Public bug reported: The bug is actually located in erlang itself. epmd fails to bind to any IPv4 address if instructed to do so
[Impact] Users of RabbitMQ in IPv4 environments are unable to start rabbitmq unless the environment variable ERL_EPMD_ADDRESS is unset. In case of disabled IPv6 support there is no valid setting for ERL_EPMD_ADDRESS as * IPv4 addresses will be rejected as syntacitcally invalid * IPv6 addresses will fail to bind [Test Case] service rabbitmq-server stop && killall epmd ERL_EPMD_ADDRESS="127.0.0.1" epmd epmd: Thu Sep 25 21:00:16 2014: cannot parse IP address "127.0.0.1" same could be acieved with the epmd's -address option In case IPv6 support is disabled: ERL_EPMD_ADDRESS="::1" epmd epmd: Thu Sep 25 21:01:40 2014: failed to bind socket: Cannot assign requested address -- rabbitmq case: cat rabbitmq-env.conf export RABBITMQ_NODENAME=rabbit@localhost export RABBITMQ_NODE_IP_ADDRESS=127.0.0.1 export ERL_EPMD_ADDRESS=127.0.0.1 service rabbitmq-server start * Starting message broker rabbitmq-server * FAILED - check /var/log/rabbitmq/startup_\{log, _err\} [fail] Commenting/removing the "export ERL_EPMD_ADDRESS=127.0.0.1" line resolves the issue [Possible cause] In this bug: https://bugs.launchpad.net/ubuntu/+source/rabbitmq-server/+bug/1312507?comments=all The issue was fixed using -DEPMD6" in CPPFLAGS (https://bugs.launchpad.net/ubuntu/+source/rabbitmq- server/+bug/1312507/comments/5) which perhaps (I speculate only) activates some of the erlang's IPV6_V6ONLY definitions.
