Processes

[The Little Guy]

using shell_exec can I run 2+ of the same process on a linux machine?

 

Currently I have this:

$newPort = newPort();
socket_write($client, 'new_port:'.$newPort."\0");
shell_exec('~/processes/mini '.$newPort.' &');

 

what happens, is that it doesn't work if I already have that process running (I think)...

 

is this fixable?

shell_exec spawns a new process whenever it is called.

using this:

 

shell_exec('~/processes/mini '.$newPort.' &');

 

I think it makes the code hang, because once I connect with one client, I cannot connect with a second on. I I remove that line, I can connect with 2+ clients. I'm I writing that correctly?

[The Little Guy]

anyone?

You think it makes your code hang?

 

What does mini do exactly?

[The Little Guy]

Yes, I know it hangs, because I placed an echo after it and it doesn't echo it out.

 

I found this:

 

shell_exec("nohup ~/processes/mini $newPort > /dev/null & echo $!");

 

after using it, it no longer hung, and I was able to have 2+ instances of mini running.

 

server is the main client when a user connects to it, it then it routes them to "mini" the actual chatting client. mini opens a port, and those on that port can chat with each other.

 

anyway, if that made any sense is that a good way to do it?
