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

（2.打印node2节点的eth0网卡的ip信息和mac信息
[[email protected] ~]# salt ‘node2‘ grains.get ip4_interfaces:eth0 node2: - 192.168.64.129 [[email protected] ~]# 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 [[email protected] ~]# salt ‘node2‘ grains.get os node2: CentOS #获取系统版本 [[email protected] ~]# salt ‘node2‘ grains.get osrelease node2: 6.5 #获取内核版本 [[email protected] ~]# 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
[[email protected] pillar]# pwd
/srv/pillar
[[email protected] pillar]# tree -n .
.
├── info.sls
└── top.sls
0 directories, 2 files
#创建一个用于测试info文件
[[email protected] 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
[[email protected] 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]
[[email protected] 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]
[[email protected] 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......
