![连接数据库报错的子错误[ERROR 1819 (HY000): Your password does not satisfy the current policy requirements]](http://www.mshxw.com/aiimages/31/281717.png "连接数据库报错的子错误[ERROR 1819 (HY000): Your password does not satisfy the current policy requirements]")
产生的原因：
自定义密码太简单，出现了不符合密码策略的问题.
1.查询mysql初始密码：SHOW VARIABLES LIKE 'validate_password%';
2.修改策略，及密码长度：set global validate_password_policy=0； set global validate_password_length=1;
3.修改密码:ALTER USER 'root'@'localhost' IDENTIFIED BY '123456';
(123456就是新密码，可以自由定义)
