1 有环境变量可以省略这个

2 建用户并授权

GRANT ALL PRIVILEGES ON *.* TO user@localhost IDENTIFIED BY 'pwd' WITH GRANT OPTION;
GRANT ALL PRIVILEGES ON *.* TO user@'%' IDENTIFIED BY 'pwd' WITH GRANT OPTION;#话说密码里有\，执行这句的时候要在前边加\\,变成一共3个斜杠
FLUSH PRIVILEGES;

3建库删库

CREATE DATABASE test2 DEFAULT CHARACTER SET utf8 COLLATE utf8_bin;
DROP DATABASE test2;

mysqldump -uroot -proot dbname>D:\1.sql
