Hiera error-could not initialize global default settings

edit

Greetings good people,

I'm very new to puppet who literally have only 3 days of experience. I have been following this great course "Puppet Fundamentals for System Administrators by "Pluralsight" and trying out everything exactly what the instructor say whcih worked perfectly so far but unfortunately I cant seem to get my hiera configurations right. :( I get the below error when I run "puppet --verbose --no-daemonize --onetime" from corresponding agents.

[root@box2 ssl]# puppet --verbose no-daemonize --onetime -Error: Could not initialize global default settings: Error parsing arguments Wrapped exception: invalid argument syntax: '--' [root@box2 ssl]

What I'm trying to do here is to deploy a fresh "mediawiki" site on 2 clients via puppet. Note that in puppet master I have successfully installed passenger and apache. Also note that the whole deployment of mediawiki on 2 clients worked flawlessly when hiera was not used. Following is my setup.

• puppetmaster - box1.mylab.jazz
• agent 1 - box2.mylab.jazz
• agent 2 - box3.mylab.jazz

a) Below is an extract from "/etc/puppet/puppet.conf" file.

 dns_alt_names = box1,box1.mylab.jazz

[master]
    environmentpath = $confdir/environments
    basemodulepath = $confdir/modules:/opt/puppet/share/modules

[agent]
       classfile = $vardir/classes.txt

       localconfig = $vardir/localconfig

b) Below is an the "/etc/puppet/environments/production/manifests/nodes.pp"

node 'box2.mylab.jazz' {

  hiera_include('classes')

}

node 'box3.mylab.jazz' {

  hiera_include('classes')

}

class linux {

  file { '/info.txt':
    ensure  => 'present',
    content => inline_template("created by puppet at <%= Time.now %>\n"),
  }

  $admintools = ['git', 'nano', 'screen']

  package { $admintools:
    ensure => 'installed',
  }

  service { 'ntpd':
    ensure => 'running',
    enable => true,
  }

}

c) below is the manifest of mediawiki module on "/etc/puppet/environments/production/modules/mediawiki/manifests/init.pp" NOTES: The variables mentioned (prefixed with "$wiki") on the very top of this file are meant for a php file that is required by mediawiki on all agents.

 class mediawiki {

  $wikimetanamespace = hiera('mediawiki::wikimetanamespace')
  $wikisitename      = hiera('mediawiki::wikisitename')
  $wikiserver        = hiera('mediawiki::wikiserver')
  $wikidbserver      = hiera('mediawiki::wikidbserver')
  $wikidbname        = hiera('mediawiki::wikidbname')
  $wikidbuser        = hiera('mediawiki::wikidbuser')
  $wikidbpassword    = hiera('mediawiki::wikidbpassword')
  $wikiupgradekey    = hiera('mediawiki::wikiupgradekey')

  $phpmysql = $osfamily ? {
    'redhat'  => 'php-mysql',
    'debian'  => 'php5-mysql',
    'default' => 'php-mysql',
  }

  package { $phpmysql:
    ensure => 'present',
  }

  if $osfamily == 'redhat' {    ##running a condition. insatll phpxml only on redhat based
   package { 'php-xml':
     ensure => 'present',
   }
  }

  class { '::apache':
    docroot    => '/var/www/html',
    mpm_module => 'prefork',
    subscribe  => Package[$phpmysql], ##metaparameter. 2 things it does. if phpmysql package ever changes puppet will restart httpd. make sure myphp is installed before apache
  }

  class { '::apache::mod::php':} ##"::" is top scope which tells pup to look for apache class instead of our classes, modules. 

  class { '::mysql::server':
    root_password => 'redhat',
  }

  file { 'LocalSettings.php':
    path    => '/var/www/html/LocalSettings.php',
    ensure  => 'file',
    content => template('mediawiki/LocalSettings.erb'),
  }

}

c). hiera config file "/etc/puppet/hiera.yaml"

:backends:
  - yaml
:yaml:
  :datadir:
:hierarchy:
  - "%{clientcert}"
  - boxdefault
:logger: console

d). hiera resource files under "/var/lib/hiera/"

>   [root@box1 hiera]# ls  -ltr
> /var/lib/hiera/
