设置有关于密码的东西时密码很简单产生错误

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

查看 mysql 初始的密码策略

SHOW VARIABLES LIKE ‘validate_password%‘;

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

ERROR 1819 (HY000): Your password does not satisfy the current policy requirements
