How to Install Pretix on Elementary OS Latest

Pretix is an open-source ticketing/registration software that is used widely by event organizers. In this tutorial, we will learn how to install Pretix on Elementary OS Latest.

Prerequisites

Before you start, make sure you have the following:

Sudo privileges on your system
Access to the terminal

Step 1: Update your System

Before we start installing Pretix, it's essential to update our system to the latest packages. To do that, open up the terminal and run the following command:

$ sudo apt update && sudo apt upgrade

This command will update your system's package repositories and upgrade the existing packages to the latest versions.

Step 2: Install Required Dependencies

Pretix requires several dependencies to be installed on your system before it can be installed successfully. Run the following command to install these dependencies:

$ sudo apt install git python3-dev python3-pip python3-setuptools virtualenv nodejs npm build-essential libxml2-dev libxslt1-dev libjpeg-dev zlib1g-dev libpq-dev libssl-dev libffi6 libffi-dev libpcre3-dev swig

Step 3: Install PostgreSQL

Pretix requires a PostgreSQL server installed on your system to store its data. Run the following command to install the PostgreSQL server:

$ sudo apt install postgresql-12 postgresql-server-dev-12

After the installation completes, start and enable the PostgreSQL service with the following commands:

$ sudo systemctl start postgresql
$ sudo systemctl enable postgresql

Step 4: Create a PostgreSQL User and Database for Pretix

After installing PostgreSQL, create a new user and database for the Pretix installation. Run the following commands to create a new PostgreSQL user named pretixuser and a database named pretixdb:

$ sudo -u postgres createuser -P pretixuser
$ sudo -u postgres createdb -O pretixuser pretixdb

Step 5: Clone Pretix Repository

Now, we need to clone the Pretix repository from the GitHub repository. Change the directory to your preferred directory and run the following command to clone the repository:

$ git clone https://github.com/pretix/pretix.git

Step 6: Create a Virtual Environment and Install Pretix

Pretix requires Python 3.7 or higher to run. To ensure that we have the correct version of Python, we will create a virtual environment and install the required packages in it.

Change the directory to the cloned repository by running cd pretix. Then, create a new virtual environment:

$ virtualenv --python=python3 venv

Activate the virtual environment by running:

$ . venv/bin/activate

Install the required packages for Pretix in the virtual environment by running the following command:

$ pip install -r requirements.txt

Step 7: Configure Your Settings

Before we can run Pretix, we need to configure some settings. First, navigate to the src/pretix/settings directory by running:

$ cd src/pretix/settings/

Create a copy of the default_settings.py file and name it local_settings.py by running:

$ cp default_settings.py local_settings.py

Open the local_settings.py file in a text editor and make the following changes:

Change DATABASES settings to match your PostgreSQL database settings, such as:

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql_psycopg2',
        'NAME': 'pretixdb',
        'USER': 'pretixuser',
        'PASSWORD': 'your_password_here',
        'HOST': 'localhost',
        'PORT': '5432',
    }
}

Configure ALLOWED_HOSTS by adding your domain or IP address:

ALLOWED_HOSTS = ['your_domain_or_ip_address_here']

Set SECRET_KEY to a random string by generating a new key with the following command:

$ python -c "import secrets; print(secrets.token_urlsafe())"

Set EMAIL_BACKEND to django.core.mail.backends.smtp.EmailBackend and configure your email settings, such as:

EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
EMAIL_HOST = 'your_email_host'
EMAIL_PORT = 587
EMAIL_HOST_USER = 'your_email_address'
EMAIL_HOST_PASSWORD = 'your_email_password'
EMAIL_USE_TLS = True

Step 8: Apply Database Migrations

Now that we have our database configured and ready to go, we need to apply the database migrations. Go back to the pretix folder by running cd ../.. and then run the following command:

$ python src/manage.py migrate

Step 9: Create a Superuser Account

Create a superuser account to manage the Pretix administration by running the following command:

$ python src/manage.py createsuperuser

Follow the prompts to create the superuser account.

Step 10: Collect Static Files

Pretix uses static files such as CSS, JS, images, and other assets to display correctly. Collect these static files by running:

$ python src/manage.py collectstatic

Step 11: Run the Development Server

Now we are ready to run Pretix. Start the development server by running:

$ python src/manage.py runserver

You should see output similar to the following:

Performing system checks...
System check identified no issues (0 silenced).
January 08, 2022 - 11:32:38
Django version 3.2.9, using settings 'pretix.settings.dev'
Starting development server at http://127.0.0.1:8000/
Quit the server with CONTROL-C.

Open your web browser and go to http://127.0.0.1:8000/. You should now see the Pretix homepage.
