一般我们购买到VPS服务器之后肯定需要检查当前VPS主机的配置是不是和我们购买时候商家说的一样配置，以及我们需要检查当前服务器的基本硬件稳定信息。然后加以我们使用建站或者项目用途的实际速度体验才是一个较为完整的服务器性能检测。在这篇文章中，将整理和分享这个一键脚本，可以用于检查服务器的信息。

第一、脚本地址

脚本：http://blog.xiaoyangge.com/tools/vpsinfo.sh

第二、脚本应用

wget http://blog.xiaoyangge.com/tools/vpsinfo.sh && sh vpsinfo.sh

第三、使用演示

这里我们可以看到，直接可以检测到当前服务器的IP地址、系统、发行版本、OPENVZ或者KVM，以及内存、硬盘等信息，其中还有检测到来自CACHEFIY的下载文件速度。
