SaltStack技术入门与实战

序言 When I started writing SaltStack I wanted to create a system that would be useful in many vast scenarios.A system that would be able to scale to any need,small or large,and a system that would allow people to better automate processes far beyond the datacenter. To my knowledge,this is the first book on Salt to be published in China.I hope the contents of this book will prove valuable to those in China seeking to learn Salt Stack and that this book will be a resource to them. China SaltStack User Group has been lead for many years by talented individuals who I would like to express my thanks and gratitude to.The Chinese users and contributors to Salt have helped the project move forward in immeasurable ways! 【译文】 当我开始SaltStack项目的时候，其实是想构建一个多种复杂环境均可用的（运维配置管理）系统，可以做到按需扩展，环境可大可小，能够真正帮助数据中心更好地实现自动化运维流程。 据我所知，本书是中国地区的关于SaltStack的第一本书籍。我希望本书的出版可以帮助中国地区那些正在苦寻SaltStack学习之路的朋友们。 中国SaltStack用户组（http://www.saltstack.cn/）自成立以来，持续地为社区做出了杰出贡献，来自中国的用户和参与者为推动SaltStack项目的发展起到了不可估量的作用，在此，我深表感谢和感激！ Thomas S.Hatch SaltStack公司创始人兼CTO 前言 为什么用SaltStack 常规运维很大一部分工作涉及业务的配置管理和状态维护，目前，基于状态（系统状态、代码状态、配置状态和进程状态）的配置管理已经得到极大发展，并且让运维有了很大的进步；出现了各种工 具和平台，从最早的......
