这里的问题是，所有的东西都配置好了，运行起来没有错误，但是我不知道为什么它不工作。你会看到我没有应用程序无法加载错误，我没有任何错误，事实上，这是最完整的没有错误，我已经从我开始。然而，有500人回应。这里有很多是为了完整性，我将解释。如果我把皇帝排除在外，那就好了。在

我一直在尝试通过uwsgi/nginx部署一个开源flask应用ceph dash进行监控。我最终成功了，尽管很痛苦。我写了一篇关于我成功的要点

然而，由于没有守护进程管理和诸如此类的东西，我认为最好通过使用uwsgi皇帝来添加我所做的事情，因此我严格遵循了这个指南 https://chriswarrick.com/blog/2016/02/10/deploying-python-web-apps-with-nginx-and-uwsgi-emperor/

我在Centos 7。我已经在这个实现上成功运行和测试了这个应用程序，正如你在要点中看到的，我实际上是特意发现了如何在不同的场景下配置uwsgi。在

但是对于wsgi的皇帝实现和它的所有配置文件。我收到一个500响应的内部服务器错误。我想这是因为nginx和皇帝或者皇帝之间的关系。当我停止uwsgi服务时，我得到了502。所以nginx至少可以看到socket文件。在

我已经卸载了我通过pip安装的uwsgi。我似乎仍然有一个/sbin/uwsgi（链接自/usr/sbin），它看起来是为systemd安装的，/usr/bin/uwsgi我不知道是怎么回事。我将.service文件改为使用/usr/bin，并且有相同的错误。但是rpm中的二进制文件没有安装插件，而/usr/bin中的插件安装了。systemd uwsgi现在以/usr/bin/uwsgi开始，正如您在下面看到的那样，二进制加载所需的插件，但是我得到了相同的内部服务器错误，来自systemd和startup的相同消息没有错误，没有失败。只有500英镑。在

由yum和pip安装的uWSGI是不同的。Systemd可能会使用yum安装的一个。当您自己SSH'ing并运行uWSGI时，系统将默认使用pip安装的uWSGI。在

这两个uWSGI版本之间的主要区别是：在yum安装的版本中缺少python支持，因为它倾向于模块化。您可以使用yum install uwsgi-python（检查您的发行库中的特定包名）来安装它。请注意，不同的python版本需要不同的python插件（2.7将需要不同于3.5的插件），并相应地调整要安装的包名。在

安装python插件后，检查插件名称（对uWSGI可见）并调整.ini文件中plugins中的值。该名称可能与没有uwsgi-前缀的已安装包名称匹配。在
