Question

This image will help you to find the issue我在ubunu 16.04 LTS上配置了Openstack newton。它工作正常现在我已经计划将穆拉诺融入其中。所有进展都很好。当我使用“ tox -e venv -- python manage.py runserver <IP:PORT> ”命令运行仪表板时。我能够运行murano仪表板。

当我访问环境标签时，它显示错误

错误：与服务器通信时出错。

并且日志消息显示错误

没有名为memcache的模块

以下是您的参考错误消息：

有人可以帮忙吗？在此先感谢。

Answer 1

仅安装memcached是不够的。您还需要安装python memcache模块，该模块由python-memcache和python-pymemcache单独提供。我不确定在这里使用哪一个。

您可以尝试使用apt-get安装它们，看看哪个适合您。

Answer 2

现在正在工作..我在不同的venv安装了murano api和murano仪表板。我错过了在munano api venv中安装memcache。当我在murano api venv中安装memcache后试用。现在正常工作..

@tutuDajuju感谢您的帮助...

访问murano仪表板时，openstack newton keystone中的“没有名为memcache的模块”错误
