引言
之前 Salt 远程执行的学习谈到了 Returners，现在我们来实际配置下 Returners。
以下 Returners 例子是将 minion 的结果数据发送到 master 的 MySQL 数据库上。
1 Minion 上安装 MySQL-python
To enable this returner, the minion will need the python client for mysql installed.
返回数据是 minion 直接返回的，所有的 minion 要装 Python 的 MySQL 客户端
使用 Salt 批量安装 MySQL-python
salt ‘*’ state.single pkg.installed name=MySQL-python
2 创建并初始化存放 Returners 数据的数据库
# 使用以下 sql 在 Master 上创建 salt 数据库及相关表
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;
# 创建及配置用户权限
grant all on salt.* to salt@'%' identified by 'salt@pw';
flush privileges;
mysql -h 192.168.56.11 -usalt -psalt@pw
3 修改 Minion 配置文件
# 增加如下内容，支持 Returners MySQL:
mysql.host: '192.168.56.11'
mysql.user: 'salt'
mysql.pass: 'salt@pw'
mysql.db: 'salt'
mysql.port: 3306
# 修改配置文件需要重启 Minion
systemctl restart salt-minion
4 检查 Returners MySQL 结果
[root@linux-node1 ~]# salt '*' test.ping --return mysql
linux-node1.example.com:
True
linux-node2.example.com:
True
MariaDB [salt]> select * from salt.salt_returns\G
*************************** 1. row ***************************
fun: test.ping
jid: 20160629174902075344
return: true
id: linux-node1.example.com
success: 1
full_ret: {"fun_args": [], "jid": "20160629174902075344", "return": true, "retcode": 0, "success": true, "fun": "test.ping", "id": "linux-node1.example.com"}
alter_time: 2016-06-29 17:49:02
*************************** 2. row ***************************
