saltstack的配置管理与数据系统
作者：互联网
YAML语言
YAML是一种直观的能够被电脑识别的数据序列化格式，是一个可读性高并且容易被人类阅读，容易和脚本语言交互，用来表达资料序列的编程语言。
它类似于标准通用标记语言的子集XML的数据描述语言，语法比XML简单很多。
YAML语言的格式如下：
house:
family:
name: Doe
parents:
- John
- Jane
children:
- Paul
- Mark
- Simone
address:
number: 34
street: Main Street
city: Nowheretown
zipcode: 12345
YAML的基本规则：
使用缩进来表示层级关系，每层2个空格，禁止使用TAB键
当冒号不是处于最后时，冒号后面必须有一个空格
用 - 表示列表，- 的后面必须有一个空格
用 # 表示注释
YAML配置文件要放到SaltStack让我们放的位置，可以在SaltStack的 Master 配置文件中查找file_roots即可看到。
[root@master salt]# pwd
/etc/salt
[root@master salt]# vim master
681 file_roots:
682 base:
683 - /srv/salt/base
684 test:
685 - /srv/salt/test
686 dev:
687 - /srv/salt/dev
688 prod:
689 - /srv/salt/prod
[root@master ~]# mkdir -p /srv/salt/{base,test,dev,prod}
[root@master base]# systemctl restart salt-master.service
[root@master base]# systemctl restart salt-minion.service
需要注意：
base是默认的位置，如果file_roots只有一个，则base是必备的且必须叫base，不能改名
使用SaltStack配置一个apache实例
在Master上部署sls配置文件并执行
[root@master base]# pwd
/srv/salt/base
[root@master base]# mkdir -p web/apache
[root@master apache]# pwd
/srv/salt/base/web/apache
[root@master apache]# touch apache.sls //生成一个状态描述文件
[root@master apache]# vim apache.sls
apache-install:
pkg.installed:
- name: httpd
apache-service:
service.running:
- name: httpd
- enable: True
// YAML 配置文件中顶格写的被称作ID，必须全局唯一，不能重复
// SaltStack 读 YAML 配置文件时是从上往下读，所以要把先执行的写在前面
在执行状态文件前先用test.ping测试需要执行状态文件的主机是否能正常通信，然后再执行状态文件。
[root@master salt]# salt 'minion01' test.ping
minion01:
True
//执行状态描述文件
[root@master ~]# salt 'minion01' state.sls web.apache.apache saltenv=base

top file介绍
直接通过命令执行sls文件时够自动化吗？答案是否定的，因为我们还要告诉某台主机要执行某个任务，自动化应该是我们让它干活时，它自己就知道哪台主机要干什么活，但是直接通过命令执行sls文件并不能达到这个目的，为了解决这个问题，top file 应运而生。
top file就是一个入口，top file的文件名可通过在 Master的配置文件中搜索top.sls找出，且此文件必须在 base 环境中，默认情况下此文件必须叫top.sls。
top file的作用就是告诉对应的主机要干什么活，比如让web服务器启动web服务，让数据库服务器安装mysql等等。
案例
[root@master base]# pwd
/srv/salt/base
[root@master base]# touch top.sls
[root@master base]# vim top.sls
base: //要执行状态文件的环境
'minion01': //要执行状态文件的目标
- web.apache.apache //要执行的状态文件
//停掉minion01上的httpd服务，进行测试
[root@minion01 salt]# systemctl stop httpd.service
[root@master base]# salt 'minion01' state.highstate //使用高级状态来执行

注意： 若top file里面的目标是用表示的，要注意的是，top file里面的表示的是所有要执行状态的目标，而salt ‘’ state.highstate里面的表示通知所有机器干活，而是否要干活则是由top file来指定的
高级状态highstate的使用
管理SaltStack时一般最常用的管理操作就是执行高级状态。
[root@master salt]# salt '*' state.highstate //在生产环境中不要使用此操作
注意： 上面让所有人执行高级状态，但实际工作中，一般不会这么用，工作当中一般都是通知某台或某些台目标主机来执行高级状态，具体是否执行则是由top file来决定的。
若在执行高级状态时加上参数test=True，则它会告诉我们它将会做什么，但是它不会真的去执行这个操作。
停掉minion上的httpd服务
[root@minion01 ~]# systemctl stop httpd
在master上执行高级状态的测试
[root@master salt]# salt 'minion01' state.highstate test=true

SaltStack数据系统
SaltStack有两大数据系统，分别是：
Grains
Pillar
Grains与Pillar的区别
| 数据系统 | 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 | 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 |
| Pillar | master | 动态 | 指定，实时生效 | 目标匹配 敏感数据配置 |
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
模板中的目标匹配请看
https://docs.saltproject.io/en/latest/topics/pillar/

[root@master base]# salt 'minion01' grains.get hwaddr_interfaces:ens160
minion01:
00:0c:29:f4:b4:a9
目标匹配实例：
用Grains来匹配minion：
在所有centos系统中执行命令
[root@master base]# salt -G 'os:CentOS' test.ping
minion02:
True
//在top file里面使用Grains：
[root@master base]# pwd
/srv/salt/base
[root@master base]# vim top.sls
base:
'os:CentOS': //表示所有的centos系统都会执行要达到的状态
- match: grain
- web.nginx.nginx
[root@master base]# salt -G 'os:CentOS' state.highstate
[root@minion02 ~]# systemctl stop nginx.service
[root@minion02 ~]# systemctl status nginx.service
● nginx.service - The nginx HTTP and reverse proxy server
Loaded: loaded (/usr/lib/systemd/system/nginx.service; enabled; vendor preset: disabled)
Active: active (running) since 二 2021-11-03 11:14:54 CST; 9s ago
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）
记得重启服务，因为minion只会读取重启之前的的内容，因为我们在minion开启状态下写的所以需要重启minion服务使其读取生效
[root@minion01 ~]# vim /etc/salt/grains
system: linux
version: redhat
[root@minion01 ~]# systemctl restart salt-minion.service
[root@master base]# salt 'minion01' grains.items
swap_total:
2091
system:
linux
version:
redhat
virtual:
若不想重启也可以使用下面的方法
[root@minion01 ~]# vim /etc/salt/grains
age: 18
[root@master base]# salt 'minion01' saltutil.sync_grains
minion01:
[root@master base]# salt 'minion01' grains.get age
minion01:
18
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
//查看pillar的信息
[root@master base]# salt '*' pillar.items
minion02:
----------
minion01:
----------
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
pillar_roots:
base:
- /srv/pillar/bash
pillar_opts: True //取消注释，并将Fales改为True，这里是为了展示效果才开启，建议保持关闭状态。
[root@master ~]# systemctl restart salt-master.service
[root@master ~]# salt 'minion01' pillar.items
minion01:
----------
master:
----------
__cli:
salt-master
__role:
master
allow_minion_key_revoke:
True
指定top file入口文件
[root@master base]# pwd
/srv/pillar/base
[root@master base]# vim top.sls
base: //指定环境
'minion*': //指定目标
- apache //引用apache.sls
[root@master base]# salt '*' pillar.items
minion02:
----------
apache:
test
minion01:
----------
apache:
httpd
在salt下修改apache的状态文件，引用pillar的数据
[root@master base]# cat /srv/salt/base/web/apache/apache.sls
apache-install:
pkg.installed:
- name: {{ pillar['apache'] }}
apache-service:
service.running:
- name: {{ pillar['apache']}}
- enable: True
执行高级状态文件
[root@master base]# salt '*' state.highstate
