标题: nginx限制搜索引擎爬虫频率设置
Nginx限制搜索引擎爬虫频率、禁止屏蔽网络爬虫配置示例,限制爬虫频率用于一些无良爬虫,禁止爬虫用于一些不需要收录的网站,需要的会员可以参考下
代码如下:

#全局配置
limit_req_zone $anti_spider zone=anti_spider:10m rate=15r/m;
#某个server中
limit_req zone=anti_spider burst=30 nodelay;
if ($http_user_agent ~* "xxspider|xxbot") {
set $anti_spider $http_user_agent;
}
超过设置的限定频率，就会给spider一个503。
上述配置详细解释请自行google下，具体的spider/bot名称请自定义。

附：nginx中禁止屏蔽网络爬虫
代码如下:

server {
      listen    80;
      server_name  www.xxx.com;

      #charset koi8-r;

      #access_log  logs/host.access.log  main;

      #location / {
      # root html;
      # index  index.html index.htm;
      #}
if ($http_user_agent ~* "qihoobot|Baiduspider|Googlebot|Googlebot-Mobile|Googlebot-Image|Mediapartners-Google|Adsbot-Google|Feedfetcher-Google|Yahoo! Slurp|Yahoo! Slurp China|YoudaoBot|Sosospider|Sogou spider|Sogou web spider|MSNBot|ia_archiver|Tomato Bot") {
            return 403;
      }

location ~ ^/(.*)$ {
            proxy_pass http://localhost:8080;
      proxy_redirect       off;
      proxy_set_header       Host $host;
      proxy_set_header       X-Real-IP $remote_addr;
      proxy_set_header    X-Forwarded-For $proxy_add_x_forwarded_for;
      client_max_body_size 10m;
      client_body_buffer_size 128k;
      proxy_connect_timeout 90;
      proxy_send_timeout    90;
      proxy_read_timeout    90;
      proxy_buffer_size    4k;
      proxy_buffers          4 32k;
      proxy_busy_buffers_size 64k;
      proxy_temp_file_write_size 64k;
}

      #error_page  404             /404.html;

      # redirect server error pages to the static page /50x.html
      #
      error_page 500 502 503 504  /50x.html;
      location = /50x.html {
         root html;
      }

      # proxy the PHP scripts to Apache listening on 127.0.0.1:80
      #
      #location ~ \.php$ {
      # proxy_pass http://127.0.0.1;
      #}

      # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
      #
      #location ~ \.php$ {
      # root          html;
      # fastcgi_pass 127.0.0.1:9000;
      # fastcgi_index  index.php;
      # fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
      # include       fastcgi_params;
      #}

      # deny access to .htaccess files, if Apache's document root
      # concurs with nginx's one
      #
      #location ~ /\.ht {
      # deny  all;
      #}
}

可以用 curl 测试一下

代码如下:
curl -I -A "qihoobot" www.xxx.com
