12.13 Nginx防盗链 - 码农教程

Nginx防盗链目录概要

配置如下，可以和上面的配置结合起来

location ~* ^.+.(gif|jpg|png|swf|flv|rar|zip|doc|pdf|gz|bz2|jpeg|bmp|xls)$
{
    expires 7d;
    valid_referers none blocked server_names  *.test.com ;
    if ($invalid_referer) {
        return 403;
    }
    access_log off;
}

Nginx防盗链

Nginx防盗链配置需要和不记录日志和过期时间结合在一起，因为都用到了“location”

打开配置文件 vim /usr/local/nginx/conf/vhost/test.com.conf

注释掉一些配置

   #location ~ .*.(gif|jpg|jpeg|png|bmp|swf)$
    #{
    #      expires      7d;
    #      access_log off;
    #}

添加一些配置

location ~* ^.+.(gif|jpg|png|swf|flv|rar|zip|doc|pdf|gz|bz2|jpeg|bmp|xls)$
{
    expires 7d;        //过期时间7天
    valid_referers none blocked server_names  *.test.com ;   //定义一个白名单，referer就是指一些域名
    if ($invalid_referer) {                                        //如果不是白名单里的
        return 403;                                                   //返回403
    }
    access_log off;
}

最后结果如下

[root@hf-01 ~]# vim /usr/local/nginx/conf/vhost/test.com.conf

server
{
    listen 80;
    server_name test.com test1.com test2.com;
    root /data/wwwroot/test.com;
    if ($host != 'test.com' ) {
        rewrite  ^/(.*)$  http://test.com/$1  permanent;
    }   
    #location ~ .*.(gif|jpg|jpeg|png|bmp|swf)$
    #{
    #      expires      7d;
    #      access_log off;
    #}     
    location ~* ^.+.(gif|jpg|png|swf|flv|rar|zip|doc|pdf|gz|bz2|jpeg|bmp|xls)$
    {   
    expires 7d;
    valid_referers none blocked server_names  *.test.com ;
    if ($invalid_referer) {
        return 403;
    }   
    access_log off;
}   
    location ~ .*.(js|css)$
    {
          expires      12h;
          access_log off;
    }     
    access_log /tmp/test.com.log combined_realip;
}   
保存退出

添加的配置中的 ~* 表示不区分大小写，另外防盗链的配置里面server_names可以不写照样
检查配置文件语法错误，并重新加载配置文件

[root@hf-01 ~]# /usr/local/nginx/sbin/nginx -t
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
[root@hf-01 ~]# /usr/local/nginx/sbin/nginx -s reload
[root@hf-01 ~]#

测试

[root@hf-01 ~]# curl -x127.0.0.1:80 -I test.com/1.gif
HTTP/1.1 200 OK
Server: nginx/1.12.1

[root@hf-01 ~]#

测试防盗链，使用curl -e

[root@hf-01 ~]# curl -e "http://www.baidu.com/1.txt" -x127.0.0.1:80 -I test.com/1.gif
HTTP/1.1 403 Forbidden
Server: nginx/1.12.1
Date: Thu, 04 Jan 2018 22:51:54 GMT
Content-Type: text/html
Content-Length: 169
Connection: keep-alive

[root@hf-01 ~]# curl -e "http://www.test.com/1.txt" -x127.0.0.1:80 -I test.com/1.gif
HTTP/1.1 200 OK
Server: nginx/1.12.1
Date: Thu, 04 Jan 2018 22:52:22 GMT
Content-Type: image/gif
Content-Length: 8
Last-Modified: Thu, 04 Jan 2018 21:50:34 GMT

[root@hf-01 ~]#

再访问curl -e "http://www.baidu.com/1.txt" -x127.0.0.1:80 -I test.com/1.gif显示403，而在访问curl -e "http://www.test.com/1.txt" -x127.0.0.1:80 -I test.com/1.gif显示200，则表示防盗链配置成功
