Ajout d'une machine:¶

Sur le client:

$ apt-get install puppet

dans /etc/default/puppet mettre:

START=yes

et dans /etc/puppet/puppet.conf ajouter:

[agent]
server=puppet.tetaneutral.net

Ensuite ajouter la machine dans le puppet master, MOUAHAHA:
Sur le client:

$ puppet agent --test
warning: peer certificate won't be verified in this SSL session
warning: peer certificate won't be verified in this SSL session
warning: peer certificate won't be verified in this SSL session
Exiting; no certificate found and waitforcert is disabled

Sur le serveur:

$ puppetca --list
www.tetaneutral.net

$ puppetca  --sign --all
notice: Signed certificate request for www.tetaneutral.net
notice: Removing file Puppet::SSL::CertificateRequest www.tetaneutral.net at '/var/lib/puppet/ssl/ca/requests/www.tetaneutral.net.pem'

Sur le client:

$ puppet agent --test
warning: peer certificate won't be verified in this SSL session
info: Caching certificate for www.tetaneutral.net

Sur le serveur, on associe les modules au client:

$ cat manifests/nodes.pp

node basenode {
    include backup
    include motd
}

node 'www.tetaneutral.net' inherits basenode {
}

cd /etc/puppet/modules
mkdir -p  motd/{files,lib,manifests,templates,tests}
$ cat motd/manifests/init.pp
class motd {
        file {'motd':
                ensure  => file,
                path    => '/etc/motd.tail',
                mode    => 0644,
                content => "Bienvenue sur ${::hostname}, machine de l'infrastructure ${::domain}\n\nCette machine est geree par puppet toutes modifications effectuee est suceptible d'etre perdu." 
        }
}

Ajout du module à la liste des modules disponibles¶

import "backup" 
import "motd" 

Utilisation du module pour une node¶

    include backup
    include motd
}

node 'www.tetaneutral.net' inherits basenode {

}
