- name: Fail if installation method is not 'distro'
  fail:
    msg: "The only supported rabbitmq_install_method for RedHat is 'distro'."
  when: rabbitmq_install_method != 'distro'

# NOTE(hwoarang) on RedHat, rabbitmq-server depends on epmd.service which
# depends on epmd.socket which runs on localhost. It is just easier to let
# the rabbitmq-server launch epmd directly since we are inside a container.
- name: Add rabbitmq-server systemd service (RedHat)
  template:
    src: "rabbitmq-server.service.j2"
    dest: "/etc/systemd/system/rabbitmq-server.service"
  register: rabbitmq_server_service_added
  # NOTE(hwoarang) Normally, this task should only be executed when
  # rabbitmq_install_method == 'distro'. However, the upstream package
  # does not contain a systemd file and as such we need to provide one.
  # This should be reverted once https://github.com/rabbitmq/rabbitmq-server-release/pull/31
  # is merged and new builds of rabbitmq-server are available.
