Bundle nginx (FE) + apache (BE) for multiple domains?

Question

Nginx

There was a following problem.
There are two domains. One of which is used with subdomains.
example:
First domain: domain1.ru with subdomains sub.domen1.ru, sub2.domain.ru
Second domain: domain2.ru
So, for the first domain and its subdomains, all traffic is proxied and everything works as it should. However, for the second domain, nginx refuses to process any directives and throws out the default site.
vhost from apache will not spread, it makes no sense, it does not come to it.
The nginx config is the following:

worker_processes  1;


events {
    worker_connections  1024;
}


http {
    include       mime.types;
    default_type  application/octet-stream;
  server_names_hash_bucket_size 512;

    sendfile        on;

    keepalive_timeout  0;
      
  server { 
    listen 80 default; 
    server_name _; 
    access_log off; 
    error_log off; 
    return 444; 
  }
   
    server {
        listen	80;
        server_name	domain1.ru www.domain1.ru;

Thank you in advance!

Answer 1

For www.domain2.ru domain2.ru; specify proxypass 127.0.0.1:9998 and apache port 9998

Answer 2

Thank you! In general, it helped, but apache does not respond on port 9998.
apache config:

<VirtualHost *:9998>
    ServerAdmin [email protected]
    DocumentRoot "C:/WEB/Apache24/htdocs/domain2.ru"
    ServerName domain2.ru
    ErrorLog "logs/domain2.ru-error.log"
    CustomLog "logs/domain2.ru-access.log" common
</VirtualHost>

Still, I wonder why subdomains on one port worked successfully, but such a problem arose with another domain. + it looks like a crutch, since you will have to select a separate port for each new site.
Apache solved the problem with the response by adding an additional directive
Listen 9999
Listen 9998
I don’t understand why it doesn’t listen to the specified ports through vhost, but apparently this is the logic of work.
Still, I do not like this method with the allocation of ports. Something is wrong here.
