【问题描述】：

我在Win 7 上安装了WAWMP。它运行良好，但自从我重新启动系统后，我遇到了问题。

问题是mysql 没有启动，但Apache 正常运行。当我 Test Port 80 它说 Apache 正在运行。

我已尝试更改 my.ini 或 MySQL 中的端口，但 MySQL 仍然无法启动。

这是我尝试启动MySQL时的最新日志

【问题讨论】：

它们似乎是您的文件损坏。您是否在长时间导入期间关闭了 WAMP？

XAMPP/MySQL: could not open single-table tablespace file .\mysql\innodb_index_stats.ibd after restart of MySQL 的可能重复项

【参考方案1】：

尝试转到控制面板、管理工具、服务或运行 services.msc（快捷方式）尝试启动和停止并重新启动 MYSQL 服务。

【参考方案2】：

好的，我通过删除C:\WAMP\mysql\data 中的ibdata1 文件解决了我的问题

对于那些不知道What is stored in ibdata1是什么的人
