[LNMP]Nginx防盗链与访问控制

防盗链
1、编辑配置文件

[root@plinuxos ~]# vi /usr/local/nginx/conf/vhost/default.conf
server
{
listen 80 default_server;
server_name aaa.com;
index index.html index.htm index.php;
root /data/wwwroot/default;
access_log /tmp/default.log juispan;
location ~* ^.+\.(gif|jpg|png|swf|flv|rar|zip|doc|pdf|gz|bz2|jpeg|bmp|xls)$
{
expires 7d;
valid_referers none blocked server_names  *.aaa.com ;
if ($invalid_referer) {
return 403;
}
access_log off;
}
}

2、检查与重载

[root@plinuxos ~]# /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@plinuxos ~]# /usr/local/nginx/sbin/nginx -s reload
