Classes and Definitions

• Classes are groups of resources.

• Definitions are similar to classes, but they can be instantiated multiple times with different arguments on the same node.

• class apache2 {

• define simple-vhost ( $admin = "webmaster", $aliases, $docroot) {

• file { "/etc/apache2/sites-available/$name":

• mode => "644",

• require => [ Package["apache2"], Service["apache2"] ],

• content => template("apache/vhost.conf"),

• } } }

• node debiantest {

• • include apache2
  • apache2::simple-vhost { "debian.example.com": docroot => "/var/www/debian"}
  • apache2::simple-vhost { "test.example.com": docroot => "/var/www/test"}

• }
