Как выйти от uwsgi серверного процесса

Я пытаюсь настроить uWSGI для django использование http://adambard.com/blog/start-to-finish-serving-mysql-backed-django-w/ и учебного руководства по http://uwsgi-docs.readthedocs.org/en/latest/tutorials/Django_and_nginx.html. После направлений я имею:

(env1)ubuntu@ip-172-31-28-196:~$ ls
host_type.py  requirements.txt  test.py  tproxy
(env1)ubuntu@ip-172-31-28-196:~$ sudo chmod 666 test.py
(env1)ubuntu@ip-172-31-28-196:~$ uwsgi --http :8000 --wsgi-file test.py

*** WARNING: you are running uWSGI without its master process manager ***
your processes number limit is 7862

probably another instance of uWSGI is running on the same address (:8000).

Как Вы видите, существует другой экземпляр выполнения uWSGI. Как я останавливаю его?
