Ruby on Rails項目與Mysql數據庫

我是ror的初學者。我正在研究Ubuntu。Ruby on Rails項目與Mysql數據庫

我可以用默認數據庫創建一個新的ror項目，沒有任何問題，一切都是okey ..但我想創建一個具有mysql數據庫的項目。

我使用這個命令：

railse new myproject -d mysql

然後，我把我的MySQL用戶名和passwork在database.myl文件，但是當我嘗試啓動服務器，因此它不工作，我收到此錯誤信息：

=> Booting WEBrick 
=> Rails 3.2.13 application starting in development on http://0.0.0.0:3000 
=> Call with -d to detach 
=> Ctrl-C to shutdown server

它可能在你的database.yml文件錯字的錯誤，我可以看到你的database.yml文件 – bernabas 2013-04-22 20:55:48

是，請您出示的database.yml內容 - 但不要告訴我們你的真實用戶名和密碼 – weltschmerz 2013-04-22 20:57:37

'測試：適配器：mysql2 編碼：UTF8 重新連接：假數據庫：neistersin_test 池：5 用戶名：root密碼：123456 插座：在/ var /運行/ mysqld的/ mysqld.sock' 同爲生產和測試 – Mehmet 2013-04-22 21:06:07

在database.yml中：

密碼：123

應該是

密碼： '123'

注：「

這可能不是最終的解決方案，但對接近問題的第一步。
