runners

saltstack return 除了在配置文件中可以定义外(太繁琐),还可以自定义retunner，当然，这需要通过代码实现了,实现方式和自定义的pillar和grains类似,步骤如下:

#创建_returners目录,并创建脚本
[root@linux-node1 _returners]# pwd
/srv/salt/base/_returners
[root@linux-node1 _returners]# cat mysql_return.py    #这里脚本的名称需要和__virual__函数返回的一致
#!/usr/bin/env python
# _*_ coding:utf-8 _*_
__author__ = 'Charles Chang'

import json
import MySQLdb       #模块需要在master和minion端都安装

def __virtual__():
    return 'mysql_return'

def returner(ret):
    conn = MySQLdb.connect(host='192.168.74.20',user='salt',passwd='salt',db='salt',port=3306)
    cursor = conn.cursor()
    cursor.execute('INSERT INTO salt_returns VALUES (%s,%s,%s,%s,%s,%s)'%(json.dumps(ret['fun']),json.dumps(ret['jid']),
                   json.dumps(ret['return']),json.dumps(ret['id']),'"'+str(ret['success'])+'"',"'"+json.dumps(ret)+"'"))
    conn.commit()
    cursor.close()
    conn.close()

#创建mysql库和表
CREATE DATABASE `salt`
DEFAULT CHARACTER SET utf8
DEFAULT COLLATE utf8_general_ci;

GRANT ALL PRIVILEGES ON salt.* TO 'salt'@localhost IDENTIFIED BY 'salt';
GRANT ALL PRIVILEGES ON salt.* TO 'salt'@'%'  IDENTIFIED BY 'salt';

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,
KEY `id` (`id`),

) ENGINE=InnoDB DEFAULT CHARSET=utf8;
