Otherwise no client application can connect to the server. After you have opened the port please press [Retry] to apply the security settings.

In this case please select skip now and re-run the Configuration Wizard from the start menu. 解決方法: www.2cto.com 1, 卸載MySQL 2, 刪除目錄 C:\Documents and Settings\All Users\Application Data\MySQL 3, 重新安裝MySQL 就好了 如何你C:\Documents and Settings\All Users下沒有Application Data文件夾,選擇:工具——文件夾選項——查看——選擇顯示所有文件和文件夾 作者 邴輝
