    To get started with MySQL Cluster, read MySQL Cluster Quick Start at
      http://dev.mysql.com/downloads/cluster/

    Default configuration files have been created inside:
      #{var}/mysql-cluster
    Note that in a production system there are other parameters
    that you would set to tune the configuration.

    Launchd plists templates to automatically load the various nodes can be copied from:
      #{plist_path('ndb_mgmd')}
      #{plist_path('ndbd')}
      #{plist_path('mysqld')}

    For a first cluster, you may start with a single MySQL Server (mysqld),
    a pair of Data Nodes (ndbd) and a single management node (ndb_mgmd):

      mysql_install_db --no-defaults --basedir=#{prefix} --datadir=#{var}/mysql-cluster/mysqld_data
      ndb_mgmd -f #{var}/mysql-cluster/conf/config.ini --initial --configdir=#{var}/mysql-cluster/conf/
      ndbd -c localhost:1186
      ndbd -c localhost:1186
      mkdir -p ~/Library/LaunchAgents
      cp #{plist_path('mysqld')} ~/Library/LaunchAgents/
      launchctl load -w ~/Library/LaunchAgents/#{plist_path('mysqld').basename}
      mysql -h 127.0.0.1 -P 5000 -u root -p
      (Leave the password empty and press Enter)
        create database clusterdb;
        use clusterdb;
        create table simples (id int not null primary key) engine=ndb;
        insert into simples values (1),(2),(3),(4);
        select * from simples;

    To shutdown everything:

      launchctl unload -w ~/Library/LaunchAgents/#{plist_path('mysqld').basename}
      ndb_mgm -e shutdown
    EOS
