Python Question

Uwsgi wont load app when run as service

I have setup a basic flask application in Centos 6, everything is contained in one file( I can run the file with uwsgi from the folder directory with the command

uwsgi --ini myuwsgi.ini
and everything works great. The contents of the ini file are:

http-socket = :9090
plugin = python
wsgi-file = /project/
process = 3
callable = app

However I want to set this up so everytime the server is shutdown or whatever that it will come up on its own. When I try to run the command
service uwsgi start
the logs show that no app was found. The ini file that the service uses is
and I replaced it with my ini file.

The dump of the log is as follows if it helps:

If anyone could tell me why it cant find the app when i specified the location and callable in the ini?

Answer Source

Try the following config and let me know if it works for you:

callable = app
chdir = /path/to/your/project/
http-socket = :9090
plugins = python
processes = 4
virtualenv = /path/to/your/project/venv
wsgi-file = /path/to/your/project/

You may also need to add uid and gid params.

Make sure that you have installed uwsgi-plugin-python package:

apt-get install uwsgi-plugin-python
