请设置满足7条MySql验证规则的密码

例如：- d_VX>N（“xn_BrD2y

让验证标准更简单一点可以解决这个问题

SET GLOBAL validate_password_length = 6;
SET GLOBAL validate_password_number_count = 0;

但建议使用强密码是正确的解决方案

在我的例子中，当有一个错误的引用时，错误就出现了:

GRANT所有database_name。* ' user1 ' @'8.10.12.2';(用户名周围的单引号错误)

vs

GRANT所有database_name。* 'user1'@'8.10.12.2';(正确)

如果你想设置一个空白密码。然后在MySQL客户端运行以下查询:

SET GLOBAL validate_password.check_user_name = No;
SET GLOBAL validate_password.dictionary_file = '';
SET GLOBAL validate_password.length = 0;
SET GLOBAL validate_password.mixed_case_count = 0;
SET GLOBAL validate_password.number_count = 0;
SET GLOBAL validate_password.policy = LOW;
SET GLOBAL validate_password.special_char_count = 0;

输出应该是这样的:

    SHOW VARIABLES LIKE 'validate_password%';

+--------------------------------------+-------+
| Variable_name                        | Value |
+--------------------------------------+-------+
| validate_password.check_user_name    | ON    |
| validate_password.dictionary_file    |       |
| validate_password.length             | 0     |
| validate_password.mixed_case_count   | 0     |
| validate_password.number_count       | 0     |
| validate_password.policy             | LOW   |
| validate_password.special_char_count | 0     |
+--------------------------------------+-------+

然后，您可以使用以下查询更新您的空白密码:

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '';

对于MySQL 8，你可以使用下面的脚本:

SET GLOBAL validate_password.LENGTH = 4;
SET GLOBAL validate_password.policy = 0;
SET GLOBAL validate_password.mixed_case_count = 0;
SET GLOBAL validate_password.number_count = 0;
SET GLOBAL validate_password.special_char_count = 0;
SET GLOBAL validate_password.check_user_name = 0;
ALTER USER 'user'@'localhost' IDENTIFIED BY 'pass';
FLUSH PRIVILEGES;

SHOW VARIABLES LIKE 'validate_password%';

mysql> SET GLOBAL validate_password.length = 6;
mysql> SET GLOBAL validate_password.number_count = 0;
mysql> SET GLOBAL validate_password.policy=LOW;
SHOW VARIABLES LIKE 'validate_password%';

对我来说，在ubuntu新安装的mysqld上不起作用，必须添加这个:到/etc/mysql/mysql.conf.d/mysqld.cnf，否则服务器不会启动(猜测插件没有在正确的时间加载，当我只是添加它而没有plugin-load-add指令时)

plugin-load-add=validate_password.so
validate_password_policy=LOW
validate_password_length=8
validate_password_mixed_case_count=0
validate_password_number_count=0
validate_password_special_char_count=0
