便于功能的重用
本质上是文本文件，xxxx.yml, xxxx.yaml
遵循YAML语法
1、一个键对应一个值时，冒号后必须有空格
key: value
2、一个键对应多个值时
key:
value
value
key:
value
value
3、同逻辑的代码缩进必须一致，建议是4个空格

ansible执行剧本时，会自动执行一个任务，名称叫Gathering Facts。
自动调用setup模块搜集被管理机的状态数据(IP、主机名、CPU、系统版本)，统称叫Facts变量

支持在配置文件调用变量 {{ 变量名称 }}
为了分区普通文件，以.j2结尾
使用template模块推送文件，触发变量的替换
与tasks同级别
核心区别: 需要特定的条件触发
典型用法：检测配置文件变化，自动重启服务
