Question

Xampp mysql phpmyadmin几天前运行得很好。现在我遇到了这个问题。

我尝试更改端口号，但我仍遇到此问题

Windows错误提示告诉我：

我也尝试过这样做对某些有同样问题的人有效

我打开了错误日志，但我似乎无法理解它的内容。

我还遇到了一个解决方案，它正在再次更改与skype冲突的端口。但我没有在我的电脑上安装skype

XAMPP - Error: MySQL shutdown unexpectedly

我还尝试使用NetStat检查我的默认mysql端口3306是否正在使用，但它提到没有服务使用该端口。

感谢您的帮助。

Answer 1

当我的错误没有在mysql中运行时 InnoDB：警告：使用innodb_additional_mem_pool_size是DEPRECATED。在将来的版本中可以删除此选项，以及选项innodb_use_sys_malloc和InnoDB的内部内存分配器。 2015-11-10 15:26:56 4348 [注意] InnoDB：使用互斥量来引用缓冲池页面

解决方案：删除ibdata1，all（ib_logfile）...并重启xampp

Answer 2

您自己的关联SO页面有答案。从您的错误日志：

2014-08-27 09:12:23 3296 [注意] InnoDB： ibdata 文件中的日志序列号1625987和1625987与日志序列号不匹配在ib_logfiles中的3459249！

然后，来自XAMPP - MySQL shutdown unexpectedly

中评分最高的答案

退出Xampp服务器

转到您的C：\ xampp \ mysql \ data目录

删除ibdata1文件

重新启动xampp服务器

尝试一下，你应该打败它。

Answer 3

我有同样的问题。不幸的是，上述解决方案对我没有用。我已经通过删除ib_logfile0，ib_logfile1 ...解决了所有日志文件，而我的xampp现在可以正常工作了！根据上述解决方案，如果我删除ibdata1文件，则所有数据库都丢失了。因此，我保留了ibdata1文件并删除了所有日志文件。
