如何在 CentOS 上的 Nginx 中将子域名重定向到根域名？

我使用的是 Centos 和 Nginx 以及 Puma。我想将所有子域名重定向到我的主根域名，因此我按照这里的说明操作——https://stackoverflow.com/questions/26801479/nginx-redirect-all-subdomains-to-main-domain。但是我无法让它工作。以下是我的配置

upstream projecta {
  server unix:///home/rails/projecta_production/shared/sockets/puma.sock;
}

server {
  listen 80;
  server_name mydomein.com;
  return 301 http://mydomein.com$request_uri;
  root /home/rails/projecta_production/public; # I assume your app is located at this location

  location / {
    proxy_pass http://projecta; # match the name of upstream directive which is defined above
    proxy_set_header Host $host;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
  }

  location ~* ^/assets/ {
    # Per RFC2616 - 1 year maximum expiry
    expires 1y;
    add_header Cache-Control public;

    # Some browsers still send conditional-GET requests if there's a
    # Last-Modified header or an ETag header even if they haven't
    # reached the expiry date sent in the Expires header.
    add_header Last-Modified "";
    add_header ETag "";
    break;
  }
}

如果我排除“返回 301http://mydomein.com$request_uri;” 行，那么我的网站将在根域上运行，但不能在任何子域上运行（例如，查看子域将产生默认的 Nginx 索引页）。如何将所有子域重定向到我的主域并保留我的 Rails/Puma 配置？

您目前正在监听顶点域虚拟主机的重定向。您需要做的是有一个单独的虚拟主机监听器来重定向到顶点。这是重定向到顶点域定义的通配符监听器的示例：

upstream projecta {
  server unix:///home/rails/projecta_production/shared/sockets/puma.sock;
}

# Listener for all subdomains
server {
  listen 80;
  server_name *.mydomein.com;
  # If you want to redirect all requests, not just subdomains, use below config instead.
  # server_name _;
  return 301 http://mydomein.com$request_uri;
}

# Listener for Apex Domain
server {
  listen 80;
  server_name mydomein.com;
  root /home/rails/projecta_production/public; # I assume your app is located at this location

  location / {
    proxy_pass http://projecta; # match the name of upstream directive which is defined above
    proxy_set_header Host $host;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
  }

  location ~* ^/assets/ {
    # Per RFC2616 - 1 year maximum expiry
    expires 1y;
    add_header Cache-Control public;

    # Some browsers still send conditional-GET requests if there's a
    # Last-Modified header or an ETag header even if they haven't
    # reached the expiry date sent in the Expires header.
    add_header Last-Modified "";
    add_header ETag "";
    break;
  }
}
