我刚刚使用 MySql 创建了一个新的 Rails 4 应用程序,如下所示:
rails new mysqltest -d mysql
并使用正确的凭据修改了 database.yml。
我生成了一个示例控制器并更新了根路由的路由。
当我开始在生产中使用 WEBrick 时,
rails s -e production
该网站有效。我看到了索引页。
当我开始使用没有 3000 端口的乘客时,我看到以下错误:
database configuration does not specify adapter (ActiveRecord::AdapterNotSpecified)
Passsenger 在生产环境中运行。
我的数据库.yml
