1、定义剧本（我这里只输出序列号）
[root@libin3]# cat libin.yml
- hosts: task
gather_facts: no
tasks:
- name: fetch
shell: |
dmidecode -t 1 | grep "Serial Number" | awk -F ":" '{print $2}'
register: serial
- name: dd
shell: |
echo "{{serial.stdout}},{{inventory_hostname}}" >> libin.csv
delegate_to: localhost
2、定义清单
[root@libin3]# cat hosts [task] ip地址 [task:vars] ansible_become=yes ansible_become_method=sudo ansible_become_user=root ansible_become_password= ansible_user= ansible_password=
