uwsgi options --wsgi-file and --module not recognized

Question

I am trying to run a Django app using uwsgi. Most instructions I have found refer to a "--wsgi-file" and "--module" to specify the application, but "uwsgi" makes no mention of these options, and when I try and use them:

uwsgi -s /tmp/uwsgi.sock --master --module myapp.wsgi uwsgi: unrecognized option '--module' getopt_long() error 

And

uwsgi -s /tmp/uwsgi.sock --master --wsgi-file myapp/wsgi.py uwsgi: unrecognized option '--wsgi-file' getopt_long() error 

When I run it without either, I get:

uwsgi -s /tmp/uwsgi.sock --master  *** Starting uWSGI 2.0.9 (64bit) on [Fri Jul 10 11:12:04 2015] *** compiled with version: 4.4.7 20120313 (Red Hat 4.4.7-11) on 23 April 2015 19:31:15 os: Linux-2.6.32-504.16.2.el6.x86_64 #1 SMP Tue Mar 10 17:01:00 EDT 2015 machine: x86_64 clock source: unix pcre jit disabled detected number of CPU cores: 2 detected binary path: /usr/sbin/uwsgi your processes number limit is 1024 your memory page size is 4096 bytes detected max file descriptor number: 1024 lock engine: pthread robust mutexes thunder lock: disabled (you can enable it with --thunder-lock) uwsgi socket 0 bound to UNIX address /tmp/uwsgi.sock fd 5 your server socket listen backlog is limited to 100 connections your mercy for graceful operations on workers is 60 seconds mapped 145536 bytes (142 KB) for 1 cores *** Operational MODE: single process *** *** no app loaded. going in full dynamic mode *** *** uWSGI is running in multiple interpreter mode *** spawned uWSGI master process (pid: 26597) spawned uWSGI worker 1 (pid: 26598, cores: 1) 

Why aren't these options recognized? How am I supposed to specify the app to load? What kind of garbage software is this? Should I go back to using Gunicorn?

Answer 1

This means that the python plugin for uWSGI isn't installed or loaded. To verify run:

$ uwsgi --plugins-list 

In general if you have build-essential python-dev etc., you can install via:

$ pip install uwsgi 

On Debian or Ubuntu you can also install it via:

$ apt-get install uwsgi-plugin-python 

On Linux Alpine you currently have to specify where it is:

$ apk add --update uwsgi-python $ uwsgi --plugins-dir /usr/lib/uwsgi/ --need-plugin python --plugins-list *** uWSGI loaded generic plugins ***  *** uWSGI loaded request plugins *** 0: python ... 

Alternatively you can specify its full path via:

$ uwsgi --plugin /usr/lib/uwsgi/python_plugin.so --plugins-list 

Answer 2

Depending how you installed uwsgi also might also need to install the python plugin. e.g.

apt-get install uwsgi-plugin-python
