運行 MySQL 時出現 XAMPP 錯誤

Question

我有問題女巫 XAMPP。 當我嘗試運行 MySQL 時，XAMPP 顯示：

12:37:02  [mysql]   Error: MySQL shutdown unexpectedly.
12:37:02  [mysql]   This may be due to a blocked port, missing  dependencies, 
12:37:02  [mysql]   improper privileges, a crash, or a shutdown by another method.
12:37:02  [mysql]   Press the Logs button to view error logs and check
12:37:02  [mysql]   the Windows Event Viewer for more clues
12:37:02  [mysql]   If you need more help, copy and post this
12:37:02  [mysql]   entire log window on the forums

我已將C:\\xampp\\mysql\\bin\\my.ini和C:\\xampp\\php\\php.ini中的mysql.default_port=3307 mysqli.default_port=3307 。

我還刪除了C:\\xampp\\mysql\\data ib_logfile1 ，但它仍然不起作用。 錯誤日志：

任何幫助表示贊賞。 謝謝

Answer 1

MySQL確切地告訴您為什么它無法啟動：

[錯誤] InnoDB：無法創建C：\\ xampp \\ mysql \\ data \\ ib_logfile101

因此，我建議您要做的第一件事是檢查c：\\ xampp \\ mysql \\ data是否存在並且可由DBMS用戶寫入。

Answer 2

首先在xampp控制面板上停止該服務，然后單擊左側的紅叉以在您的計算機上安裝該服務，然后該圖標將變為綠色的勾號，然后以管理員身份啟動該服務。

它應該工作正常。

Answer 3

1. 打開 XAMPP 控制面板並停止操作。
2. 打開服務，進入MySql80。
3. 停止服務。
4. 啟動服務。
