Pastila is a fast and lightweight web framework for developing web applications using Python. In this tutorial, we will be learning how to install and configure Pastila on a Fedora Server Latest operating system.
Before proceeding with this tutorial, make sure you have the following prerequisites on your system:
The first step is to install PostgreSQL, which is a relational database management system that Pastila uses to store data. To do this, run the following command:
sudo dnf install postgresql-server
After installing, initialize the database:
sudo postgresql-setup --initdb
Then start the PostgreSQL service:
sudo systemctl start postgresql
Finally, enable PostgreSQL to start at boot time:
sudo systemctl enable postgresql
Pastila requires some Python libraries to function correctly. To install them, run the following commands:
sudo dnf install python3 python3-pip
sudo dnf install python3-devel libpq-devel
Once the libraries are installed, use pip to install the following Python packages:
sudo pip install cython
sudo pip install pastila
sudo pip install psycopg2
To create a new Pastila application, run the following command:
pastila create myapp
This command will create a new directory called myapp, which contains the basic structure of a Pastila application.
After creating the Pastila application, it's time to configure PostgreSQL.
First, log in to the PostgreSQL server as the postgres user:
sudo su - postgres
psql
Then create a new database user and database:
CREATE USER myapp_user WITH PASSWORD 'password';
CREATE DATABASE myapp_db OWNER myapp_user;
Once the user and database are created, give the myapp_user user permission to access the myapp_db database:
GRANT ALL PRIVILEGES ON DATABASE myapp_db TO myapp_user;
Exit the PostgreSQL shell by typing \q and pressing Enter.
Next, go to the myapp directory that was created in Step 3 and open the settings.py file in your favorite text editor.
Here, replace the default database configuration with the following:
DATABASE_URI = 'postgresql://myapp_user:password@localhost/myapp_db'
Save and close the file.
To run the Pastila application, use the following command:
pastila run myapp
This command will start the Pastila development server and listen on port 5000.
Open your web browser and navigate to http://localhost:5000. You should see the default Pastila welcome page.
Congratulations, you have successfully installed Pastila on your Fedora Server Latest operating system!
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!
