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:

2013-08-02 12:19:12 4536 [ERROR] InnoDB: 试图打开先前打开的表空间。 以前的表空间mysql/innodb_table_stats在filepath: .\mysql\innodb_table_stats.ibd使用的是空间ID: 1。 在文件路径:.\xat\payments.ibd下无法打开空间ID: 1的表空间xat/payments

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: To fix the problem and start mysqld: InnoDB: 1) If there is a permission problem in the file and mysqld cannot InnoDB: open the file, you should modify the permissions. InnoDB: 2) If the table is not needed, or you can restore it from a backup, InnoDB: then you can remove the .ibd file, and InnoDB will do a normal InnoDB: crash recovery and ignore that table. 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

打开C:\xampp\mysql\backup。

复制所有文件。

将它们粘贴到C:\xampp\mysql\data中。

如果Windows要求你替换某些文件,那就替换它们。

如果您的XAMPP控制窗格处于活动状态,请关闭它。

转到C:\xampp,找到xampp-control,运行它。

启动Apache,启动MySQL。


就是这样。

享受吧!

其他回答

我也有同样的问题。 我的xampp控制面板将启动apache而不是mysql。 问题出在iblogfile中。 当你正在运行xampp/mysql时,你的电脑重新启动,而没有正确关闭innodb引擎。 进入xampp/mysql并删除

ib_logfile0

and

ib_logfile1

现在重新启动mysql,它应该工作。

进入xampp/mysql/data目录

将文件夹data重命名为data_backup 创建新文件夹数据 从备份文件复制到数据 从数据文件夹中删除ibdata1 将ibdata1从data_backup文件夹拷贝到data文件夹 将所有数据库从data_backup复制到data文件夹 重启xampp。它会开始工作

打开C:\xampp\mysql\backup。

复制所有文件。

将它们粘贴到C:\xampp\mysql\data中。

如果Windows要求你替换某些文件,那就替换它们。

如果您的XAMPP控制窗格处于活动状态,请关闭它。

只需遵循两个步骤

进入xampp\mysql\backup 复制备份文件夹中的所有内容 转到xampp\mysql\data 粘贴所有从备份文件夹复制的数据文件夹 这一切。

也可以按照视频描述进行修复,而不会丢失任何数据:

或按照文章描述修复而不丢失任何数据:

我也遇到过同样的问题,但我所要做的就是关闭XAMPP控制面板,进入XAMPP安装的文件夹,找到XAMPP - Control .exe并以管理员身份运行,然后启动服务。
