Configure Ubuntu and CentOS Webserver using Puppet

As I’m playing with the EC2 Puppet setup, here’s my simple web server in CentOS and Ubuntu puppet recipe. (need to edit more the Ubuntu installed packages ex. add php_mysql etc)

Tested in CentOS 5.0 and Ubuntu 8.04 AMI by Eric Hammond found at http://alestic.com.

class apache {
    # CentOS v.5 only
    case  $operatingsystem {
     "CentOS":  {
        $wantedpackages = [ "httpd","php","php-mysql","php-mcrypt","php-mhash","php-mbstring" ]
        package { $wantedpackages:
                  ensure => installed
        }
        service { "httpd":
                ensure => running,
                hasstatus => true,
                hasrestart => true,
                require => Package["httpd"],
                restart => true;
        }
      } 

    "Debian": {
        # assume Debian base..
        $wantedpackages = [ "apache2" ]
        package { $wantedpackages:
                  ensure => installed
        }

        service { "apache2":
                hasstatus => true,
                hasrestart => true,
                ensure => running,
                require => Package["apache2"]
        }
    }
  } # end case
}

Obviously a web node will have the config:

node webA.sample.org {
   include apache
}

Running it on EC2, pass a user-data script to the AMI during launch. A script that will set the hostname, adds default puppet master for the current instance and installs the puppetd. The puppetd program will then connect to the puppet server, and get all it’s needed configurations.
