- Configure any necessary settings
- Put your Puppet modules and manifests in place
- Configure a production-ready web server
- Configure load balancing and CA service routing if you’re using multiple masters
- Start the puppet master service
Agent
sudo apt-get install puppet
Puppet manifest

Déclaration de ressources
The format is always the same:
resource_type { 'resource_title':
ensure => present, # usually 'present' or 'absent'
attribute1 => 1234, # number
attribute2 => 'value', # string
attribute3 => ['red','blue'], # array
noop => false, # boolean
}
"resource_title" doit être unique. Si deux ressources porte le même nom, la deuxième de sera pas traitée. Il est possible de nommer une ressource "file" par le path entier du fichier.
Attributes (des ressources)

- Variables
Le nom: start with $ name must start with a lower case letter, and may contain lower case letters, numbers, and underscores.)
$myvar # valid $MyVar # invalid $my_var # valid $my-var # invalid $_myvar # invalid $my3numbers # valid $3numbers # invalid
La valeur:
Boolean $not_true = false
Integer $num_tokens = 115
String $my_name = 'Joe'
Array[Integer] $my_list = [1,4,7]
Array[String] [$first,$last] = ['Jo','Rhett']
Hash $key_pairs = {name => 'Joe', uid => 1001}

Class Declaration
A class declaration occurs when a class is called in a manifest. A class declaration tells Puppet to evaluate the code within the class. Class declarations come in two different flavors: normal and resource-like.
A normal class declaration occurs when the include keyword is used in Puppet code, like so:
include example_class
This will cause Puppet to evaluate the code in example_class.
A resource-like class declaration occurs when a class is declared like a resource, like so:
class { 'example_class': }
Using resource-like class declarations allows you to specify class parameters, which override the default values of class attributes. If you followed the prerequisite tutorial, you have already used a resource-like class declaration ("apache" class) when you used the PuppetLabs Apache module to install Apache on host2:
node 'host2' {
class { 'apache': } # use apache module
apache::vhost { 'example.com': # define vhost resource
port => '80',
docroot => '/var/www/html'
}
}
