ip_hash;
server 18.14.37.69:80;
server 8.4.17.5:80;
}

server {
listen 80 default;
server_name _;
return 444;
# server_name www.***123.com ***123.com;

# return 500;
#charset koi8-r;

#access_log logs/host.access.log main;

location / {
root html;
index index.html index.htm;
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;
proxy_pass http://localhost;
}

打开nginx.conf文件，加进去下面一段话：
## Deny access to any host other than (www.).你的域名.com
server {
server_name _; #default
return 444;
}
