# PASTE YAML HERE, BETWEEN BACKTICKSWhat problem are you trying to solve?Rabbitmq fails to start when installed with homebrew. Manually running the rabbitmq-server fails with the above error. It looks like it cannot connect to epmd. What works is I manually ran epmd in a separate terminal and then rabbitmq-server will start. It looks like the issue is brew install does not start up epmd. Is it supposed to? I could not find any posts encountering this issue and wonder if I am doing something wrong. |

Can you point me where epmd is started? I looked in the ~/Library/LaunchAgents/homebrew.mxcl.rabbitmq.plist and only saw reference to the rabbitmq-server being started. I would think if I had firewall/vpn/whitelist issues then manually running epmd would not have worked |

Looks like it was my company's vpn. They shut if off for me and it started up. So looks like this tracks. Thanks |

epmdis started by the runtime when the node starts.There aren't that many factors that can influence
epmdand the node's clustering and distribution infrastructure: port access, hostname resolution (includinglocalhost), and general OS-level permissions.Two other runtime processes that may be less obvious are
erl_child_setupandbeam.smp(the latter is the runtime that runs RabbitMQ).
