如何解决“错误:MySQL关机意外”?

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。

12:19:12 PM [mysql] Attempting to start MySQL app... 12:19:12 PM [mysql] Status change detected: running 12:19:13 PM [mysql] Status change detected: stopped 12:19:13 PM [mysql] Error: MySQL shutdown unexpectedly. 12:19:13 PM [mysql] This may be due to a blocked port, missing dependencies, 12:19:13 PM [mysql] improper privileges, a crash, or a shutdown by another method 12:19:13 PM [mysql] Press the Logs button to view error logs and check 12:19:13 PM [mysql] the Windows Event Viewer for more clues 12:19:13 PM [mysql] If you need more help, copy and post this 12:19:13 PM [mysql] entire log window on the forums

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?

简单的解决方案

重命名xampp\mysql\data文件夹中的以下文件

 ib_logfile0
 ib_logfile1

或任何这样的日志文件

 ib_logfile0.bak
 ib_logfile1.bak

现在从xampp控件启动mysql。

其他回答

在Xamp中打开MuSQL配置文件，修改端口号为3307 这对我很有用:)

Error: MySQL shutdown unexpectedly

This is the best answer 

1)Rename the folder mysql/data to mysql/data_old (you can use any name)
2)Create a new folder mysql/data
3)Copy the content that resides in mysql/backup to the new mysql/data folder
4)Copy all your database folders that are in mysql/data_old to mysql/data (skipping the mysql, performance_schema, and phpmyadmin folders from data_old)
5)Finally copy the ibdata1 file from mysql/data_old and replace it inside mysql/data folder
6)Start MySQL from XAMPP control panel

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:

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!

我尝试了上面所有的答案，但对我来说都不管用。所以最后我尝试了下面的方法，它100%适合我。

如果您担心无法执行以下步骤，为安全起见，您可以对整个XAMPP文件夹进行备份。

第一步:将c:\xampp\mysql\data文件夹重命名为c:\xampp\mysql\data_bkp

新建文件夹c:\xampp\mysql\data。

第三步:复制c:\xampp\mysql\backup中的内容到新的c:\xampp\mysql\data文件夹中。

第四步:复制所有数据库文件夹c:\xampp\mysql\data_bkp到c:\xampp\mysql\data(注意:不要复制mysql、performance_schema和phpmyadmin文件夹)。

步骤5:从c:\xampp\mysql\data_bkp复制ibdata1文件，并将其替换到c:\xampp\mysql\data文件夹中。

步骤6:从XAMPP控制面板启动MySQL。
