mysql 安装完不好执行语句。ERROR 1820 (HY000): You must reset your password using ALTER USER statement before e

ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement.

参考自:https://dev.mysql.com/doc/refman/5.7/en/alter-user.html

需要用ALTER USER重置一次密码才能执行sql语句，

ALTER USER 'root'@'localhost' IDENTIFIED BY '新密码' PASSWORD EXPIRE NEVER;	-- 密码永不过期

ALTER USER 'root'@'localhost' IDENTIFIED BY '新密码

' PASSWORD EXPIRE; -- 密码有过期时间
