You have a completely wrong idea of what class inheritance is for in
Puppet. Its appropriate uses are in fact very narrow. The natural and
idiomatic expression of what you describe is this:
class website {
include 'httpd'
include 'mysqld'
...
}
That approach would be better form even if class website needed only one
other class to be applied.
Note also that that does not in itself say anything about the *order* in
which resources are applied to clients; rather, it says that all nodes to
which the 'website' class is assigned also have the 'httpd' and 'mysqld'
classes assigned to them. If you need ordering relationships among these
then there are additional steps you can take.
You certainly do not need a define to express the concept you asked about,
although you can do it that way, too. Whether a defined type instance or a
class is more appropriate for your particular case would involve an
analysis of your use of the class, but the fact that you can do what you
want with a class at all is a strong argument for a class being the right
thing to use.
