supervisord要求管理的进程，必须是非守护进程(Nondaemonizing)

如果是用workerman写的程序，启动命令是 php server.php start， 不能加 -d 选项

Nondaemonizing of Subprocesses
Programs meant to be run under supervisor should not daemonize themselves. Instead, they should run in the foreground. They should not detach from the terminal from which they are started.
