用Capistrano部署的問題（符號鏈接錯誤）

當試圖部署到我的登臺服務器時，當Capistrano試圖創建database.yml文件時，我看到一個錯誤。用Capistrano部署的問題（符號鏈接錯誤）

目前我在我的gitIgnore文件中有database.yml文件（我曾試過包括它）。

我從來沒有遇到過這個問題，所以我沒有真正知道如何去調試這個問題。

任何幫助深表感謝。

看起來你正在使用一些自定義Capistrano的食譜處理database.yml的，請把它們 – cthulhu 2013-02-19 17:41:39

只是加了我deploy.rb的內容文件，希望它有幫助。 – 2013-02-19 17:45:14

它看起來像你的答案就在你的眼前。

** [out :: example.com] ln: creating symbolic link `/home/deploy/example.com/releases/20130219164028/config/database.yml' 
** [out :: example.com] : File exists

修改您的部署：copy_database_yml先刪除符號鏈接，或者只有當它不存在，創建它。順便說一句，這個任務的作用遠不止它的名字，這是不好的。

這似乎是創建符號鏈接時的Capistrano問題。

試評在deploy.rb文件中的角色：
