我们再来看看用自定义配置文件

.. code-block:: python

  #import multiprocessing

  bind = "127.0.0.1:8000"
  #workers = multiprocessing.cpu_count() * 2 + 1

  worker_class = "sync"
  #worker_class = "gevent_pywsgi"
  #worker_class = "egg:gunicorn#tornado"
  #worker_class = "gunicorn.workers.ggevent.GeventWorker"

  worker_connections = 100

  timeout = 50

  loglevel = 'debug'

  proc_name = 'justforfun'

  def post_fork(server, worker):
      #server.log.info("Worker spawned (pid: %s)", worker.pid)
      pass

  def pre_fork(server, worker):
      #server.log.info("Pre fork ...")
      pass

执行很简单::
 
  gunicorn -c myconf.py myapp:app

输出结果::

  (mypy)hzg@gofast:~/work/rdgunicorn/sample$ gunicorn -c myconf.py myapp:app

看到其中的ttin, ttou，就是用来增加和中止worker进程，怎么做呢？::

  $ kill -TTIN 2139
  $ kill -TTOU 2139
