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?

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

进入xampp/mysql/data目录

将文件夹data重命名为data_backup 创建新文件夹数据从备份文件复制到数据从数据文件夹中删除ibdata1 将ibdata1从data_backup文件夹拷贝到data文件夹将所有数据库从data_backup复制到data文件夹重启xampp。它会开始工作

There are a number of things I've tried. This is the 2nd time this has happened to me. On my first time, I've to reinstall my xampp. And on the third day, mysql crashed again. I've tried everything I found on the internet. Like, innodb_flush_method=normal in my.ini file and deleting ibdata1, ib_logfile1, ib_logfile0 files, and others but none of these works. So later I tried to run xampp with admin privilege and install apache and mysql as a service as it was instructed on xampp control panel itself. After starting mysql, I read error-log again and from there I came to know that one of my databases is responsible for this. That database file won't let mysql start. So I deleted everything in the data folder and then in cmd I navigated to C:/xampp/mysql/bin path and ran these commands:

mysqld——初始化

mysql_install_db

mysql又开始运行了。但是我的数据库和数据丢失了。

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。

这是更精确的答案，对我来说很管用!!!!！一个更干净的方法是恢复整个/mysql/data/文件夹。Windows有内置的文件夹版本控制-右键单击/mysql/data/并选择恢复以前的版本。然后可以删除文件夹的当前内容，并将其替换为旧版本的内容。正如Ryan Williams所提到的。
