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。

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

我也有同样的问题。我的xampp控制面板将启动apache而不是mysql。问题出在iblogfile中。当你正在运行xampp/mysql时，你的电脑重新启动，而没有正确关闭innodb引擎。进入xampp/mysql并删除

ib_logfile0

and

ib_logfile1

现在重新启动mysql，它应该工作。

其他回答

我也遇到过这个问题，我是这样解决的。 1. 确保xampp不在子目录下。例如，它应该是C:\xampp 2. 在运行应用程序时，您可能需要以管理员身份运行。

希望这能起作用!

去:c: c: \xampp\mysql

将文件夹“data”重命名为“data_old”(可以使用任何名称) 创建新文件夹data 拷贝“backup”文件夹的内容到新的“data”文件夹中。 ***复制“data_old”的所有内容到“data”(跳过那些文件夹“mysql”，“performance_schema”和“phpmyadmin”)** *，而不替换目标文件(跳过这些文件)**

重启XAMPP 这是可行的

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
