Xampp mysql 服务器突然不启动

Question

几个小时前我使用了 Xampp 想再次启动 mysql 服务器但是它给了我一条错误消息说 mysql 意外关闭 enter image description here

是的，端口未被使用，用 netstat -an 检查了它 | findstr "3306" 命令甚至尝试将端口更改为 3307，但都不起作用

并且错误日志显示没有错误：

如果您的 MySql 是新的，没有重要的数据库，您可以尝试以下步骤：

关闭您的 Xampp 服务器
转到C:\xampp\mysql\data目录
删除 ibdata1 文件
重新启动您的 Xampp 服务器

删除 ibdata1 文件可能会破坏您的表，备份所有内容。
