Celery + RabbitMQ 卡在 mingle：寻找邻居答案

【问题标题】：Celery + RabbitMQ stuck at mingle: searching for neighborsCelery + RabbitMQ 卡在 mingle：寻找邻居
【发布时间】：2015-01-08 00:05:25
【问题描述】：

我在尝试让我的系统在新机器上运行时遇到了奇怪的问题。

操作系统：

Ubuntu 14.04.1 LTS（GNU/Linux 3.13.0-39-generic x86_64）

包：

芹菜==3.1.13

django-celery==3.0.23

librabbitmq==1.5.2

经纪人：

RabbitMQ“3.2.4”

重启后Celery进程卡住：

[2014-11-10 18:32:55,792: INFO/MainProcess] Connected to amqp://user:**@172.16.10.6:5672/vhost
[2014-11-10 18:32:55,804: INFO/MainProcess] mingle: searching for neighbors

试图在其他地方找到解决方案。 Here 我找到了增加 RabbitMQ 可用磁盘空间的建议。我检查了docs 并在 rabbitmq.config 文件中进行了更改：

{disk_free_limit, {mem_relative, 1.0}}

现在 RabbitMQ 应该有 6GB 可用空间，但它不会将 Celery 推入就绪状态。我还尝试在

中配置（正如有人建议的那样）打开文件描述符的限制

/etc/default/rabbitmq-server

没有任何影响。当前 RabbitMQ 状态：

    [{pid,4131},
 {running_applications,
     [{rabbitmq_management,"RabbitMQ Management Console","3.2.4"},
      {rabbitmq_web_dispatch,"RabbitMQ Web Dispatcher","3.2.4"},

 {processes,[{limit,1048576},{used,270}]},
 {run_queue,0},
 {uptime,4561}]

另一件事：当我使用 Supervisor 停止 Celery 进程时，没有记录任何热关机（实际上 - 没有记录任何内容）。

你能帮忙吗？

我似乎遇到了同样的问题。在此处查看我对自己问题的回答：

celeryd with RabbitMQ hangs on "mingle: searching for neighbors", but plain celery works

长话短说：

sudo apt-get 删除 librabbitmq1

为我工作。
