首次更改主机名后，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django项目中使用django-celery。昨天，我更改了计算机的主机名（我正在使用Ubuntu 12.04，已编辑文件'/ etc / hostname'），并且在下次重启后django-celery失败，并显示错误
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...
在对这个错误进行了一些研究之后，我发现，改变了我的主机名从此处导致了此错误。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 ...

0 plugins activated:
ERROR: epmd error for host "jinesh": nxdomain (non-existing domain)
我的startup_err文件为空。
My startup_err file is empty.
我跑步时
root@jinesh:/home/jinesh# rabbitmqctl list_users
Listing users ...
Error: unable to connect to node rabbit@jinesh: nodedown
DIAGNOSTICS
===========
nodes in question: [rabbit@jinesh]
hosts, their running nodes and ports:
- unable to connect to epmd on jinesh: nxdomain
current node details:
- node name: rabbitmqctl4956@jinesh
- home dir: /var/lib/rabbitmq
- cookie hash: RGhmB2JR1LbZ57j7xWWTxg==
我希望更改节点名称可以解决此问题。但是我找不到解决办法。有人知道如何解决此问题吗？
I hope changing the nodename may fix this issue. But I couldn't found a way to do this. Anyone have idea about how solve this issue?
更新
同时更改主机名您必须同时更改 / etc / hostname 和 / etc / hosts 文件。
while changing hostname you have to change both /etc/hostname and /etc/hosts files.
