我如何才能将OpenShift的日志尾部添加到有关python setup.py，virtualenv和pip的详细信息？

Question

当我跑步时：

rhc tail -a myapp

我在应用程序启动时确实看到了日志消息流，但是与virtualenv的设置以及在requirements.txt中安装依赖项（例如flask等）无关。为了更好地进行调试，如何更好地在服务器上监视此消息，以防万一我遇到问题了吗？ 这在Heroku中相当容易做到，但是我正在考虑将应用程序迁移到OpenShift，但前提是调试python的选项非常灵活。

当您对应用程序进行git push更改时，OpenShift会以关于setup.py，Requirements.txt等状态的详细输出进行响应。这是从部署到OpenShift上的Python应用程序的示例（缩写）输出：

$ git commit -m "Adds BeautifulSoup"
$ git push

在这种情况下，执行imo的最佳方法是使用ssh。 登录后，您可以进入应用程序目录并直接查看所有日志/配置文件。
