server.
