I'm trying to ensure MySQL-server is installed on a node which I've placed in a yum repo, however at the same time, my Red Hat repo has the mysql-server package available. It appears the puppet yum package provider is not case-sensitive so if I ensure that mysql-server is absent and ensure MySQL-server is installed, my MySQL-server package gets installed and removed every other run.

I could take that approach, however I was hoping to avoid it. You see, on my default server installation I want to have the mysql-server package from Red Hat. It's only in certain cases where I need to override this with a newer package. If I were to take your approach I would have to manipulate the yum.conf for these class of systems to prevent it from getting the Red Hat package. I was hoping to avoid this as I'm already managing the yum.conf in another module. This would require special handling just for this small ... (more)

This is actually something you need to fix in your package manager I think.

In yum.conf for every repository you have a [repo] section. To every one of those section you can add an exclude entry like this exclude=mysql*.

Or if you're using yum/conf.d find all the repositories that provide the mysql package and add the exclude to those you want to avoid.

Once you got that sorted, remove the package you want gone and on the next run let Puppet handle it.

You can also have a look at the following plugins for YUM ... (more)

You've got a few options.

exclude as needed. I'd use hiera_array and collect an excludes needed and write them out as needed in your yum module. Pros: adds useful functionality to your Puppet code base Cons: Need to setup Hiera and plan how you'd use this data.

hieradata/fqdn_of_special_db_server.yaml

yum_base_excludes: ['mysql-server','mysql-client','mysql-libs','mysql-devel']

modules/yum/manifests/init.pp

$base_excludes = hiera_array('yum_base_excludes')

Where you go from here depends on how you set repo files.
Set specific version, ensure => '5.5.17'. I assume the versions would be different between Redhat and Mysql provided packages. Set to ...
