ansible实现集群节点信息收集

之前写了一篇关于收集服务器硬件信息的博文，详见服务器硬件常用信息查询脚本 ，除使用脚本可以收集外，也可以使用ansible来实现资源收集。

准备ansible剧本

#cat collectinfo.yaml 
- hosts: all
  tasks:
  - name: collect info   
    template: src=./info.j2 dest=/info.txt
  - name: collect file
    fetch: src=/info.txt dest=./collections/
  - name: delete remote file
    command: rm -f /info.txt

在当前目录下新建collections目录，用于存放收集回的信息

模板文件

hostname: {{ ansible_hostname }}
product name: {{ ansible_product_name }}
product serial: {{ ansible_product_serial }}
system: {{ ansible_distribution }} {{ ansible_distribution_version }}
kernel: {{ ansible_kernel }}
CPU count: {{ ansible_processor_count }}  {{ ansible_processor_cores }} cores
total memory:{{ ansible_memtotal_mb }} MB
IP Address: {{ ansible_all_ipv4_addresses }}

执行脚本

# ansible-playbook collectinfo.yaml 

执行后的文件目录

[root@node01 simple_book]# tree
.
├── collectinfo.yaml
├── collections
│   ├── node01
│   │   └── info.txt
│   ├── node02
│   │   └── info.txt
│   └── node03
│       └── info.txt
└── info.j2

验证：

# cat collections/node02/info.txt 
hostname: node02

product serial: VMware-56 4d 43 50 c5 12 0d ae-28 bd 3b 60 89 6c fd f0
