the recently added feature to support galera by allowing independent
creation of the root@localhost user in the DB and the /root/.my.cnf
file contains a bug.
specifically the .my.cnf file resource still requires the root@localhost
resource, even when it is not available.
this fixes the issue by making the dependency conditional.
This allows the galera module and others to write ${::root_home}/.my.cnf
independently from create the mysql user. This is useful for cluster
setups where you want to create ${::root_home}/.my.cnf on every node
but create the user only once.
This turned out to be a fairly bad idea. It begun as a way to try
and mirror what happens in the postgresql module for consistency
but instead made things complex.
I've changed it to have the override_options in mysql::server which
leads much more naturally out of the design and shape of MySQL.
This work adds a new mysql::globals class which contains a hash used to
build my.cnf from. It's used to share this data across multiple classes
so that the client and server can share this data.
End users can modify content in my.cnf by including mysql::globals and
passing in override_options as a hash that looks like:
override_options = { 'mysqld' => { 'max_connections' => '120' } }
This completely replaces the mess of parameters that existed in the main
mysql class before.
Completely refactor mysql::server and rework the API. This changes
ordering, changes from execs{} to mysql_user for the root password,
removes some functionality (like the etc_root_password), and generally
makes some tough decisions about how mysql::server should be built.
This initial round of work focuses on adding the concept of
mysql::globals to the module. This is a shared place to provide all the
data the module needs, and then clients, servers, and providers can all
rely on this information to set things up.
This is being primarily used at first to allow a default_options hash
that contains all the previous parameters and takes a overrides_options
that allows you to then further customize any of the options in my.cnf.
