一、Apache
①、通过修改 .htaccess 文件
修改网站目录下的.htaccess,添加如下代码即可(2 种代码任选):
可用代码 (1):
RewriteEngine On RewriteCond %{HTTP_USER_AGENT} (^$|FeedDemon|Indy Library|Alexa Toolbar|AskTbFXTV|AhrefsBot|CrawlDaddy|CoolpadWebkit|Java|Feedly|UniversalFeedParser|ApacheBench|Microsoft URL Control|Swiftbot|ZmEu|oBot|jaunty|Python-urllib|lightDeckReports Bot|YYSpider|DigExt|HttpClient|MJ12bot|heritrix|EasouSpider|Ezooms) [NC] RewriteRule ^(.*)$ - [F]
可用代码 (2):
SetEnvIfNoCase ^User-Agent$ .*(FeedDemon|Indy Library|Alexa Toolbar|AskTbFXTV|AhrefsBot|CrawlDaddy|CoolpadWebkit|Java|Feedly|UniversalFeedParser|ApacheBench|Microsoft URL Control|Swiftbot|ZmEu|oBot|jaunty|Python-urllib|lightDeckReports Bot|YYSpider|DigExt|HttpClient|MJ12bot|heritrix|EasouSpider|Ezooms) BADBOT Order Allow,Deny Allow from all Deny from env=BADBOT
②、通过修改 httpd.conf 配置文件
找到如下类似位置,根据以下代码 新增 / 修改,然后重启 Apache 即可:
DocumentRoot /home/wwwroot/xxx <Directory "/home/wwwroot/xxx"> SetEnvIfNoCase User-Agent ".*(FeedDemon|Indy Library|Alexa Toolbar|AskTbFXTV|AhrefsBot|CrawlDaddy|CoolpadWebkit|Java|Feedly|UniversalFeedParser|ApacheBench|Microsoft URL Control|Swiftbot|ZmEu|oBot|jaunty|Python-urllib|lightDeckReports Bot|YYSpider|DigExt|HttpClient|MJ12bot|heritrix|EasouSpider|Ezooms)" BADBOT Order allow,deny Allow from all deny from env=BADBOT </Directory>
二、Nginx 代码
进入到 nginx 安装目录下的 conf 目录,将如下代码保存为 agent_deny.conf
cd /usr/local/nginx/conf
vim agent_deny.conf
#禁止Scrapy等工具的抓取
if ($http_user_agent ~* (Scrapy|Curl|HttpClient)) { return 403; }
#禁止指定UA及UA为空的访问
if ($http_user_agent ~* "FeedDemon|Indy Library|Alexa Toolbar|AskTbFXTV|AhrefsBot|CrawlDaddy|CoolpadWebkit|Java|Feedly|UniversalFeedParser|ApacheBench|Microsoft URL Control|Swiftbot|ZmEu|oBot|jaunty|Python-urllib|lightDeckReports Bot|YYSpider|DigExt|HttpClient|MJ12bot|heritrix|EasouSpider|Ezooms|^$" ) { return 403; }
#禁止非GET|HEAD|POST方式的抓取
if ($request_method !~ ^(GET|HEAD|POST)$) { return 403; }
然后,在网站相关配置中的 location / { 之后插入如下代码:
include agent_deny.conf;
如博客的配置:
[marsge@Mars_Server ~]$ cat /usr/local/nginx/conf/sulao.conf location / { try_files $uri $uri/ /index.php?$args; #这个位置新增1行: include agent_deny.conf; rewrite ^/sitemap_360_sp.txt$ /sitemap_360_sp.php last; rewrite ^/sitemap_baidu_sp.xml$ /sitemap_baidu_sp.php last; rewrite ^/sitemap_m.xml$ /sitemap_m.php last;
保存后,执行如下命令,平滑重启 nginx 即可:
/usr/local/nginx/sbin/nginx -s reload
三、PHP 代码
将如下方法放到贴到网站入口文件 index.php 中的第一个 <?php 之后即可:
PHP
//获取UA信息 $ua = $_SERVER['HTTP_USER_AGENT']; //将恶意USER_AGENT存入数组 $now_ua = array('FeedDemon ','BOT/0.1 (BOT for JCE)','CrawlDaddy ','Java','Feedly','UniversalFeedParser','ApacheBench','Swiftbot','ZmEu','Indy Library','oBot','jaunty','YandexBot','AhrefsBot','MJ12bot','WinHttp','EasouSpider','HttpClient','Microsoft URL Control','YYSpider','jaunty','Python-urllib','lightDeckReports Bot'); //禁止空USER_AGENT,dedecms等主流采集程序都是空USER_AGENT,部分sql注入工具也是空USER_AGENT if(!$ua) { header("Content-type: text/html; charset=utf-8"); die('请勿采集本站!'); }else{ foreach($now_ua as $value ) //判断是否是数组中存在的UA if(eregi($value,$ua)) { header("Content-type: text/html; charset=utf-8"); die('请勿采集本站!'); } }
//获取UA信息
$ua = $_SERVER['HTTP_USER_AGENT'];
