openstack octavia : amphora worker异常

Question

我正在尝试运行openstack Octavia，遵循以下说明

https://docs.openstack.org/octavia/latest/contributor/guides/dev-quick-start.html

当我启动Octavia-worker时，我遇到了以下异常：

 2018-10-18 19:00:47.765 16044 INFO octavia.controller.queue.consumer [-]   Starting consumer...
 2018-10-18 19:00:49.103 16044 ERROR cotyledon._utils [-] Unhandled exception: ImportError: cannot import name opentype

我正在使用Octavia 1.0.2和openstack pike。我不确定这个导入错误"opentype“是从哪里来的。丢失了什么包？谢谢你的帮助。

下面修复了这个问题(发布在这里是为了帮助其他可能遇到同样问题的人)：

pip install --upgrade pyasn1-modules 

现在我明白了

 Unhandled exception: InvalidTarget: A server's target must have topic and server names specified:<Target server=neutron01>
2018-10-18 19:37:06.864 23338 ERROR cotyledon._utils Traceback (most recent call last):
   2018-10-18 19:37:06.864 23338 ERROR cotyledon._utils     File "/usr/local/lib/python2.7/dist-packages/cotyledon/_utils.py", line 95, in    exit_on_exception
2018-10-18 19:37:06.864 23338 ERROR cotyledon._utils     yield

我在Octavia.conf中取消了下面的注释，这使得这个问题消失了

 [oslo_messaging]
 topic = octavia_prov

# Topic for octavia's events sent to a queue
 event_stream_topic = neutron_lbaas_event

但如果我知道我在做什么就好了。
