【mysql初始设置密码报错处理方法】ERROR 1819 (HY000): Your password does not satisfy the current policy requirements

直译报错：您的密码不符合当前的政策要求（密码初始验证策略要求）

查看mysql初始密码验证策略：

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)   变量定义： 1、validate_password_check_user_name：验证密码检查用户名，非必须 2、validate_password_dictionary_file：验证密码字典文件，无要求 3、 validate_password_length：验证密码长度，8字符 4、validate_password_mixed_case_count：验证密码混合大小写，否 5、validate_password_policy：验证密码策略，中等 6、validate_password_special_char_count：验证密码特殊字符数，否   报错其实与validate_password_policy的值有关，validate_password_policy有以下取值：

Policy	Tests Performe（要求）
0 or LOW	Length
1 or MEDIUM	numeric, lowercase/uppercase, and special characters
2 or STRONG	Length; numeric, lowercase/uppercase, and special characters

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。 解决办法： 简单2步即可解决，修改验证密码相关数据以支持简单密码设置： mysql> set global validate_password_length=6;                                                                                                                    Query OK, 0 rows affected (0.00 sec)                                                                                                                                                                                                                                                                                              mysql> set global validate_password_policy=0;                                                                                                                    Query OK, 0 rows affected (0.00 sec)                                                                                                                                                                                                                                                                                         mysql> set password for root@localhost = password(‘test123‘);                                                                                                    Query OK, 0 rows affected, 1 warning (0.01 sec) 设置密码成功。
