Debian only.
The problem here is that the first time the galera is started it must be
done with some specific option, ie "--wsrep-new-cluster". Then it
shouldn't be used anymore. This has to be used only on one node or else
all nodes become master.
To achieve this behaviour a specific mysql init script is installed:
mysql-bootstrap.
This script check if the galera has started and, if it's not the case,
it adds wsrep-new-cluster to the command line.
Then in puppet I change the service name for mysql to mysql-bootstrap on
one node.
The port to RHEL could take the same road. The only requirement is
that:
$ strings `which mysqld` | grep wsrep-new-cluster
be true.
I don't add the close 11 to it as the rhel support should come with it I
think.
