How to Install wger on nixOS

In this tutorial, we will go over the steps to install wger, a free, open-source web application that manages your personal fitness and exercise routines, on a nixOS Latest system.

Prerequisites

Before proceeding with this tutorial, you will need:

• A nixOS Latest installation. You can download the latest version from the official website here.

Step 1: Update the System

Start by updating the system to ensure you have the latest software versions and security patches.

sudo nix-channel --update
sudo nixos-rebuild switch

Step 2: Install Dependencies

Before we can move on to installing wger, we need to install its dependencies. Run the following command:

sudo nix-env -i python38 python38Packages.pip python38Packages.virtualenv

This command installs Python 3.8, Pip, and Virtualenv, which will be used to create a virtual environment for wger.

Step 3: Configure the Database

wger uses a PostgreSQL database to store data. We need to create a new user and a new database for wger to use.

sudo su - postgres

createuser --interactive

When prompted, enter the name of the new user and select Y for superuser permissions.

createdb wger

This will create a new database called wger.

Step 4: Install wger

Start by cloning the latest version of wger from the official GitHub repository:

git clone https://github.com/wger-project/wger.git
cd wger

Create a new virtual environment for wger:

virtualenv -p python3.8 venv

Activate the virtual environment:

source venv/bin/activate

Install wger and its dependencies:

pip install -r requirements.txt

Configure wger by creating a new local_settings.py file:

cp local_settings.py.example local_settings.py

Open the local_settings.py file and modify the following settings:

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql_psycopg2',
        'NAME': 'wger',
        'USER': '<database_username>',
        'PASSWORD': '<database_password>',
        'HOST': '',
        'PORT': '',
    }
}

Replace <database_username> with the username you created in Step 3 and <database_password> with a strong password of your choice.

Step 5: Run the Application

Before we can start wger, we need to migrate the database by running the following command:

python manage.py migrate

Start the web server:

python manage.py runserver

Open your web browser and navigate to http://localhost:8000. You should see the wger homepage.

Conclusion

In this tutorial, we went over the steps to install wger on a nixOS Latest system. With wger installed, you can now manage your personal fitness and exercise routines right from your web browser.
