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
1 [[email protected] pillar]# pwd 2 /srv/pillar 3 [[email protected]master pillar]# ll 4 total 4 5 drwxr-xr-x 2 root root 62 Mar 10 17:27 base 6 drwxr-xr-x 2 root root 83 Mar 10 17:39 prod 7 -rw-r--r-- 1 root root 183 Mar 10 17:42 top.sls 8 [[email protected]master pillar]# tree 9 . 10 ├── base 11 │ ├── database.sls 12 │ ├── monitor.sls 13 │ └── nosql.sls 14 ├── prod 15 │ ├── high_available.sls 16 │ ├── program.sls 17 │ ├── proxy.sls 18 │ └── web.sls 19 └── top.sls 20 21 2 directories, 8 files
4. Pillar的top.sls 文件信息
1 [[email protected] pillar]# cat top.sls 2 base: 3 ‘*‘: 4 # base 目录 5 - base.database 6 - base.nosql 7 - base.monitor 8 # prod 目录 9 - prod.web 10 - prod.program 11 - prod.proxy 12 - prod.high_available
5. base基础信息
1 [[email protected] base]# pwd 2 /srv/pillar/base 3 [[email protected]master base]# ll 4 total 12 5 -rw-r--r-- 1 root root 258 Mar 10 17:27 database.sls 6 -rw-r--r-- 1 root root 272 Mar 10 17:20 monitor.sls 7 -rw-r--r-- 1 root root 99 Mar 10 17:25 nosql.sls 8 [[email protected] base]# cat database.sls 9 # 数据库信息 10 # 包含配置文件信息 11 # 注意和 zabbix pillar 不同 的写法 12 {% if grains[‘host‘] == ‘salt03-web‘ %} 13 database_info: 14 database: mysql 15 role: master 16 server-id: 1 17 read_only: "OFF" 18 {% elif grains[‘host‘] == ‘salt04-web‘ %} 19 database_info: 20 database: mysql 21 role: slave 22 server-id: 2 23 read_only: "ON" 24 {% elif grains[‘host‘] == ‘salt05-web‘ %} 25 database_info: 26 database: mysql 27 role: slave 28 server-id: 3 29 read_only: "ON" 30 {% elif grains[‘host‘] == ‘salt150-master‘ %} 31 database_info: 32 database: mariadb 33 read_only: "OFF" 34 {% endif %} 35 36 [[email protected]lt150-master base]# cat nosql.sls 37 # nosql 信息 38 {% if grains[‘host‘] == ‘salt05-web‘ %} 39 nosql_info: 40 nosql: memcached 41 {% endif %} 42 43 [[email protected] base]# cat monitor.sls 44 # 其中 salt150-maste 172.16.1.150 机器,不仅是 zabbix 客户端,还是服务端 45 # 只包含 zabbix 的属性 【服务端 客户端】 46 monitor_info: 47 monitor: 48 {% if grains[‘host‘] == ‘salt150-master‘ %} 49 zabbix_server: True 50 {% endif %} 51 zabbix_agent: True 52 zabbix_server_hostname: ‘salt150-master‘
6. prod业务组件信息

7. pillar信息生效
1 [[email protected] pillar]# salt ‘*‘ saltutil.refresh_pillar 2 salt02-haproxy: 3 True 4 salt01-haproxy: 5 True 6 salt05-web: 7 True 8 salt03-web: 9 True 10 salt150-master: 11 True 12 salt04-web: 13 True
8. pillar信息查看
