[uwsgi]
# enable master process manager
master = true

# spawn 2 uWSGI worker processes
workers = 2

# bind to UNIX socket at /run/uwsgi/<confnamespace>/<confname>/socket
socket = /tmp/dapurhemat.sock

# set mode of created UNIX socket
chmod-socket = 666

# place timestamps into log
log-date = true

# user identifier of uWSGI processes
uid = root

# group identifier of uWSGI processes
gid = root

; define variables to use in this script
project = dapurhemat

; number of worker processes
processes = 8

; plugins=python
; project-level logging to the logs/ folder

; django >= 1.4 project
chdir = /var/yodi/dapurhemat
wsgi-file=/var/yodi/dapurhemat/dapurhemat/wsgi.py

virtualenv=/root/.virtualenvs/dapurhemat

; run master process as root
enable-threads = true

vacuum = true
env = DJANGO_SETTINGS_MODULE=kargo.settings
pidfile2 = /tmp/dapurhemat.pid

You can test your app first with “python manage.py runserveR” before integrate with uwsgi

We also can check by manually running the “.ini” configuration:

1
uwsgi --ini yourfile.ini

If you got error like below:

Then, please install :

1
apt-get install uwsgi uwsgi-plugin-python
