我刚在我的ubuntu服务器上安装乘客（apache2），将我的rails 3.1 rc4 rails应用程序部署到野外，并希望从sqlite更改为mysql。Rails 3.1与mysql2 rc4问题
我安装了必要的Ubuntu软件包
我更新了我的Gemfile与建议：
gem 'mysql2'
并更新了database.yml文件
production:
adapter: mysql2
database: database
username: deploy
password: (***blocked for security reasons***)
socket: /var/run/mysqld/mysqld.sock
pool: 5
timeout: 5000
当我尝试创建生产数据库与耙：
rake db：migrate RAILS_ENV =“生产的” --trace
它给了我一堆疯狂的错误
** Invoke db:migrate (first_time)
** Invoke environment (first_time)
** Execute environment
rake aborted!
”production” database is not configured

(And so on)
我试图安装mysql的定期宝石，也没有工作。我也曾尝试mysql2的< 0.3，但是这似乎导致错误被扔在抱怨使用0.2版本的轨道3.1 RC4
我真的很为难：/
