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?

将mysql/data文件夹重命名为mysql/data_old 复制mysql/backup文件夹，命名为mysql/data 将所有数据库文件夹和mysql文件夹从mysql/data_old复制到mysql/data 将mysql/data_old/ibdata1文件拷贝到mysql/data文件夹中

从XAMPP控制面板启动MySQL

其他回答

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。

首先从控制面板进入配置

然后将mysql的端口编辑为8111

然后转到:my.ini文件 C: \ xampp \ mysql \ bin

并使端口从3306到8111，然后保存

然后进入控制面板，停止apache 然后尝试用我的SQL再次打开它，它将与我一起工作

我也面临着同样的问题，但上面提到的解决方案没有一个对我有帮助。我去了mysql配置文件(my.ini)，并更改了[mysqld]下的端口号。mysql默认运行在3306端口上。

port= 3306

我把它改成，

port= 8111

然后以管理员身份运行。最后这对我有用。

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。
