本文介绍了如何在Linux操作系统中的VPS上搭建WAF（Web应用防火墙），以增强网站的安全防护能力。通过开启VPS防火墙端口，有效阻挡恶意攻击，提升网站安全性能。
本文目录导读：
随着互联网的快速发展，网络安全问题日益严重，尤其是网站安全问题，网站遭受攻击的方式多种多样，如SQL注入、XSS跨站脚本攻击、文件上传漏洞等，为了保护网站免受攻击，搭建WAF（Web应用防火墙）成为了一种有效的解决方案，本文将介绍如何在VPS上搭建WAF防火墙，提升网站安全防护能力。
WAF防火墙简介
WAF（Web应用防火墙）是一种基于应用层的网络安全防护技术，主要用于检测和阻止针对Web应用的攻击行为，WAF防火墙通过分析HTTP请求，对请求内容进行过滤和检查，从而阻止恶意请求，保护Web应用免受攻击。
VPS搭建WAF防火墙步骤
1、准备工作
在搭建WAF防火墙之前，需要确保VPS系统环境满足以下要求：
（1）操作系统：建议使用Linux操作系统，如CentOS、Ubuntu等。
（2）Web服务器：如Apache、Nginx等。
（3）PHP环境：建议使用PHP 5.6及以上版本。
2、安装WAF防火墙
以下以ModSecurity为例，介绍如何在Apache服务器上安装WAF防火墙。
（1）安装Apache和PHP
安装Apache和PHP，以下以CentOS系统为例：
yum install httpd php
（2）安装ModSecurity
下载ModSecurity源码：
wget https://www.modsecurity.org/tarball/2.9.3/modsecurity-2.9.3.tar.gz
解压源码：
tar zxvf modsecurity-2.9.3.tar.gz
编译安装：
cd modsecurity-2.9.3 ./configure make make install
（3）配置ModSecurity
编辑Apache配置文件httpd.conf，添加以下内容：
LoadModule security2_module modules/mod_security2.so SecRuleEngine On SecRule(default_action, "phase:2,deny,log") SecRule REQUEST_METHOD "!(GET|POST)" chain SecRule REQUEST_URI ".*.(?:jsp|jspx|asp|aspx|php|pl)$" SecRule REQUEST_FILENAME "@rx /var/www/.*.(?:jsp|jspx|asp|aspx|php|pl)$" SecRule REQUEST_FILENAME "@rx /var/www/.*.ini$" SecRule REQUEST_FILENAME "@rx /var/www/.*.txt$" SecRule REQUEST_FILENAME "@rx /var/www/.*.log$" SecRule REQUEST_FILENAME "@rx /var/www/.*.conf$" SecRule REQUEST_FILENAME "@rx /var/www/.*.cfg$" SecRule REQUEST_FILENAME "@rx /var/www/.*.json$" SecRule REQUEST_FILENAME "@rx /var/www/.*.xml$" SecRule REQUEST_FILENAME "@rx /var/www/.*.html$" SecRule REQUEST_FILENAME "@rx /var/www/.*.css$" SecRule REQUEST_FILENAME "@rx /var/www/.*.js$" SecRule REQUEST_FILENAME "@rx /var/www/.*.jpg$" SecRule REQUEST_FILENAME "@rx /var/www/.*.png$" SecRule REQUEST_FILENAME "@rx /var/www/.*.gif$" SecRule REQUEST_FILENAME "@rx /var/www/.*.ico$" SecRule REQUEST_FILENAME "@rx /var/www/.*.swf$" SecRule REQUEST_FILENAME "@rx /var/www/.*.flv$" SecRule REQUEST_FILENAME "@rx /var/www/.*.mp3$" SecRule REQUEST_FILENAME "@rx /var/www/.*.mp4$" SecRule REQUEST_FILENAME "@rx /var/www/.*.wmv$" SecRule REQUEST_FILENAME "@rx /var/www/.*.mov$" SecRule REQUEST_FILENAME "@rx /var/www/.*.avi$" SecRule REQUEST_FILENAME "@rx /var/www/.*.zip$" SecRule REQUEST_FILENAME "@rx /var/www/.*.rar$" SecRule REQUEST_FILENAME "@rx /var/www/.*.tar$" SecRule REQUEST_FILENAME "@rx /var/www/.*.gz$" SecRule REQUEST_FILENAME "@rx /var/www/.*.bz2$" SecRule REQUEST_FILENAME "@rx /var/www/.*.7z$" SecRule REQUEST_FILENAME "@rx /var/www/.*.iso$" SecRule REQUEST_FILENAME "@rx /var/www/.*.img$" SecRule REQUEST_FILENAME "@rx /var/www/.*.pdf$" SecRule REQUEST_FILENAME "@rx /var/www/.*.doc$" SecRule REQUEST_FILENAME "@rx /var/www/.*.docx$" SecRule REQUEST_FILENAME "@rx /var/www/.*.xls$" SecRule REQUEST_FILENAME "@rx /var/www/.*.xlsx$" SecRule REQUEST_FILENAME "@rx /var/www/.*.ppt$" SecRule REQUEST_FILENAME "@rx /var/www/.*.pptx$" SecRule REQUEST_FILENAME "@rx /var/www/.*.txt$" SecRule REQUEST_FILENAME "@rx /var/www/.*.log$" SecRule REQUEST_FILENAME "@rx /var/www/.*.conf$" SecRule REQUEST_FILENAME "@rx /var/www/.*.cfg$" SecRule REQUEST_FILENAME "@rx /var/www/.*.json$" SecRule REQUEST_FILENAME "@rx /var/www/.*.xml$" SecRule REQUEST_FILENAME "@rx /var/www/.*.html$" SecRule REQUEST_FILENAME "@rx /var/www/.*.css$" SecRule REQUEST_FILENAME "@rx /var/www/.*.js$" SecRule REQUEST_FILENAME "@rx /var/www/.*.jpg$" SecRule REQUEST_FILENAME "@rx /var/www/.*.png$" SecRule REQUEST_FILENAME "@rx /var/www/.*.gif$" SecRule REQUEST_FILENAME "@rx /var/www/.*.ico$" SecRule REQUEST_FILENAME "@rx /var/www/.*.swf$" SecRule REQUEST_FILENAME "@rx /var/www/.*.flv$" SecRule REQUEST_FILENAME "@rx /var/www/.*.mp3$" SecRule REQUEST_FILENAME "@rx /var/www/.*.mp4$" SecRule REQUEST_FILENAME "@rx /var/www/.*.wmv$" SecRule REQUEST_FILENAME "@rx /var/www/.*.mov$" SecRule REQUEST_FILENAME "@rx /var/www/.*.avi$" SecRule REQUEST_FILENAME "@rx /var/www/.*.zip$" SecRule REQUEST_FILENAME "@rx /var/www/.*.rar$" SecRule REQUEST_FILENAME "@rx /var/www/.*.tar$" SecRule REQUEST_FILENAME "@rx /var/www/.*.gz$" SecRule REQUEST_FILENAME "@rx /var/www/.*.bz2$" SecRule REQUEST_FILENAME "@rx /var/www/.*.7z$" SecRule REQUEST_FILENAME "@rx /var/www/.*.iso$" SecRule REQUEST_FILENAME "@rx /var/www/.*.img$" SecRule REQUEST_FILENAME "@rx /var/www/.*.pdf$" SecRule REQUEST_FILENAME "@rx /var/www/.*.doc$" SecRule REQUEST_FILENAME "@rx /var/www/.*.docx$" SecRule REQUEST_FILENAME "@rx /var/www/.*.xls$" SecRule REQUEST_FILENAME "@rx /var/www/.*.xlsx$" SecRule REQUEST_FILENAME "@rx /var/www/.*.ppt$" SecRule REQUEST_FILENAME "@rx /var/www/.*.pptx$" SecRule REQUEST_FILENAME "@rx /var/www/.*.txt$" SecRule REQUEST_FILENAME "@rx /var/www/.*.log$" SecRule REQUEST_FILENAME "@rx /var/www/.*.conf$" SecRule REQUEST_FILENAME "@rx /var/www/.*.cfg$" SecRule REQUEST_FILENAME "@rx /var/www/.*.json$" SecRule REQUEST_FILENAME "@rx /var/www/.*.xml$" SecRule REQUEST_FILENAME "@rx /var/www/.*.html$" SecRule REQUEST_FILENAME "@rx /var/www/.*.css$" SecRule REQUEST_FILENAME "@rx /var/www/.*.js$" SecRule REQUEST_FILENAME "@rx /var/www/.*.jpg$" SecRule REQUEST_FILENAME "@rx /var/www/.*.png$" SecRule REQUEST_FILENAME "@rx /var/www/.*.gif$" SecRule REQUEST_FILENAME "@rx /var/www/.*.ico$" SecRule REQUEST_FILENAME "@rx /var/www/.*.swf$" SecRule REQUEST_FILENAME "@rx /var/www/.*.flv$" SecRule REQUEST_FILENAME "@rx /var/www/.*.mp3$" SecRule REQUEST_FILENAME "@rx /var/www/.*.mp4$" SecRule REQUEST_FILENAME "@rx /var/www/.*.wmv$" SecRule REQUEST_FILENAME "@rx /var/www/.*.mov$" SecRule REQUEST_FILENAME "@rx /var/www/.*.avi$" SecRule REQUEST_FILENAME "@rx /var/www/.*.zip$" SecRule REQUEST_FILENAME "@rx /var/www/.*.rar$" SecRule REQUEST_FILENAME "@rx /var/www/.*.tar$" SecRule REQUEST_FILENAME "@rx /var/www/.*.gz$" SecRule REQUEST_FILENAME "@rx /var/www/.*.bz2$" SecRule REQUEST_FILENAME "@rx /var/www/.*.7z$" SecRule REQUEST_FILENAME "@rx /var
