我沒有看到任何在端口3306上監聽的東西。你是否成功使用某個客戶端連接到你的mysql實例？ mysqladmin也許？另外這一行： ''' socket：/var/run/mysqld/mysqld.sock '''' 看起來不像win8上的工作。而最重要的是：老兄，只是使用Linux進行開發。 – cthulhu 2014-12-04 00:09:43

您的錯誤Can't connect to MySQL server on '127.0.0.1'通常意味着您的MySQL服務未運行。您確定您已將您的應用程序指向您的數據庫服務的正確主機和端口嗎？

我不確定我是否擁有所有正確的文件。在'Program Files（x86）/ MySQL'下，我只有一個文件夾，'MySQL Connector C 6.1' – Darkmouse 2014-12-04 00:00:36

是的，MySQL在端口3306上運行。我也嘗試過，沒有端口和主機字段 – Darkmouse 2014-12-04 00:26:31
