I built an API with flask. My app does not have any static assets hence there's no reason for me to use nginx.
I wish to run gunicorn on port 80.
I have a "deploy script":
mkdir .log 2> /dev/null DEBUG=0 gunicorn -b 0.0.0.0:80 backend:app --access-logfile .log/access.log --error-logfile .log/general.log I wish to run gunicorn on port 80 with authbind. I followed this guide here.
Note that I am able to run authbind python -m SimpleHTTPServer 80
When I try to run authbind ./deployment.run 80,
I am seeing the following error:
2013-04-25 15:32:55 [24006] [ERROR] Can't connect to ('0.0.0.0', 80) 2013-04-25 15:33:08 [24018] [INFO] Starting gunicorn 0.17.4 2013-04-25 15:33:08 [24018] [ERROR] Retrying in 1 second. 2013-04-25 15:33:09 [24018] [ERROR] Retrying in 1 second. 2013-04-25 15:33:10 [24018] [ERROR] Retrying in 1 second. 2013-04-25 15:33:11 [24018] [ERROR] Retrying in 1 second. 2013-04-25 15:33:12 [24018] [ERROR] Retrying in 1 second. Any ideas why I am unable to bind gunicorn to port 80?
Any recommendations?

Configure Gunicorn The Gunicorn process will start and bind to all host IP addresses on port 8081. Use control + z to terminate Gunicorn process. Note: The default (host) port can be configured here to use any other open port on which you prefer to expose the Transform. Note: In this case 'python3' must be specified.
Running sudo -u www-data curl --unix-socket /run/gunicorn. sock http , our Gunicorn service will be automatically started and you should see some HTML from your server in the terminal. systemd employs cgroups to track the processes of a service, so it doesn't need pid files.
It is recommended in Gunicorn docs to run it behind a proxy server. Technically, you don't really need Nginx. BUT it's the Internet: your server will receive plenty of malformed HTTP requests which are made by bots and vulnerability scanner scripts.
You can run Gunicorn by using commands or integrate with popular frameworks like Django, Pyramid, or TurboGears. For deploying Gunicorn in production see Deploying Gunicorn.
If you are on a unix-like environment, ports < 1024 (like 80) will require superuser privileges.
