子域名在 nginx 中不起作用

我正在尝试设置一个具有一个域和一个子域（example.com和download.example.com）的 nginx Web 服务器。

server {
    listen 80;
    listen [::]:80;

    root /var/www/html;

    index index.html index.htm index.nginx-debian.html;

    server_name example.com;

    location / {
        # First attempt to serve request as file, then
        # as directory, then fall back to displaying a 404.
        try_files $uri $uri/ =404;
    }

    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem; # managed by Certbot
    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot

    if ($scheme != "https") {
        return 301 https://$host$request_uri;
    } # managed by Certbot

}

server {
    listen 80;
    listen [::]:80;

    root /var/www/download;

    index index.html index.htm index.nginx-debian.html;

    server_name download.example.com;

    location / {
        # First attempt to serve request as file, then
        # as directory, then fall back to displaying a 404.
        try_files $uri $uri/ =404;
    }

    #listen 443 ssl; # managed by Certbot
    #ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem; # managed by Certbot
    #ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem; # managed by Certbot
    #include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot

    #if ($scheme != "https") {
    #   return 301 https://$host$request_uri;
    #} # managed by Certbot

}

我可以访问example.com，但我无法访问subdomain.example.com。

向您的 DNS 区域添加 A 记录或 CNAME download.example.com。当然，仅在 nginx 中定义 vhost 不足以让客户端找到它。
