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?

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

taskkill /PID 8120 /F

重新启动MySQL。会没事的。快乐的绳索。

其他回答

重命名mysql/data中的以下文件 ib_logfile0 ib_logfile1 ibdata1

my.cnf innodb_buffer_pool_size到200M根据你的ram innodb_log_buffer_size为32M

重新启动apache服务器

希望对你有所帮助

下面是解决这个问题的方法:

打开C:\xampp\mysql\data 您将看到一个名为mysql/data的文件夹将该文件夹从mysql/data重命名为mysql/data_not_useful任何你想给的名字。创建一个名为mysql/data的新文件夹。复制mysql/backup的所有文件，粘贴mysql/data。现在转到mysql/data_not_useful并从那里复制文件ibdata1。然后粘贴到mysql/data(你必须替换文件)。重新启动xampp服务器。现在运行你的mysql服务器。

移动xampp/mysql/backup文件到xampp/mysql/data 以管理员身份运行XAMPP(确保mysql已经安装，如果已经安装可以看到一个绿色的勾)

希望能有所帮助!

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。
