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

CREATE DATABASE  `salt`

DEFAULT CHARACTER SET utf8

DEFAULT COLLATE utf8_general_ci;

USE `salt`;

DROP TABLE IF EXISTS `jids`;

CREATE TABLE `jids` (

`jid` varchar(255) NOT NULL,

`load` mediumtext NOT NULL,

UNIQUE KEY `jid` (`jid`)

) ENGINE=InnoDB DEFAULT CHARSET=utf8;

DROP TABLE IF EXISTS `salt_returns`;

CREATE TABLE `salt_returns` (

`fun` varchar(50) NOT NULL,

`jid` varchar(255) NOT NULL,

`return` mediumtext NOT NULL,

`id` varchar(255) NOT NULL,

`success` varchar(10) NOT NULL,

`full_ret` mediumtext NOT NULL,

`alter_time` TIMESTAMP DEFAULT CURRENT_TIMESTAMP,

KEY `id` (`id`),

KEY `jid` (`jid`),

KEY `fun` (`fun`)

) ENGINE=InnoDB DEFAULT CHARSET=utf8;

DROP TABLE IF EXISTS `salt_events`;

CREATE TABLE `salt_events` (

`id` BIGINT NOT NULL AUTO_INCREMENT,

`tag` varchar(255) NOT NULL,

`data` varchar(1024) NOT NULL,

`alter_time` TIMESTAMP DEFAULT CURRENT_TIMESTAMP,

PRIMARY KEY (`id`),

KEY `tag` (`tag`)

) ENGINE=InnoDB DEFAULT CHARSET=utf8;

grant all on salt.* to salt@'172.31.%' identified by 'salt';

flush privileges ;

exit

[root@redis01-jp ~]#vim /etc/salt/master

#return: mysql

[root@redis01-jp ~]#/etc/init.d/salt-master restart

[root@redis01-jp ~]#salt '*' saltutil.refresh_pillar

[root@redis01-jp ~]#salt '*' test.ping

[root@redis01-jp ~]#mysql

use salt;

select * from salt_returns;

exit
