Roles that need to reload or restart Apache after writing configuration
files do not necessarily need to depend on the _apache_ role, but may
assume Apache is deployed in some other way. To support this, I have
factored out the handlers from the _apache_ role into an _apache-base_
role, which such roles can list as a dependency.
The *apache* role installs and configures the Apache HTTPD server and
its *mod_ssl* module. It currently only works on Fedora/RHEL-based
distributions.
