Why my project uwsgi.ini is throwing Internal Server Error? - django

I am configuring a Django Nginx Server. Up to this stage: uwsgi --socket ProjetAgricole.sock --module ProjetAgricole.wsgi --chmod-socket=666 everything is working fine. However, after configuring the .ini file, and run the uwsgi --ini ProjetAgricole_uwsgi.ini file,I am getting this ouput [uWSGI] getting INI configuration from ProjetAgricole_uwsgi.ini. But when I open the app from the browser I am getting Internal Server Error
Here is my .ini file:
[uwsgi]
# Django-related settings
# the base directory (full path)
chdir = /home/dnsae/my_project/ProjetAgricole/
# Django's wsgi file
module = ProjetAgricole.wsgi
# the virtualenv (full path)
home = /home/dnsae/my_project/my_venv
# process-related settings
# master
master = true
# maximum number of worker processes
processes = 10
# the socket (use the full path to be safe
socket = /home/dnsae/my_project/ProjetAgricole/ProjetAgricole.sock
# ... with appropriate permissions - may be needed
chmod-socket = 666
# clear environment on exit
vacuum = true
# daemonize uwsgi and write message into given log
daemonize = /home/dnsae/my_project/uwsgi-emperor.log
I restarted the server but still I am getting the same error.
Please assist me.

Logging in Django does not work when using uWSGI

I have a problem logging into a file using python built-in module.
Here is an example of how logs are generated:
logging.info('a log message')
Logging works fine when running the app directly through Python. However when running the app through uWSGI, logging does not work.
Here is my uWSGI configuration:
[uwsgi]
module = myapp.app:application
master = true
processes = 5
uid = nginx
socket = /run/uwsgi/myapp.sock
chown-socket = nginx:nginx
chmod-socket = 660
vacuum = true
die-on-term = true
logto = /var/log/myapp/myapp.log
logfile-chown = nginx:nginx
logfile-chmod = 640
EDIT:
The path /var/log/myapp/myapp.log is logging nginx access logs. There is another path configured in a settings.py file. The 2nd path is where application logs are ment to go. But there are non when using uWSGI.
Thanks in advance

(internal error) Ngnix + uwsgi +django : no module named django

So im trying to deploy a django app with nginx and uwsgi , ngnix is running well and the django app is working well with manage.py runserver , but when i try to deploy it with uwsgi it said Internal Server Error , and when i check my uwsgi logs that what i get (No module named django)
the virtualenv python version is 3.6.9 ,i'dont know if this error is caused because of imcompatibilty with python version of virtual environement and the Uwsgi one or just because i missed somethings , my uwsgi specs are
this is my uwsgi ini file :
[uwsgi]
vhost = true
plugins = python
socket = /tmp/mainsock
master = true
enable-threads = true
processes = 4
wsgi-file = /var/www/PTapp-launch/ptapp/wsgi.py
virtualenv = /var/www/venv/site
chdir = /var/www/PTapp-launch
touch-reload = /var/www/PTapp-launch/reload
env = DJANGO_ENV=production
env = DATABASE_NAME=personal_trainer
env = DATABASE_USER=postgres
env = DATABASE_PASSWORD=********
env = DATABASE_HOST=localhost
env = DATABASE_PORT=5432
env = ALLOWED_HOSTS=141.***.***.***
i have finally found the problem , when i was running manage.py runserver i had to use sudo , but when i didnt it was throwing the same error , (no module named Django) , so what i did its i uninstall all requirements and then use super user to create new virtual environnement and link it in uwsgi.ini, i also restart both of nginx and uwsgi, so everything work fine now ...

Serving NGINX with DJANGO on Ubuntu

I am trying to Run my django(1.8) project on Nginx server since it is much faster. I am able to run by using uwsgi --ini commands to setup socket. so what I wants to do is by running NGINX alone want to run my django project, Is there any way to do that? Well the socket created by uwsgi is removing automatically when uwsgi --ini command ends.
NGINX config and .ini ia as shown below :
# mysite_nginx.conf
# the upstream component nginx needs to connect to
upstream django {
server unix:///var/www/html/vir/crum/crumbs.sock;
}
# configuration of the server
server {
# the port your site will be served on
listen 8000;
# the domain name it will serve for
server_name .localhost.com;
charset utf-8;
# max upload size
client_max_body_size 75M; # adjust to taste
# Django media
location /media {
alias /var/www/html/alteryx_vir/crum/media;
}
location /static {
alias /var/www/html/vir/crum/static;
}
# Finally, send all non-media requests to the Django server.
location / {
uwsgi_pass django;
/var/www/html/vir/crum/uwsgi_params;
}
}
>>> uwsgi.ini file :
# mysite_uwsgi.ini file
[uwsgi]
# Django-related settings
# the base directory (full path)
chdir = /var/www/html/vir/crumb/
# Django's wsgi file
module = crum.wsgi
# the virtualenv (/alteryx_vir/)
home = /var/www/html/alteryx_vir/
# process-related settings
# master
master = true
# maximum number of worker processes
processes = 10
# the socket (use the full path to be safe
socket =
/var/www/html/alteryx_vir/crum/crum.sock
#socket = var/run/uwsgi/crum.sock
# ... with appropriate permissions - may be needed
chmod-socket = 666
# clear environment on exit
vacuum = true
Thanks in advance for you help.
What you're asking doesn't make sense. The socket is for communication between nginx and uWSGI. If uWSGI is not running, there would be nothing on the other end of the socket and nothing serving your app.
You need both nginx and uWSGI.
Yes Atlast i could automate everything byusing UWSGI EMPEROR mode.
Now All commands can be automate all you needs to do is to start NGINX server.
Emperror Mode:
Edit /etc/rc.local and add:
/usr/local/bin/uwsgi --emperor /etc/uwsgi/vassals --uid www-data --gid www-data --daemonize /var/log/uwsgi-emperor.log

django-celery as a daemon: not working

I have a website project written with django, celery and rabbitmq. And a '.delay' task (the task creates a new folder) is called when a button is clicked.
Everything works fine with celery (the .delay task is called, and a new folder is created) when I run celery with manage.py like:
python manage.py celeryd
However, when I ran celery as the daemon, even there was no error, the task was not executed (no folder was created).
I was kind of following the tutorial: http://www.arruda.blog.br/programacao/django-celery-in-daemon/
My settings are:
/etc/default/celeryd
:
# Name of nodes to start, here we have a single node
CELERYD_NODES="w1"
# Where to chdir at start.
CELERYD_CHDIR="/var/www/myproject"
# How to call "manage.py celeryd_multi"
CELERYD_MULTI="$CELERYD_CHDIR/manage.py celeryd_multi"
# How to call "manage.py celeryctl"
CELERYCTL="$CELERYD_CHDIR/manage.py celeryctl"
# Extra arguments to celeryd
CELERYD_OPTS=""
# Name of the celery config module.
CELERY_CONFIG_MODULE="myproject.settings"
# %n will be replaced with the nodename.
CELERYD_LOG_FILE="/var/log/celery/w1.log"
CELERYD_PID_FILE="/var/run/celery/w1.pid"
# Workers should run as an unprivileged user.
#CELERYD_USER="root"
#CELERYD_GROUP="root"
# Name of the projects settings module.
export DJANGO_SETTINGS_MODULE="myproject.settings"
the correlated folders are created too
for the '/etc/default/celeryd/init.d' file, I used this version:
https://raw.github.com/ask/celery/1da3aa43d1e6de525beeda398d0acb8841d5b4d2/contrib/generic-init.d/celeryd
for /var/www/myproject/myproject/settings.py, I have:
:
import djcelery
djcelery.setup_loader()
BROKER_HOST = "127.0.0.1"
BROKER_PORT = 5672
BROKER_VHOST = "/"
BROKER_USER = "guest"
BROKER_PASSWORD = "guest"
INSTALLED_APPS = (
'djcelery',
...
)
There was no error when I start celery by using:
/etc/init.d/celeryd start
and no results neither. Does someone know how to fix the problem?
Celery's docs have a daemon troubleshooting section that might be helpful. Celery has a flag that lets you run your init script without actually daemonizing, and that should show what's going wrong:
C_FAKEFORK=1 sh -x /etc/init.d/celeryd start
Newer versions of that init script have a dryrun command that's an easier-to-remember way to run the start command without daemonizing.

uwsgi: no app loaded. going in full dynamic mode

In my uwsgi config, I have these options:
[uwsgi]
chmod-socket = 777
socket = 127.0.0.1:9031
plugins = python
pythonpath = /adminserver/
callable = app
master = True
processes = 4
reload-mercy = 8
cpu-affinity = 1
max-requests = 2000
limit-as = 512
reload-on-as = 256
reload-on-rss = 192
no-orphans
vacuum
My app structure looks like this:
/adminserver
app.py
...
My app.py has these bits of code:
app = Flask(__name__)
...
if __name__ == '__main__':
app.run(host='0.0.0.0', port=5003, debug=True)
The result is that when I try to curl my server, I get this error:
Wed Sep 11 23:28:56 2013 - added /adminserver/ to pythonpath.
Wed Sep 11 23:28:56 2013 - *** no app loaded. going in full dynamic mode ***
Wed Sep 11 23:28:56 2013 - *** uWSGI is running in multiple interpreter mode ***
What do the module and callable options do? The docs say:
module, wsgi Argument: string
Load a WSGI module as the application. The module (sans .py) must be
importable, ie. be in PYTHONPATH.
This option may be set with -w from the command line.
callable Argument: string Default: application
Set default WSGI callable name.
Module
A module in Python maps to a file on disk - when you have a directory like this:
/some-dir
module1.py
module2.py
If you start up a python interpreter while the current working directory is /some-dir you will be able to import each of the modules:
some-dir$ python
>>> import module1, module2
# Module1 and Module2 are now imported
Python searches sys.path (and a few other things, see the docs on import for more information) for a file that matches the name you are trying to import. uwsgi uses Python's import process under the covers to load the module that contains your WSGI application.
Callable
The WSGI PEPs (333 and 3333) specify that a WSGI application is a callable that takes two arguments and returns an iterable that yields bytestrings:
# simple_wsgi.py
# The simplest WSGI application
HELLO_WORLD = b"Hello world!\n"
def simple_app(environ, start_response):
"""Simplest possible application object"""
status = '200 OK'
response_headers = [('Content-type', 'text/plain')]
start_response(status, response_headers)
return [HELLO_WORLD]
uwsgi needs to know the name of a symbol inside of your module that maps to the WSGI application callable, so it can pass in the environment and the start_response callable - essentially, it needs to be able to do the following:
wsgi_app = getattr(simple_wsgi, 'simple_app')
TL;PC (Too Long; Prefer Code)
A simple parallel of what uwsgi is doing:
# Use `module` to know *what* to import
import simple_wsgi
# construct request environment from user input
# create a callable to pass for start_response
# and then ...
# use `callable` to know what to call
wsgi_app = getattr(simple_wsgi, 'simple_app')
# and then call it to respond to the user
response = wsgi_app(environ, start_response)
For anyone else having this problem, if you are sure your configuration is correct, you should check your uWSGI version.
Ubuntu 12.04 LTS provides 1.0.3. Removing that and using pip to install 2.0.4 resolved my issues.
First, check your configuration whether is correct.
my uwsgi.ini configuration:
[uwsgi]
chdir=/home/air/repo/Qiy
uid=nobody
gid=nobody
module=Qiy.wsgi:application
socket=/home/air/repo/Qiy/uwsgi.sock
master=true
workers=5
pidfile=/home/air/repo/Qiy/uwsgi.pid
vacuum=true
thunder-lock=true
enable-threads=true
harakiri=30
post-buffering=4096
daemonize=/home/air/repo/Qiy/uwsgi.log
then use uwsgi --ini uwsgi.ini to run uwsgi.
if not work, you rm -rf the venv directory, and re-initial the venv, and re-try my step.
I re-initial the venv solved my issue, seems the problem is when I pip3 install some packages of requirements.txt, and upgrade the pip, then install uwsgi package. so, I delete the venv, and re-initial my virtual environment.
