mysql授权报错 ERROR 1819 (HY000): Your password does not satisfy the current policy requirements

 授权用户时报错，ERROR 1819 (HY000): Your password does not satisfy the current policy requirements

原因为其实与validate_password_policy的值有关

mysql> SHOW VARIABLES LIKE 'validate_password%';
+--------------------------------------+--------+
| Variable_name                        | Value  |
+--------------------------------------+--------+
| validate_password_check_user_name    | OFF    |
| validate_password_dictionary_file    |        |
| validate_password_length             | 8      |
| validate_password_mixed_case_count   | 1      |
| validate_password_number_count       | 1      |
| validate_password_policy             | MEDIUM |
| validate_password_special_char_count | 1      |
+--------------------------------------+--------+
7 rows in set (0.00 sec)

发现validate_password_policy为MEDIUM

参数说明

validate-password=ON/OFF/FORCE/FORCE_PLUS_PERMANENT: 决定是否使用该插件(及强制/永久强制使用)。

validate_password_dictionary_file：插件用于验证密码强度的字典文件路径。

validate_password_length：密码最小长度。

validate_password_mixed_case_count：密码至少要包含的小写字母个数和大写字母个数。

validate_password_number_count：密码至少要包含的数字个数。

validate_password_policy：密码强度检查等级，0/LOW、1/MEDIUM、2/STRONG。

validate_password_special_char_count：密码至少要包含的特殊字符数。

关于validate_password_policy-密码强度检查等级：

执行以下操作就可以了

mysql>     set global validate_password_policy=0;  
Query OK, 0 rows affected (0.00 sec)

mysql> show global variables like "validate_password_policy";
+--------------------------+-------+
| Variable_name            | Value |
+--------------------------+-------+
| validate_password_policy | LOW   |
+--------------------------+-------+
1 row in set (0.01 sec)
