You should change that script to use a custom directory name. If you are
running a database instance for each service, you should have a separate
my.cnf file for each service and also a separate "datadir" filesystem.
Cluster is able to manage mysql as a resource on its own without using any
external script.
I.e:
<mysql config_file="/datadir/my.cnf" listen_address="x.x.x.x"
name="mydatabase1" />

Hope that helps,
