一、部署nginx
cd /opt
mkdir nginx
cd nginx/
上传nginx.repo、nginx.conf，并且修改nginx.conf为nginx.conf.j2
vim nginx.conf.j2

二、Roles 模块
roles用于层次性、结构化地组织playbook。roles能够根据层次型结构自动装载变量文件、tasks以及handlers等。要使用roles只需要在playbook中使用include指令引入即可。
简单来讲，roles就是通过分别将变量、文件、任务、模板及处理器放置于单独的目录中，并可以便捷的include它们的一种机制。roles一般用于基于主机构建服务的场景中，但也可以是用于构建守护进程等场景中。主要使用场景代码复用度较高的情况下。roles 内各目录含义解释
●files
用来存放由 copy 模块或 script 模块调用的文件。
●templates
用来存放 jinjia2 模板，template 模块会自动在此目录中寻找 jinjia2 模板文件。
●tasks
此目录应当包含一个 main.yml 文件，用于定义此角色的任务列表，此文件可以使用 include 包含其它的位于此目录的 task 文件。
●handlers
此目录应当包含一个 main.yml 文件，用于定义此角色中触发条件时执行的动作。
●vars
此目录应当包含一个 main.yml 文件，用于定义此角色用到的变量。
●defaults
此目录应当包含一个 main.yml 文件，用于为当前角色设定默认变量。 这些变量具有所有可用变量中最低的优先级，并且可以很容易地被任何其他变量覆盖。所以生产中我们一般不在这里定义变量
●meta
此目录应当包含一个 main.yml 文件，用于定义此角色的元数据信息及其依赖关系。
