nginx 顶级域重定向到子域

Question

我的 nginx 配置将所有请求从 domain.ru 重定向到子域。domain.ru 我不明白为什么。这是我的配置：

    upstream upstream_server {
      server unix:/sockets/inst_site.sock fail_timeout=60s;
    }


server {
        listen 8000;
        server_name www.subdomain.domain.ru;
        return 301 $scheme://subdomain.domain.ru$request_uri;
}

server {
    listen 8000;
    server_name subdomain.domain.ru;
    #index index.html;

    location /static/ {
        autoindex off;
        root "/project/inst_site/";

        if (!-e /project/inst_site$uri) {
            rewrite    ^/static(.*)$    /static-root;
        }
    }

    location /static-root/ {
        autoindex off;
        root "/project/inst_site/";
    }

    location / {
        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;
        client_max_body_size    10m;
        client_body_buffer_size 128k;
        proxy_connect_timeout   90;
        proxy_send_timeout      90;
        proxy_read_timeout      90;
        proxy_buffers           32 4k;

            location /graphql/ {
                proxy_set_header Host localhost;
                proxy_pass http://upstream_server;
            }

            location /admin/ {
                proxy_set_header Host localhost;
                proxy_pass http://upstream_server;
            }

            autoindex off;
            root "/project/inst-ng/dist/inst-ng";
            try_files $uri $uri/ index.html;

    }
}

Nginx运行在一个容器中，暴露80端口到8000端口。没有提到"domain.ru"，为什么它仍然服务于它？

添加：事实上，它通过永久重定向响应任何子域：

curl --head http://nhnhnhnhnh.domain.ru
HTTP/1.1 301 Moved Permanently
Server: nginx/1.15.8
Date: Thu, 21 Feb 2019 21:37:57 GMT
Content-Type: text/html
Content-Length: 169
Connection: keep-alive
Location: http://subdomain.domain.ru/

Answer 1

因为您的 nginx 配置为 subdomain.domain.ru。

对 domain.ru 的请求进入 subdomain.domain.ru，其中肯定有足够的代码重定向到规范 URL，即 http://subdomain.domain.ru/
