VPS搭建SSH，从零开始的全指南

如果你是刚开始接触VPS（虚拟专用服务器）和SSH（安全Chef连接），那么这篇文章将是你最好的入门指南，VPS和SSH是现代云计算中非常基础但又至关重要的组成部分，尤其对于Web开发、服务器管理以及网络安全来说,掌握它们将是你的一大利器。

什么是VPS？

VPS，全称是Virtual Private Server，直译为“虚拟专用服务器”，是一种虚拟化的服务器环境，与物理服务器不同，VPS实际上是一台物理服务器，但你只需要使用其中的一部分资源，比如内存、存储、带宽等，这样，你可以按需调整资源,而不用为其他用户占用的资源支付费用。

为什么要选择VPS？

1. 成本-effective：按需付费,资源灵活。
2. 快速部署：适合快速搭建网站或应用。
3. 安全性：隔离性强,适合敏感应用。
4. 扩展性：可以根据需求添加资源。

如何选择VPS服务提供商？
