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?

当前回答

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

在mysql配置文件(my.ini)的[mysqld]部分下面添加以下一行，然后重新启动apache web服务器和mysql服务。

[mysqld]
innodb_force_recovery = 4

我也有这个问题，当我得到这个错误，去xampp->mysql->数据然后删除所有其他没有文件夹的文件，不要删除文件夹，然后运行xampp，启动mysql

永远不要删除这个文件(ibdata1)，因为您的所有数据都会被删除!! 我有三个建议:

答: 1-退出XAMPP控制面板。 1-重命名mysql/data文件夹为mysql/data_old(你可以使用任何名称) 创建一个新文件夹mysql/data 3-拷贝mysql/backup目录下的内容到新的mysql/data文件夹中拷贝mysql/data_old目录下的所有数据库文件夹到mysql/data目录下(跳过data_old目录下的mysql、performance_schema和phpmyadmin文件夹) 5-最后从mysql/data_old复制ibdata1文件，并将其替换到mysql/data文件夹中 6-重新启动系统。

B: 1-停止所有sql服务。 2-接下来，再次启动所有sql服务。

C: 1-打开XAMPP控制面板 2-点击Config按钮，在mysql前面，点击my.ini 3-更改客户端端口和服务器端端口。

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
