Review of Puppet NTP

Posting an example which helps me remember what I learned about puppet a week ago; an NTP class which hasn't yet been converted into a module from Learning — Modules and Classes (Part One). I borrowed the HTML/CSS from puppetlabs.com.

      
    class ntp {
      case $operatingsystem {
        centos, redhat: { 
          $service_name = 'ntpd'
          $conf_file    = 'ntp.conf.el'
        }
        debian, ubuntu: { 
          $service_name = 'ntp'
          $conf_file    = 'ntp.conf.debian'
        }
      }
      
      package { 'ntp':
        ensure => installed,
      }
      
      service { 'ntp':
        name      => $service_name,
        ensure    => running,
        enable    => true,
        subscribe => File['ntp.conf'],
      }
      
      file { 'ntp.conf':
        path    => '/etc/ntp.conf',
        ensure  => file,
        require => Package['ntp'],
        source  => "/root/learning-manifests/${conf_file}",
      }
    }

Learning Puppet: Modules & Classes

I am having a good time leaning puppet and have finished up to Modules & Classes for today. One thing we need where I work is a way to insure that PHP is set up consistently and thias/php might do the trick. Checking it out...

[root@learn ~]# puppet module install thias-php
Preparing to install into /etc/puppetlabs/puppet/modules ...

USB to RS-232

Today I received my USB to Serial Converter for connecting my laptop to an RS-232 serial device. Cisco has a cheat sheet for using screen to connect to their gear.

Personal OpenStack via Crowbar

Crowbar was made to easily deploy OpenStack. Here are two 10 minute videos showing how to install Crowbar:

and then install OpenStack on top of it.

The narrator, Rob Hirscheld, does it all on one physical box using a couple of VMs.
