Pretix is an open-source software that allows you to sell tickets for events and organize conferences. In this tutorial, I will show you how to install Pretix on your Fedora CoreOS system.
Before we get started, you must have a few things:
First, we need to install some dependencies for running Pretix. Use the following command to install them.
sudo rpm-ostree install python3 python3-devel git gcc
Next, we will clone the latest version of Pretix from its official repository. Use the following command:
git clone https://github.com/pretix/pretix
To install Pretix's dependencies, we will use the Python virtual environment. Run the following commands to create a virtual environment:
python3 -m venv /opt/pretixenv
source /opt/pretixenv/bin/activate
Now, navigate to the cloned Pretix repository, and install the required Python packages using the requirements/production.txt file:
cd pretix/src
pip install -r requirements/production.txt
In order to store the Pretix data, we need to set up a PostgreSQL database. First, install the PostgreSQL package, then create the database and user using the following commands:
sudo rpm-ostree install postgresql-server postgresql-contrib
sudo postgresql-setup initdb
sudo systemctl start postgresql
sudo systemctl enable postgresql
sudo -i -u postgres
CREATE USER pretix WITH PASSWORD 'pretixpassword';
CREATE DATABASE pretix OWNER pretix;
\q
exit
Now, we need to configure Pretix. Rename the pretix.cfg.example file to pretix.cfg:
cd ../..
mv pretix/pretix/cfg/example.cfg pretix/pretix/cfg/pretix.cfg
Open the pretix.cfg file with your favorite text editor and modify the following values:
ALLOWED_HOSTS = ['yourdomain.com'] # Replace yourdomain.com with your actual domain name
DB_NAME = 'pretix'
DB_USER = 'pretix'
DB_PASSWORD = 'pretixpassword'
DEBUG = False
SECRET_KEY = '<some-random-string>'
Save and close the file.
Finally, we are ready to run the Pretix server. Make sure you have activated the Python virtual environment using the following command:
source /opt/pretixenv/bin/activate
Now, navigate to the src directory and run the following commands:
python manage.py migrate
python manage.py collectstatic --noinput
python manage.py createsuperuser # This is to create an admin account for Pretix
This will migrate the database schema, collect the staticfiles, and create the admin account. Set the superuser account email and password as prompted by the command.
To run the Pretix server, use the following command:
python manage.py runserver 0.0.0.0:8000
You should now see the Pretix server running on port 8000. If you want to run it on a different port, replace 8000 with your preferred port number.
Running the Pretix server with HTTPS enables a secure connection between the server and client browsers. To enable HTTPS, you need to have an SSL/TLS certificate from a trusted Certificate Authority (CA). You can obtain a free SSL/TLS certificate from Let's Encrypt by installing Certbot.
Use the following commands to install Certbot and obtain a certificate:
sudo dnf install certbot
sudo certbot certonly --standalone --preferred-challenges http --agree-tos --email your-email@example.com -d yourdomain.com
Replace your-email@example.com and yourdomain.com with your actual email and domain name.
Once the certificate is installed, configure the server to use HTTPS by running the following command:
python manage.py changepassword --user pretix --password <new-password-for-pretix-database>
python manage.py migrate
python manage.py collectstatic --noinput
python manage.py runsslserver 0.0.0.0:443 --certificate /etc/letsencrypt/live/yourdomain.com/fullchain.pem --key /etc/letsencrypt/live/yourdomain.com/privkey.pem --ssl-cert-frontend='modern' --ssl-header-frontend='X-Forwarded-Proto: https'
In the above command, replace yourdomain.com with your actual domain name, and set a new password for the Pretix database.
The Pretix server should now be accessible over HTTPS on port 443.
You have learned how to install Pretix on your Fedora CoreOS machine. You can now use it to sell tickets for events and manage conferences.
If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
Alternatively, for the best virtual desktop, try Shells!
