解决电脑死机导致的xampp无法启动mysql

电脑死机重启后,再开机打开xamppmysql就无法启动了。

xampp上的错误日志

09:41:15  [mysql]   Error: MySQL shutdown unexpectedly.
09:41:15  [mysql]   This may be due to a blocked port, missing dependencies, 
09:41:15  [mysql]   improper privileges, a crash, or a shutdown by another method.
09:41:15  [mysql]   Press the Logs button to view error logs and check
09:41:15  [mysql]   the Windows Event Viewer for more clues
09:41:15  [mysql]   If you need more help, copy and post this
09:41:15  [mysql]   entire log window on the forums

大概意思是mysql启动失败,提示可能是端口被占用,缺少依赖,权限问题,电脑死机或者其他任何导致关机都可能是原因,等于啥都没说,端口确认是没有占用的,我这个情况显然是因为之前的电脑死机导致的。

提示查看错误日志。下面查看mysql的启动错误日志。

从这上面看不出来到底哪里报错了,没有什么大问题。

进入到xampp下的mysqlbin文件夹,我这边是D:\xampp72\mysql\bin运行mysqld --console

通过mysqld –console的输出来查看

看到很多类似的错误信息:

mysqld --console错误消息

尝试解决

经过删除上面的那些看上去像临时文件的尝试(先备份),最后发现,需要删除你的xampp目录mysql/data文件夹里与下图类似命名的文件就可以正常启动mysql了。

我的目录是D:\xampp72\mysql\data,图中打马赛克的是计算机名称。
