REST APIs with Flask and Python - Setting up nginx and REST API

This video tutorial covers the installation and configuration of Nginx as a reverse proxy for a Flask application. It explains the steps to install Nginx on an Ubuntu server, configure firewall settings, and set up Nginx to work with a Flask app using uWSGI. The tutorial also includes creating a virtual environment and installing necessary Python packages.

What is the primary role of Nginx when used as a reverse proxy?

• To manage database connections

• To handle incoming requests and forward them to the application

• To serve static files

• To act as a firewall

Why is it necessary to run 'sudo apt-get update' before installing Nginx?

• To restart the server

• To install Nginx directly

• To update the package manager with the latest version numbers

• To clear the cache

What command is used to allow Nginx through the firewall?

• sudo UFW allow Nginx HTTP

• sudo firewall-cmd --add-service=nginx

• sudo iptables -A INPUT -p tcp --dport 80 -j ACCEPT

Why is it important to change the ownership of the application directory to the user 'Jose'?

• To prevent unauthorized access

• To allow the user 'Jose' to manage the application files

• To enable root access

• To improve server performance

What is the purpose of creating a virtual environment for the Python application?

What is the role of the 'requirements.txt' file in a Python project?

• To list all the files in the project

• To configure the server settings

• To list the project's dependencies

• To specify the Python version

Which package manager is used to install Python packages in the virtual environment?

• apt-get

• pip

• npm

• brew
