第一次更改主机名后，rabbitmq-server 无法启动 [英] rabbitmq-server fails to start after hostname has changed for first time
问题描述
我在我的 django 项目中使用 django-celery.昨天我更改了计算机的主机名(我使用的是 Ubuntu 12.04，编辑了文件 '/etc/hostname')，下次重新启动 django-celery 失败并出现错误
I am using django-celery for my django project. Last day I have changed my computer's hostname (I am using Ubuntu 12.04, edited file '/etc/hostname'), and after next restart django-celery was failing with error
Consumer: Connection Error: [Errno 111] Connection refused. Trying again in 4 seconds...
在对此错误进行一些研究后，我发现，更改我的主机名会导致此错误来自 这里.我的rabbitmq启动日志显示
After some research on this error I could find that, changing my host name caused this error from here. My rabbitmq startup log shows
文件:/var/log/rabbitmq/startup_log
file: /var/log/rabbitmq/startup_log
Activating RabbitMQ plugins ...

我的 startup_err 文件是空的.
My startup_err file is empty.
当我跑步时
root@jinesh:/home/jinesh# rabbitmqctl list_users
Listing users ...
Error: unable to connect to node rabbit@jinesh: nodedown
