随着MySQL 5.6 的GA, MySQL在一些细节上越来越美。 今天来体验下两个安全验证方面的细节提升。
1. mysql_config_edit 工具。 可以用来加密用户的密码,增强数据库安全。
使用方法:
-
t@ytt-centos6-3 ~]$ mysql_config_editor set --login-path=itsmine --host=localhost --user=ytt --password
-
Enter password:
-
[ytt@ytt-centos6-3 ~]$ mysql --login-path=itsmine -S /tmp/mysql3307.sock
-
Welcome to the MySQL monitor. Commands end with ; or \g.
-
...
-
mysql> select user();
-
+---------------+
-
| user() |
-
+---------------+
-
| ytt@localhost |
-
+---------------+
-
1 row in set (0.00 sec)
-
-
-
mysql> exit
-
Bye
mysql_config_edit 加密后的数据保存在用户主目录下:
-
[ytt@ytt-centos6-3 ~]$ file .mylogin.cnf
-
.mylogin.cnf: data
2. 密码强度验证插件
查看是否安装有此插件
-
mysql> show plugins;
-
+----------------------------+----------+--------------------+----------------------+-------------+
-
| Name | Status | Type | Library | License |
-
+----------------------------+----------+--------------------+----------------------+-------------+
-
| binlog | ACTIVE | STORAGE ENGINE | NULL | PROPRIETARY |
-
...
-
| validate_password | ACTIVE | VALIDATE PASSWORD | validate_password.so | PROPRIETARY |
-
+----------------------------+----------+--------------------+----------------------+-------------+
-
45 rows in set (0.00 sec)
-
-
-
mysql>
现在来设置新的密码:
-
mysql> set password for ytt_new@'localhost'= password('2lOp23dll&D');
-
Query OK, 0 rows affected (0.00 sec)
-
-
-
mysql> flush privileges;
-
Query OK, 0 rows affected (0.00 sec)
-
-
-
mysql>
