我想在MySQL中创建一个新用户，语法如下:
create user 'demo'@'localhost' identified by 'password';
但是它会返回一个错误:
您的密码不符合当前策略要求。
我试过很多密码，但都没用。我该如何解决这个问题?

this information is important to all answers above : When you restart mysql server all policy config will be RESET and will be LOST, so to make your policy configuration PERSISTENT, you should follow these instructions: (tested on ubuntu server version 20.10)
用mysql应用这些变化后，洪阮回答 Sudo nano /etc/mysql/mysql.conf.d/mysqld.cnf 加上最后一行:
[mysqld]
#
# * Basic Settings
#
..
..
..
validate_password.policy = LOW # <== this line
..
..
# IMPORTANT notes:
# - you can add more policy commands each by your needs.
# - notice the "." before "policy" , in some mysql versions is "_" , so be aware of that.
保存文件并重新启动mysql server: sudo service mysql restart 连接并检查配置的持久性: Sudo mysql -u your_username -p 显示像"validate_pass%"这样的变量; 结果应该是这样的:
+--------------------------------------+-------+
| Variable_name | Value |
+--------------------------------------+-------+
| validate_password.check_user_name | ON |
| validate_password.dictionary_file | |
| validate_password.length | 6 |
| validate_password.mixed_case_count | 1 |
| validate_password.number_count | 0 |
| validate_password.policy | LOW |
| validate_password.special_char_count | 1 |
+--------------------------------------+-------+
我希望这能帮助到人们。

MySQL 8*
SET GLOBAL validate_password.policy=LOW
参考链接解释政策-点击这里
步骤1:检查默认的身份验证插件
SHOW VARIABLES LIKE 'default_authentication_plugin';
步骤2:veryfing您的密码验证要求
SHOW VARIABLES LIKE 'validate_password%';
步骤3:使用正确的密码要求设置用户
CREATE USER '<your_user>'@'localhost' IDENTIFIED WITH '<your_default_auth_plugin>' BY 'password';
此错误消息与表中存储的密码无关。如果键入(在SQL控制台上)，也会出现这种情况
“选择密码(“123456789”)”
或者,如果
“select密码(’A123456789’)”
或者,如果
“select a ! 123456789’密码()”
如果你输入
“选择密码(A a123456789 !)”
那么它就会起作用。只需使用大+小字母，特殊字符和数字创建您的密码。
您可以在my.cnf中禁用这些检查，但这样您就会有安全风险!
在[mysqld]中添加:
validate_password_policy=LOW
validate_password_special_char_count=0
validate_password_length=0
validate_password_mixed_case_count=0
validate_password_number_count=0
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;
