This is a good start to play around with the galera multi-master mysql synchronous replication (http://www.codership.com/products/mysql_galera)
HOWTO:
* play around (add a database and data, chaos-monkey nodes etc.)
WARNING
Change the mysql root password in production and limit access to galera cluster members!
TODO
* naming: master -> donor
* put a load balancer in front of the cluster
* make cluster "masterless"
nodes.pp
# nodes
$cluster_name = 'wsrep_galera_cluster'
node /mysql-db-01/ {
class { 'galera' :
cluster_name => $cluster_name
}
}
node /mysql-db-0([2-9])/ {
$master_ip = '172.18.67.254'
class { 'galera' :
cluster_name => $cluster_name,
master_ip => $master_ip
}
}
