Getting Started

This guide documents the process of installing NetBox on an Ubuntu 14.04 server with nginx and gunicorn.

[TOC]

PostgreSQL

Installation

The following packages are needed to install PostgreSQL:

postgresql
libpq-dev
python-psycopg2

# apt-get install postgresql libpq-dev python-psycopg2

Configuration

At a minimum, we need to create a database for NetBox and assign it a username and password for authentication. This is done with the following commands.

DO NOT USE THE PASSWORD FROM THE EXAMPLE.

# sudo -u postgres psql
psql (9.3.13)
Type "help" for help.

postgres=# CREATE DATABASE netbox;
CREATE DATABASE
postgres=# CREATE USER netbox WITH PASSWORD 'J5brHrAXFLQSif0K';
CREATE ROLE
postgres=# GRANT ALL PRIVILEGES ON DATABASE netbox TO netbox;
GRANT
postgres=# \q

You can verify that authentication works using the following command:

# psql -U netbox -h localhost -W

NetBox

Installation

NetBox requires following dependencies:

python2.7
python-dev
python-pip
libxml2-dev
libxslt1-dev
libffi-dev
graphviz*

# apt-get install python2.7 python-dev git python-pip libxml2-dev libxslt1-dev libffi-dev graphviz

*graphviz is needed to render topology maps. If you have no need for this feature, graphviz is not required.

You may opt to install NetBox either from a numbered release or by cloning the master branch of its repository on GitHub.

Option A: Download a Release

Download the latest stable release from GitHub as a tarball or ZIP archive. Extract it to your desired path. In this example, we'll use /opt/netbox.

# wget https://github.com/digitalocean/netbox/archive/vX.Y.Z.tar.gz
# tar -xzf vX.Y.Z.tar.gz -C /opt
# cd /opt/
# ln -s netbox-1.0.4/ netbox
# cd /opt/netbox/

Option B: Clone the Git Repository

Create the base directory for the NetBox installation. For this guide, we'll use /opt/netbox.

# mkdir -p /opt/netbox/
# cd /opt/netbox/

If git is not already installed, install it:

# sudo apt-get install git

Next, clone the NetBox git repository into the current directory:

# git clone https://github.com/digitalocean/netbox.git .

Install Python Packages

Install the necessary Python packages using pip. (If you encounter any compilation errors during this step, ensure that you've installed all of the required dependencies.)

# pip install -r requirements.txt

Configuration

Move into the NetBox configuration directory and make a copy of configuration.example.py named configuration.py.

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

Open configuration.py with your preferred editor and set the following variables:

ALLOWED_HOSTS
DATABASE
SECRET_KEY

ALLOWED_HOSTS

This is a list of the valid hostnames by which this server can be reached. You must specify at least one name or IP address.

Example:

ALLOWED_HOSTS = ['netbox.example.com', '192.0.2.123']

DATABASE

This parameter holds the database configuration details. You must define the username and password used when you configured PostgreSQL. If the service is running on a remote host, replace localhost with its address.

Example:

DATABASE = {
    'NAME': 'netbox',               # Database name
    'USER': 'netbox',               # PostgreSQL username
    'PASSWORD': 'J5brHrAXFLQSif0K', # PostgreSQL password
    'HOST': 'localhost',            # Database server
    'PORT': '',                     # Database port (leave blank for default)
}

SECRET_KEY

Generate a random secret key of at least 50 alphanumeric characters. This key must be unique to this installation and must not be shared outside the local system.

You may use the script located at netbox/generate_secret_key.py to generate a suitable key.

Run Migrations

Before NetBox can run, we need to install the database schema. This is done by running ./manage.py migrate from the netbox directory (/opt/netbox/netbox/ in our example):

# ./manage.py migrate
Operations to perform:
  Apply all migrations: dcim, sessions, admin, ipam, utilities, auth, circuits, contenttypes, extras, secrets, users
Running migrations:
  Rendering model states... DONE
  Applying contenttypes.0001_initial... OK
  Applying auth.0001_initial... OK
  Applying admin.0001_initial... OK
  ...

If this step results in a PostgreSQL authentication error, ensure that the username and password created in the database match what has been specified in configuration.py

Create a Super User

NetBox does not come with any predefined user accounts. You'll need to create a super user to be able to log into NetBox:

# ./manage.py createsuperuser
Username: admin
Email address: admin@example.com
Password: 
Password (again): 
Superuser created successfully.

Collect Static Files

# ./manage.py collectstatic

You have requested to collect static files at the destination
location as specified in your settings:

    /opt/netbox/netbox/static

This will overwrite existing files!
Are you sure you want to do this?

Type 'yes' to continue, or 'no' to cancel: yes

Test the Application

At this point, NetBox should be able to run. We can verify this by starting a development instance:

# ./manage.py runserver 0.0.0.0:8000 --insecure
Performing system checks...

System check identified no issues (0 silenced).
June 17, 2016 - 16:17:36
Django version 1.9.7, using settings 'netbox.settings'
Starting development server at http://0.0.0.0:8000/
Quit the server with CONTROL-C.

Now if we navigate to the name or IP of the server (as defined in ALLOWED_HOSTS) we should be greeted with the NetBox home page. Note that this built-in web service is for development and testing purposes only. It is not suited for production use.

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.

Web Server and gunicorn

Installation

We'll set up a simple HTTP front end using gunicorn for the purposes of this guide. For web servers, we provide example configurations for both nginx and Apache. (You are of course free to use whichever combination of HTTP and WSGI services you'd like.) We'll also use supervisord for service persistence.

# apt-get install gunicorn supervisor

nginx Configuration

The following will serve as a minimal nginx configuration. Be sure to modify your server name and installation path appropriately.

# apt-get install nginx

Once nginx is installed, proceed with the following configuration:

server {
    listen 80;

    server_name netbox.example.com;

    access_log off;

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

    location / {
        proxy_pass http://127.0.0.1:8001;
        proxy_set_header X-Forwarded-Host $server_name;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-Proto $scheme;
        add_header P3P 'CP="ALL DSP COR PSAa PSDa OUR NOR ONL UNI COM NAV"';
    }
}

Save this configuration to /etc/nginx/sites-available/netbox. Then, delete /etc/nginx/sites-enabled/default and create a symlink in the sites-enabled directory to the configuration file you just created.

# cd /etc/nginx/sites-enabled/
# rm default
# ln -s /etc/nginx/sites-available/netbox

Restart the nginx service to use the new configuration.

# service nginx restart
 * Restarting nginx nginx

Apache Configuration

The following configuration should work for Apache. Be sure to modify the ServerName appropriately.

<VirtualHost *:80>
    ProxyPreserveHost On

    ServerName netbox.example.com

    Alias /static /opt/netbox/netbox/static

    <Directory /opt/netbox/netbox/static>
        Options Indexes FollowSymLinks MultiViews
        AllowOverride None
        Require all granted
    </Directory>

    <Location /static>
        ProxyPass !
    </Location>

    ProxyPass / http://127.0.0.1:8001/
    ProxyPassReverse / http://127.0.0.1:8001/
</VirtualHost>

Save the contents of the above example in /etc/apache2/sites-available/netbox.conf, enable the proxy and proxy_http modules, and reload Apache:

# a2enmod proxy
# a2enmod proxy_http
# a2ensite netbox
# service apache2 restart

gunicorn Configuration

Save the following configuration file in the root netbox installation path (in this example, /opt/netbox/.) as gunicorn_config.py. Be sure to verify the location of the gunicorn executable (e.g. which gunicorn) and to update the pythonpath variable if needed.

command = '/usr/bin/gunicorn'
pythonpath = '/opt/netbox/netbox'
bind = '127.0.0.1:8001'
workers = 3
user = 'www-data'

supervisord Configuration

Save the following as /etc/supervisor/conf.d/netbox.conf. Update the command and directory paths as needed.

[program:netbox]
command = gunicorn -c /opt/netbox/gunicorn_config.py netbox.wsgi
directory = /opt/netbox/netbox/
user = www-data

Finally, restart the supervisor service to detect and run the gunicorn service:

# service supervisor restart

At this point, you should be able to connect to the nginx HTTP service at the server name or IP address you provided. If you are unable to connect, check that the nginx service is running and properly configured. If you receive a 502 (bad gateway) error, this indicates that gunicorn is misconfigured or not running.

Please keep in mind that the configurations provided here are bare minimums required to get NetBox up and running. You will almost certainly want to make some changes to better suit your production environment.

Upgrading

As with the initial installation, you can upgrade NetBox by either downloading the lastest release package or by cloning the master branch of the git repository. Several important steps are required before running the new code.

First, apply any database migrations that were included with the release. Not all releases include database migrations (in fact, most don't), so don't worry if this command returns "No migrations to apply."

# ./manage.py migrate

Second, collect any static file that have changed into the root static path. As with database migrations, not all releases will include changes to static files.

# ./manage.py collectstatic

Finally, restart the WSGI service to run the new code. If you followed this guide for the initial installation, this is done using supervisorctl:

# sudo supervisorctl restart netbox
