有的时候因为掉电或者其他原因导致数据库损坏,我们可以使用mysql自带的mysqlcheck命令来快速修复所有的数据库或者特定的数据库;例如检查优化并修复所有的数据库用:
1.先在运行中输入CMD,启动命令行.
2.进入Mysql的Bin目录:E:\Program Files\MySQL\MySQL Server 5.0\bin,如果不知道如何进入别的目录,就要参考网上的资料补习基础知识了.
常见方式:
运行 E:
运行 CD "E:\Program Files\MySQL\MySQL Server 5.0\bin"
3.运行:mysqlcheck -A -o -r -uroot -p888888
注意,将888888改成你自己的root用户密码
mysql.columns_priv OK
mysql.db OK
mysql.func OK
mysql.help_category OK
mysql.help_keyword OK
mysql.help_relation OK
mysql.help_topic OK
mysql.host OK
mysql.tables_priv OK
mysql.time_zone OK
mysql.time_zone_leap_second OK
mysql.time_zone_name OK
mysql.time_zone_transition OK
mysql.time_zone_transition_type OK
mysql.user OK
......

注意!
在修复过程中,如果看到有error的提示,表明这个表是坏的,无法修复的,对于含有坏表的的mysql数据库,您只能删除它,或停止它,不然会影响整个Mysql的稳定,造成mysql自动停止.(提示"The storage engine for the table doesn't support repair"的表不需要处理)
如果修复太快看不到结果,可以运行
mysqlcheck -A -o -r -uroot -p888888 >>C:\test.txt
运行后打开test.txt就可以看到了.
