gunicorn.py
===========




The gunicorn.py file is created automatically by  :ref:`deploybuilder<installation_guide/deploy/gnrdeploybuilder>`  and is located in the site configuration folder.

A typical file is composed as follows::

  bind = 'unix:/home/ubuntu/gitrepos/genropynet/projects/genropynet/sites/genropynet/sockets/gunicorn.sock'
  pidfile = '/home/ubuntu/gitrepos/genropynet/projects/genropynet/sites/genropynet/genropynet_pid'
  demon = False
  accesslog = '/home/ubuntu/gitrepos/genropynet/projects/genropynet/sites/genropynet/logs/access.log'
  errorlog = '/home/ubuntu/gitrepos/genropynet/projects/genropynet/sites/genropynet/logs/error.log'
  logfile = '/home/ubuntu/gitrepos/genropynet/projects/genropynet/sites/genropynet/logs/main.log'
  workers = 5
  loglevel = 'error'
  chdir = '/home/ubuntu/gitrepos/genropynet/projects/genropynet/sites/genropynet'
  reload = False
  capture_output = True
  worker_class = 'gevent'
  maximum_requests = 300
  max_requests_jitter = 50
  expiry = 1800
  graceful_timeout = 600
  
The parameters we can modify are:

 - **worker**: how many processes we want to use to serve the site
 - **max_requests**: The number of requests served before a process starts automatically
 - **max_requests_jitter**: modifies for each process the value of the previous parameter with a random number between 0 and the set value
