DevOps始于"敏捷系统管理"一文。 2008年, 安德鲁（Andrew Shafer）发表了"敏捷基础（Agile Infrastucture）" 的演讲，意图解决许多开发者和公司遇到的类似问题。
2009年，帕特里克（Patrick Debois）创立了"DevOpsDays"会议来推广DevOps的概念。然而，直到谷歌发布2010年趋势盘点一文后，人们才开始把DevOps当成一项独立的概念。
如今，DevOps的概念已经不止于开发、系统管理和基础，它包括开发、运维、敏捷、云、开源和商业化等等。
DevOps在不断演变。目前，DevOps不存在认证、角色、系列工具或是固定流程。没有规范，也不是一个产品或是职位的名称。没有一种权威的说法能定义DevOps是什么或不是什么。它关乎于态度、思想、习惯、行为、文化、范式、哲学。它是一种思考、行动、存在的方式。实践就是最好的布道。践行DevOps是一场对话，你将采取最佳的方式实践并将经验分享给他人。
以下有一些已经被验证有效的非常重要的质量标准、指导原则、技术要点，每个人都应该了解。从它们开始实践DevOps会是最好的尝试。

This process requires that you are able to ssh OR log in locally using the root user account and that no services be running as users out of /home on the target machine.
The examples are from a default installation with no customization-you NEED to know what you're working with for volumes/partitions to not horribly break things.
By default, CentOS 7 uses XFS for the file system and Logical Volume Manager (LVM), creating 3 partitions: /,/home and swap.
NOTE: If you want to be sure that nothing is writing to /home you can either modify the host to boot into single-user mode OR try to use the
systemctl isolate runlevel1.target command to switch (not tested! should work).

| " The 'complete' option controls where the keywords are searched (include files, tag files, buffers, and more). | |
| " The 'completeopt' option controls how the completion occurs (for example, whether a menu is shown). | |
