flask-apache-setup

This is a simple minimal guide that can be used to deploy flask using apache on a server.

Install Python3 and Apache with WSGI

sudo apt install python3-pip
sudo apt install python-dev
sudo apt install apache2 libapache2-mod-wsgi-py3

Install Python modules as required

sudo pip3 install requests flask pandas

Copy Basic Apache config for mycompany

<VirtualHost *:80>
		ServerName mywebsite.com
		ServerAdmin [email protected]
		WSGIScriptAlias / /var/www/mycompany/mycompany.wsgi
		<Directory /var/www/mycompany/mycompany/>
			Order allow,deny
			Allow from all
		</Directory>
		Alias /static /var/www/mycompany/mycompany/static
		<Directory /var/www/mycompany/mycompany/static/>
			Order allow,deny
			Allow from all
		</Directory>
		ErrorLog ${APACHE_LOG_DIR}/error.log
		LogLevel warn
		CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

Enable FlaskApp on Apache

sudo a2ensite mycompany
sudo systemctl reload apache2

Setup WSGI

cd /var/www/
mkdir -p mycompany/mycompany
sudo vi mycompany/mycompany.wsgi

----------------------------------------
#!/usr/bin/python3
import sys
import logging
logging.basicConfig(stream=sys.stderr)
sys.path.insert(0,"/var/www/mycompany/mycompany")

from mycompany import app as application
application.secret_key = 'Add your secret key'
----------------------------------------

sudo chmod -R www-data:www-data mycompany/
sudo chmod -R www-data:www-data mycompany/*
sudo service apache2 restart

Basic Flask App

sudo vi /var/www/mycompany/mycompany/init.py sudo vi /var/www/mycompany/mycompany/mycompany.py

from flask import Flask
app = Flask(__name__)

@app.route('/')
def demo():
    return F"<h1> My company is under construction, please check back later <h1>", 200

if __name__ == '__main__':
    app.run()
