Python zipapp web apps

What's a zipapp?

This concept is very much like .jar or .war archives in Java.

NOTE: The built .pyz zipapp can run on both Python 2 & 3 but you can only build .pyz zipapps with Python 3.5 or later.

Develop a Flask Application using MariaDB, Redis and Celery on Ubuntu 14.04

@credit Yan Zhu (https://github.com/nina-zhu)

Introduction

Before you start this guide, you should run through the "How To Serve Flask Applications with uWSGI and Nginx on Ubuntu 14.04" guide. This is necessary in order to set up virtualenv, uWSGI and Nginx. In that guide, we developed a very simple flask application having just 1 file "firstflask.py" with only 9 lines of code, it is a sample for showing you the general steps. In this guide, we will create a complete user session listing application, with login, logout functionality. We will use MariaDB to store the users records, and use Redis to store the session data and background tasks.

Let's get started.

Set Up the MariaDB Server
