Question

我需要在xampp 3.2.1中对MySql提供一些帮助。 MySql服务无法启动，我找不到原因，因为错误日志文件报告它无法从“未知文件”读取并且仅返回错误0。我不知道这意味着什么，因为它基本上说它在尝试读取未知文件时有0错误。这是错误日志：

请帮助。

Answer 1

这是针对不同的错误代码，但看看它是否有效。

通过“Config”打开MySQL配置文件 - ＆gt; “的my.ini”。

插入 innodb_flush_method = normal

之间 innodb_lock_wait_timeout = 50和## UTF 8 Settings

在xampp中再次启动MySQL。

我遇到了完全相同的问题 - 运行相同版本的XAMPP，它刚刚开始与您的问题同时发生。

试试这个。打开XAMPP目录并转到XAMPP / mysql / Data

剪切所有文件（ibdata *，auto.cnf，mysql.pid）并将它们放在其他地方。

尝试启动Mysql - 如果效果很好，如果没有，你可能需要做的是，在你的日志中查找DB给你一个问题 - 并移动相应的文件夹。

幸运的是，这将解决你的问题 - 这对我有用！
