ansible安装配置与简单使用
前言：AnsibleWorks成立于2012年，由自动化工具Cobbler及Func的开发者Michael DeHaan创建。其Ansible平台是一个开源的配置及计算机管理平台。可实现多节点的软件部署，执行特定任务并进行配置管理。Ansible 跟其他IT自动化技术的区别在于其关注点并非配置管理、应用部署或IT流程工作流，而是提供一个统一的界面来协调所有的IT自动化功能，因此 Ansible的系统更加易用，部署更快。受管理的节点无需安装额外的远程控制软件，由平台通过SSH（Secure SHell）对其进行管理，因此十分方便。其模块支持JSON等标准输出格式，可采用任何编程语言重写。Ansible可以让用户避免编写脚本或代码来管理应用，同时还能搭建工作流实现IT任务的自动化执行。IT自动化可以降低技术门槛及对传统IT的依赖，从而加快项目的交付速度。ansible有如下优点：1、轻量级，他不需要去客户端安装agent，更新时，只需要在操作机上进行一次更新即可
2、批量任务执行可以写成脚本，而且不用分发到远程就可以执行
3、使用python编写的，维护更简单
4、支持sudo 摘抄自网络
