/config/database.yml在部署的.gitignore /config/database.yml沒有找到應該使用/shared/database.yml，怎麼樣？

Question

我跟着文檔帽+的nginx +獨角獸但是有一些問題，以瞭解如何正確地做數據庫部署。

• /config/database.yml不應該是在git倉庫中放置/shared/database.yml的database.yml中
• 問題的生產服務器上（最好）
• 是，在部署還是尋找/config/database.yml

我怎樣才能讓我的deploy.rb搶/shared/database.yml呢？ 搜索高和低這無濟於事:(

我使用了一個非常類似的deploy.rb，但我已經在我的finalize_update方法多了一個符號鏈接：

ln -sf #{shared_path}/database.yml #{latest_release}/config/database.yml
