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?

first of all, make a backup file of your database C:\xampp\mysql\data copy this file and past it somewhere in your pc. After this open, the data file and also open the XAMPP server try to delete the files step by step one by one after deleting each file try to run the MySQL server after deleting a single file as shown in the screenshot thus your databases won't delete. if the file deletion does not work then try to copy the same files from the backup folders and repeat this until it works... this is time taking but this worked for me I have solved this in 20 minutes.

其他回答

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....

解决方案:遵循下面列出的步骤。

步骤1。将文件夹c:\xampp\mysql\data重命名为c:\xampp\mysql\data_bkp(可以使用任何名称)。

步骤2。新建文件夹c:\xampp\mysql\data。

步骤3。复制mysql\backup中的内容到新的mysql\data文件夹中。

步骤4。将mysql\data_bkp中的所有数据库文件夹复制到mysql\data中(跳过mysql\data_bkp中的mysql、performance_schema和phpmyadmin文件夹)。 IMPORTATN注意:-请不要替换现有的文件,同时粘贴(点击跳过这些文件)

第5步。最后从mysql\data_bkp复制ibdata1文件,并将其替换到mysql\data文件夹中。

步骤6。从XAMPP控制面板启动MySQL。

而且,它已经完成了。没有数据库丢失,没有端口更改,没有以管理员身份运行,没有强制恢复,没有杀死mysqld进程,没有从以前的版本恢复,没有更多的错误。

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。

进入任务管理器 然后搜索mysqld,右键单击并选择END TASK并刷新XAMPP
