1. Returners列表

https://docs.saltstack.com/en/latest/ref/returners/all/index.html

2. 介绍mysql returner的用法

因mysql returner使用需要python MySQLdb模块，所以需要先安装MySQLdb模块。

2.1 安装pip和MySQLdb

在下列地址下载安装包。 
https://pypi.python.org/pypi/setuptools 
https://pypi.python.org/pypi/pip/

[root@salt-master111 tmp]# yum -y install python-devel mysql-devel
[root@salt-master111 tmp]# unzip setuptools-36.0.1.zip
[root@salt-master111 tmp]# cd setuptools-36.0.1
[root@salt-master111 tmp]# python setup.py install
[root@salt-master111 tmp]# cd ../
[root@salt-master111 tmp]# tar -zxvf pip-9.0.1.tar.gz 
[root@salt-master111 tmp]# cd pip-9.0.1
[root@salt-master111 tmp]# python setup.py install
[root@salt-master111 tmp]# pip install mysql
[root@salt-master111 tmp]# python
Python 2.7.5 (default, Nov  6 2016, 00:28:07) 
[GCC 4.8.5 20150623 (Red Hat 4.8.5-11)] on linux2

2.2 配置mysql数据库

使用官方的数据表结构，并给minion服务器相关权限。

CREATE DATABASE  `salt`
  DEFAULT CHARACTER SET utf8
  DEFAULT COLLATE utf8_general_ci;

USE `salt`;

--
-- Table structure for table `jids`
--

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;
CREATE INDEX jid ON jids(jid) USING BTREE;

--
-- Table structure for table `salt_returns`
--

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;

--
-- Table structure for table `salt_events`
--

DROP TABLE IF EXISTS `salt_events`;
CREATE TABLE `salt_events` (
`id` BIGINT NOT NULL AUTO_INCREMENT,
`tag` varchar(255) NOT NULL,
`data` mediumtext NOT NULL,
`alter_time` TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
`master_id` varchar(255) NOT NULL,
PRIMARY KEY (`id`),
KEY `tag` (`tag`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

grant all on salt.* to salt@"10.1.0.%" identified by "saltpass";

2.2 配置salt-master

/etc/salt/master

return: mysql
mysql.host: 'salt-host'
mysql.user: 'salt'
mysql.pass: 'saltpass'
mysql.db: 'salt'

重启master和minion服务

systemctl restart salt-master
systemctl restart salt-minion

2.3 测试

master端执行命令。

[root@salt-master111 ~]# salt 'salt-master111' test.ping --return mysql
salt-master111:
    True
[root@salt-master111 ~]# 

在数据库中查看，salt_returns是否有数据进来。

mysql> select * from salt_returns;
