无效子域名被重定向到另一个域名

无效子域名被重定向到另一个域名

我有两个域名托管在同一台服务器上。在 DNS 记录中，我为两个域名都设置了通配符 (*) A 记录，它们都指向该服务器。

因此我希望xyz.domain1.com解决domain1.com 并xyz.domain2.com解决domain2.com。

但是目前除www子域名之外的所有内容domain2.com都重定向到domain1.com。

这两个域的 nginx 配置相同，所以我不明白是什么原因造成的。我的 nginx 配置如下：

user  nginx;
worker_processes  1;

error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;

events {
    worker_connections  1024;
}

http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                    '$status $body_bytes_sent "$http_referer" '
                    '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /dev/stdout  main;
    sendfile        on;
    keepalive_timeout  65;

    # Listen for non-HTTPS requests and redirect them to HTTPS
    server {
        server_name www.domain1.com domain1.com;
        return 301 https://domain1.com$request_uri;
    }

    # Listen for www requests with HTTPS and redirect them to non www site 
    server {
        listen 443 ssl;
        server_name www.domain1.com;

    }

    # Listen for non-www HTTPS requests and serve the app
    server {
        listen              443 ssl;
        #add_header Strict-Transport-Security "max-age=31536000; includeSubDomains" always;
        server_name         domain1.com api.domain1.com;

            root   /usr/share/nginx/html;
            allow all;
        }

        location / {
            root /var/www/domain1;
        }
    }




    # Listen for non-HTTPS requests and redirect them to HTTPS
    server {
        server_name www.domain2.com domain2.com;
        return 301 https://domain2.com$request_uri;
    }

    # Listen for www requests with HTTPS and redirect them to non www site
    server {
        listen 443 ssl;
        server_name www.domain2.com;
        ssl_certificate     /etc/letsencrypt/live/www.domain2.com/fullchain.pem;
        ssl_certificate_key /etc/letsencrypt/live/www.domain2.com/privkey.pem;
        ssl_protocols       TLSv1 TLSv1.1 TLSv1.2;
        ssl_ciphers         HIGH:!aNULL:!MD5;
        return 301 https://domain2.com$request_uri;
    }


    # Listen for non-www HTTPS requests and serve the app
    server {
        listen              443 ssl;
        #add_header Strict-Transport-Security "max-age=31536000; includeSubDomains" always;
        server_name         domain2.com;
        ssl_certificate     /etc/letsencrypt/live/www.domain2.com/fullchain.pem;
        ssl_certificate_key /etc/letsencrypt/live/www.domain2.com/privkey.pem;
        ssl_protocols       TLSv1 TLSv1.1 TLSv1.2;
        ssl_ciphers         HIGH:!aNULL:!MD5;

        location ^~ /.well-known/ {
            root   /usr/share/nginx/html;
            allow all;
        }

        location / {
            root /var/www/domain2;
        }
    }
}

我如何才能保持域名分离，以便每个子域名重定向到正确的域名？

答案1

您必须为每个域添加一个通配符 server_name 条目，以选择要重定向到哪个域。否则，未知的 server_name 将被分派到第一个条目（在本例中，重定向到 domain1.com）。

添加*.domain2.com到行中server_name www.domain2.com，它应该正确分离 domain2.com 子域。
