In most cases, you can only have ONE process binding to ONE IP-address/port combination. Children of this process will then inherit the socket, which is the way how apache works.
On Linux and BSD, there is the SO_REUSEPORT option that can be set by a listening process, so that other processes can also bind to the socket, and let the OS handle which incoming data ends up where.
If you think about that, it opens the port up for hijacking, as the initial listener process has no idea which other processes might also bind to the port and intercept traffic.
So the apache method of one master process binding to the port and spawning children is the prudent one.

Betreff: Re: Run apache without master [wd-vc]
Hi
I want to create different processes not forking from parent or anywhere.
It is still okay if parent process is started and parent process will not fork child processes but parent should serve requests.

Not really. Why not just ignore the parent process? The worst thing
that can happen is that it doesn't manage the children, which you're
already losing in this hypothetical setup.
