带Riak的eJabberd

Question

我已经配置了Riak集群，一切正常。我将ejabberd.yml配置为与其对话，但我在日志中看到的最后几行如下所示，我不知道如何进一步调试它。

有人能帮上忙吗？

我设法通过ejabberdctl debug获得了更多细节。它似乎有一个节点名称的问题，但完全相同的配置可以很好地工作，如果我不添加Riak到ejabberd.yml文件中。

*更新*

发生这种情况的原因是因为我没有在Docker run命令中指定--net网络连接，所以它找不到网络。不幸的是，没有调试表明这一点，它只是永远挂起(这将发生在一般情况下，托管Riak集群的网络找不到，调试是一个噩梦)。

我仍然不知道为什么"debug“标志会导致tty被添加到节点名称中，但我怀疑这与我修复它时也不再出现tty有某种关系。

Answer 1

您正在使用无效的节点名启动Erlang VM：

{error_logger,{{2016,2,4},{19,30,38}},"Invalid node name: ~p~n",['debug-not a tty-ejabberd@xmpp']}

检查您在哪里配置了这个：'debug-not a tty-ejabberd@xmpp'，因为它确实不是有效的Erlang集群节点名称。
