WhatWeb是一个识别网站CMS的工具，其在KALI上是内置的，无需安装，但如果你想在自己的vps上安装这玩意，那我这篇文章你可以继续看下去了。WhatWeb是基于ruby语言开发的，所有在安装该工具之前我们需要先安装rubygems与bundler。
gems && bundler 介绍
gems : RubyGems 是 Ruby 的一个包管理器，它提供一个分发 Ruby 程序和库的标准格式，还提供一个管理程序包安装的工具,它可以方便地管理 gem 安装的工具，以及用于分发 gem 的服务器。这类似于 Ubuntu 下的apt-get, Centos 的 yum，Python 的 pip。这很生动形象吧！ bundler : bundler是一个很好的管理ruby项目gems的工具。当然也是一个ruby gem。使用bundler可以为你的ruby project提供统一的构建环境(无论是production, development, 还是staging)，因为bunder可以很好的跟踪和安装指定的和预期的gem。
环境部署
安装ruby环境
代码语言：javascript复制yum updata
yum install ruby ruby-devel rubygems
ruby -v # 查看ruby版本
gem -v # 查看ruby的gem包管理器版本安装bundler,这里主要安装bunder需要指定ruby的版本，不然会安装失败！！！这里是ruby官网，这里你可以选择相关版本：rubygems.org
代码语言：javascript复制gem install bundler -v 1.17.3
bundler -v # 查看该版本 部署whatweb
代码语言：javascript复制midir whatweb
cd whatweb
wget https://github.com/urbanadventurer/WhatWeb/archive/refs/tags/v0.5.5.tar.gz
tar -xzvf whatweb
cd whatweb
bundler install
./whatweb --version # 查看版本，看是否安装成功
./whatweb --help # 查看相关使用方法相关使用参数列表
