OpenShift 错误在此服务器上找不到请求的 URL /答案

【问题标题】：OpenShift Error The requested URL / was not found on this serverOpenShift 错误在此服务器上找不到请求的 URL /
【发布时间】：2015-07-22 00:16:46
【问题描述】：

我一直在尝试在 openshift 上部署一个烧瓶应用程序。我测试了网站，它在开发服务器上运行良好（通过键入 python app.py 和 manage.py runserver），我将项目上传到 github 并使用终端中的以下命令创建了应用程序：

rhc create-app marcsantiago python-2.7 --from-code=https://github.com/marcsantiago/personalwebsite.git

应用程序的创建似乎没有问题。当我尝试访问创建的 url 时出现问题：

http://marcsantiago-mywebappsflask.rhcloud.com

我收到未找到错误请求的 URL / 未在此服务器上找到。

我不明白我做错了什么或如何修复它以使网站正常运行。这是一个简单的网站，不使用数据库。

有人可以帮我解决这个问题吗？

这是 postgresql.log 信息，虽然我不确定它的相关性，因为我不使用数据库，python.log 在下面

抱歉，它看起来很乱，除了将它们粘贴进去之外，想不出更好的方法来共享日志。

【问题讨论】：

WSGI 脚本文件必须在顶级目录中命名为“wsgi.py”，如果使用 Apache/mod_wsgi，则为“wsgi/application”文件。您似乎都没有使用过。如果不想使用 Apache/mod_wsgi 但提供启动自己的 HTTP 服务器的 Python 脚本，则需要将其命名为“app.py”。
您似乎也已经在实例上运行了 Apache。您可能想要重新启动实例，如果这没有帮助，您可能必须通过 ssh 进入实例并终止 Apache 实例，因为您可能以某种方式使其进入混乱状态。
你能提供一些代码吗？

标签： python-2.7 flask openshift

【解决方案1】：

您是否尝试过阅读开发人员门户中关于在 OpenShift Online 上使用 Flask 的部分？

https://developers.openshift.com/en/python-flask.html

【解决方案2】：

域没有指向任何服务器。

这很可能是您在 Openshift 上的配置中的问题、服务器配置中的错误或您的 URL 输入错误。

联系 Openshift 或查看他们的日志。

编辑： 查看新日志，很明显服务器找不到您的 WSGI 应用程序。您提到它被称为 app.py，但服务器可能正在寻找其他东西。更常见的文件名是 application.py。检查您在 OpenShift 上的配置并相应地调整 WSGI 应用程序文件名。

【讨论】：

我刚刚删除了应用程序，我会重新安装它
请分享您的日志信息。就目前而言，我们无法弄清楚发生了什么。
我改名为application.py，重新上传了app。没什么，同样的问题，我对 openshift 真的很陌生，比如 12 小时新，所以我现在不知道如何编辑配置。无论如何，我认为这是我在 github 上的烧瓶结构。我将按照此链接blog.openshift.com/… 为 openshift 设置我的烧瓶项目。
