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:

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?

为此，您需要单击Modules Services下的x选项，并安装MYSQL服务。然后启动服务。给你。

其他回答

从C:\xampp\mysql创建一个备份你的mysql文件夹。然后转到C:\xampp\mysql\backup复制所有文件并粘贴到C:\xampp\mysql\data中。

然后从你的旧备份文件夹中找到ibdata1文件，你可以在C:\xampp\mysql\data中找到它。复制此文件并粘贴到C:\xampp\mysql\data中。

现在重新启动xampp，它应该工作了。

以上的解决方案没有一个是无效的。它只是暂时有效。几天后，我们又一次面对同样的问题。我每次都失去了所有的脑起搏器。

我不知道确切的答案。但是，我一遍又一遍地做这3个简单的步骤。

将文件夹c:\xampp\mysql\data重命名为c:\xampp\mysql\data_old(可以使用任何名称)。新建data文件夹c:\xampp\mysql\data 复制mysql\data_old中的所有数据库文件夹到mysql\data中

然后从XAMPP控制面板启动MySQL。

解决了!我用这个方法来解决它:

从控制面板打开shell并启动mysql:

mysqld –-console –-skip-grant-tables –-skip-external-locking

从控制面板打开另一个shell，用下面的命令修复数据库:

mysqlcheck -r --databases mysql --use-frm

停止mysql，关闭shell，正常重启mysql。

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.

我也有同样的问题。溶液是杀灭过程查找端口(3306)的PID

netstat -a -n -o | find "3306"

你会看到你需要的一切。

0.0.0.0:3306           0.0.0.0:0              LISTENING       8120   TCP    
0.0.0.0:33060          0.0.0.0:0              LISTENING       8120   TCP    
[::]:3306              [::]:0                 LISTENING  8120   TCP    
[::]:33060             [::]:0                 LISTENING  8120

PID为8120

执行如下命令

taskkill /PID 8120 /F

重新启动MySQL。会没事的。快乐的绳索。
