Python openshift上redis的代理错误

我正在openshift上运行一个python应用程序，使用redis作为数据存储

在过去的几天里，该应用程序已经停止工作

当我通过邮递员向我的应用程序发送请求时，我看到：

Proxy Error

The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request GET /index.

Reason: Error reading from remote server

当我登录到我的应用程序时：

$ rhc tail myapp

我明白了：

这个错误看起来更像是上游web服务器代理您的uwsgi应用程序，而不是redis故障。换句话说，似乎是web服务器连接到你的应用程序而不是你的应用程序连接到redis的问题。redis日志看起来正在启动并运行良好。“已在使用”错误看起来像是你正在尝试重新启动应用程序，但它无法启动，因为它已在运行，如果没有进一步的信息，我会认为你的应用程序已挂起。你能强制终止你的应用程序进程，然后尝试重新启动它吗？我已经从gui内部重新启动了应用程序。然而，我仍然得到同样的错误。请看上面的输出。redis日志没有问题。您的redis服务器已启动并运行良好。在您发布的日志中，唯一一件看起来与众不同的事情就是已经在使用的地址——这表明您已经在端口8080上运行了其他东西，并且您的应用程序因此无法启动，或者您现有的应用程序没有正常关闭并且仍在运行。您对服务器的访问级别是什么？如果您有终端访问权限，您应该能够通过运行netstat-anp | grep80808080i获得的：sudo netstat-anp | grep8080 bash:/usr/bin/sudo:Permission来确定绑定端口8080的进程denied@user61629

netstat--listen—侦听端口的inet
