I just started to use uWSGI and Django. I want to invoke it manually.
I'm using python36, Django 2 and if I install uWSGI (pip install uwsgi) in venv and everything is ok.
Q1. When using outside of venv I first installed uWSGI:
pip install uwsgi -> 2.0.18 version
Installed plugins: sudo apt-get install python3-setuptools
Trying to run with python36:
uwsgi --plugin-dir=/usr/lib/uwsgi/plugins --plugin python3 --master --http :5000 --home ~/my_playground/webapps/ --chdir ~/my_playground/webapps/p_tscze/ --module p_tscze.wsgi:application
Plugins in /usr/lib/uwsgi/plugins:
/usr/lib/uwsgi/plugins$ ls | grep python3
asyncio_python36_plugin.so
asyncio_python3_plugin.so
python36_plugin.so
python3_plugin.so
Result obtained -> note python 2.7:
!!! UNABLE to load uWSGI plugin: ./python36_plugin.so: undefined symbol: uwsgi_legion_scrolls !!!

So please can you let me know what I'm doing wrong?
Q2. When comparing the result of the admin page (./manage.py runserver) and result obtained using uwsgi frontend is not the same, why?
Thanks in advance

I am trying to serve a Django application with uWSGI from Docker. I am using supervisord to start the process for me at the end of the Dockerfile. When I run the image, it says that the uWSGI process starts and succeeds, but I'm unable to view the application at the URL I thought would display it. Perhaps I do not have things set up/configured correctly?
I am not having supervisord start nginx right now because I am currently serving static files via Amazon S3, and want to first focus on getting the wsgi up and running.
I am successful in running the application using uwsgi locally by doing uwsgi --init uwsgi.ini:local, but I am having trouble moving it into docker.
Here is my Dockerfile
FROM ubuntu:14.04
# Get most recent apt-get
RUN apt-get -y update
# Install python and other tools
RUN apt-get install -y tar git curl nano wget dialog net-tools build-essential

And here is my uwsgi.ini
[uwsgi]

# load the module from wsgi.py, it is a python path from
# the directory above.
module=my_app.wsgi:application
# allow anyone to connect to the socket. This is very permissive
chmod-socket=666
http = :8080
And here is my supervisor-app.conf file
[program:app-uwsgi]
command = /usr/local/bin/uwsgi --ini /home/docker/code/uwsgi.ini
From a MAC using boot2docker, I am trying to access the application at $(boot2docker ip):8080
Ultimately I want to upload this container to AWS Elastic Beanstalk, with not only a uWSGI process running, but a celery worker running as well.
When I run my container, I can see from the logs that both supervisor and uwsgi successfully start. I was able to get things running on my local machine both using uwsgi by itself and uwsgi through supervisor, but for some reason when I containerize the thing I can't find it anywhere.
Here is what is logged when I boot up the docker container
2014-12-25 15:08:03,950 CRIT Supervisor running as root (no user in config file)
2014-12-25 15:08:03,953 INFO supervisord started with pid 1
2014-12-25 15:08:04,957 INFO spawned: 'uwsgi' with pid 9
2014-12-25 15:08:05,970 INFO success: uwsgi entered RUNNING state, process has stayed up for > than 1 seconds (startsecs)
How are you starting the docker container?
I don't see any CMD or ENTRYPOINT script, so I'm unclear as to how anything is getting started.
In general, I would advise avoiding things like supervisord unless absolutely necessary, just start uWSGI in the foreground from a CMD line. Try adding the following as the last line in the Dockerfile:
CMD ["/usr/local/bin/uwsgi", "--ini", "/home/docker/code/uwsgi.ini"]
and then just run with docker run -p 8000:8000 image_name. You should get some reply from uWSGI. If that works, I recommend you move the other services (postgres, node, to separate containers). There are official images for Node, Python and Postgres which should save you some time.
Remember, Docker containers only run as long as their main process (which must be in the foreground).
I am having a an issue where I can't get uwsgi to run on my machine. I keep getting this:
/usr/bin$ sudo service ppuwsgi start
>>ppuwsgi start/running, process 17452
/usr/bin$ sudo service ppuwsgi status
>>ppuwsgi stop/waiting
I think I might be having a similar issue as this guy here. However, I didn't install from source. I saw that the machine came with python3.4. But I did do
sudo apt-get install libpq-dev python3-dev
and maybe even
sudo apt-get install python-dev
I want to think I don't have python installed twice. And I have no idea how to check and see. I opened up my usr/local/bin and saw uwsgi and some pip stuff but no python.
Lastly, here is my /etc/init/ppuwsgi.conf
# file: /etc/init/ppuwsgi.conf
description "uWSGI server for PingPlot"
start on runlevel [2345]
stop on runlevel [!2345]
respawn

The sock file and log file seem to get created as well (the log file is empty). I don't know what the deal is.
Edit:
So I opened up user/bin/ and here are all the python things I have.
EDIT: I LIED
I am getting stuff in the error log. I just couldn't see it because I opened vim without sudo. Here is the error log:

Based on the error log. I changed my version of Python. I uninstalled uwsgi and pip and then reinstalled it using python3 pip.
sudo apt-get install python3-pip
sudo pip install uwsgi
Then I was able to get uwsgi running.
I'm trying to use uwsgi + python2.7 + django + nginx on debian 6.
I installed uwsgi with the command: pip2.7 install uwsgi so it's running with python 2.7.
I'm running uwsgi in emperor mode with the command:
uwsgi --emperor /etc/uwsgi/vassals/ -d /var/log/uwsgi.log --pidfile /var/run/uwsgi.pid
The vassals folder contains only one app for the moment. Here is it's yaml file:
uwsgi:
socket: /home/uwsgi/uwsgi/uwsgi.sock
virtualenv: /opt/myproj/virt
pythonpath: /home/uwsgi/project/my_proj
pidfile: /home/uwsgi/uwsgi/uwsgi.pid
uid: uwsgi
gid: uwsgi
chmod-socket: 1
module: wsgi_app
daemonize: /home/uwsgi/uwsgi/uwsgi.log
harakiri-verbose: 1
This is the content of the Django project file:
#! /usr/bin/python
SITE_DIR = '/home/uwsgi/project/my_proj'
import site
site.addsitedir(SITE_DIR)
import os
import sys
sys.path.append(SITE_DIR)
sys.path.append('/home/uwsgi/project/')
os.environ['DJANGO_SETTINGS_MODULE'] = 'my_proj.settings'
import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()
Now, here is the result in the /home/uwsgi/uwsgi/uwsgi.log file when I try to launch it:

As you can see, uwsgi can't import the site module so uwsgi keeps trying to restart the app.
So I tried to add the no-site :1 option in the yaml file. The result is that I can't import anything in my Django project file...
I also know it's not linked to the project because if I run uwsgi with python 2.6, it just works fine... Unfortunally, I have to run it with python2.7...
Do you have any idea what happens ?
Thanks a lot!
Be sure your virtualenv is built for python2.7, otherwise it cannot be used.
It has to contains /opt/myproj/virt/lib/python2.7 directory
