Introduction to Chef Chef

To deploy PHP and MySQL I will use predefined modules available at forge.puppet.com. You can create your own modules as well.

Step 1: In Puppet Master install MySQL and PHP modules.

Execute this: 

1) puppet module install puppetlabs-mysql –version 3.10.0

This MySQL module installs, configures, and manages the MySQL service. This module manages both the installation and configuration of MySQL, as well as extending Puppet to allow management of MySQL resources, such as databases, users, and grants.

2) puppet module install mayflower-php –version 4.0.0-beta1

This module is used for managing PHP, in particular php-fpm. PHP-FPM (FastCGI Process Manager) is an alternative PHP FastCGI implementation with some additional features useful for sites of any size, especially busier sites.

Step 2: In Puppet Manifests include MySQL server and PHP.

Execute this: vi /etc/puppet/manifests/site.pp

You can use any other editor as well like vim, gedit etc. In this site.pp file add the following:

Save and quit.

Step 3: Puppet Slaves pulls its configuration from the Master periodically (after every 30 minutes). It will evaluate the main manifest and apply the module that specifies MySQL and PHP setup. If you want to try it out immediately, you need to run the following command on every Slave node:

Execute this: puppet agent -t

So MySQL and PHP is installed successfully on the Slave node.

Step 4: To check the version of MySQL and PHP installed: 

Execute this:

1) mysql -v

2) php -version

Congratulations! MySQl and PHP is up and running in your Puppet Slave. Here I have shown you only one Slave but imagine if there are hundreds of Slaves. In that scenario your work becomes so easy, Just specify the configurations in Puppet Master and Puppet Slaves will automatically evaluate the main manifest and apply the module that specifies MySQL and PHP setup.
