我在EC2上运行django / celery，以Rabbitmq作为代理。我使用的计算机发生故障，因此启动了另一个实例。但是自从改用新机器以来，我一直无法让芹菜上班。
编辑：为了防止误诊，我在下面添加了很多日志。但是我有85％的肯定是问题是Rabbitmq-server在“启动数据库”阶段无法启动。
node : rabbit@ip-10-212-66-181
app descriptor: /usr/lib/rabbitmq/lib/rabbitmq_server-1.7.2/sbin/../ebin/rabbit.app
home dir : /var/lib/rabbitmq
cookie hash : 5+uQ077En5bpvle3HJCQMg==
log : /var/log/rabbitmq/rabbit.log
sasl log : /var/log/rabbitmq/rabbit-sasl.log
database dir : /var/lib/rabbitmq/mnesia/rabbit
starting internal event notification system ...done
starting logging server ...done
starting database ...Erlang has closed
关于如何进一步诊断/解决此问题的任何想法？
当我尝试运行芹菜时，会发生以下情况：
$ python manage.py celeryd -l info

追溯它，看起来是Rabbitmq服务器是问题所在，尤其是数据库：
$ sudo rabbitmqctl status
Status of node 'rabbit@ip-10-212-66-181' ...
Error: unable to connect to node 'rabbit@ip-10-212-66-181': nodedown
diagnostics:
- nodes and their ports on ip-10-212-66-181: [{rabbitmqctl14448,38289}]
- current node: 'rabbitmqctl14448@ip-10-212-66-181'
- current node home dir: /var/lib/rabbitmq
- current node cookie hash: 5+uQ077En5bpvle3HJCQMg==
但是我还无法弄清楚如何重新启动服务器：
bitnami@ip-10-212-66-181:/var/log/rabbitmq$ sudo rabbitmq-server start_app

另外，不知道它是否相关，但是此过程正在后台运行。

我没有找到任何有关此类失败的文档。有什么建议么？
