Weather Prediction System

A website that uses machine learning to predict the weather.

What it looks like:

Features

• Flask web server for Debian/Ubuntu
• Login and signup page
• Cookie usage when user logs in
• Database for user login credentials
• Password hashing
• Random Forest Classifier model that takes user's inputs and predicts weather

Setup Development Server

To create a quick-and-dirty server, follow these instructions:

1. Install Python and pip
2. pip install -r requirements.txt
3. Run the shell script
4. Go to 127.0.0.1:5000 for localhost or the private IP address of the server in a browser

Setup Production Server

To create a server the proper way, follow these instructions:

1. Install Python 3.10.4, pip, and venv. Pyenv is preferred for this.
2. apt install nginx git
3. git clone https://github.com/WillChamness/WeatherPredictionSystem && cd WeatherPredictionSystem
4. python -m venv env and source env/bin/activate
5. Install gunicorn with pip or apt. Pip is preferred and will be assumed for the gunicorn config.
6. pip install -r requirements.txt
7. Change the last line in app.py to app.run(host='0.0.0.0', debug=False)
8. Use the Nginx configuration below
9. Use the gunicorn daemon configuration below
10. Go to the IP address of the server in a browser

Nginx Config

Create /etc/nginx/sites-enabled/flask-app and add the following:

server {
        listen 80 default_server;

        location / {
                proxy_pass http://127.0.0.1:8000; # port number not a typo
                proxy_set_header Host $host;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        }
}

Then unlink the default config and test the syntax:

sudo unlink /etc/nginx/sites-enabled/default
sudo nginx -t

If there are no errors, reload Nginx:

sudo nginx -s reload

Gunicorn Config

Create /etc/systemd/system/weather-prediction.service and add the following:

[Unit]
Description=Flask App

[Service]
Type=simple
ExecStart=/path/to/WeatherPredictionSystem/env/bin/gunicorn --chdir /path/to/WeatherPredictionSystem/ app:app

[Install]
WantedBy=multi-user.target

Then start and check the service:

sudo systemctl start weather-prediction
sudo systemctl status weather-prediction

If there are no errors, enable the service:

sudo systemctl enable weather-prediction
