轨道控制台工程，但轨道服务器不工作

Question

嗨我遇到了一个问题，这对我来说没有意义。

在我的托管服务器上，我有一个我想运行的应用程序。我可以使用capistrano来部署应用程序。我也能够毫无问题地运行bundle exec rails console production。但是，当我尝试运行bundle exec rails server时，它将退出并显示以下错误消息。

    from bin/rails:4:in `<main>' 

所以它好像不喜欢我的database.yml文件。这是我database.yml

production: 
    adapter: mysql2 
    database: asavale1_dejalearn 
    username: ENV['DB_USER'] 
    password: ENV['DB_PASS'] 
    pool: 5 
    timeout: 5000 

为什么我能够运行bundle exec rails console production但抱怨适配器，当我尝试运行我的Rails服务器。不要使用同一个databse.yml文件连接到数据库吗？我的RAILS_ENV是生产。

感谢

它看起来像你明确地开始在生产环境中的控制台，并在（默认）开发环境中的服务器。尝试运行bundle exec rails server -e $RAILS_ENV。如果这不起作用，请尝试bundle exec rails server -e production。
