Asible 批量跑出服务器相关信息

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=

3、执行ansible任务

[root@libin3]# ansible-playbook -i hosts task libin.yaml
