04_Returners组件：返回jobid的结果到mysql

1、前期调研

0、环境

salt 2019

python3.6  很重要

2、jobid问题

1、异步执行，maseter返回jobid，前端何时，去查看该jobid的结果。此时如果有个回调函数就更好了。

2、研究salt发现 --return 模块，可以自动把异步执行的结果写入数据库，这样就不需要查询了，直接从数据库里面取值即可。

1、centos7.3，salt2019，python3.6下的安装

1、安装MySQL

安装参考  https://www.cnblogs.com/venicid/p/11956731.html

成功

2、安装MySQLdb模块

 安装参考 https://www.cnblogs.com/venicid/p/11950519.html

对于，该环境来说。此处必须指定位置安装，MySQLdb与salt包位置，一样，

详情请见  https://www.cnblogs.com/venicid/p/11958498.html

[root@IP salt]# pip3 install --target=/usr/lib/python3.6/site-packages/ mysql-client

成功

2、建立数据库表

官网：https://docs.saltstack.com/en/latest/ref/returners/all/salt.returners.mysql.html

建立三个表

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;

 授权

mysql> grant all on salt.* to salt@"%" identified by "XXXXX";
Query OK, 0 rows affected, 1 warning (0.00 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.11 sec)

成功

3、master配置

[root@IP ~]# vim /etc/salt/master

mysql.host: '192.168.23.21'
mysql.user: 'salt'
mysql.pass: 'XXXXX'
mysql.db: 'salt'
mysql.port: 3306
return: mysql
master_job_cache: mysql

重启master

[root@IP ~]# systemctl restart salt-master

4、执行salt命令，查看

先查看下

同步执行下

[root@IP ~]# salt "192.168.23.21" test.ping
192.168.23.21:
    True

 

 异步执行下，5个都存在

[root@IP ~]# salt --async  \*  cmd.run "hostname -I"
Executed command with job ID: 20191129210622671777

5、安装ERROR解决
