Mysql启动失败报错1067
Mysql装好后,重启电脑第二次发现服务无法启动。提示如下:
------------------------
MySQL 服务无法启动。
系统出错。
发生系统错误 1067。
进程意外终止。
------------------
查看了F:/ProgramData/MySQL/MySQL Server 5.5/data 这个目录中的错误日志,显示如下内容:
130825 20:47:50 [Note] Plugin 'FEDERATED' is disabled.
130825 20:47:50 InnoDB: The InnoDB memory heap is disabled
130825 20:47:50 InnoDB: Mutexes and rw_locks use Windows interlocked functions
130825 20:47:50 InnoDB: Compressed tables use zlib 1.2.3
130825 20:47:50 InnoDB: Error: unable to create temporary file; errno: 2
130825 20:47:50 [ERROR] Plugin 'InnoDB' init function returned error.
130825 20:47:50 [ERROR] Plugin 'InnoDB' registration as a STORAGE ENGINE failed.
130825 20:47:50 [ERROR] Unknown/unsupported storage engine: INNODB
130825 20:47:50 [ERROR] Aborting
其中核心提示是这句,临时文件无法创建:
130825 20:47:50 InnoDB: Error: unable to create temporary file; errno: 2
因此查看my.ini
[mysqld]区段内加入:
#自己指定的临时文件目录
tmpdir="临时目录"
---------------------
原因是我安装好系统后,修改了系统临时目录的配置,将其指向了一个ramdisk的分区(内存分区盘),这个分区在关机后数据会消失。
而只有在mysql安装的时候,系统会自动创建这个临时文件目录,所以刚安装好后能够正常启动数据库。重启后(ramdisk的分区)目录就不存在了,而Mysql在启动服务的时候并不会再去创建这个临时文件目录,所以就报错了。

Local fine-tuning of DeepSeek class models faces the challenge of insufficient computing resources and expertise. To address these challenges, the following strategies can be adopted: Model quantization: convert model parameters into low-precision integers, reducing memory footprint. Use smaller models: Select a pretrained model with smaller parameters for easier local fine-tuning. Data selection and preprocessing: Select high-quality data and perform appropriate preprocessing to avoid poor data quality affecting model effectiveness. Batch training: For large data sets, load data in batches for training to avoid memory overflow. Acceleration with GPU: Use independent graphics cards to accelerate the training process and shorten the training time.
