Usage

Example

This is a simple example to configure a percona server.

Using the percona XtraDB module

class { 'percona':
    root_password => 'dummy_password',
    wsrep_cluster_address => 'gcomm://192.168.0.1:4010,192.168.0.2:4010',
    wsrep_cluster_name => 'mycluster'
}

Please note that in case you already have other DB machines in the cluster you will need to use the same value of innodb_log_file_size for all the components of the cluster.
