There is a site on the Jam.Python web framework , when it starts it takes the address 0.0.0.0 on port 8080 . There is also an Apache
web server with a PHP7 site available at 127.0.0.1 on port 80 . In the /etc/hosts file, I added the address with the application port:

127.0.0.1	  localhost
0.0.0.0:8080	crm.localhost

When running a Python application, it prints out the IP and port:

[email protected]:/var/www/crm$ python server.py 
 * Running on http://0.0.0.0:8080/ (Press CTRL+C to quit)

But that didn't work, going to crm.localhost opens the directory /var/www/html/ which should only be accessible to localhost . Why doesn't it work, and how can I assign a subdomain to a separate port?

I solved everything many times easier, without installing anything extra, I posted the following code on a subdomain:

<!DOCTYPE html><html><head>
  <meta charset="utf-8">
  <title>TITLE</title>
  <style type="text/css">
    * {
        margin: 0;
        padding: 0;
        width: 100%;
        height: 100%;
        border: none;
    }
  </style>
</head><body>
  <iframe src="<?php print($_SERVER['REQUEST_SCHEME'].'://'.$_SERVER['HTTP_HOST'].':8080'.$_SERVER['REQUEST_URI']) ?>"></iframe>
</body></html>

Understand first what 0.0.0.0 is and how /etc/hosts works before adding nonsense there.

you're doing nonsense. Leave hosts alone, take nginx, apache with PHP set to 8081 and configure the rest in nginx

1. On the second line, you entered fundamentally incorrect information into /etc/hosts.
There can be no ports and 0.0.0.0 to create DNS records also does not need to be done - use either 127.0.0.1 if you need access via localhost, or the ip address of the external interface if you need access over the network.
2. Create a separate VirtualHost in apache for your domain, or use default virtualhost if there is one site.
3. Everyone on the network who will access your domain - you also need to make entries in the local hosts file.

Make /etc/hosts:

127.0.0.1 localhost
127.0.0.1 crm.localhost

and open crm.localhost:8080
PS True localhost:8080 will also work the same (and any other IP address registered on this server), because 0.0.0.0 means "use any available IP addresses".
