155.5.1. 包含文件用法

我们将下面的playbook文件分成三个文件，这样更灵活。

---
- hosts: all
  remote_user: username
  sudo: yes

  tasks:
    - yum: name=wget state=present
      when: ansible_distribution == 'CentOS' or ansible_distribution == 'Red Hat Enterprise Linux'
    - yum: name=gcc state=present
      when: ansible_distribution == 'CentOS' or ansible_distribution == 'Red Hat Enterprise Linux'
			

tasks/cenos.yml

- yum: name=wget state=present
- yum: name=gcc state=present
			

tasks/deban.yml

- apt: pkg=wget state=present
- apt: pkg=gcc state=present
			

playbook.yml

---
- hosts: all
  remote_user: username
  sudo: yes

  tasks:
    - include: tasks/centos.yml
      when: ansible_distribution == 'CentOS' or ansible_distribution == 'Red Hat Enterprise Linux'
    - include: tasks/debian.yml
      when: ansible_distribution == 'Debian' or ansible_distribution == 'Ubuntu'
