epmd 報告：節點“兔子”根本沒有執行

我的 RabbitMQ 曾經在我的 Ubuntu 16.04 LTS 伺服器上執行得很好，但突然它只是拒絕啟動。

伺服器的主機名是canvas1。

我使用標準的 apt-get 方法安裝了它：

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

我已經嘗試過this threadsudo rm -rf /var/log/rabbitmq/*的建議，但沒有幫助。

我試過sudo rm -rf /var/lib/rabbitmq/mnesia/*然後重新啟動，它沒有工作。

我也嘗試過 add 127.0.0.0 canvas1to/etc/hosts和 add export ERL_EPMD_ADDRESS=127.0.0.1to /etc/default/rabbitmq-server，但都沒有奏效。

我試過解除安裝rabbitmq-server，清除它，然後自動刪除和自動清除，然後重新安裝rabbitmq-server，它也不起作用。

這是顯示的日誌sudo service rabbitmq-server status：

和中的內容/var/log/rabbitmq/startup_err：

init terminating in do_boot (noproc)

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

並且沒有/var/log/rabbitmq/rabbit@canvas1.log。中的所有文件/var/log/rabbitmq/都是startup_log和startup_err.

也沒有dets文件/var/lib/rabbitmq/mnesia。那裡只有一個 pid 文件，並且沒有該 pid 的程序。

erl_crash.dump可以在這裡找到：https ://drive.google.com/file/d/1aRSQ-DXkMUZr2domAB-oc6AbeI6-y07c/view?usp=sharing

我怎麼解決這個問題？

似乎 RabbitMQ 在 Ubuntu 上不能很好地與 esl-erlang 配合使用，但我不知道為什麼。

完全解除安裝 RabbitMQ 和 esl-erlang 後，僅重新安裝 RabbitMQ，一切正常。
