xampp mysql 和 phpmyadmin 不起作用

Question

昨天我和我的 xampp 一起工作，我使用了 apache 和 mysql 服務。 今天我想啟動mysql服務，但沒有成功。 我試圖在論壇上搜索解決方案，但我找不到任何東西，所以我問你。

在 mysql 停止工作后，我在日志文件中找到了這條消息：

你能幫我解決這個問題嗎？

Answer 1

我已經解決了這個問題。 從 xampp/mysql/backup/ 文件夾中，我將所有文件復制到 xampp/mysql/data/ 這解決了問題。

Answer 2

我今天遇到了類似的問題，並且能夠通過以下方式解決它：

1. 關閉 XAMPP 控制面板

2. 刪除/xampp/mysql/data下的以下文件：

   • aria_log.**1
   • aria_log_control
   • ib_logfile0
   • ib_logfile1
   • ibdata1
   • ibtmp1
   • mysqld.pid

3. 並修改 multi-master.info 並刪除其所有內容，然后保存文件。

4. 打開 Xampp 並再次運行 mysql。

Answer 3

作為正確答案的補充，您不需要刪除xampp/mysql/data/所有文件，只需替換為xampp/mysql/backup/任何內容即可。 干杯

Answer 4

從 xampp/mysql/backup/ 文件夾復制所有文件並將它們粘貼到 xampp/mysql/data/
