我剛在我的ubuntu服務器上安裝乘客（apache2），將我的rails 3.1 rc4 rails應用程序部署到野外，並希望從sqlite更改爲mysql。Rails 3.1與mysql2 rc4問題
我安裝了必要的Ubuntu軟件包
我更新了我的Gemfile與建議：
gem 'mysql2'
並更新了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
當我嘗試創建生產數據庫與耙：
rake db：migrate RAILS_ENV =「生產的」 --trace
它給了我一堆瘋狂的錯誤
** Invoke db:migrate (first_time)
** Invoke environment (first_time)
** Execute environment
rake aborted!
」production」 database is not configured

(And so on)
我試圖安裝mysql的定期寶石，也沒有工作。我也曾嘗試mysql2的< 0.3，但是這似乎導致錯誤被扔在抱怨使用0.2版本的軌道3.1 RC4
我真的很爲難：/
