Salt返回接收器（returner）允许把minion的响应保存在各种数据存储或不同的位置，甚至把响应内容显示在命令行。Returner可以用来扩展Salt，和新的、定制的接口和支持新的数据库进行通信。本例用mysql存储salt返回值
操作如下：
[root@redis01-jp ~]# yum -y install mysql-connector-python
[root@redis01-jp ~]# yum -y install MySQL-python27
[root@redis01-jp ~]# yum -y install mysql-server
[root@redis01-jp ~]# /etc/init.d/mysqld start
[root@redis01-jp ~]# mysql
