This also likely affects Tumbleweed, Leap 42.2 and SLE 12 SP2 because all of them share the same service file. For reference the upstream service file recommendation is this: https://github.com/rabbitmq/rabbitmq-server/blob/90a1e737dec654dacb284c8245c163d846070b34/docs/rabbitmq-server.service.example but we can't use it because our erlang-epmd epmd.socket/service always run on 127.0.0.1. The upstream file uses a epmd@ template to make epmd@ listen to all addresses. Previously, rabbitmq-server could only run on 127.0.0.1. The current situation is not ideal, but it currently allows you to run rabbitmq-server on whatever IP you want. So if rabbitmq-server needs fixing, it's best to fix epmd at the same time. yes, rabbitmq requires epmd listen on any ip address. the problem is not happening any more on 42.2, feel free to close the ticket (In reply to Theo Chatzimichos from comment #5) > the problem is not happening any more on 42.2, feel free to close the ticket Slightly late (sorry just started using 42.2 for on the rabbitmq-server host) but I am still facing the same issue on 42.2 mainly because the socket still listens on 127.0.0.1 https://build.opensuse.org/package/view_file/devel:languages:erlang:Factory/erlang/epmd.socket?expand=1 I don't see where upstream defaults to localhost. Marcus where is that? I still see the recommended service file to be https://github.com/rabbitmq/rabbitmq-server/blob/1b0096a925ba56af16d4776713a5c8e9593c587a/docs/rabbitmq-server.service.example why can't we have the same? because it is much easier to do the stuff shown in our README.SUSE https://build.opensuse.org/package/view_file/devel:languages:erlang:Factory/erlang/README.SUSE?expand=1 OK talked to Marcus. I can live with the proposed solution. Seems like Dirk already has a workaround for openstack. I will also apply what Marcus suggested. Therefore I am closing this bug as WONTFIX |
The following issue affects the currently latest maintenance update for Leap 42.1 for rabbitmq-server, 3.5.1-4.1. It works fine with 3.5.1-2.7. When starting epmd via service, rabbitmq-server fails to start. It works if we don't start epmd from the service, but instead let rabbitmq start it. A few command outputs below: ## working scenario odb:~ # ps aux | grep epmd | grep -v grep odb:~ # rcrabbitmq-server start odb:~ # rcrabbitmq-server status rabbitmq-server.service - RabbitMQ broker Loaded: loaded (/usr/lib/systemd/system/rabbitmq-server.service; enabled) Active: active (running) since Wed 2016-10-05 13:02:44 UTC; 2s ago Process: 5615 ExecStop=/usr/sbin/rabbitmqctl stop (code=exited, status=0/SUCCESS) Main PID: 5750 (epmd) Status: "Exited."
