我的 RabbitMQ 曾经在我的 Ubuntu 16.04 LTS 服务器上运行良好，但突然它拒绝启动。
该服务器的主机名是canvas1。
我使用标准 apt-get 方法安装它：
sudo apt-get update
sudo apt-get install rabbitmq-server
我尝试sudo rm -rf /var/log/rabbitmq/*过此主题但这并没有什么帮助。
我已尝试过sudo rm -rf /var/lib/rabbitmq/mnesia/*重新启动，但是没有作用。
我也尝试过添加127.0.0.0 canvas1到/etc/hosts，并添加export ERL_EPMD_ADDRESS=127.0.0.1到/etc/default/rabbitmq-server，但都没有起作用。
我尝试卸载 rabbitmq-server、清除它并自动删除和自动清除，然后重新安装 rabbitmq-server，但同样不起作用。
以下是显示的日志sudo service rabbitmq-server status：

Crash dump is being written to: erl_crash.dump...done
并且没有。中的所有文件都是和。/var/log/rabbitmq/[email protected]/var/log/rabbitmq/startup_logstartup_err
两者都没有 dets 文件/var/lib/rabbitmq/mnesia。只有一个 pid 文件，并且没有具有该 pid 的进程。
可以erl_crash.dump在这里找到：https://drive.google.com/file/d/1aRSQ-DXkMUZr2domAB-oc6AbeI6-y07c/view?usp=sharing
我怎么解决这个问题？
答案1
看起来 RabbitMQ 不能很好地与 Ubuntu 上的 esl-erlang 配合使用，但我不知道原因。
完全卸载 RabbitMQ 和 esl-erlang 后，仅重新安装 RabbitMQ，一切即可正常运行。
