角色定制roles
角色定制实例利用角色部署wordpress
1.在roles目录下生成对应的目录结构
2.定义配置文件
①nginx
②php ③mysql
④定义剧本文件
⑤启动服务 角色定制roles 对于普通的剧本playbook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。 角色定制实例利用角色部署wordpress 192.168.134.165 server01 192.168.134.166 server02 192.168.134.163 server03 server01管理其他两个服务器资产。 1.在roles目录下生成对应的目录结构
[rootserver01 ~]# mkdir roles
#生成相应的目录
[rootserver01 roles]# ansible-galaxy init nginx
[rootserver01 roles]# ansible-galaxy init mysql
[rootserver01 roles]# ansible-galaxy init php
[rootserver01 roles]# tree

我们需要修改每个文件对应的配置。
①nginx

# vars file for mysqldb_name: wordpressdb_pass: Aren123④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
[rootserver01 roles]# vim roles.yaml
---- hosts: allremote_user: rootroles:- nginx- php- mysql
⑤启动服务
[rootserver01 roles]# ansible-playbook /root/roles/roles.yaml 进入web页面
