RabbitMQ does not start

Follow these steps to determine why the RabbitMQ service does not start.
  1. Verify RabbitMQ is NOT already running by typing
    sm_service show
    .
  2. Verify the
    Erlang
    process is NOT running by typing
    ps -ef | grep erl
    .
  3. If the Erlang process is running, stop it before restarting RabbitMQ.
    The Erlang process may be running from a prior installation, or was started outside the
    sm_service
    mechanism.
  4. Verify the
    qpidd
    process is NOT running by typing
    ps -ef | grep qpidd
    .
  5. If the
    qpidd
    process is running, stop it before restarting the RabbitMQ service.
    The
    qpidd
    process runs on some Linux distributions and can conflict with RabbitMQ by using the same port.
  6. Check that no other RabbitMQ installation exists by typing
    ps -ef | grep rabbit
    .
