2024-04-24 01:33:06

mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'root' WITH GRANT OPTION;
ERROR 1819 (HY000): Your password does not satisfy the current policy requiremen
这是由于mysql密码强度的设置规则导致的。
- 查看mysql全局的密码相关的参数
mysql> SHOW VARIABLES LIKE 'validate_password%';
+--------------------------------------+--------+
| Variable_name | Value |
+--------------------------------------+--------+
| 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 |
+--------------------------------------+--------+
6 rows in set (0.08 sec)
参数解释
| 相关参数 | 解释 |
|---|---|
| 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，参数默认为8，它有最小值的限制，最小值为：validate_password_number_count + validate_password_special_char_count + (2 * validate_password_mixed_case_count) |
| 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。 |
密码强度等级解释：
| 密码强度 | 解释 |
|---|---|
| 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 |
修改mysql参数：
mysql> set global validate_password_policy=0;
Query OK, 0 rows affected (0.05 sec) mysql>
mysql>
mysql> set global validate_password_mixed_case_count=0;
Query OK, 0 rows affected (0.00 sec) mysql> set global validate_password_number_count=3;
Query OK, 0 rows affected (0.00 sec) mysql> set global validate_password_special_char_count=0;
Query OK, 0 rows affected (0.00 sec) mysql> set global validate_password_length=3;
Query OK, 0 rows affected (0.00 sec) mysql> SHOW VARIABLES LIKE 'validate_password%';
+--------------------------------------+-------+
| Variable_name | Value |
+--------------------------------------+-------+
| validate_password_dictionary_file | |
| validate_password_length | 3 |
| validate_password_mixed_case_count | 0 |
| validate_password_number_count | 3 |
| validate_password_policy | LOW |
| validate_password_special_char_count | 0 |
+--------------------------------------+-------+
6 rows in set (0.00 sec)
