Saltstack把数据返回到mysql服务器以及编写执行模块

Storing Job Results in an External System

图解

当配置外部作业缓存时，数据像往常一样返回salt master上的缺省作业缓存，然后使用在salt minion上运行的 Salt returne模块将结果发送到外部作业缓存。

在这种配置中，salt minions 像往常一样将数据发送到默认作业缓存，然后salt master使用运行在盐主机上的盐返回器模块将数据发送到外部系统。

第一种配置

[root@server1 files]# yum  install  mysql-server -y
[root@server2 ~]# yum  install -y MySQL-python.x86_64

[root@server2 ~]# vim  /etc/salt/minion
814 mysql.host: '172.25.7.1'
815 mysql.user: 'salt'
816 mysql.pass: 'westos'
817 mysql.db: 'salt'
818 mysql.port: 3306
[root@server2 ~]# /etc/init.d/salt-minion restart

[root@server1 files]# mysql
mysql> grant all  on salt.*  to  salt@'172.25.7.%' identified by 'westos';

[root@server1 ~]# vim  test.sql
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;
[root@server1 ~]# mysql <  test.sql

测试:

[root@server1 ~]# salt 'server2' test.ping --return  mysql
server2:
    True

[root@server1 ~]# mysql 
mysql> use  salt;
mysql> show  tables;
+----------------+
| Tables_in_salt |
+----------------+
| jids           |
| salt_events    |
| salt_returns   |
+----------------+
3 rows in set (0.00 sec)

mysql> select * from  salt_returns
    -> ;

第二种配置

[root@server1 ~]# yum  install  -y MySQL-python.x86_64

[root@server1 ~]# mysql
mysql> grant all  on salt.*  to  salt@localhost identified by 'westos';Query OK, 0 rows affected (0.00 sec)

mysql> flush  privileges;
Query OK, 0 rows affected (0.00 sec)

[root@server1 ~]# vim  /etc/salt/master
1059 master_job_cache: mysql
1060 mysql.host: 'localhost'
1061 mysql.user: 'salt'
1062 mysql.pass: 'westos'
1063 mysql.db: 'salt'
1064 mysql.port: 3306
[root@server1 ~]# /etc/init.d/salt-master restart

测试：

[root@server1 ~]# salt  server3 cmd.run 'df -h'
server3:
    Filesystem                    Size  Used Avail Use% Mounted on
    /dev/mapper/VolGroup-lv_root   19G  1.1G   17G   6% /

    /dev/vda1                     485M   33M  427M   8% /boot

编写模块

[root@server1 ~]# mkdir  /srv/salt/_modules
[root@server1 ~]# cd  /srv/salt/_modules/
[root@server1 _modules]# vim  my_disk.py
#!/usr/bin/env python

def df():
    return __salt__['cmd.run']('df -h')

[root@server1 _modules]# salt '*' saltutil.sync_modules
server3:
    - modules.my_disk
server2:
    - modules.my_disk
server1:
    - modules.my_disk
server4:
    - modules.my_disk
