当我打开XAMPP并单击启动MySQL按钮时,它给了我一个错误。 我刚才启动了它,但现在它不工作了。

以下是错误日志的内容:

最重要的错误信息在这里:

日志的其余部分:

InnoDB: Error: could not open single-table tablespace file .\xat\payments.ibd InnoDB: We do not continue the crash recovery, because the table may become InnoDB: corrupt if we cannot apply the log records in the InnoDB log to it.

InnoDB: 3) If the file system or the disk is broken, and you cannot remove InnoDB: the .ibd file, you can set innodb_force_recovery > 0 in my.cnf InnoDB: and force InnoDB to continue crash recovery here.

这些错误的原因是什么?我该如何纠正它们?


当前回答

也有同样的问题。

STAEP 1

backup folder xampp/mysql/data (saved it as `xampp/mysql/_old_data`).

STAEP 2

去xampp/mysql/data,删除所有的文件,但没有文件夹!与数据库。

STAEP 3

At this stage your database will not work. You need to go to your backup folder `xampp/mysql/_old_data` and copy over "`ibdata1`" file to `xampp/mysql/data`.

之后,一切工作如预期,包括phpmyadmin和控制台。

STAEP 4

如果这没有帮助的话。可以删除xampp/mysql/data文件夹,并将xampp/mysql/_old_data重命名为xampp/mysql/data。 (ROLLBACK)尝试不同的东西。

其他回答

如果这里列出的解决方案都不适合你和我一样,那么

进入任务管理器。 进入“服务”选项卡。 查找名为“MySQL80”的服务。 右键单击它并选择“stop”。 回到XAMPP控制面板,启动MySQL服务。

这对我很管用。

重要提示:不要删除ibdata1文件。你可以毁掉你所有的数据库。

相反,首先尝试使用XAMPP附带的MySQL备份文件夹。所以接下来的步骤:

将mysql/data文件夹重命名为mysql/data_old 复制mysql/backup文件夹,命名为mysql/data 将所有数据库文件夹从mysql/data_old复制到mysql/data(除了mysql, performance_schema和phpmyadmin文件夹) 将mysql/data_old/ibdata1文件拷贝到mysql/data文件夹中 从XAMPP控制面板启动MySQL

And,瞧!

编辑(2023年1月7日)

正如一些用户所提到的,这是一种紧急解决方案,而不是永久解决方案。在恢复数据后,强烈建议备份它,并重新安装XAMPP,因为失败与XAMPP的一些文件的故障有关,而不是数据库。

以下是我所做的。我重启了电脑。接下来运行services.msc。我停止MySQL服务,然后重新启动它。重新启动Xampp服务器。

如果以上任何一种方法都不起作用,制作Xampp目录的备份并重新安装Xampp。这当然有用!

伙计们,请确保你没有安装MySql服务器。因为我已经预装了MySql服务器,当我从xampp控制面板启动MySql时,一些端口冲突正在发生,它不工作。所以在从xampp控制面板启动mysql之前,请确保mysql服务器没有安装。我使用。net,所以我在过去安装了mysql服务器。卸载它解决了我的问题....
