###Chef-solo usage On a node that provides both a Management Server and a MySQL Server, use both the mgmd and mysqld recipes:

{ "run_list": ["recipe[ndb::install]", "recipe[ndb::mgmd]", "recipe[ndb::mysqld]" }

This will install and start both a ndb_mgmd and a mysqld daemon on both nodes.

On a node that will provide a data node, run: { "run_list": ["recipe[ndb::install]", "recipe[ndb::ndbd]" }

This will install a data node on the host, that is, an ndbd process.

You can override attributes in your node or role. For example, on an Ubuntu system: { "mysql": { "password": "secret" } }

###Karamel usage This cookbook is karamelized (www.karamel.io). You can launch a MySQL Cluster using the following yml file. It will create 5 VMs on EC2, and install ndb datanodes on 4 VMs, and a management server, a MySQL Server, and a Memcached server on 1 VM.
