Production Setup
|
|
================
|
|
|
|
Although there are many HTTP proxies available, we strongly advise that you use Nginx_. If you choose another proxy server you need to make sure that it buffers slow clients. Without this buffering Gunicorn will be easily susceptible to Denial-Of-Service attacks.
|
|
|
|
Nginx Config
|
|
------------
|
|
|
|
An `example configuration`_ file for use with Nginx_::
|
|
|
|
worker_processes 1;
|
|
|
|
user nobody nogroup;
|
|
pid /tmp/nginx.pid;
|
|
error_log /tmp/nginx.error.log;
|
|
|
|
events {
|
|
worker_connections 1024;
|
|
accept_mutex off;
|
|
}
|
|
|
|
http {
|
|
include mime.types;
|
|
default_type application/octet-stream;
|
|
access_log /tmp/nginx.access.log combined;
|
|
sendfile on;
|
|
|
|
upstream app_server {
|
|
server unix:/tmp/gunicorn.sock fail_timeout=0;
|
|
# For a TCP configuration:
|
|
# server 192.168.0.7:8000 fail_timeout=0;
|
|
}
|
|
|
|
server {
|
|
listen 80 default;
|
|
client_max_body_size 4G;
|
|
server_name _;
|
|
|
|
keepalive_timeout 5;
|
|
|
|
# path for static files
|
|
root /path/to/app/current/public;
|
|
|
|
location / {
|
|
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
|
|
proxy_set_header Host $http_host;
|
|
proxy_redirect off;
|
|
|
|
if (!-f $request_filename) {
|
|
proxy_pass http://app_server;
|
|
break;
|
|
}
|
|
}
|
|
|
|
error_page 500 502 503 504 /500.html;
|
|
location = /500.html {
|
|
root /path/to/app/current/public;
|
|
}
|
|
}
|
|
}

|
Daemon Monitoring
|
|
-----------------
|
|
|
|
A popular method for deploying Gunicorn is to have it monitored by runit_. An `example service`_ definition::
|
|
|
|
#!/bin sh
|
|
|
|
GUNICORN=/usr/local/bin/gunicorn
|
|
ROOT=/path/to/project
|
|
PID=/var/run/gunicorn.pid
|
|
|
|
APP=main:application
|
|
|
|
if [ -f $PID ]; then rm $PID fi
|
|
|
|
cd $ROOT
|
|
exec $GUNICORN -C $ROOT/gunicorn.conf.py --pidfile=$PID $APP
|
|
|
|
Another useful tool to monitor and control Gunicorn is Supervisor_. A
|
|
`simple configuration`_ is::
|
|
|
|
[program:gunicorn]
|
|
command=/usr/local/bin/gunicorn main:application -c /path/to/project/gunicorn.conf.py
|
|
directory=/path/to/project
|
|
user=nobody
|
|
autostart=true
|
|
autorestart=true
|
|
redirect_stderr=True
