　　单个yml文件示例：

 - hosts: webservers          #主机组
   vars:                             ##变量设置
     http_port: 80
     max_clients: 200
   remote_user: root
   tasks:                            ###主要任务
   - name: ensure apache is at the latest version
     yum: pkg=httpd state=latest
   - name: write the apache config file
     template: src=/srv/httpd.j2 dest=/etc/httpd.conf
     notify:                                 ##条件触发
     - restart apache                      ##重启服务
   - name: ensure apache is running
     service: name=httpd state=started
   handlers:                                 ##在发生改变时执行的操作
     - name: restart apache
       service: name=httpd state=restarted

 ‘notify’ 下列出的即是 handlers.
