Question

我有一个带有Rails 5.1，Phusion_Passenger和Nginx的服务器。

当我使用Phusion_Passenger启动服务器时，一切都很好：

=============== Phusion Passenger Standalone web server started ===============
PID file: /project/tmp/pids/passenger.3000.pid
Log file: /project/log/passenger.3000.log
Environment: development
Accessible via: http://0.0.0.0:3000/

You can stop Phusion Passenger Standalone by pressing Ctrl-C.

当我尝试使用Nginx作为叠加层启动并访问同一个实例时，出现以下错误：

App 8129 stdout:

  Message from application: Cannot load `Rails.application.database_configuration`:

当您使用Nginx加载rails应用程序时，它似乎无法访问＆＃34; Rails＆＃34;对象

Answer 1

Passenger没有在passenger.conf中设置默认环境。添加了此变量并修复了问题。

passenger_app_env development;

Rails 5.1 + Nginx + Phusion_Passenger的Rails.application.database_configuration错误
