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

操作数据库时提示ERROR 1819 (HY000): Your password does not satisfy the current policy requirements问题。
原因是因为Mysql增加了密码强度验证插件：validate_password，去网上查原因都是是因为设置的密码太简单了，才会出现这个问题，但是我设置的挺复杂的，莫名其妙(｀・ω・´)

解决办法：
进入到mysql，依次输入一下命令即可解决：

mysql> SHOW VARIABLES LIKE ‘validate_password%’;
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '‘validate_password%’' at line 1
