i would like to make a web site, where user put some info, i get this info, send to my program which make somethnig, and then sends the result back to the web site. To do its work, program needs to be run all the time, because it needs some data which has to be generated at start - i need the best performance. Anyway, i wrote a daemon which creates a unix domain socket, and acts like a multithreaded server listening on that socket. In php i wrote a client, which communicate with the daemon. Everything works fine, but the socked has read, write and exec permissions for anybody. Is there a way to start up a daemon, which will create a unix domain socket with permission to read and write for him and apache group only? I have no idea how to manage that. I can't use chown because, only root can do that. Maybe there is a way, to create a user whose group would be apache, and that user will run the daemon. But i want the daemon to be started by init, so how another user can run it??
Thanks in advance for any help.
P.S. Sorry, for my bad english. I hope it at least seems clear ;-] Ask, if i complicated it too much.
