Anisble Roles

Anisble Roles

Roles基本概述

roles不管是Ansible还是saltstack,我在写一键部署的时候,都不可能把所有的步骤全部写入到一个'剧本'文件当中,
我们肯定需要把不同的工作模块,拆分开来,解耦,那么说到解耦,我们就需要用到roles官方推荐,因为roles的目
录结构层次更加清晰。
例如:我们之前推荐大家写一个base.yml里面写所有基础优化的项目,其实把所有东西摞进去也是很鸡肋的,不如
我们把这些功能全部拆分开,谁需要使用,就调用即可。
建议:每个roles最好只使用一个tasks这样方便我们去调用,能够很好的做到解耦。(SOA)

roles 中的依赖关系

roles允许你再使用roles时自动引入其他的roles。role依赖关系存储在roles目录中meta/main.yml文件中。 例如:推送wordpress并解压,前提条件,必须要安装nginx和php,把服务跑起来,才能运行wordpress的页面, 此时我们就可以在wordpress的roles中定义依赖nginx和php的roles

[Sun Aug 22 01:45:51 root@m01 /ansible_project/roles]
 # vim wordpress/meta/main.yml 
dependencies:
  - {role: nginx}
  - {role: php}
  - {role: mariadb}
  
#举例: 如果要执行这个Wordpress 那么他走的流程是怎么样的?
首先系统会先查看/wordpress/meta/main.yml这里面的内容 是否有相关的依赖 因为wordpress需要依赖Nginx ,PHP。mariadb, 所以先到Nginx下的/meta/main.yml 去查看有没有相关的依赖,如果有继续找依赖 没有的话 就再看nginx里面的tasks里的main.yml, 这个里面一般装的是included install,config,start nginx ,如果在安装的过程中需要用到template模块中的东西 ,那么它会去nginx/template中去找相关的文件,如果找的东西是copy模块里的东西 ,那么它会去nginx/files中去找相关的文件 所以所有的文件我们都不要写绝对路径,就写文件名就行   ./ 都不需要加, nginx安装完之后 会再去查看php/meta/main.yml里的依赖关系,没有需要依赖的就会在去查看task/main.yml 是copy的就去找files里的 是templatede 就去找templates里的,安装好php之后  ,再继续去mariadb/meta/main.yml查看依赖 同理去找各个文件  要记住在执行任何任务之前 都是需要先去meta下的main.yml去查看依赖,同时注意依赖不要写成死循环,互相依赖.   找完依赖就找tasks, 执行任务过程如果用到变量 那就去vas里去看 handlers里装的是触发器
