## 一、ansible--playbook介绍 ##

playbook是由一个或多个”play”组成的列表。play的主要功能在于将事先归为一组的主机装扮成事先通过ansible中的task定义好的角色。从根本上来将，所谓的task无法是调用ansible的一个module。将多个paly组织在一个playbook中，即可以让他们联通起来按事先编排的机制同唱一台大戏。

1、playbook基础组件：

hosts playbook中的每一个paly的目的都是为了让某个或某些以某个指定用户的身份执行任务。hosts用于指定要执行指定任务的主机，其可以是一个或多个由冒号分割主机组。

user remote\_user则用于指定远程主机上的执行任务的用户。

任务列表：

play的主体部分是task list. task list中的各任务按次序逐个在hosts中指定的所有主机上执行，即在所有主机上完成第一个任务后再开始第二个。

action：任务执行过程

handlers：用于当前关注的资源发生变化时采取一定指定的操作
