Cyberpanel allows deployment of Django application easily. This guide will take you through a step by step guide on how this can be achieved.

At the end, you will know
1. How to Host a Django app on Cyberpanel with Openlitespeed.
2. Install Multiple Versions of Python for your application.
3. Configure Virtual host settings for Openlitespeed be able to serve  your Django app.

We shall deploy our Django app on Cyberpanel - on the URL: https://djp.lintsawa.com/

In this guide I will be using Almalinux 8.

Step 1: Installing Python. 
Here we shall install the same python version as we used on localhost.

Installing Python First. Current Python Version on Almalinux is 3.6 and I want to use 3.8 as that is what I used for the project.
=========================

Install Dependencies.

Ubuntu
----------
$ sudo apt-get install -y make build-essential libssl-dev zlib1g-dev \
libbz2-dev libreadline-dev libsqlite3-dev wget curl llvm libncurses5-dev \
libncursesw5-dev xz-utils tk-dev libffi-dev liblzma-dev python3-openssl

Almalinux
----------
yum -y install gcc zlib-devel bzip2 bzip2-devel readline-devel sqlite sqlite-devel openssl-devel xz xz-devel libffi-devel mysql-devel pkgconfig libpq-devel

Install Development packages.

yum -y groupinstall "Development Tools"

Step 2: Download and Install pyenv 
Pyenv will be used to allows us manage multiple versions of python and easy installation of any version we need.

Will be using this to install python 3.8.20

curl https://pyenv.run | bash

Enable pyenv

echo 'export PYENV_ROOT="$HOME/.pyenv"' >> ~/.bashrc

echo 'command -v pyenv >/dev/null || export PATH="$PYENV_ROOT/bin:$PATH"' >> ~/.bashrc

echo 'eval "$(pyenv init -)"' >> ~/.bashrc

Confirm pyenv is working by typing commands below.

pyenv

pyenv install --list - To show available versions

pyenv install 3.8.20 - To install the selected version.

All done.

pyenv versions

Step 3: Installing wsgi
================

curl -O https://www.litespeedtech.com/packages/lsapi/wsgi-lsapi-2.1.tgz
tar xf wsgi-lsapi-2.1.tgz
ls
cd wsgi-lsapi-2.1/
ls

Here we need to compile wsgi with our new python version hence we switch to this version.

pyenv global 3.8.20

python3 --version
ls
Switch our python version from 3.6 to the newly installed one.

pyenv global 3.8.20
pyenv versions
python3 --version

Build wsgi with the new python version.

python3 ./configure.py
make
cp lswsgi /usr/local/lsws/fcgi-bin/
cd  /usr/local/lsws/fcgi-bin/

Step 4: Create a website on Cyberpanel.
==============================

Upload our files to public_html folder
Navigate via SSH to cd /home/djp.lintsawa.com/public_html/

Create and activate virtual env

python3 -m venv /home/djp.lintsawa.com/public_html/

source /home/djp.lintsawa.com/public_html/bin/activate

Navigate to your projects directory.

cd portfolio-website-main/
ls
cat requirements.txt

pip install -r requirements.txt

python manage.py migrate
python manage.py collectstatic

Go back to Cyberpanel dashboard > Websites > List Website > Manage > Configurations >vHost and Add the context below to vHost section of your domain.

Add Context.
=================

context / {
    type            appserver
    location        /home/djp.lintsawa.com/public_html/portfolio-website-main
    binPath         /usr/local/lsws/fcgi-bin/lswsgi
    appType         wsgi
    startupFile     Portfolio/wsgi.py
    envType         1
    env             LS_PYTHONBIN=/home/djp.lintsawa.com/public_html/bin/python3
}

All Done. Reload your site should be working well.

In case of Errors:
==========

tail -f /usr/local/lsws/logs/stderr.log

Done.
