Installation

Method 1 – pip install

Requires Python ≥2.7 or ≥3.4. Use pyenv + venv to manage versions.

$ python3 --version
Python 3.7.0

# Create virtual environment
$ python3 -m venv venv

# Activate
$ source venv/bin/activate

Linux/macOS:

# Install domain-admin
$ pip install gunicorn domain-admin

# Run
$ gunicorn --bind '127.0.0.1:8000' 'domain_admin.main:app'

Windows:

# Install domain-admin
$ pip install waitress domain-admin

# Run
$ waitress-serve --listen=127.0.0.1:8000 'domain_admin.main:app'

Default access: http://127.0.0.1:8000 (admin / 123456). It is strongly recommended to change the default password after login.
