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?

当前回答

简单的解决方案从Xampp控制面板打开外壳

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

然后再次打开另一个shell并运行

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

现在关闭两个shell并重新启动xampp。

其他回答

我的Xampp MySQL工作如下:

01.Go to mysql/data/ directory
02. delete the ibdata1 & ib_logfile*(ib_logfile0,ib_logfile1,ib_logfile101) file
03. restart xampp server

我解决了!在安装xampp之前用msconfig禁用UAC

我解决了类似的MySQL错误&我认为这个答案将帮助您修复相同类型的MySQL数据库错误。

解决方案:

进入mysql数据库的“data”目录。我安装XAMPP在D:驱动器上的计算机和mysql的“数据”目录位置我的计算机是“D:\ XAMPP \mysql\data\”。你可能有不同的位置。

取备份MySQL“data”文件夹

首先，你应该创建一个备份的“数据”文件夹使用任何压缩软件。给出一个像“data_backup.zip”这样的名称或任何您希望的压缩类型。我使用winrar压缩软件压缩备份mysql“data”文件夹。

重命名data文件夹

重命名" data "文件夹为" data-oldfiles "。将数据目录重命名为任何新的目录名称是非常重要的。

创建一个新的“data”文件夹

创建一个新文件夹，命名为data 为了解决这个问题，我们需要在mysql数据库中创建一个新的“data”目录。

从“备份”文件夹复制内容

进入“备份”文件夹，复制所有文件。将备份文件夹中的文件粘贴到数据文件夹中现在从XAMPP启动MySQL数据库。您的MySQL数据库将正常启动，不会显示任何错误。

传输所有MySQL项目的数据库、数据文件和日志文件

If you have many database which was used for various projects, then you have to transfer all database from “data-oldfiles” folder to “data” folder. Copy all databases from the data-old files and paste to the data folder. Now you have to copy the data file “ibdata1” & all log files “ib_logfile0, ib_logfile1 ” from data-old files folder to the data folder. If you have many id_logiles then copied all of them. Now Start MySQL from XAMPP. Go to phpMyAdmin to check all databases are available & working. Now start your any website project from localhost to check the MySQL database.

问题解决了!!

现在，您将看到问题已经解决，错误消息“error: MySQL shutdown unexpected .”不会再出现。如果你对这个问题有任何疑问，请在评论区提出任何问题。

Apache - >配置- >打开httpd . conf。搜索监听或80，更新监听端口到8081保存并重新启动服务器。哦，如果你有Skype，关掉它。

上述解决方案对我来说都没用。然后我做了以下事情:

我删除了C:\xampp\mysql\data\目录下的所有文件，除了这个目录下的文件夹。它工作得非常好，但我以前的数据库现在不能工作了。所以，如果你不关心，上面会删除所有你以前的数据库在phpmyadmin。
