NGINX子域代理通行证

Question

版本：nginx/1.2.0 || （我知道风险，它用于内部服务器）我将如何设置一个系统，17.hostname.com将其放置为 proxy_pass http://192.168.56.17:80（其中 17 将被替换为主机名之前的任何数字）

Answer 1

server_name ~^(?<subnum>[0-9]+)\.hostname\.com$;

proxy_pass http://192.168.56.$subnum;

http://nginx.org/en/docs/http/server_names.html

Answer 2

map $host $backend {

    default 1;
    ~*^(?P<number>[0-9]+)\.hostname\.com$        $number;

    # FIXME: [0-9]+ must be replaced to regex with accurate check 1..254 range
    # for example [1-9]|[1-9][0-9]|1[0-9][0-9]|2[0-4][0-9]|25[0-4] or similar

}

server {
    server_name *.hostname.com;

    location / {
        proxy_pass http://192.168.56.$backend:80;
    }

}

并记住：如果是邪恶的！！！;-)
