mysql> ALTER USER ‘root‘@‘localhost‘ IDENTIFIED BY ‘111‘;
ERROR 1819 (HY000): Your password does not satisfy the current policy requirements
原因是因为MySQL有密码设置的规范，具体是与validate_password_policy的值有关：
MySQL完整的初始密码规则可以通过如下命令查看：
mysql> SHOW VARIABLES LIKE ‘validate_password%‘; +--------------------------------------+-------+ | Variable_name | Value | +--------------------------------------+-------+ | validate_password_check_user_name | OFF | | 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 | +--------------------------------------+-------+ 7 rows in set (0.01 sec)
解决方法：
mysql> set global validate_password_policy=0; mysql> set global validate_password_length=1;
这样就可以设置简单的密码了。
