Stackstorm 2.7 webhook“ AccessRefused：403”错误

Question

我已经在stackstorm中成功创建了一个Webhook，它在webhook列表中可见。 [centos@ip- ~]$ sudo st2 webhook list +------------+------------------+-------------+ | url        | type             | description | +------------+------------------+-------------+ | wfcreation | core.st2.webhook |             | +------------+------------------+-------------+ [centos@ip- ~]$我触发了webhook，以提供有效负载并使用stackstorm api键设置适当的标头。Webhook被触发并返回状态码200。但是，基本的stackstorm工作流程失败，并出现以下错误。{  "traceback": "  File \"/opt/stackstorm/st2/lib/python2.7/site-packages/st2actions/container/base.py\", line 119, in _do_run    (status, result, context) = runner.run(action_params)  File \"/opt/stackstorm/st2/lib/python2.7/site-packages/retrying.py\", line 49, in wrapped_f    return Retrying(*dargs, **dkw).call(f, *args, **kw)  File \"/opt/stackstorm/st2/lib/python2.7/site-packages/retrying.py\", line 206, in call    return attempt.get(self._wrap_exception)  File \"/opt/stackstorm/st2/lib/python2.7/site-packages/retrying.py\", line 247, in get    six.reraise(self.value[0], self.value[1], self.value[2])  File \"/opt/stackstorm/st2/lib/python2.7/site-packages/retrying.py\", line 200, in call    attempt = Attempt(fn(*args, **kwargs), attempt_number, False)  File \"/opt/stackstorm/runners/mistral_v2/mistral_v2/mistral_v2.py\", line 247, in run    result = self.start_workflow(action_parameters=action_parameters)  File \"/opt/stackstorm/runners/mistral_v2/mistral_v2/mistral_v2.py\", line 284, in start_workflow    **options)}   官方的stakstorm文档没有任何有关对此错误进行故障排除的参考。

Answer 1

最终，我能够找出问题出在stackstorm主机上运行的mistral-server服务。

问题在于，由于stackstorm安装期间的配置错误，导致mistral-server服务无法连接到Rabbitmq服务。但是误导性错误消息“ AccessRefused：403”没有指出与Rabbitmq连接有关的问题。

这就是我在日志中找到的内容。

错误日志（/ var / log / mistral /）中的错误消息：

2018-06-25 15:30:19.309 10767 ERROR oslo_service.service AccessRefused: (0,0): (403) ACCESS_REFUSED - Login was refused using authentication mechanism AMQPLAIN. For details see the broker logfile.

在挖出Rabbitmq日志（/ var / log / rabbitmq /）时：

=ERROR REPORT==== 25-Jun-2018::16:34:23 ===

closing AMQP connection <0.5118.0> (127.0.0.1:41248 -> 127.0.0.1:5672):

{handshake_error,starting,0,

             {amqp_error,access_refused,

                         "AMQPLAIN login refused: user 'st2' - invalid credentials",

                         'connection.start_ok'}}

显然，在安装过程中错误地配置了st2用户凭据，这导致了整个问题。
