来自推荐人的Nginx块

valid_referers解决方案有效,但就我个人而言,很难以这种方式维持长黑名单.另一种解决方案是使用ngx_http_map_module模块.在ubuntu 14.04 nginx发行版下,你可以创建一个/etc/nginx/blacklist.conf文件:

# /etc/nginx/blacklist.conf

map $http_referer $bad_referer {
    hostnames;

    default                           0;

    # Put regexes for undesired referers here
    "~social-buttons.com"             1;
    "~semalt.com"                     1;
    "~kambasoft.com"                  1;
    "~savetubevideo.com"              1;
    "~descargar-musica-gratis.net"    1;
    "~7makemoneyonline.com"           1;
    "~baixar-musicas-gratis.com"      1;
    "~iloveitaly.com"                 1;
    "~ilovevitaly.ru"                 1;
    "~fbdownloader.com"               1;
    "~econom.co"                      1;
    "~buttons-for-website.com"        1;
    "~buttons-for-your-website.com"   1;
    "~srecorder.co"                   1;
    "~darodar.com"                    1;
    "~priceg.com"                     1;
    "~blackhatworth.com"              1;
    "~adviceforum.info"               1;
    "~hulfingtonpost.com"             1;
    "~best-seo-solution.com"          1;
    "~googlsucks.com"                 1;
    "~theguardlan.com"                1;
    "~i-x.wiki"                       1;
    "~buy-cheap-online.info"          1;
    "~Get-Free-Traffic-Now.com"       1;
}

然后将其包含在/etc/nginx/nginx.conf文件中:

# /etc/nginx/nginx.conf


    http {
    # ...

      include blacklist.conf;

    # ...

    }

完成后,您可以检查$bad_referernginx站点中的条件:

# /etc/nginx/sites-enabled/mysite.conf

server {
  # ...

  if ($bad_referer) { 
    return 444; 
  } 

  # ...
}

要确保这些东西有效,您可以在shell中执行类似的命令:

$ curl --referer http://www.social-buttons.com https://example.org

......应该给你:

curl: (52) Empty reply from server
