Best way to config gunicorn and nginx with django? - django

Question

I am trying to deploy django with gunicorn and nginx on heroku, and i'm kinda confused with the way to config gunicorn and nginx, when i searched through internet, they usually create gunicorn.socket
[Unit]
Description=gunicorn socket
[Socket]
ListenStream=/run/gunicorn.sock
[Install]
WantedBy=sockets.target
and gunicorn.service
[Unit]
Description=gunicorn daemon
Requires=gunicorn.socket
After=network.target
[Service]
User=sammy
Group=www-data
WorkingDirectory=/home/sammy/myprojectdir
ExecStart=/home/sammy/myprojectdir/myprojectenv/bin/gunicorn \
--access-logfile - \
--workers 3 \
--bind unix:/run/gunicorn.sock \
myproject.wsgi:application
[Install]
WantedBy=multi-user.target
but when i go to gunicorn docs : https://docs.gunicorn.org/en/stable/deploy.html. nginx has a config file like this
worker_processes 1;
user nobody nogroup;
# 'user nobody nobody;' for systems with 'nobody' as a group instead
error_log /var/log/nginx/error.log warn;
pid /var/run/nginx.pid;
events {
worker_connections 1024; # increase if you have lots of clients
accept_mutex off; # set to 'on' if nginx worker_processes > 1
# 'use epoll;' to enable for Linux 2.6+
# 'use kqueue;' to enable for FreeBSD, OSX
}
http {
include mime.types;
# fallback in case we can't determine a type
default_type application/octet-stream;
access_log /var/log/nginx/access.log combined;
sendfile on;
upstream app_server {
# fail_timeout=0 means we always retry an upstream even if it failed
# to return a good HTTP response
# for UNIX domain socket setups
server unix:/tmp/gunicorn.sock fail_timeout=0;
# for a TCP configuration
# server 192.168.0.7:8000 fail_timeout=0;
}
server {
# if no Host match, close the connection to prevent host spoofing
listen 80 default_server;
return 444;
}
server {
# use 'listen 80 deferred;' for Linux
# use 'listen 80 accept_filter=httpready;' for FreeBSD
listen 80;
client_max_body_size 4G;
# set the correct host(s) for your site
server_name example.com www.example.com;
keepalive_timeout 5;
# path for static files
root /path/to/app/current/public;
location / {
# checks for static file, if not found proxy to app
try_files $uri #proxy_to_app;
}
location #proxy_to_app {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
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;
proxy_pass http://app_server;
}
error_page 500 502 503 504 /500.html;
location = /500.html {
root /path/to/app/current/public;
}
}
}
So i wonder what the different between these and which is the best way to setup gunicorn, nginx.
Thanks

Answer 1

you can try following steps to deploy django project using nginx, supervisor and gunicron
1- Create new gunicorn script in /myprojectenv/bin/script name e.g gunicorn_start
#!/bin/bash
NAME="myproject"
DJANGODIR=/home/sammy/myprojectdir/myproject
SOCKFILE=/home/sammy/myprojectdir/myproject/run/proj_name.sock
USER=sammy
GROUP=www-data
NUM_WORKERS=3
DJANGO_SETTINGS_MODULE=myproject.settings
DJANGO_WSGI_MODULE=myproject.wsgi
echo "Starting $NAME as whoami"
cd $DJANGODIR
source ../myprojectenv/bin/activate
export DJANGO_SETTINGS_MODULE=$DJANGO_SETTINGS_MODULE
export PYTHONPATH=$DJANGODIR:$PYTHONPATH
RUNDIR=$(dirname $SOCKFILE)
test -d $RUNDIR || mkdir -p $RUNDIR
exec ../myprojectenv/bin/gunicorn ${DJANGO_WSGI_MODULE}:application
--name $NAME
--workers $NUM_WORKERS
--user=$USER --group=$GROUP
--bind=unix:$SOCKFILE
--log-level=debug
--log-file=-
2- Install supervisorctl
pip or yum install supervisor
3- Create conf file under /etc/supervisor.d
Example config file
[program:myproject]
directory=/home/sammy/myprojectdir/myproject
command=/home/sammy/myprojectdir/myprojectenv/bin/gunicorn_start --workers 3 --bind uxix:/home/sammy/myprojectdir/myproject/run/proj_name.sock myproject.wsgi:application
autostart=true
autorestart=true
stderr_logfile=/home/sammy/myprojectdir/myproject/Logs/gunicorn_supervisor.log
stdout_logfile=/home/sammy/myprojectdir/myproject/Logs/gunicorn_supervisor.log
user=sammy
group=www-data
environment=LANG=en_US.UTF-8,LC_ALL=en_US.UTF-8
4- Supervisorctl reread & supervisorctl update
5- nano /etc/nginx/site-available/app.conf
6- ln -s /etc/nginx/sites-available/app.conf /etc/nginx/sites-enabled
7- systemctl restart nginx
Please change folder names and path according to your project.
