删除mysql安装主目录下的data目录下所有文件

mysqld --initialize --console

C:\WINDOWS\system32> mysqld --initizlize --console
mysqld: Can't change dir to 'D:\Program Files\mysql-8.0.12-winx64\data\' (OS errno 2 - No such file or directory)

如上述报错的话，加上user，并记录初始密码

mysqld --initialize --user=root --console

C:\WINDOWS\system32>mysqld --initialize --user=root --console

如登陆不上，需要运行net stop mysql,

然后重新运行下mysqld --initialize --user=root --console

mysql -u root -p

mysql执行语句一定要以;结尾。切记。

mysql>  ALTER USER 'root'@'localhost' IDENTIFIED BY 'fjdoe13232
