Question

对于Openshift上的Python 3.3盒和PostgreSQL 9.2。

当我进入Openshift应用程序时，我可以看到OPENSHIFT_POSTGRESQL_DB_HOST的内容：

echo $OPENSHIFT_POSTGRESQL_DB_PORT
5432

但是对于wsgi脚本，不会传递env变量 - 请参阅python.log中的部分：

在应用程序控制台中重新启动应用程序没有帮助。都没有重启python盒。

请建议如何将env变量传播到wsgi脚本。

Answer 1

尝试停止＆amp;启动（不重启）你的python应用程序，特别是如果你在创建应用程序后添加了postgresql。由于它作为wsgi应用程序在apache中运行，因此可能需要停止/启动才能正确查看env变量。

Answer 2

支持@developercorey

的答案

尝试停止＆amp;启动（不重启）你的python应用程序......

根据文档执行此操作的命令 from here是：

$ rhc app-stop {instance}

或

$ rhc app-force-stop {instance}

和

rhc app-start {instance}

注意： 将{instance}更改为您的Openshift应用程序名称。

在Openshift中未定义PassEnv变量OPENSHIFT_POSTGRESQL_DB_HOST
