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:

2013-08-02 12:19:12 4536 [Note] Plugin 'FEDERATED' is disabled. 2013-08-02 12:19:12 f64 InnoDB: Warning: Using innodb_additional_mem_pool_size is DEPRECATED.

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?

遵循以下步骤:-

进入C:\xampp\mysql 重命名数据文件夹data_old 创建一个新文件夹空数据文件夹 复制data_old中的所有文件并将它们粘贴到data文件夹中 复制备份文件夹中的所有文件并粘贴到数据文件夹中,然后替换所有文件 从data_old复制ibdata1文件,并将它们粘贴并替换到data文件夹中。 重新启动服务器

祝一切顺利!!

其他回答

如果崩溃信息是“mysql.exe已停止工作”。以管理员身份运行xampp-control.exe将立即解决您的问题。

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:

我的Xampp MySQL工作如下:

01.Go to mysql/data/ directory
02. delete the ibdata1 & ib_logfile*(ib_logfile0,ib_logfile1,ib_logfile101) file
03. restart xampp server

我也面临着同样的问题,但上面提到的解决方案没有一个对我有帮助。 我去了mysql配置文件(my.ini),并更改了[mysqld]下的端口号。mysql默认运行在3306端口上。

port= 3306

我把它改成,

port= 8111

然后以管理员身份运行。最后这对我有用。

首先从控制面板进入配置

然后将mysql的端口编辑为8111

然后转到:my.ini文件 C: \ xampp \ mysql \ bin

并使端口从3306到8111,然后保存

然后进入控制面板,停止apache 然后尝试用我的SQL再次打开它,它将与我一起工作
