 roles

特点

- 目录结构清晰
- 重复调用相同的任务

tasks目录里面的查找规则: 
    先找main.yml,通过import_tasks来导入task, 
    notify去找handlers里面的main.yml里面的task,
    tmplate模块去templates目录里面找需要复制的文件

 

　　

copyfile.yml

- name: copyfile
  template: src=nginx.conf.j2  dest=/etc/nginx/nginx.conf
  notify: restart

start.yml

- name: start 
  service: name=nginx state=started

 install.yml

- name: install{{pkg}}
　yum: name={{ pkg }}

main.yml

- import_tasks: install.yml
- import_tasks: copyfile.yml
- import_tasks: start.yml

port.yml

- hosts: port
  remote_user: root
  roles: 
    - port   

var/main.yml

pkg: redis

handlers/main.yml

- name: restart
  service: name=nginx state=restarted
