Learn how to – How To Install NetBox on Ubuntu 18.04 LTS.

How to Install NetBox on Ubuntu 18.04 LTS is the heading of our article today. NetBox is an open source IPAM / DCIM web application used for managing and documenting computer networks and managing IP addresses. It was Initially conceived by the network engineering team at DigitalOcean.

Netbox encompasses the following aspects of network management:

  • IP address management (IPAM) – IP networks and addresses, VRFs, and VLANs
  • Equipment racks – Organized by group and site
  • Devices – Types of devices and where they are installed
  • Connections – Network, console, and power connections among devices
  • Virtualization – Virtual machines and clusters
  • Data circuits – Long-haul communications circuits and providers
  • Secrets – Encrypted storage of sensitive credentials

Install NetBox on Ubuntu 18.04 LTS

This section will discuss the actual steps you need to follow to have NetBox installed on your Ubuntu 18.04 LTS server. Follow them in order of the appearance, though you can skip a part if you have the software being installed already configiured.

Step 1: Install required dependencies

Start by installing all dependency applications required to run NetBox on Ubuntu 18.04 LTS.

sudo apt-get update
sudo apt-get install -y git gcc nginx redis supervisor python3 python3-dev python3-pip python3-setuptools build-essential libxml2-dev libxslt1-dev libffi-dev graphviz libpq-dev libssl-dev zlib1g-dev

Step 2: Install and configure PostgreSQL database server

NetBox uses PostgreSQL database server to store its data. So install and configure it on Ubuntu 18.04 using our previous guide below:

Then Create a database and user for NetBox.

$ sudo -u postgres psql

CREATE USER netbox WITH PASSWORD 'StrongPassword';

Confirm that you can login to database as netbox user.

# psql -U netbox -h localhost -W
psql (11.1 (Ubuntu 11.1-1.pgdg18.04+1))
SSL connection (protocol: TLSv1.2, cipher: ECDHE-RSA-AES256-GCM-SHA384, bits: 256, compression: off)
Type "help" for help.

Step 3: Install and configure Netbox

Change to /opt/ directory

cd /opt/
sudo git clone -b master https://github.com/digitalocean/netbox.git

Create a configuration file

cd netbox/netbox/netbox/
sudo cp configuration.example.py configuration.py

Edit the configuration file and set allowed host and database login details

# Example: ALLOWED_HOSTS = ['netbox.example.com', 'netbox.internal.local']
ALLOWED_HOSTS = ['localhost']

# PostgreSQL database configuration.
    'NAME': 'netbox',                           # Database name
    'USER': 'netbox',                           # PostgreSQL username
    'PASSWORD': 'StrongPassword',               # PostgreSQL password
    'HOST': 'localhost',                        # Database server
    'PORT': '',                                 # Database port (leave blank for default)

Generate Django SECRET Key:

cd /opt/netbox/netbox
sudo ./generate_secret_key.py

Then set the key on the file /opt/netbox/netbox/netbox/configuration.py


$ sudo vim  /opt/netbox/netbox/netbox/configuration.py
SECRET_KEY = '30m&hqd@09h2i5hro=^l8wqtjw2$!3j%=f2!zh_sey+13jg%3$'

Install Netbox dependencies

sudo pip3 install -r /opt/netbox/requirements.txt

Migrate database data:

cd /opt/netbox/netbox/
sudo python3 manage.py migrate

Create admin user:

$ sudo python3 manage.py createsuperuser
Username (leave blank to use 'root'): admin
Email address: admin@example.com
Password: <Enter Password>
Password (again): <Re-enter Password>
Superuser created successfully.

Move static files

$ cd /opt/netbox/netbox
$ sudo python3 manage.py collectstatic
280 static files copied to '/opt/netbox/netbox/static'.

Step 4: Install and Configure gunicorn

Install gunicorn using pip3:

$ sudo pip3 install gunicorn
Collecting gunicorn
Downloading https://files.pythonhosted.org/packages/8c/da/b8dd8deb741bff556db53902d4706774c8e1e67265f69528c14c003644e6/gunicorn-19.9.0-py2.py3-none-any.whl (112kB)     100% |████████████████████████████████| 122kB 737kB/s
Installing collected packages: gunicorn
Successfully installed gunicorn-19.9.0

Configure gunicorn for Netbox:

cat <<EOF | sudo tee /opt/netbox/gunicorn_config.py
command = '/usr/local/bin/gunicorn'
pythonpath = '/opt/netbox/netbox'
bind = 'localhost:8085'
workers = 3
user = 'www-data'

Step 5: Configure Supervisord

Create a supervisord configuration file:

cat <<EOF | sudo tee /etc/supervisor/conf.d/netbox.conf
command = gunicorn -c /opt/netbox/gunicorn_config.py netbox.wsgi
directory = /opt/netbox/netbox/
user = www-data

Restart and enable supervisord service to start on boot.

sudo systemctl restart supervisor.service
sudo systemctl enable supervisor.service

Status should show running with netbox output.

$ systemctl status  supervisor

Step 6: Configure Nginx Web Server

Let’s configure Nginx web server to help us access Netbox via Domain name rather than specifying an IP address and a port.

Create new Nginx configuration file for Netbox.

sudo vim /etc/nginx/conf.d/netbox.conf

With below data.

server {
    listen 80;
    server_name netbox.example.com;
    client_max_body_size 25m;

    location /static/ {
        alias /opt/netbox/netbox/static/;

    location / {
        proxy_pass http://localhost:8085;

Check Nginx configuration syntax and restart its service

$ sudo  nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

If OK, restart Nginx service

sudo systemctl restart nginx

Step 7: Access Netbox Web UI

Open your default web browser and open Netbox server hostname. To make changes, login with admin user created earlier.

Enjoy using Netbox to document your network infrastructure. Refer to official Netbox documentation for more details.
