似乎我无意中在MySQL 5.7中加载了密码验证插件。这个插件似乎强制所有密码遵守某些规则。
我想把这个关了。
我已经尝试按照这里的建议更改validate_password_length变量，但没有用。
mysql> SET GLOBAL validate_password_length=4;
Query OK, 0 rows affected (0.00 sec)
mysql> SET PASSWORD FOR 'app' = PASSWORD('abcd');
ERROR 1819 (HY000): Your password does not satisfy the current policy requirements
我想要么卸载插件或中性它以某种方式。
当前回答
卸载:
mysql> uninstall plugin validate_password;
show plugins不会显示卸载的插件;
安装:
mysql> install plugin validate_password SONAME 'validate_password.so';
配置禁用:
[mysqld]
validate_password = OFF
只有安装了插件，才能通过配置禁用该插件。

使用命令登录到您的MariaDB服务器
mysql -u root
or
mysql -u root -pYOURPASSWORD
UPDATE mysql.user SET plugin = 'mysql_native_password' WHERE user = 'root' AND plugin = 'unix_socket';
and
FLUSH PRIVILEGES;
回复你的问题:我如何关闭mysql密码验证?
简单的回答:您可以降低复杂性。
以root用户登录Mysql客户端。
set global validate_password.policy = LOW;
set global validate_password.length = 2;
set global validate_password.mixed_case_count = 0;
set global validate_password.number_count = 0;
set global validate_password.special_char_count = 0;
继续创建用户…
卸载:
mysql> uninstall plugin validate_password;
show plugins不会显示卸载的插件;
安装:
mysql> install plugin validate_password SONAME 'validate_password.so';
配置禁用:
[mysqld]
validate_password = OFF
只有安装了插件，才能通过配置禁用该插件。
根据Sharfi的回答，编辑/etc/my.cnf文件并添加这一行:
validate_password_policy=LOW
这应该足以中和op所要求的验证。在这个更改之后，您可能需要重新启动mysqld。根据你的操作系统，它看起来像这样:
sudo service mysqld restart
validate_password_policy takes either values 0, 1, or 2 or words LOW, MEDIUM, and STRONG which correspond to those numbers. The default is MEDIUM (1) which requires passwords contain at least one upper case letter, one lower case letter, one digit, and one special character, and that the total password length is at least 8 characters. Changing to LOW as I suggest here then only will check for length, which if it hasn't been changed through other parameters will check for a length of 8. If you wanted to shorten that length limit too, you could also add validate_password_length in to the my.cnf file.
有关级别和细节的更多信息，请参阅mysql文档。
对于MySQL 8，属性已经从“validate_password_policy”更改为“validate_password.policy”。请参阅更新后的mysql文档获取最新信息。
对于参考文献和未来，你应该阅读这里的文档https://dev.mysql.com/doc/mysql-secure-deployment-guide/5.7/en/secure-deployment-password-validation.html
然后你应该编辑你的mysqld.cnf文件，例如:
vim /etc/mysql/mysql.conf.d/mysqld.cnf
然后，添加[mysqld]部分，如下所示:
plugin-load-add=validate_password.so
validate_password_policy=LOW
基本上，如果你编辑你的默认，它将看起来像:
[mysqld]
#
# * Basic Settings
#
user = mysql
pid-file = /var/run/mysqld/mysqld.pid
socket = /var/run/mysqld/mysqld.sock
port = 3306
basedir = /usr
datadir = /var/lib/mysql
tmpdir = /tmp
lc-messages-dir = /usr/share/mysql
skip-external-locking
plugin-load-add=validate_password.so
validate_password_policy=LOW
然后，您可以重新启动:
systemctl restart mysql
如果您忘记了plugin-load-add=validate_password。所以部分，你会在重新启动时出现错误。
享受吧!
