Web Server Installation

We'll set up a simple WSGI 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 to enable service persistence.

!!! info Only Debian/Ubuntu instructions are provided here, but the installation process for CentOS/RHEL does not differ much. Please consult the documentation for those distributions for details.

# apt-get install -y gunicorn supervisor

Option A: nginx

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

# apt-get install -y nginx

Once nginx is installed, save the following configuration to /etc/nginx/sites-available/netbox. Be sure to replace netbox.example.com with the domain name or IP address of your installation. (This should match the value configured for ALLOWED_HOSTS in configuration.py.)

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"';
    }
}

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

To enable SSL, consider this guide on securing nginx with Let's Encrypt.

Option B: Apache

# apt-get install -y apache2

Once Apache is installed, proceed with the following configuration (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

To enable SSL, consider this guide on securing Apache with Let's Encrypt.

gunicorn Installation

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. If using CentOS/RHEL change the username from www-data to nginx or apache.

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

supervisord Installation

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

Then, 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.

!!! info 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.
