14:29 shakakai: hey all, i'm having a little issue with clustering rabbitmq http://stackoverflow.com/questions/6948624/mnesia-cant-connect-to-another-node
14:30 shakakai: has anyone run into that problem before?
14:30 daysmen has left IRC (Read error: Connection reset by peer)
14:30 antares_: shakakai: make sure that epmd is running on every node
14:30 antares_: shakakai: and that port it uses (4369) is open in your firewall
14:31 |Blaze|: shakakai: is your dns correct? Can you ping worker1 from celery and celery from worker1
14:31 shakakai: |Blaze|: hmm...i'll check
14:31 daysmen has joined (~quassel@host-84-13-157-50.opaltelecom.net)
14:32 shakakai: |Blaze|: this is where I'm a little confused, the rabbitmq nodename is worker1@worker1 but the fqdn to ping the box is "ping worker1.mydomain.com"
14:33 |Blaze|: can you "ping worker1"
14:34 shakakai: |Blaze|: no
14:34 |Blaze|: k, you'll need to fix that
14:34 hyperboreean has left IRC (Ping timeout: 250 seconds)
14:37 shakakai: |Blaze|: gotcha, so I setup a hosts file and i should be good
14:37 |Blaze|: yup
14:37 |Blaze|: in both directions
确保可以从集群中的每个框ping兔子节点名。如果不能，请为每个兔子节点名设置一个hosts文件。在让集群正常工作之前，有几件事需要检查： 0）确保在每个节点上运行完全相同的rabbitmq版本 1） 设置网络，直到您能够相互ping每个服务器 2） cookies-您必须在每台服务器上的.erlang.cookie文件中获得完全相同的erlang cookie 一个有用的技巧是从一个节点尝试此命令，看看是否可以从rabbitmq访问另一个节点 rabbitmqctl评估网络管理：ping(rabbit@othernode).' 如果是nok，应该是Pang，如果是ok，应该是pong 注意不要忘记靠近求值表达式末尾的点 经过几个小时不成功的试验，我使它运行良好 3） 请记住，如果此节点不是最后一个停止的节点，则在重新启动群集节点时可能会出现问题-它不会在最后一个停止重新启动之前启动。 当以上（0到2）都正确时，3很可能是问题的根本原因 希望这有帮助,， 干杯
jb我读到的一件事是，erlang cookie需要位于所有集群节点上，以便它们能够通信。我相信它存在于/var/lib/rabbitmq/.erlang.cookie中我安装Docker rabbitmq的过程中也遇到了类似的问题 主要原因是
/var/lib/RabbitMQ/mnesia/rabbit/cluster_nodes.configrabbit@cb43449d5d72我不认为接受你自己的答案是禁忌，尤其是因为它是一个好的答案
