saltstack学习-2 ：returnner-将结果发送给syslog和mysql（单边模式）

一，returnner介绍

1，默认情况下，发送给minion的命令执行结果将返回给salt-master。Saltstack Returnner的接口允许将结果发送给任意系统。

GitHub：https://github.com/saltstack/salt/tree/develop/salt/returners

官网：https://docs.saltstack.com/en/latest/ref/returners/

二，returnner模块列表

三，案例

1，returnner返回到syslog

salt-master执行命令：

[root@saltmaster ~]# salt '*' test.ping --return syslog
dns02:
    True
dns01:
    True

查看salt-minion端syslog日志

[root@dns02 ~]# tail -f /var/log/messages
Dec  9 22:22:31 dns02 python2.6: {"fun_args": [], "jid": "", "return": true, "retcode": 0, "success": true, "fun": "test.ping", "id": "dns02"}

2，returnner返回给mysql（单边模式）

• 安装mysql（可以在master也可以在其它服务器）

[root@saltmaster ~]# yum install –y mysql

• 启动mysql服务

[root@saltmaster tmp]# service mysql start
Starting MySQL........ SUCCESS!

• 设置root密码

[root@saltmaster tmp]# mysqladmin -u root password '123456'

• 创建数据库，并授权

--创建数据库
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; 

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`),KEY `jid` (`jid`),KEY `fun` (`fun`) ) 
ENGINE=InnoDB DEFAULT CHARSET=utf8;

--授权
GRANT ALL PRIVILEGES ON salt.* to 'salt'@'%' identified by 'salt';
flush privileges;

• 修改所有minion配置文件，在配置文件结尾添加：

[root@dns02 ~]# vi /etc/salt/minion
mysql.host: '10.80.0.162' 
mysql.user: 'salt' 
mysql.pass: 'salt' 
mysql.db: 'salt' 
mysql.port: 3306

• 重启所有minion服务

[root@saltmaster ~]# salt '*' service.restart salt-minion
dns01:
    True
dns02:
    True

• 所有minion安装MySQL-python模块

[root@saltmaster tmp]# salt '*' cmd.run 'yum install -y MySQL-python'
dns02:

• 测试写入mysql

[root@saltmaster tmp]# salt '*' cmd.run 'hostname' --return mysql
dns02:
    dns02
dns01:
    dns01

• 结果

mysql> select * from salt_returns;
