saltstack笔记

一.grains的两种使用方法：参考http://www.21yunwei.com/archives/3155

1. minion端：脚本：vim /etc/salt/minion.d/*.conf

   [root@99bill minion.d]# pwd
   /etc/salt/minion.d
   [root@99bill minion.d]# ls
   _schedule.conf  test.conf
   [root@99bill minion.d]# cat test.conf
   grains:
       name:
         -lanxiaohui
   

   　测试：

   [root@99bill minion.d]# salt 'minion102' grains.item name
   minion102:
       ----------
       name:
           -lanxiaohui
   

   　　

   　

2. master端：vim /srv/salt/_grains/cpu.py通过python脚本写入grains读取系统信息

   #!/usr/bin/python
   #coding:utf-8
   import os
   
   def cpu():
       grains = {}
       command = "top -b -n 1 | grep Cpu | awk -F'[:,]' '{print $5}'"
       with os.popen(command) as file:
           grains["cpu_id"] = file.read()
       return grains
   

   　　master端执行

   salt '*' saltutil.sync_all
   salt '*' sys.reload_modules
   查看效果
   salt '*' grains.item cup_id
   

   　　静态数据：vim /srv/salt/_grains/test.py

   #!/usr/bin/python
   #coding:utf-8
   
   def test():
       grains = {}
       grains['test_key'] = 'test sign'
       return grains
   

   　　

　　　　　　master端执行

salt '*' saltutil.sync_all
salt '*' sys.reload_modules
     查看效果
 salt '*' grains.item test_key

 二.pillar使用方法： vim /etc/salt/master

    

pillar_roots:
  base:
    - /srv/pillar

 vim /srv/pillar/top.sls

base:
    'minion102':
      - data
    'minion104':
      - data

 vim /srv/pillar/data.sls

name: lanxiaohui
age: 18
language:
    - php
    - js
    - python
cpu: {{ grains.cpu_id }}  #调用grains变量

 测试：

[root@99bill pillar]# salt '*' pillar.data language
minion105:
    ----------
minion106:
    ----------
minion102:
    ----------
    language:
        - php
        - js
        - python
minion103:
    ----------
minion104:
    ----------
    language:
        - php
        - js
        - python
[root@99bill pillar]# salt '*' pillar.data cpu
minion103:
    ----------
minion106:
    ----------
minion104:
    ----------
    cpu:
        93.9 id
minion105:
    ----------
minion102:
    ----------
    cpu:
        93.8 id
[root@99bill pillar]#
