Installing NetBox on Fedora CoreOS Latest

NetBox is an open-source web-based IPAM (IP Address Management) and DCIM (Data Center Infrastructure Management) tool used to manage network address space and other critical infrastructure components. In this tutorial, we will go through the steps to install NetBox on Fedora CoreOS Latest.

Prerequisites

Before proceeding, make sure you have the following:

A running instance of Fedora CoreOS Latest
A sudo user

Steps

Update the system:
```
sudo dnf update -y
```

Install the required system packages:

sudo dnf install -y python3 python3-pip python3-devel nginx redis redis-devel gcc git openssl-devel

Clone NetBox from Github:

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

Create a virtual environment and activate it:

python3 -m venv netboxenv

source netboxenv/bin/activate

Install the required Python packages:

cd netbox
pip install -r requirements.txt

Create a configuration file:

cp netbox/netbox/configuration.example.py netbox/netbox/configuration.py

Edit the configuration file with your preferences:

nano netbox/netbox/configuration.py

For example, update the following settings with your preferences:

ALLOWED_HOSTS = ['your.host.name']
SECRET_KEY = 'your-secret-key'

# Database
DATABASES = {
     'default': {
         'NAME': 'netbox',
         'USER': 'netbox',
         'PASSWORD': 'yourpassword',
         'HOST': 'localhost',
         'PORT': '',
         'ENGINE': 'django.db.backends.postgresql',
     },
 }

# Redis
REDIS = {
     'tasks': {
         'HOST': 'localhost',
         'PORT': 6379,
         'PASSWORD': '',
         'DATABASE': 0,
         'DEFAULT_TIMEOUT': 300,
     },
 }

Create the PostgreSQL database:

sudo -u postgres psql -c "CREATE DATABASE netbox;"
sudo -u postgres psql -c "CREATE USER netbox WITH PASSWORD 'yourpassword';"
sudo -u postgres psql -c "ALTER USER netbox CREATEDB;"
sudo -u postgres psql -c "GRANT ALL PRIVILEGES ON DATABASE netbox TO netbox;"

Migrate the database:
```
python3 manage.py migrate
```
Create a superuser:
```
python3 manage.py createsuperuser
```

Start the development server:

python3 manage.py runserver 0.0.0.0:8000

Open your web browser and navigate to http://your.host.name:8000/ to access the NetBox web interface.
Shutdown the development server by pressing CTRL + C.

Setup the Gunicorn launcher:

sudo cp contrib/gunicorn.py /etc/netbox/
sudo nano /etc/netbox/gunicorn.py

Edit the following lines:

bind = '127.0.0.1:8001'
worker_class = 'gevent'
workers = 4

Start Gunicorn service:

sudo cp contrib/gunicorn.service /etc/systemd/system/
sudo systemctl enable gunicorn
sudo systemctl start gunicorn
sudo systemctl status gunicorn

Setup the Nginx web server:

sudo cp contrib/nginx.conf.sample /etc/nginx/conf.d/netbox.conf
sudo nano /etc/nginx/conf.d/netbox.conf

Edit the following lines:

server {
    listen 80;
    server_name your.host.name;

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

    location / {
        proxy_pass http://localhost:8001;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    }
}

Start the Nginx service:

sudo systemctl enable nginx
sudo systemctl start nginx
sudo systemctl status nginx

Open your web browser and navigate to http://your.host.name/ to access the NetBox web interface.
