nginx – 无效的子域被重定向到另一个域

我在同一台服务器上托管了两个域.在DNS记录中,我有通配符(*)两个域的记录都指向服务器.

所以我期待xyz.domain1.com解析为domain1.com
和xyz.domain2.com到domain2.com.

但是目前除了domain2.com上的www子域之外的所有内容都将重定向到domain1.com.

我为这两个域提供了相同的nginx配置,所以我不明白是什么原因引起的.这是我的nginx配置看起来像 –

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;

        location / {

        }
    }

如何将域保持分离,以便每个域的子域都重定向到正确的域？
