saltstack自动化运维系列④之saltstack的命令返回结果mysql数据库写入
salt的返回值写入mysql数据库：
可参考：
https://docs.saltstack.com/en/latest/ref/returners/all/salt.returners.mysql.html#module-salt.returners.mysql
在mysql数据库中创建数据库、表
CREATE DATABASE `salt`
DEFAULT CHARACTER SET utf8
DEFAULT COLLATE utf8_general_ci; USE `salt`; 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; 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; 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; mysql> show tables;
+----------------+
| Tables_in_salt |
+----------------+
| jids |
| salt_events |
| salt_returns | mysql> grant all on salt.* to salt@'%' identified by 'salt';
安装python插件
# yum install MySQL-python -y
将以下配置分别配置到服务端和客户端：
/etc/salt/master
/etc/salt/minion
mysql.host: '192.168.3.19'
mysql.user: 'salt'
mysql.pass: 'salt'
mysql.db: 'salt'
mysql.port: 3306
执行命令后面跟 --return mysql 可以将执行的结果和命令记录到mysql数据库中
# salt '*' test.ping --return mysql
node2.chinasoft.com:
True
mini1:
True
[root@mini1 ~]# salt '*' cmd.run 'date' --return mysql
node2.chinasoft.com:

可以看到表 salt_returns 中的数据

至此saltstack命令行结果返回mysql数据库配置完毕，很多时候可以通过查询数据库得知哪些客户端没有返回我们想要的结果，可以方便的查询并进行二次处理
