Comment 15 for bug 1784757

# forgot to include the shutdown changes, so here's a full procedure to fix this in Bionic:

sudo nano /lib/systemd/system/rabbitmq-server.service

# fixup the [Unit] entry to look like this:
[Unit]
Description=RabbitMQ Messaging Server
After=network.target epmd@0.0.0.0.socket
Wants=network.target epmd@0.0.0.0.socket

# change just the ExecStop under [Service] to use "shutdown" instead of "stop":
ExecStop=/usr/sbin/rabbitmqctl shutdown

# reload and reboot:
sudo systemctl stop rabbitmq-server.service
sudo systemctl daemon-reload
sudo systemctl restart rabbitmq-server.service
sudo shutdown -r now
