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
