Configuring Unicorn+nginx to Run Multiple Applications

I am publishing a site created by sinatra on unicorn+nginx, and I would like to add another site, but I don't know how to do it, so please let me know.

Currently, it is as follows.(Excerpts only relevant parts)

Unicorn Configuration

listen "/tmp/unicorn_server.sock", backlog:1024

Configuring nginx

#unicorn
upstream unicorn_server{
  server unix: /tmp/unicorn_server.sock;
}


# Site A
server{

  listen80;
  server_name site-a.com;
  root/var/www/site-a/public;

  location / {
    proxy_pass http://unicorn_server;
  }

}

I would like to add site B to this, but I have no idea what to do.

Should I launch another unicorn, create a new listen, and add it to nginx like site A?
Or do we have multiple listeners in one unicorn?

I wonder if unicorn can be launched multiple times in the first place...
It's my first time and I don't understand many things.

I would appreciate it if you could give me a reference site or a specific example of the configuration.

Please let me know if you need any more information.

Thank you for your cooperation.

Unicorn for Site B must be launched separately.At this time, you must specify a different sock file than Site A in the configuration file.
(The example below specifies /tmp/unicorn_server_b.sock.)

listen "/tmp/unicorn_server_b.sock", backlog:1024

You also need to change the nginx configuration.Add the configuration for site B to the configuration file.
(Assuming Site A has a domain of site-a.com and Site B has a domain of site-b.com)

#Configuring for Site A
upstream unicorn_server{
  server unix: /tmp/unicorn_server.sock;
}

server{

  listen80;
  server_name site-a.com;
  root/var/www/site-a/public;

  location / {
    proxy_pass http://unicorn_server;
  }

}

# Configuration for Site B
upstream unicorn_server_b{
  server unix: /tmp/unicorn_server_b.sock;
}

server{

  listen80;
  server_name site-b.com;
  root/var/www/site-b/public;

  location / {
    proxy_pass http://unicorn_server_b;
  }

}
