NetBox 2.0.4 Install Problems

[Reed Waller]

Good evening everyone,

Apologies if this is the wrong place to post this, but I'm attempting to evaluate NetBox for use within my organization. I've had a hell of a time with the install instructions listed at http://netbox.readthedocs.io/en/stable/installation/netbox/#test-the-application, there were quite a few missing Python dependencies in Ubuntu 14.04. I finally got everything compiled and happy, and have hit a road block when trying to "Test the Application." I see the following output in PuTTY:

username@hostname:/opt/netbox/netbox$ sudo ./manage.py runserver 0.0.0.0:8000 --insecure
[sudo] password for username:
Performing system checks...

System check identified no issues (0 silenced).
May 31, 2017 - 01:47:05
Django version 1.11.1, using settings 'netbox.settings'
Starting development server at http://0.0.0.0:8000/
Quit the server with CONTROL-C.

I've obviously replaced the username/hostname with generic values. When attempting to connect to the IP via http://IP, I get the standard "This page can't be displayed" error in Internet Explorer. Is this because my NetBox server doesn't have X installed, and this test is meant to only be performed locally from the server in question? I'm attempting to contact the server from my workstation, which is on a different subnet. I want to move on to configuring Nginx/Apache, but the instructions clearly state to stop if the page doesn't load:

"Warning

If the test service does not run, or you cannot reach the NetBox home page, something has gone wrong. Do not proceed with the rest of this guide until the installation has been corrected."

The most problematic section of the instructions involved running "sudo pip3 install -r requirements.txt." I had to repeatedly try this command, and each attempt I had to peruse the output and install <insert missing Python package here>. I was quite excited when it installed with no errors, and admittedly didn't expect to run into this issue. This is proving very tedious/challenging, I'm hoping to get my company away from using spreadsheets.

Much thanks,

Snipe,

Check your configuration.py file and make sure you are connecting to the value in ALLOWED_HOSTS.

The development server runs on port 8000 by default, so you need to connect to http://<ip>:8000/

I added the port and now it says "Bad Request (400)." I also received 4 emails from the system with a subject of "[NetBox] ERROR (EXTERNAL IP): Invalid HTTP_HOST header: 'xxx.xxx.xxx.xxx:8000'. You may need to add 'xxx.xxx.xxx.xxx' to ALLOWED_HOSTS." I just checked and had a typo in the ALLOWED_HOSTS area...I must have been half asleep at EOD yesterday =(. Thanks everyone for your help, looking forward to getting this running!

And I sadly spoke too soon, I've immediately hit another roadblock attempting to install nginx, it failed spectacularly so I installed Apache2. I then hit the same stumbling block attempting to install gunicorn and supervisor, and I'm afraid I don't even know where to begin troubleshooting this. Here's the log:

It seems like ConfigParser.py is the cause of this, but I'm not sure how to proceed. Any help is greatly appreciated, I've been out of the Linux world for a few years and am quite rusty =(.

Beginning to wonder if I should have tried to go the Python2 route instead of Python3, starting over because of a hunch sounds less than enjoyable though =/. The good news is I do have a snapshot of the OS in a fresh install state at the very least. Going to temporarily shelve this project until next steps are figured out.

Nginx successfully installed after I went back and used Python2 rather than Python3. I appreciate all of the help!
