角色订制：roles

① 简介

对于以上所有的方式有个弊端就是无法实现复用假设在同时部署Web、db、ha 时或不同服务器组合不同的应用就需要写多个yml文件。很难实现灵活的调用。　　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指令即可。简单来讲，roles就是通过分别将变量(vars)、文件(file)、任务(tasks)、模块(modules)及处理器(handlers)放置于单独的目录中，并可以便捷地include它们的一种机制。角色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。

② 角色集合

角色集合：roles/ mysql/ httpd/ nginx/ files/：存储由copy或script等模块调用的文件； tasks/：此目录中至少应该有一个名为main.yml的文件，用于定义各task；其它的文件需要由main.yml进行“包含”调用； handlers/：此目录中至少应该有一个名为main.yml的文件，用于定义各handler；其它的文件需要由main.yml进行“包含”调用； vars/：此目录中至少应该有一个名为main.yml的文件，用于定义各variable；其它的文件需要由main.yml进行“包含”调用； templates/：存储由template模块调用的模板文本； meta/：此目录中至少应该有一个名为main.yml的文件，定义当前角色的特殊设定及其依赖关系；其它的文件需要由main.yml进行“包含”调用； default/：此目录中至少应该有一个名为main.yml的文件，用于设定默认变量；

修改变量文件

[root@localhost roles]# vim    nginx/vars/main.yml

# vars file for nginxnginx_user: rootnginx_port: 80

放置我们所需要的文件到指定目录

直接 cp /root/nginx.conf  /root/roles/nginx/templates/nginx.conf
也可以直接写
[root@localhost roles]# vim nginx/templates/nginx.conf

定义剧本文件

接下来，我们就来定义剧本文件，由于大部分设置我们都单独配置在了roles里面，所以，接下来剧本就只需要写一点点内容即可：

[root@localhost roles]# vim roles.yml
