How to configure anti-leech in nginx
1. The principle of hotlinking
1.1 Web page preparation
Web source host (192.168.153.20) configuration
cd /usr/local/nginx/html
将preview.jpg图片文件传到/usr/local/nginx/html目录下
vim index.html
......
<img src="preview.jpg"/>
</body>
</html>
echo "192.168.153.20 www.wt.com" >> /etc/hosts
echo "192.168.153.10 www.abc.com" >> /etc/hosts
Hotlink website host (192.168.153.20) configuration
为了区别于源主机的 nginx 服务，盗链主机使用一般的wed服务即可
yum install -y httpd
vim /var/www/html/index.html
<html><body><h1>Hello！</h1>
<img src="http://www.wt.com/preview.jpg"/>
</body></html>
echo "192.168.153.20 www.wt.com" >> /etc/hosts
echo "192.168.153.10 www.abc.com" >> /etc/hosts
systemctl restart httpd
1.2 Browser access verification
Two, configure anti-theft chain
2.1 Modify the configuration file
vim /usr/local/nginx/conf/nginx.conf
http {
......
server {
......
location ~* \.(jip|gif|swf)$ {
valid_referers *.wt.com wt.com;
if ( $invalid_referer ) {
rewrite ^/ http://www.wt.com/error.png;
#return 403;
}
}
......
}
}
. ~ * (Jpg | gif | swf) $: This regular expression matching is case-insensitive representation, in .jpg or .gif or .swf files ending;
valid_referers: Set a trusted site, you can use the normal picture;
later URL or domain name: the URL containing the relevant string in the referer;
if statement: if the source domain of the link is not in the list listed in valid_referers, and $invalid_referer is 1, then perform the following operation, that is, rewrite or return to the 403 page .
Transfer the error.png image file to the /usr/local/nginx/html directory
2.2 Browser access verification
