执行命令 #

ansible-playbook nmap.yml --ask-become-pass --tags nmap

相关配置文件内容 #

roles/debian/tasks/install_nmap.yml #

- name: install nmap
  apt:
    name: "{{ item }}"
    state: latest
  with_items: "{{ packages }}"

roles/debian/tasks/main.yml #

---
- include_tasks: install_nmap.yml
  tags: [ 'nmap' ]
  when: true

group_vars/debian.yml #

packages:
  - nmap

Ansible执行输出 #

已尝试的排查操作 #

• 修改group_vars中变量的声明方式，问题依旧
• 在角色任务中硬编码变量，未产生预期变更
• 执行过程无报错信息，无法定位问题根源
