1. Step 1) creating a virtual environment for the project

see if the package is installed

$ sudo apt search python3-venv

if not installed, install package

$ sudo apt install python3-venv

now install module venv of python in your virtual environment directory

$ python3 -m venv [directory_path]

2. Step 2) enter into our virtual environment for config

$ source .pyvenv/bin/activate

list package python into environment

([directory_name])$ pip list

update package python into environment

([directory_name])$ pip install -U [package_1 package_2 ...]

install serve gunicorn

([directory_name])$ pip install gunicorn

install framework "falcon" for application python api Rest

([directory_name])$ pip install falcon

exit our virtual environment

([directory_name])$ deactivate

3. Step 3) create file .sh for run server gunicorn

$ touch start.sh

content basic for .sh file

#!/bin/bash
source [directory_name]/bin/activate
exec [directory_name]/bin/gunicorn -w 3 -t 99999 -b '0.0.0.0:8082' [name_file.py:class]
