MySQL报错“ERROR 1819 (HY000): Your password does not satisfy the current policy requirements”
解决办法:
- 查看 mysql 初始的密码策略。
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)
- 设置密码验证强度等级,将MEDIUM设置为LOW。
mysql> set global validate_password_policy=LOW; Query OK, 0 rows affected (0.00 sec)
- 修改密码默认长度为6
mysql> set global validate_password_length=6; Query OK, 0 rows affected (0.01 sec)
现在只要满足六位的长度的简单密码即可设置
ALTER USER 'root'@'localhost' IDENTIFIED BY '123456';
- 关于 mysql 密码策略相关参数;
- validate_password_length 固定密码的总长度;
- validate_password_dictionary_file 指定密码验证的文件路径;
- validate_password_mixed_case_count 整个密码中至少要包含大/小写字母的总个数;
- validate_password_number_count 整个密码中至少要包含阿拉伯数字的个数;
- validate_password_policy 指定密码的强度验证等级,默认为 MEDIUM;
- 关于 validate_password_policy 的取值:
0/LOW:只验证长度; 1/MEDIUM:验证长度、数字、大小写、特殊字符; 2/STRONG:验证长度、数字、大小写、特殊字符、字典文件;
- validate_password_special_char_count 整个密码中至少要包含特殊字符的个数。
