解释: 由于valiadte_password
策略。密码强度需要非常高,所以有时候密码都无法成功修改。了解完下面变量就能解决了。
validate_password.policy
:密码策略,检查用户的密码。
0
:(Low)密码长度最少8个字符1
:(Mediumpolicy)至少包含1个数字,1个小写字母,1个大写字母和1个特殊字符组成(默认值)2
:(Strongpolicy)长度为4或更长的密码子字符串不得与字典文件中的单词匹配validate_password.length
:需要密码最小字符数,默认为8validate_password.number_count
:需要密码的最小数字字符数,默认为1validate_password.mixed_case_count
:需要密码的小写和大写的最小字符数,默认为1validate_password.special_char_count
:需要密码的特殊字符的最小字符数,默认为1validate_password.dictionary_file
:用于检查密码的字典文件的路径名,默认没有所以,如果出现报错:ERROR 1819 (HY000): Your password does not satisfy the current policy requirements,你可以:
Set Persist validate_password.policy = 0
只要你的密码长度不低于8个字符就行了,如果密码长度觉得还是长了,你可以:
Set Persist validate_password.length = 0
这样,你的长度是0,但注意,最小字符数不能低于以下表达式的值:
validate_password.number_count
+ validate_password.special_char_count
+ (2 * validate_password.mixed_case_count)
所以你的密码最小长度是4位,然后你可以直接查看:
mysql> Show Variables Like 'validate_password.%';
+--------------------------------------+-------+
| Variable_name | Value |
+--------------------------------------+-------+
| validate_password.check_user_name | ON |
| validate_password.dictionary_file | |
| validate_password.length | 4 | <-- 尽管你设置的是0,但最小还是4
| validate_password.mixed_case_count | 1 |
| validate_password.number_count | 1 |
| validate_password.policy | LOW |
| validate_password.special_char_count | 1 |
+--------------------------------------+-------+
7 rows in set (0.02 sec)
密码强度评估:1 ~ 100
mysql> select validate_password_strength('Password!'); +-----------------------------------------+ | validate_password_strength('Password!') | +-----------------------------------------+ | 50 | +-----------------------------------------+ 1 row in set (0.00 sec)
下面是官方的一段原话:英文好的可以看看
In MySQL 8.0.4, the validate_password plugin was reimplemented as the validate_password component. The validate_password plugin is deprecated and will be removed in a future version of MySQL. Consequently, its options are also deprecated and will be removed. MySQL installations that use the plugin should make the transition to using the component instead.
以上资料参考官方文档:6.4.3密码验证组件
