环境
mysql> select version(); +-----------+ | version() | +-----------+ | 8.0.16 | +-----------+
报错
创建用户的时候报错
create user 'user1'@'%' identified by '123456'; ERROR 1819 (HY000): Your password does not satisfy the current policy requirements
原因
密码设置的过于简单
解决：
修改密码的验证策略
-- 查看密码的验证策略 mysql> SHOW VARIABLES LIKE 'validate_password%'; +--------------------------------------+--------+ | Variable_name | Value | +--------------------------------------+--------+ | validate_password.check_user_name | ON | | 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 (0.03 sec) -- 修改密码的验证策略 MEDIUM(中等)修改为LOW(低) mysql> set global validate_password.policy = 0; -- 修改密码的长度 mysql> set global validate_password.length = 4; -- 再次查看，确认设置已经修改 mysql> SHOW VARIABLES LIKE 'validate_password%'; +--------------------------------------+-------+ | Variable_name | Value | +--------------------------------------+-------+ | validate_password.check_user_name | ON | | validate_password.dictionary_file | | | validate_password.length | 4 | | validate_password.mixed_case_count | 1 | | validate_password.number_count | 1 | | validate_password.policy | LOW | | validate_password.special_char_count | 1 | +--------------------------------------+-------+
成功
-- 可以创建成功了 mysql> create user 'user1'@'%' identified by '123456'; Query OK, 0 rows affected (0.01 sec)
