##Overview
This module manages RabbitMQ (www.rabbitmq.com)
##Module Description The rabbitmq module sets up rabbitmq and has a number of providers to manage everything from vhosts to exchanges after setup.
This module has been tested against 2.7.1 and is known to not support all features against earlier versions.
##Setup
###What rabbitmq affects
- rabbitmq repository files.
- rabbitmq package.
- rabbitmq configuration file.
- rabbitmq service.
###Beginning with rabbitmq
include '::rabbitmq'
##Usage
All options and configuration can be done through interacting with the parameters on the main rabbitmq class. These are documented below.
##rabbitmq class
To begin with the rabbitmq class controls the installation of rabbitmq. In here you can control many parameters relating to the package and service, such as disabling puppet support of the service:
class { '::rabbitmq':
service_manage => false,
port => '5672',
delete_guest_user => true,
}
Environment Variables
To use RabbitMQ Environment Variables, use the parameters environment_variables
e.g.:
class { 'rabbitmq':
port => '5672',
environment_variables => {
'RABBITMQ_NODENAME' => 'node01',
'RABBITMQ_SERVICENAME' => 'RabbitMQ'
}
}
Variables Configurable in rabbitmq.config
To change RabbitMQ Config Variables in rabbitmq.config, use the parameters config_variables
e.g.:
class { 'rabbitmq':
port => '5672',
config_variables => {
'hipe_compile' => true,
'frame_max' => 131072,
'log_levels' => "[{connection, info}]"
}
}
To change Erlang Kernel Config Variables in rabbitmq.config, use the parameters
config_kernel_variables
e.g.:
class { 'rabbitmq':
port => '5672',
config_kernel_variables => {
'inet_dist_listen_min' => 9100,
'inet_dist_listen_max' => 9105,
}
}
Clustering
To use RabbitMQ clustering facilities, use the rabbitmq parameters
config_cluster
, cluster_nodes
, and cluster_node_type
, e.g.:
class { 'rabbitmq':
config_cluster => true,
cluster_nodes => ['rabbit1', 'rabbit2'],
cluster_node_type => 'ram',
}

rabbitmq_vhost { 'myhost':
ensure => present,
}
rabbitmq_exchange
rabbitmq_exchange { 'myexchange@myhost':
user => 'dan',

##Limitations
This module has been built on and tested against Puppet 2.7 and higher.
The module has been tested on:
- RedHat Enterprise Linux 5/6
- Debian 6/7
- CentOS 5/6
- Ubuntu 12.04
Testing on other platforms has been light and cannot be guaranteed.
Module dependencies
To have a suitable erlang version installed on RedHat and Debian systems, you have to install another puppet module from http://forge.puppetlabs.com/garethr/erlang with:
puppet module install garethr-erlang
This module handles the packages for erlang. To use the module, add the following snippet to your site.pp or an appropriate profile class:
For RedHat systems:
include 'erlang'
class { 'erlang': epel_enable => true}
For Debian systems:
include 'erlang'
package { 'erlang-base':
ensure => 'latest',
}
##Development
Puppet Labs modules on the Puppet Forge are open projects, and community contributions are essential for keeping them great. We can’t access the huge number of platforms and myriad of hardware, software, and deployment configurations that Puppet is intended to serve.
We want to keep it as easy as possible to contribute changes so that our modules work in your environment. There are a few guidelines that we need contributors to follow so that we can have a chance of keeping on top of things.
You can read the complete module contribution guide on the Puppet Labs wiki.
