Originally created by @mike-mosher on GitHub (Jun 30, 2016).

I followed the docs and installed everything to the default directories. After installing gunicorn and supervisor, I get '502 Bad Gateway' when I browse to the site.

When looking at 'service gunicorn status', I see:

● gunicorn.service
   Loaded: loaded (/etc/init.d/gunicorn; bad; vendor preset: enabled)
   Active: active (exited) since Wed 2016-06-29 20:41:33 MDT; 11min ago

  Process: 1778 ExecStart=/etc/init.d/gunicorn start (code=exited, status=0/S

Jun 29 20:41:33 host gunicorn[1778]:  *

When I try to run the gunicorn -c /opt/netbox/gunicorn_config.py netbox.wsgi command in the /etc/supervisor/conf.d/netbox.conf config file, from the /opt/netbox/netbox/ directory, I get the following:

if I run as sudo, I get this:

Did you run pip install -r requirements.txt during the installation of Netbox?
This should resolve your missing modules.

I'm going to close this issue. I worked with stretch on irc all night, and he got it working running Ubuntu 16.04 (which is what I'm running, freshly installed). Must be something with my specific server.

supervisor: couldn't chdir to /opt/netbox/netbox/: EACCES
supervisor: child process was not spawned

Earlier the error was probably caused by permission. I set www-data to own /opt/netbox/netbox, but gunicorn is still failing

I am running Debian 8.6 and I had the same permission issue but what I did was a chown www-data:www-data -R /opt/netbox and after that I could start gunicorn manually:

root@netbox:/opt/netbox# sudo gunicorn -c /opt/netbox/gunicorn_config.py netbox.wsgi

[2016-10-04 08:13:21 +0000] [14135] [INFO] Booting worker with pid: 14135

I have another issue though: I try to connect to netbox, locally, using elinks http://127.0.0.1:8001 and I get a 400 eror (Bad request). I thought at first that it has to do with nginx config so I switched to apache. Same error applies.

My guess is that something is wrong with gunicorn but I can't figure it out. If I start nebox manually as in the guide (/manage.py runserver 0.0.0.0:8000 --insecure) it works just fine.

Any help would be appreciated!

I'm still new to Linux, so this may not be your issue, but this helped me:

@Fyzzle commented on GitHub (Oct 5, 2016):

@therealjoshuad I tried that and my error went from a 502 to 400. So progress at least.

Edit: The 400 was an unrelated "ALLOWED_HOSTS" issue. That fix seemed to work for me.

I ran into this issue as well from a fresh Ubuntu 16.04.2 install and using python 3. Gunicorn is trying to run from python2.7

File "/usr/lib/python2.7/dist-packages/gunicorn/util.py", line 366, in import_app
    __import__(module)
  File "/opt/netbox/netbox/netbox/wsgi.py", line 12, in <module>
    from django.core.wsgi import get_wsgi_application

Installing gunicorn (and uwsgi, maybe not required) for python3 fixed the issue for me.
Run:sudo -H pip3 install gunicorn uwsgi

@LociNetworks, I have the same issue. I am using python3.6 on Linux Ubuntu but when I run this command gunicorn --bind 0.0.0.0:8000 myproject.wsgi it looks into Python2.7 directories. I tried the command what you mentioned Run:sudo -H pip3 install gunicorn uwsgi, but its not working for me. Any idea?

@LociNetworks thanks I found the mistake. I install it package at OS level. I remove the package and reinstall while activating the virtual environment I created. Now its fine.

But now I am not able to find the following file at the following path
sudo nano /etc/systemd/system/gunicorn.service

setting up django on Linux I am following the steps from the below location,
