一、grains
grains 是在 minion（客戶端）啓動時收集到的一些信息，好比操做系統類型、網卡ip等。強調是minion啓動時收集到的數據，因此若是改了什麼硬件啥的，要重啓minion才能收集，要否則仍是老數據。node

1.1）列出grains的keypython

[root@master salt]# salt '192.168.222.145' grains.ls

1.2）顯示全部的key及對應key的值nginx

[root@master salt]# salt '192.168.222.145' grains.items

1.3）顯示單個key對應的值web

[root@master salt]# salt '192.168.222.145' grains.item fqdn
192.168.222.145:
    ----------
    fqdn:
        master

[root@master salt]# salt '192.168.222.145' grains.get fqdn
192.168.222.145:
    master

1.4）根據grains匹配並操做，以下匹配全部操做系統是centos的機器並執行wapache

[root@master salt]# salt -G os:CentOS cmd.run 'w'
192.168.222.146:
     01:42:30 up  5:59,  1 user,  load average: 0.00, 0.00, 0.00
    USER     TTY      FROM              LOGIN@   IDLE   JCPU   PCPU WHAT
    root     pts/1    192.168.222.1    19:43   56:20   0.34s  0.34s -bash
192.168.222.145:
     01:42:32 up  6:01,  1 user,  load average: 0.10, 0.05, 0.01
    USER     TTY      FROM              LOGIN@   IDLE   JCPU   PCPU WHAT
    root     pts/1    192.168.222.1    19:41    1.00s  1.07s  0.45s /usr/bin/python

1.5）也能夠自定義grains，而後來匹配，在minion的配置文件中修改vim

[root@master ~]# vim /etc/salt/minion
grains:
  roles:
    - webserver
    - memcache

匹配角色是memcache的機器並輸出hehecentos

[root@master ~]# salt -G roles:memcache cmd.run 'echo hehe'
192.168.222.145:
    hehe

1.6）也能夠本身建立一個文件來匹配grainsbash

[root@master ~]# vim /etc/salt/grains
web: nginx
這個web不要跟minion裏面的重複

[root@master ~]# salt -G web:nginx cmd.run 'uptime'
192.168.222.145:
     01:52:23 up  6:10,  1 user,  load average: 0.08, 0.05, 0.00

1.7）top.sls裏面也能夠經過grains匹配spa

[root@master ~]# vim /srv/salt/top.sls 
base:
  'web:nginx':
    - match: grain
    - apache

[root@master ~]# salt '*' state.highstate
192.168.222.146:
----------
          ID: states
    Function: no.None
      Result: False
     Comment: No Top file or external nodes data matches found.
     Started: 
    Duration: 
     Changes:

Total states run:     1
192.168.222.145:
----------
          ID: apache-install
    Function: pkg.installed
        Name: httpd
      Result: True
     Comment: Package httpd is already installed.
     Started: 03:02:16.972245

     Changes:

    Function: pkg.installed

      Result: True
     Comment: Package httpd-devel is already installed.
     Started: 03:02:18.291724
    Duration: 0.646 ms
     Changes:

          ID: apache-service
    Function: service.running
        Name: httpd
      Result: True
     Comment: Service httpd is already enabled, and is in the desired state
     Started: 03:02:18.293048
    Duration: 50.703 ms
     Changes:   

Summary
------------
Succeeded: 3
Failed:    0

Total states run:     3
ERROR: Minions returned with non-zero exit code

二、Pillar，給minion指定的數據，給誰指定誰就能看到。以下開啓pillar，修改配置以後重啓服務，可能或會纔會有響應。　　操作系統

[root@master ~]#  vim /etc/salt/master
pillar_opts: True

[root@master salt]# salt '*' pillar.items

2.1）定義pillar數據，這個入口文件的要求是跟grains同樣的

[root@master ~]# vim /etc/salt/master 
pillar_roots:
  base:
    - /srv/pillar

pillar_opts: False

改成false

[root@master ~]# mkdir /srv/pillar

[root@master pillar]# pwd
/srv/pillar
[root@master pillar]# cat apache.sls 
{% if grains['os'] == 'CentOS' %}
apache: httpd
{% elif grains['os'] == 'Debian' %}
apache: apache2
{% endif %}
[root@master pillar]# cat top.sls 
base:
  '*':
    - apache

刷新一下
[root@master pillar]# salt '*' saltutil.refresh_pillar
192.168.222.145:
    True
192.168.222.146:
    True
[root@master pillar]# salt -I 'apache:httpd' test.ping
192.168.222.145:
    True
192.168.222.146:
    True

Grains

minion

靜態數據

minion啓動時收集，也可使用

saltutil.sync_grains進行刷新。

存儲minion基本數據。好比用於匹配minion，

自身數據能夠用來作資產管理等。
