MySQL5.6.6版本之后增加了密码强度验证插件validate\_password，相关参数设置的较为严格。  
使用了该插件会检查设置的密码是否符合当前设置的强度规则，若不满足则拒绝设置。  
有时候，只是为了自己测试，不想密码设置得那么复杂，譬如说，我只想设置root的密码为123456。  
解决办法：

1.set global validate_password_policy=0;  
    /**密码强度检查等级，0/LOW、1/MEDIUM、2/STRONG。有以下取值：
    Policy                 Tests Performed                                                                                                        
    0 or LOW               Length                                                                                                                      
    1 or MEDIUM         Length; numeric, lowercase/uppercase, and special characters                             
    2 or STRONG        Length; numeric, lowercase/uppercase, and special characters; dictionary file      
    默认是1，即MEDIUM，所以刚开始设置的密码必须符合长度，且必须含有数字，小写或大写字母，特殊字符。现在我们一个一个消灭*/
    2. set global validate_password_mixed_case_count=0; //密码至少要包含的小写字母个数和大写字母个数清零
    3.  set global validate_password_number_count=3;  //密码至少要包含的数字个数为3
    4.set global validate_password_special_char_count=0;  //密码至少要包含的特殊字符数为0
    5.set global validate_password_length=3;  //密码最小长度为3
    6. SHOW VARIABLES LIKE 'validate_password%';  //查看密码策略
    可以发现所有烦人的限制都没了，现在，设置一个超简单的密码
    SET PASSWORD FOR 'root'@'localhost' = PASSWORD('123456');  
    
    终极解决办法：
    在/etc/my.cnf 中 的 [mysqld] 中增加如下的配置:
    
    validate_password=OFF
