Introduction to the installation

What you need to have:

• Account on smarthost (the best is nvme series of packages)
• Django – version 4.2.1
• Python – version 3.9.16
• database – sqlite3
• SSH Access (you can enable your access on customer panel)
  
  
  
  

For the purposes of installation, the data required for the account

• Account name: janek
• Domain name: djdomena.pl (added in cPanel with generated SSL certificate)
• The name of the directory where the django applications will be – djapp

We start by logging into cpanel and looking for Software -> Setup Python App

We select the version of python, specify the path to the root directory of the application ( djapp ) and select our domain or subdomain.

We have chosen python 3.9

/home/janek/public_html/djdomain.pl/djapp

Domain : djdomain.pl

We click on CREATE

A virtual python environment and our djapp directory will be created.

Important! a message will be displayed on how to access virtualenv.

It is best to copy and save in a safe place.

We log in via ssh and use the source command:
source /home/janek/virtualenv/public_html/djdomena.pl/djapp/3.9/bin/activate && cd /home/janek/public_html/djdomena.pl/djapp

View after the command has been executed:

((djapp:3.9)) {janek@serwer:djapp}$

Logging out of virtualenv: deactivate command

Install django ( if the specific version is django==4.2.1 ) with the command pip install django

After installation, the result on the console:

((djapp:3.9)) {janek@serwer:djapp}$ pip install django

We also install whitenoise

pip install whitenoise

Without this package, access to the django-admin panel will not use CSS styles.

Informative in our catalog

/home/janek/public_html/djdomena.pl/djapp

there should be directories : public, tmp and the files manage.py and passenger_wsgi.py

We create our first app with the command:

django-admin startproject mysite .

Next, we will first look at the passenger_wsgi.py file

You will need to customise/edit it with the following code

import imp
import os
import sys

sys.path.insert(0, os.path.dirname(__file__))
wsgi = imp.load_source('wsgi', 'mysite/wsgi.py')
application = wsgi.application

The most important is the line

wsgi = imp.load_source('wsgi', 'mysite/wsgi.py')

mysite is our app that we added a step earlier

Then we edit mysite/settings.py

We will be adding or editing

ALLOWED_HOSTS = ['djdomena.pl','www.djdomena.pl']

Configuration of whitenoise in the MIDDLEWARE section

"whitenoise.middleware.WhiteNoiseMiddleware",

This is what whitenoise should look like in the 2nd position:

MIDDLEWARE = [ 
 'django.middleware.security.SecurityMiddleware',
 "whitenoise.middleware.WhiteNoiseMiddleware",
 'django.contrib.sessions.middleware.SessionMiddleware',
 'django.middleware.common.CommonMiddleware',
 'django.middleware.csrf.CsrfViewMiddleware',
 'django.contrib.auth.middleware.AuthenticationMiddleware',
 'django.contrib.messages.middleware.MessageMiddleware',
 'django.middleware.clickjacking.XFrameOptionsMiddleware', 
]

STATIC_ROOT = BASE_DIR / 'static'

We are launching our app to work

We need to be in the djapp directory

((djapp:3.9)) {janek@serwer:djapp}$ python manage.py migrate

Operations to perform:
Apply all migrations: admin, auth, contenttypes, sessions

Applying auth.0012_alter_user_first_name_max_length… OK
Applying sessions.0001_initial… OK

The next command is to add css styles to the django panel:

python manage.py collectstatic

((djapp:3.9)) {janek@serwer:djapp}$ python manage.py collectstatic
125 static files copied to '/home/janek/public_html/djdomena.pl/djapp/static'.

Add the user with the command:

python manage.py createsuperuser

((djapp:3.9)) {janek@serwer:djapp}$ python manage.py createsuperuser
Nazwa użytkownika (leave blank to use 'janek'): janek
Adres e-mail: janek@djdomena.pl
Password:
Password (again):
Superuser created successfully.
((djapp:3.9)) {janek@serwer:djapp}$

when entering the password, nothing is shown on the console.

We are almost at the very end!

Restarting the application can be done in 2 ways: in cpanel by clicking on restart:

or create a restart.txt file and the server will reload itself

touch tmp/restart.txt

We check our site should be a basic template like this one:

We can also log into the panel – the address is the name of our domain + admin/ ( Example https://djdomena/admin/ )

We have reached the end there are still a few prompts left but that will be in the next article.

Have fun with django.
