MySQL 會話不會在 XAMPP 上啟動

Question

我的 MySQL 無法啟動，顯示如下：

12:50:50  [mysql]   Error: MySQL shutdown unexpectedly.
12:50:50  [mysql]   This may be due to a blocked port, missing dependencies, 
12:50:50  [mysql]   improper privileges, a crash, or a shutdown by another method.
12:50:50  [mysql]   Press the Logs button to view error logs and check
12:50:50  [mysql]   the Windows Event Viewer for more clues
12:50:50  [mysql]   If you need more help, copy and post this
12:50:50  [mysql]   entire log window on the forums

然后這是錯誤日志：

這些錯誤的原因是什么，我該如何糾正它們？

太感謝了。

Answer 1

對於這個問題去：

c:\\xampp\\mysql\\data\\

並刪除除目錄之外的所有文件

以防萬一保留my.ini，如果再次出錯，也刪除my.ini。

我希望它能幫助你。

Answer 2

非常容易

按照步驟

1.去 xampp\\mysql\\backup 從備份文件夾復制所有內容然后

2.轉到 xampp\\mysql\\data 粘貼從備份文件夾復制的數據文件夾中的所有內容

重新啟動 xampp 並啟動​​所有。謝謝。
