打开cmd：mysql -uroot -p 

进入mysql依次执行下面语句

ALTER USER 'root'@'localhost' IDENTIFIED BY 'password' PASSWORD EXPIRE NEVER; #修改加密规则 

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'root'; #更新一下用户的密码 

FLUSH PRIVILEGES;　　 #刷新权限

alter user 'root'@'localhost' identified by 'xzx123456';　　#重置密码，xzx123456就是变更后的密码，自己的密码自己更改下哦

每条命令后边的';'别忘了加
