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。

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

如果这里列出的解决方案都不适合你和我一样,那么

进入任务管理器。 进入“服务”选项卡。 查找名为“MySQL80”的服务。 右键单击它并选择“stop”。 回到XAMPP控制面板,启动MySQL服务。

这对我很管用。

其他回答

如果没有一个文件的删除工作,那么可能你的mysql服务没有运行。 去做礼拜。启动mysql服务

# 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

记住永远不要删除这个文件(ibdata1),因为您的所有数据都会被删除

1-停止所有运行xampp服务(apache,mysql,..等)

2-重命名xampp文件夹为xampp-old

3-安装新xampp

4-通过从这个路径复制这3个文件(ibdata1,ib_logfile0,ib_logfile1) +您在xampp-old中创建的数据库文件夹来恢复数据库

mysql xampp-old \ \数据

to

xampp mysql \ \数据

并接受替换文件

5-通过将xampp-old\htdocs传输到xampp\htdocs恢复编码文件

现在启动xampp,它将处理您的所有数据

注意:如果您需要编辑apache或mysql ini,请再次执行此操作

尝试以下解决方案来解决这个问题。在执行此过程之前,将数据文件夹C:\xampp\mysql\data重命名为old_data。 然后在SQL文件夹中创建一个名为data的新文件夹。 将备份C:\xampp\mysql\backup文件夹中的所有文件和文件夹复制到data文件夹中。 在最后一步中,从old_data文件夹复制ibdata1文件和test文件夹,并将其放入data文件夹中。 现在运行程序并享受吧!

当您已经使用3306端口时就会发生这种情况。只要改变服务器端口,问题就会解决。
