腾讯云mysql提示ALTER USER修改密码以及 Your password does not satisfy the current policy requirements

1、You must reset your password using ALTER USER statement before executing this statement.
在执行此语句之前，必须使用ALTER USER语句重置密码。

（1）、 修改用户密码

mysql> alter user 'root'@'localhost' identified by 'youpassword';  

或者

mysql> set password=password("youpassword");

（2）、刷新权限

mysql> flush privileges;

Your password does not satisfy the current policy requirements
您的密码不符合当前的策略要求

注意：如果只想设置简单密码需要修改两个全局参数：

mysql> set global validate_password_policy=0;
mysql> set global validate_password_length=1;

mysql> SET PASSWORD = PASSWORD('123456'); //123456 是重置的新密码
