将子域重定向到 nginx web 服务器时出现问题

Question

Problem explanation

I want to show one service in my domain and another different service in my subdomain, so I purchased a domain and tried to link it to my Nginx web server.

I have buyed the domain in google domains. And uploaded my web application to a Nginx web server.

When I run my domain for example www.balls.com it's redirected perfectly, but when I try to redirect to my subdomain, there is no way to make it work, I have tried different configurations and received 2 different errors:

-DNS doesn't exist (Checked with DNScheck).
-Google DNS page error.

google domain service config:

Nameservers:

-Using the Google Domains nameservers.

DNSSEC

-Your domain has DNSSEC enabled.

Registered hosts

red.balls.com-->111.11.11.11 (My server Address).

Synthetic records

Domain forward
balls.com, www.balls.com → 111.11.11.11 (My server Address).

Custom resource records (Extracted from exported records)

balls.com.balls.com. 3600 IN A 111.11.11.11
red.balls.com.balls.com. 3600 IN A 111.11.11.11
www.balls.com . 3600 IN A 111.11.11.11
www.balls.com.balls.com . 3600 IN A 111.11.11.11

nginx services config:

Subdomain service:

server {
        listen   80;

        root /var/www/redballs.com;

        index index.html index.htm;

        server_name red.balls.com;
}

Subdomain service:

server {

    listen   80;

    root /var/www/balls.com;

    index index.html index.htm;

    server_name balls.com;
}

Thanks for your read time, a simple comment pointing what I'm doing wrong will be very appreciated, as I have finished my application but I'm unable to set up this subdomain. Thanks again.

Answer 1

that sounds a lot like a DNS problem to me. Did you add a DNS record for the subdomain?

Each hostname you want to use needs a mapping in DNS to the IP addresses of the host or a CNAME pointing to another name.

It is a bit hard to debug a DNS Problem without seeing thr actual data.

Sidenote: www.balls.com.balls.com . looks to me like you forgot a dot when creating that entry. In DNS a name always ends with a dot in the configuration (or zone file) if you omit it, the domain name is usually automatically appended.
