I spent two days working with Gunicorn and I couldn’t get it working. I followed many tutorials on DigitalOcean and other external resources and now I finally am posting my question with all the settings I worked with for last couple of days.
I am using Gunicorn 18.0.0 along with Supervisor and Nginx. My project structure is /home/umer/myvirtualenv/myproject.
I got my gunicorn upstart script in /home/umer/myvirtualenv/bin/gunicorn_start including following information:
NAME="zik" # Name of the application
DJANGODIR=/home/umer/myvirtualenv/myproject# Django project directory
SOCKFILE=/home/umer/myvirtualenv/myproject/run/gunicorn.sock # we will communicte using this unix socket
USER=umer # the user to run as
GROUP=webapps # the group to run as
NUM_WORKERS=3 # how many worker processes should Gunicorn spawn
DJANGO_SETTINGS_MODULE=myproject.settings # which settings file should Django use
DJANGO_WSGI_MODULE=myproject.wsgi # WSGI module name
echo "Starting $NAME as `whoami`"
# Activate the virtual environment
cd $DJANGODIR
source ../bin/activate
export DJANGO_SETTINGS_MODULE=$DJANGO_SETTINGS_MODULE
export PYTHONPATH=$DJANGODIR:$PYTHONPATH
# Create the run directory if it doesn't exist
RUNDIR=$(dirname $SOCKFILE)
test -d $RUNDIR || mkdir -p $RUNDIR
# Start your Django Unicorn
# Programs meant to be run under supervisor should not daemonize themselves (do not use --daemon)
exec ../bin/gunicorn ${DJANGO_WSGI_MODULE}:application \
--name $NAME \
--workers $NUM_WORKERS \
--user=$USER --group=$GROUP \
--bind=unix:$SOCKFILE \
--log-level=debug \
--log-file=-
For Nginx I have my settings like following:
upstream myproject_server {
# fail_timeout=0 means we always retry an upstream even if it failed
# to return a good HTTP response (in case the Unicorn master nukes a
# single worker for timing out).
server 127.0.0.1:9000 fail_timeout=0;
}
server {
listen 80;
server_name example.com;
client_max_body_size 4G;
access_log /home/umer/myvirtualenv/myproject/logs/nginx-access.log;
error_log /home/umer/myvirtualenv/myproject/logs/nginx-error.log;
location /static/ {
alias /umer/myvirtualenv/myproject/static;
}
location /media/ {
alias /umer/myvirtualenv/myproject/media/;
}
location / {
# an HTTP header important enough to have its own Wikipedia entry:
# http://en.wikipedia.org/wiki/X-Forwarded-For
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
# enable this if and only if you use HTTPS, this helps Rack
# set the proper protocol for doing redirects:
# proxy_set_header X-Forwarded-Proto https;
# pass the Host: header from the client right along so redirects
# can be set properly within the Rack application
proxy_set_header Host $http_host;
# we don't want nginx trying to do something clever with
# redirects, we set the Host: header above already.
proxy_redirect off;
# set "proxy_buffering off" *only* for Rainbows! when doing
# Comet/long-poll stuff. It's also safe to set if you're
# using only serving fast clients with Unicorn + nginx.
# Otherwise you _want_ nginx to buffer responses to slow
# clients, really.
# proxy_buffering off;
# Try to serve static files from nginx, no point in making an
# *application* server like Unicorn/Rainbows! serve static files.
if (!-f $request_filename) {
proxy_pass http://myproject_server;
break;
}
}
# Error pages
error_page 500 502 503 504 /500.html;
location = /500.html {
root /umer/myvirtualenv/myproject/static;
}
}
My Gunicorn config file in /etc/gunicorn.d/gunicorn.py includes following:
"""gunicorn WSGI server configuration."""
from multiprocessing import cpu_count
from os import environ
def max_workers():
return cpu_count() * 2 + 1
max_requests = 1000
worker_class = 'gevent'
workers = max_workers()
I’ve associated my sites-available in sites-enabled. My gunicorn socket is under the directory /home/umer/myvirtualenv/myproject/run/gunicorn.sock
My supervisor configurations in /etc/supervisor/conf.d/myproject.conf are following:
[program:gunicorn]
command = /home/umer/myvirtualenv/bin/gunicorn myproject.wsgi:application --bind example.com:8000 --workers=3 --pid /tmp/gunicorn.pid
; Command to start
user = umer ; User to run as
stdout_logfile = /home/umer/myvirtualenv/logs/gunicorn_supervisor.log ; Where to write log messages
redirect_stderr = true ; Save stderr in the same log
environment=LANG=en_US.UTF-8,LC_ALL=en_US.UTF-8 ; Set UTF-8 as default encoding
Kindly advise so I can get this done.
