Saltstack_实战指南02_各主机Pillar信息指定

1. 实战项目GitHub地址

该项目已经放在了GitHub上，地址如下：

https://github.com/zhanglianghhh/salt-example-lnmp

2. 主机规划

3. pillar的整体目录结构

 [root@salt150-master pillar]# pwd
 /srv/pillar
 [root@salt150-master pillar]# ll
 total
 drwxr-xr-x  root root   Mar  : base
 drwxr-xr-x  root root   Mar  : prod
 -rw-r--r--  root root  Mar  : top.sls
 [root@salt150-master pillar]# tree
 .
 ├── base
 │   ├── database.sls
 │   ├── monitor.sls
 │   └── nosql.sls
 ├── prod
 │   ├── high_available.sls
 │   ├── program.sls
 │   ├── proxy.sls
 │   └── web.sls
 └── top.sls

  directories,  files

4. Pillar的top.sls 文件信息

 [root@salt150-master pillar]# cat top.sls
 base:
   '*':
     # base 目录
     - base.database
     - base.nosql
     - base.monitor
     # prod 目录
     - prod.web
     - prod.program
     - prod.proxy
     - prod.high_available

5. base基础信息

 [root@salt150-master base]# pwd
 /srv/pillar/base
 [root@salt150-master base]# ll
 total
 -rw-r--r--  root root  Mar  : database.sls
 -rw-r--r--  root root  Mar  : monitor.sls
 -rw-r--r--  root root   Mar  : nosql.sls
 [root@salt150-master base]# cat database.sls
 # 数据库信息
 # 包含配置文件信息
 # 注意和 zabbix pillar 不同 的写法
 {% if grains['host'] == 'salt03-web' %}
 database_info:
   database: mysql
   role: master
   server-id:
   read_only: "OFF"
 {% elif grains['host'] == 'salt04-web' %}
 database_info:
   database: mysql
   role: slave
   server-id:
   read_only: "ON"
 {% elif grains['host'] == 'salt05-web' %}

 {% endif %}

 [root@salt150-master base]# cat nosql.sls
 # nosql 信息
 {% if grains['host'] == 'salt05-web' %}
 nosql_info:
   nosql: memcached
 {% endif %}

 [root@salt150-master base]# cat monitor.sls
 # 其中 salt150-maste 172.16.1.150 机器，不仅是 zabbix 客户端，还是服务端
 # 只包含 zabbix 的属性 【服务端 客户端】
 monitor_info:
   monitor:
     {% if grains['host'] == 'salt150-master' %}
     zabbix_server: True
     {% endif %}
     zabbix_agent: True
     zabbix_server_hostname: 'salt150-master'

6. prod业务组件信息

 [root@salt150-master prod]# pwd
 /srv/pillar/prod
 [root@salt150-master prod]# ll
 total
 -rw-r--r--  root root  Mar  : high_available.sls
 -rw-r--r--  root root  Mar  : program.sls
 -rw-r--r--  root root  Mar  : proxy.sls
 -rw-r--r--  root root  Mar  : web.sls
 [root@salt150-master prod]# cat web.sls
 # web 服务器
 {% if grains['host'] == 'salt03-web' or grains['host'] == 'salt04-web' or grains['host'] == 'salt05-web' %}
 web_info:
   web: nginx
 {% endif %}

 [root@salt150-master prod]# cat program.sls
 # 使用的编程语言
 {% if grains['host'] == 'salt03-web' or grains['host'] == 'salt04-web' or grains['host'] == 'salt05-web' %}
 program_info:
   program: php
 {% endif %}

 [root@salt150-master prod]# cat proxy.sls
 # 负载均衡服务器
 {% if grains['host'] == 'salt01-haproxy' or grains['host'] == 'salt02-haproxy' %}
 proxy_info:
   proxy: haproxy
 {% endif %}

 [root@salt150-master prod]# cat high_available.sls
 # 高可用keepalived 的 pillar 信息
 {% if grains['host'] == 'salt01-haproxy' %}
 high_available_info:
   high_available: keepalived
   high_state: MASTER
   high_priority:
 {% elif grains['host'] == 'salt02-haproxy' %}
 high_available_info:
   high_available: keepalived
   high_state: BACKUP
   high_priority:
 {% endif %}

7. pillar信息生效

 [root@salt150-master pillar]# salt '*' saltutil.refresh_pillar
 salt02-haproxy:
     True
 salt01-haproxy:
     True
 salt05-web:
     True
 salt03-web:
     True
 salt150-master:
     True
 salt04-web:
     True
