本文详细介绍了SaltStack的两大核心数据系统Grains和Pillar。Grains用于收集和存储minion的静态信息，如CPU、内存等；Pillar则作为数据管理中心，存储配置管理所需的动态数据，如软件版本、用户名密码等。

SaltStack之数据系统

SaltStack数据系统

SaltStack有两大数据系统，分别是：

Grains
Pillar

SaltStack数据系统组件

SaltStack组件之Grains

Grains是SaltStack的一个组件，其存放着minion启动时收集到的信息。

Grains是SaltStack组件中非常重要的组件之一，因为我们在做配置部署的过程中会经常使用它，Grains是SaltStack记录minion的一些静态信息的组件。可简单理解为Grains记录着每台minion的一些常用属性，比如CPU、内存、磁盘、网络信息等。我们可以通过grains.items查看某台minion的所有Grains信息。

Grains的功能：

收集资产信息

Grains应用场景：

信息查询
在命令行下进行目标匹配
在top file中进行目标匹配
在模板中进行目标匹配

模板中进行目标匹配请看：https://docs.saltstack.com/en/latest/topics/pillar/

信息查询实例：

[root@master ~]#

查询某个key的键值，使用grains.get

//获取主机IP地址
[root@master ~]# salt 'node1' grains.get fqdn_ip4
node1:
    - 192.168.10.202
[root@master ~]# salt 'node2' grains.get ip4_interfaces
node2:
    ----------
    ens33:
        - 192.168.10.203
    lo:
        - 127.0.0.1
[root@master ~]# salt '*' grains.get ip4_interfaces:ens33
node2:
    - 192.168.10.203
master:
    - 192.168.10.201
node1:
    - 192.168.10.202
[root@master ~]#

目标匹配实例：
用Grains来匹配minion：

//匹配所有系统为Centos Stream的主机
[root@master ~]# salt -G 'os:CentOS Stream' cmd.run 'uptime'
node2:
     06:55:27 up 29 min,  1 user,  load average: 0.00, 0.00, 0.00
master:
     06:55:27 up 29 min,  1 user,  load average: 0.02, 0.01, 0.01
node1:
     06:55:27 up 29 min,  1 user,  load average: 0.00, 0.00, 0.00
[root@master ~]#

在top file里面使用Grains：

[root@master ~]# vim /srv/salt/base/top.sls 
base:
  'os:Centos Stream'
    - web.mysql.install

  'node1':
    - web.apache.install

  'node2':
    - web.nginx.install

自定义Grains的两种方法：

minion配置文件，在配置文件中搜索grains
在/etc/salt下生成一个grains文件，在此文件中定义(推荐方式)

//控制端
[root@master ~]# vim /etc/salt/grains 
#grains:
#  roles:
#    - webserver
#    - memcache
#  deployment: datacenter4
#  cabinet: 13
#  cab_u: 14-15
grains:							
  test-grains: im master		//添加此处两行
[root@master ~]# systemctl restart salt-minion.service

//被控端node1
[root@node1 ~]# vim /etc/salt/minion
#grains:
#  roles:
#    - webserver
#    - memcache
#  deployment: datacenter4
#  cabinet: 13
#  cab_u: 14-15
grains:
  test-grains: im node1		//添加此处
[root@node1 ~]# systemctl restart salt-minion.service 

//在master上查看
[root@master ~]# salt -L master,node1 grains.get test-grains
master:
    im master
node1:
    im node1
[root@master ~]#

不重启的情况下自定义Grains：

[root@master ~]# vim /etc/salt/grains 
test-grains: im master
goodboy: is me

[root@master ~]# salt 'master' saltutil.sync_grains 
master:
[root@master ~]# salt 'master' grains.get goodboy
master:
    is me
[root@master ~]#

SaltStack组件之Pillar

Pillar也是SaltStack组件中非常重要的组件之一，是数据管理中心，经常配置states在大规模的配置管理工作中使用它。Pillar在SaltStack中主要的作用就是存储和定义配置管理中需要的一些数据，比如软件版本号、用户名密码等信息，它的定义存储格式与Grains类似，都是YAML格式。

在Master配置文件中有一段Pillar settings选项专门定义Pillar相关的一些参数：

#pillar_roots:
#  base:
#    - /srv/pillar

默认Base环境下Pillar的工作目录在/srv/pillar目录下。若你想定义多个环境不同的Pillar工作目录，只需要修改此处配置文件即可。

Pillar的特点：

可以给指定的minion定义它需要的数据
只有指定的人才能看到定义的数据
在master配置文件里设置

[root@master ~]# salt '*' pillar.items
node2:
    ----------
master:
    ----------
node1:
    ----------
[root@master ~]#

默认pillar是没有任何信息的，如果想查看信息，需要在 master 配置文件上把 pillar_opts的注释取消，并将其值设为 True。

[root@master ~]# vim /etc/salt/master
····省略部分·····
# master config file that can then be used on minions.
pillar_opts: True

# The pillar_safe_render_error option prevents the master from passing pillar
····省略部分·····


##重启master并查看pillar的信息

Grains与Pillar的区别

	存储位置	类型	采集方式	应用场景
Grains	minion	静态	minion启动时采集可通过刷新避免重启minion服务	1.信息查询 2.在命令行下进行目标匹配 3.在top file中进行目标匹配 4.在模板中进行目标匹配
Pillar	master	动态	指定，实时生效	1.目标匹配 2.敏感数据配置
