mysql 5.7密码策略

刚装上5.7  改个密码也得要复杂度

看看

root@localhost [(none)]> show global variables like '%validate_password%';
+--------------------------------------+--------+
| Variable_name                        | Value  |
+--------------------------------------+--------+
| validate_password_check_user_name    | OFF    |
| 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 (0.00 sec)

卸了这个插件

root@localhost [(none)]> uninstall plugin validate_password ;

在看看
root@localhost [(none)]>  show global variables like '%validate_password%';
Empty set (0.00 sec)

上线的时候在装上

INSTALL PLUGIN validate_password SONAME 'validate_password.so';
