RabbitMQ – EPMD Reports: Node ‘rabbit’ Not Running at All

My RabbitMQ used to run just fine on my Ubuntu 16.04 LTS server, but suddenly it just refuses to start.

The hostname of the server is canvas1.

I installed it using standard apt-get approach:

sudo apt-get update
sudo apt-get install rabbitmq-server

I've tried sudo rm -rf /var/log/rabbitmq/* suggested by this thread and it doesn't help.

I've tried sudo rm -rf /var/lib/rabbitmq/mnesia/* then restart, and it didn't work.

I've also tried adding 127.0.0.0 canvas1 to /etc/hosts, and adding export ERL_EPMD_ADDRESS=127.0.0.1 to /etc/default/rabbitmq-server, but none of them worked.

I've tried uninstall the rabbitmq-server, purge it, and autoremove and autopurge, then reinstall the rabbitmq-server, and it doesn't work, either.

Here is the log shown by sudo service rabbitmq-server status:

Crash dump is being written to: erl_crash.dump...done

and there is no /var/log/rabbitmq/rabbit@canvas1.log. All the files in /var/log/rabbitmq/ is startup_log and startup_err.

There's no dets files in /var/lib/rabbitmq/mnesia either. Only a pid file there, and there's no process with that pid.

The erl_crash.dump can be found here: https://drive.google.com/file/d/1aRSQ-DXkMUZr2domAB-oc6AbeI6-y07c/view?usp=sharing

How can I solve this problem?
