Description

This is a cookbook for managing RabbitMQ with Chef. It uses the default settings, but can also be configured via attributes.

Recipes

default

Installs rabbitmq-server from RabbitMQ.com's APT repository, your distro's version, or the DEB or RPM directly (there is no yum repo). Depending on your distribution, the provided version may be quite old so they are disabled by default. If you want to use the distro version, set the attribute ['rabbitmq']['use_distro_version'] to true.

Cluster recipe is now combined with default. Recipe will now auto-cluster. Set the :cluster attribute to true, :cluster_disk_nodes array of node@host strings that describe which you want to be disk nodes and then set an alphanumeric string for the :erlang_cookie.

To enable SSL turn :ssl to true and set the paths to your cacert, cert and key files.

Resources/Providers

There are 3 LWRPs for interacting with RabbitMQ.

user

Adds and deletes users, fairly simplistic permissions management.

• :add adds a user with a password
• :delete deletes a user
• :set_permissions sets the permissions for a user, vhost is optional
• :clear_permissions clears the permissions for a user

Examples

rabbitmq_user "guest" do
  action :delete
end

rabbitmq_user "nova" do
  password "sekret"
  action :add
end

rabbitmq_user "nova" do
  vhost "/nova"
  permissions "\".*\" \".*\" \".*\""
  action :set_permissions
end

vhost

Adds and deletes vhosts.

• :add adds a vhost
• :delete deletes a vhost

Example

rabbitmq_vhost "/nova" do
  action :add
end

plugin

Enables or disables a rabbitmq plugin.

• :enable enables a plugin
• :disable disables a plugin

Example

rabbitmq_plugin "rabbitmq_stomp" do
  action :enable
end

rabbitmq_plugin "rabbitmq_shovel" do
  action :disable
end

Limitations

For an already running cluster, these actions still require manual intervention:

• changing the :erlang_cookie
• turning :cluster from true to false

The rabbitmq::chef recipe was only used for the chef-server cookbook and has been moved to chef-server::rabbitmq.
