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,
}

Or such as offline installation from intranet or local mirrors:

class { '::rabbitmq':
   key_content      => template('openstack/rabbit.pub.key'),
   package_gpg_key  => '/tmp/rabbit.pub.key',
}

And this one will use external package key source for any (apt/rpm) package provider:

class { '::rabbitmq':
   package_gpg_key  => 'http://www.some_site.some_domain/some_key.pub.key',
}

Environment Variables

To use RabbitMQ Environment Variables, use the parameters environment_variables e.g.:

class { 'rabbitmq':
  port              => '5672',
  environment_variables   => {
    'NODENAME'     => 'node01',
    '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,
  }
}

To change Management Plugin Config Variables in rabbitmq.config, use the parameters config_management_variables e.g.:

class { 'rabbitmq':
  config_management_variables  => {
    'rates_mode' => 'basic',
  }
}

Additional Variables Configurable in rabbitmq.config

To change Additional Config Variables in rabbitmq.config, use the parameter config_additional_variables e.g.:

class { 'rabbitmq':
  config_additional_variables => {
    'autocluster' => '[{consul_service, "rabbit"},{cluster_name, "rabbit"}]',
    'foo' => '[{bar, "baz"}]'
  }
}

This will result in the following config appended to the config file:

% Additional config
  {autocluster, [{consul_service, "rabbit"},{cluster_name, "rabbit"}]},
  {foo, [{bar, "baz"}]}

(This is required for the autocluster plugin

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',
  erlang_cookie            => 'A_SECRET_COOKIE_STRING',
  wipe_db_on_cookie_change => true,
}

rabbitmq_user

query all current users: $ puppet resource rabbitmq_user

rabbitmq_user { 'dan':
  admin    => true,
  password => 'bar',
}

Optional parameter tags will set further rabbitmq tags like monitoring, policymaker, etc. To set the administrator tag use admin-flag.

rabbitmq_user { 'dan':
  admin    => true,
  password => 'bar',
  tags     => ['monitoring', 'tag1'],
}

rabbitmq_vhost

query all current vhosts: $ puppet resource rabbitmq_vhost

rabbitmq_vhost { 'myvhost':
  ensure => present,
}

rabbitmq_exchange

rabbitmq_exchange { 'myexchange@myvhost':
  user     => 'dan',
  password => 'bar',
  type     => 'topic',
  ensure   => present,
  internal => false,
  auto_delete => false,
  durable => true,
  arguments => {
    hash-header => 'message-distribution-hash'
  }
}

  user        => 'dan',
  password    => 'bar',
  durable     => true,
  auto_delete => false,
  arguments   => {
    x-message-ttl => 123,
    x-dead-letter-exchange => 'other'
  },
  ensure      => present,
}

rabbitmq_binding

rabbitmq_binding { 'myexchange@myqueue@myvhost':
  user             => 'dan',
  password         => 'bar',
  destination_type => 'queue',
  routing_key      => '#',
  arguments        => {},
  ensure           => present,
}

rabbitmq_user_permissions

rabbitmq_user_permissions { 'dan@myvhost':
  configure_permission => '.*',
  read_permission      => '.*',
  write_permission     => '.*',
}

rabbitmq_policy

rabbitmq_policy { 'ha-all@myvhost':
  pattern    => '.*',
  priority   => 0,
  applyto    => 'all',
  definition => {
    'ha-mode'      => 'all',
    'ha-sync-mode' => 'automatic',
  },
}

  ensure => present,
}

rabbitmq_parameter

  rabbitmq_parameter { 'documentumShovel@/':
    component_name => '',
    value          => {
        'src-uri'    => 'amqp://',
        'src-queue'  => 'my-queue',
        'dest-uri'   => 'amqp://remote-server',
        'dest-queue' => 'another-queue',
    },
  }

    component_name => 'federation-upstream',
    value          => {
        'uri'    => 'amqp://myserver',
        'expires' => '360000',
    },
  }

rabbitmq_erlang_cookie

This is essentially a private type used by the rabbitmq::config class to manage the erlang cookie. It replaces the rabbitmq_erlang_cookie fact from earlier versions of this module. It manages the content of the cookie usually located at "${rabbitmq_home}/.erlang.cookie", which includes stopping the rabbitmq service and wiping out the database at "${rabbitmq_home}/mnesia" if the user agrees to it. We don't recommend using this type directly.

Limitations

This module has been built on and tested against Puppet 3.x.

The module has been tested on:

  • RedHat Enterprise Linux 5/6
  • Debian 6/7
  • CentOS 5/6
  • Ubuntu 12.04/14.04

Testing on other platforms has been light and cannot be guaranteed.

Apt module compatibility

While this module supports both 1.x and 2.x versions of the puppetlabs-apt module, it does not support puppetlabs-apt 2.0.0 or 2.0.1.

Module dependencies

If running CentOS/RHEL, and using the yum provider, ensure the epel repo is present.

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',
}

This module also depends on the excellent puppet/staging module on the Forge:

puppet module install puppet-staging

Downgrade Issues

Be advised that there were configuration file syntax and other changes made between RabbitMQ versions 2 and 3. In order to downgrade from 3 to 2 (not that this is a terribly good idea) you will need to manually remove all RabbitMQ configuration files (/etc/rabbitmq) and the mnesia directory (usually /var/lib/rabbitmq/mnesia). The latter action will delete any and all messages stored to disk.

Failure to do this will result in RabbitMQ failing to start with a cryptic error message about "init terminating in do_boot", containing "rabbit_upgrade,maybe_upgrade_mnesia".

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.
