Puppet users - Jul 2012 - Defining node types in modules

Hello,

This is the way we currently define nodes using modules/classes. Unsure if 
this is the best method but as dashboard does not do parameterized class 
variables seems the right way.

We apparent zen_ to everything thats making up our servers. I am having 
problems with the MySQL module as I need to include mysql:: several times 
to get the features - https://github.com/puppetlabs/puppetlabs-mysql

err: Could not retrieve catalog from remote server: Error 400 on SERVER: 
Duplicate declaration: Class[Mysql] is already declared; cannot redeclare 
at 
/etc/puppet/modules/zen_puppet01opslab/manifests/puppetdashboard_mysql.pp:2

I question if we are using the right approach with puppet and if this is 
the right way to define types of servers.

Module:  - zen_puppet01opslab

root@puppet01:/etc/puppet/modules/zen_puppet01opslab/manifests# cat init.pp 

class zen_puppet01opslab {
    class { ''zen_puppet01opslab::puppetdashboard'': }
    class { ''zen_puppet01opslab::puppetdashboard_mysql'': }
}

root@puppet01:/etc/puppet/modules/zen_puppet01opslab/manifests# cat 
puppetdashboard.pp 
class zen_puppet01opslab::puppetdashboard {
        class  { ''dashboard'':
        dashboard_ensure          => ''present'',
        dashboard_user            => ''puppet-dashboard'',
        dashboard_group           => ''puppet-dashboard'',
        dashboard_password        => ''XXXXX'',
        dashboard_db              => ''dashboard_prod'',
        dashboard_charset         => ''utf8'',
        dashboard_site            => $fqdn,
        dashboard_port            => ''8141'',
        mysql_root_pw             => ''XXXXXX'',
      #  passenger                 => true,
        }
}

root@puppet01:/etc/puppet/modules/zen_puppet01opslab/manifests# cat 
puppetdashboard_mysql.pp 
class zen_puppet01opslab::puppetdashboard_mysql {
    class  { ''mysql'': }
#        ''mysql::ruby'':
#        ''mysql::server'':
    mysql::ruby { ''bleh'': }
    mysql::server { ''bleh'':
        config_hash => { ''root_password'' =>
''secretmysqlpassword'' }
    }
}
