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?

当前回答

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。

其他回答

如果崩溃信息是“mysql.exe已停止工作”。以管理员身份运行xampp-control.exe将立即解决您的问题。

# The MySQL server
default-character-set=utf8mb4
[mysqld]
skip-grant-tables // Place this line here 
port=3306
socket="C:/xampp/mysql/mysql.sock"
basedir="C:/xampp/mysql"
tmpdir="C:/xampp/tmp"
datadir="C:/xampp/mysql/data"
pid_file="mysql.pid"
# enable-named-pipe
key_buffer=16M
max_allowed_packet=1M
sort_buffer_size=512K
net_buffer_length=8K
read_buffer_size=256K

打开C:\xampp\mysql\data中的my.ini文件

Skip-grant-tables将这一行放在端口和重新启动之前，它可以工作

四月更新(2022年)

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

我打开并清空存在于数据文件夹中的文件multi-master.info。这对我很管用。

转到任务管理器，结束正在运行的MySQL任务，并在XAMPP中重新启动MySQL
