SaltStack之return与job管理

SaltStack组件之return

return组件可以理解为SaltStack系统对执行Minion返回后的数据进行存储或者返回给其他程序，它支持多种存储方式，比如用MySQL、MongoDB、Redis、Memcache等，通过return我们可以对SaltStack的每次操作进行记录，对以后日志审计提供了数据来源。目前官方已经支持30种return数据存储与接口，我们可以很方便的配置与使用它。当然也支持自己定义的return，自定义的return需由python来编写。在选择和配置好要使用的return后，只需在salt命令后面指定return即可。

# 查看node1上所有return列表
[root@master ~]# salt node1 sys.list_returners
node1:
    - carbon
    - couchdb
    - etcd
    - highstate
    - local
    - local_cache
    - mattermost
    - multi_returner
    - pushover
    - rawfile_json
    - slack
    - slack_webhook
    - smtp
    - splunk
    - sqlite3
    - syslog
    - telegram

return流程

return是在Master端触发任务，然后Minion接受处理任务后直接与return存储服务器建立连接，然后把数据return存到存储服务器。关于这点一定要注意，因为此过程都是Minion端操作存储服务器，所以要确保Minion端的配置跟依赖包是正确的，这意味着我们将必须在每个Minion上安装指定的return方式依赖包，假如使用Mysql作为return存储方式，那么我们将在每台Minion上安装python-mysql模块。

使用mysql作为return存储方式

环境说明：

job cache

job cache流程

return时是由Minion直接与存储服务器进行交互，因此需要在每台Minion上安装指定的存储方式的模块，比如python-mysql，那么我们能否直接在Master上就把返回的结果给存储到存储服务器呢？

答案是肯定的，这种方式被称作 job cache 。意思是当Minion将结果返回给Master后，由Master将结果给缓存在本地，然后将缓存的结果给存储到指定的存储服务器，比如存储到mysql中。

示意图

master默认的存储位置

[root@master ~]# cd /var/cache/salt/master/jobs/
[root@master jobs]# ls

job 管理

Salt 0.9.7 为管理作业的saltutil引入了一些新功能。这些功能是：

running返回在proc目录中找到的所有运行作业的数据。
find_job根据工作 ID 返回有关某项工作的具体数据。
signal_job允许向给定夹具发送信号。
term_job向控制指定作业的流程发送终止信号（SIGTERM，15）。
kill_job向控制指定作业的流程发送杀伤信号（SIGKILL，9）。
