标签:saltstack grains pillar

Grains和Pillar的用途:

    Grains : 用于存储minion的基本数据信息;

    Pillar : 用于存储master分配给minion的数据信息。

Grains和Pillar的存储区域:

    Grains : 元数据存储在minion端;

    Pillar : 元数据存储在master端。

Grains和Pillar的更新方式:

    Grains : 在minion启动时进行更新;

    Pillar : 元数据存储在master端,使用 saltutil.refresh_pillar进行刷新,效率更高,更为灵活。

 

1.Grains的简单使用

 (1.打印所有items值

[root@node1 ~]# salt ‘node2‘ grains.items

(2.打印node2节点的eth0网卡的ip信息和mac信息

[root@node1 ~]# salt ‘node2‘ grains.get ip4_interfaces:eth0   
node2:
    - 192.168.64.129
[root@node1 ~]# salt ‘node2‘ grains.get hwaddr_interfaces:eth0
node2:
    00:50:56:25:fc:e1

(3.打印node2节点系统信息

#获取系统信息
[root@node1 ~]# salt ‘node2‘ grains.get os
node2:
    CentOS
#获取系统版本
[root@node1 ~]# salt ‘node2‘ grains.get osrelease  
node2:
    6.5
#获取内核版本    
[root@node1 ~]# salt ‘node2‘ grains.get kernelrelease
node2:
    2.6.32-431.el6.x86_64

2.Pallir的简单使用

#需要创建目录
[root@node1 pillar]# pwd
/srv/pillar
[root@node1 pillar]# tree -n .
.
├── info.sls
└── top.sls
0 directories, 2 files
#创建一个用于测试info文件 
[root@node1 pillar]# cat info.sls 
#判断系统是否为CentOS
{% if grains.os == ‘CentOS‘ %}
#如果为CentOS,则打印nginx版本 [内容自定义]
nginx: nginx-1.4.7 
{% endif %}
#此文件必须为top.sls
[root@node1 pillar]# cat top.sls 
base:
  ‘node2‘:
    #对应info.sls文件名称
    - info
#刷新缓存 [显示True说明刷新成功]      
[root@node1 pillar]# salt ‘node2‘ saltutil.refresh_pillar
node2:
    True 
#测试结果 [如果显示内容为info文件的信息,说明成功]
[root@node1 pillar]# salt ‘node2‘ pillar.get nginx
node2:
    nginx-1.4.7

这里需要说明一下的是,pillar使用的是YAML语言,而Saltstack使用的是Python来解析YAML,所有说如果你会Python语言的话,pillar很容易理解和学习的......
