Nginx优化——防盗链

防盗链演示

1、安装配置DNS域名解析服务

[root@localhost ~]# yum install bind -y
[root@localhost ~]# vim /etc/named.conf 

options {
        listen-on port 53 { any; };
        ...
        allow-query     { any; };

[root@localhost ~]# vim /etc/named.rfc1912.zones

zone "accp.com" IN {        type master;
        file "accp.com.zone";
        allow-update { none; };
};    

[root@localhost ~]# cd /var/named/ 
[root@localhost named]# cp -p named.localhost accp.com.zone
#复制模板文件

[root@localhost named]# vim accp.com.zone 

$TTL 1D
@       IN SOA  @ rname.invalid. (
                                        0       ; serial
                                        1D      ; refresh
                                        1H      ; retry
                                        1W      ; expire
                                        3H )    ; minimum
        NS      @
        A       127.0.0.1
www IN  A       192.168.235.158
#IP地址指向本机地址

[root@localhost named]# systemctl start named 
[root@localhost named]# systemctl stop firewalld.service
[root@localhost named]# setenforce 0

2、打开一台Win7虚拟机,搭建盗链网站。创建一个网页内容，修改后缀为index.html

 
     
 
 
     
this is test web
 
        
 

3、搭建网站


4、修改首选DNS服务器地址

5、分别访问原网站和盗链网站


6、修改Nginx.conf文件

[root@localhost named]# vim /usr/local/nginx/conf/nginx.conf

location ~*\.(jpg|gif|swf)$ { 
                #支持格式                       
                valid_referers none blocked *.accp.com accp.com;    
                #允许用accp.com为后缀访问                    
                    if ( $invalid_referer ) {      
                    #判断是否被盗链     
                        rewrite ^/ http://www.accp.com/error.png;
                        #判定被盗链就跳转错误图片
                }
}

[root@localhost named]# cp /abc/error.png /usr/local/nginx/html/
[root@localhost named]# systemctl stop nginx
[root@localhost named]# systemctl start nginx

7、再次访问盗链网页,验证防盗效果
