xampp mysql 和 phpmyadmin 不起作用

Question

昨天我使用我的 xampp，我使用了 apache 和 mysql 服务。 今天我想启动mysql服务并没有工作。我尝试在论坛上搜索解决方案，但我找不到任何东西，所以我问你。

在 mysql 停止工作后，我在日志文件中找到此消息：

你能帮我解决这个问题吗？

Answer 1

我已经解决了这个问题。我将xampp/mysql/backup/中的所有文件复制到xampp/mysql/data/。

Answer 2

我今天遇到了类似的问题，并且能够通过以下方式解决它：

1. 关闭 XAMPP 控制面板

2. 删除/xampp/mysql/data下的以下文件：

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

3. 修改 multi-master.info 并删除其所有内容，然后保存文件。

4. 打开 Xampp 并再次运行 mysql。

Answer 3

作为正确答案的补充，您不需要删除xampp/mysql/data/ 中的所有文件，只需替换xampp/mysql/backup/ 中的任何内容即可。干杯
