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：
Shell
- 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)$) {
- return 403;
- }
然后，在网站相关配置中的 location / { 之后插入如下代码：
Shell
- include agent_deny.conf;
如下的配置：
Shell
- [marsge@Mars_Server ~]$ cat /usr/local/nginx/conf/zhangge.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：
Shell
- /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
