How to Install Pastila on Fedora Server Latest

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.

Prerequisites

Before proceeding with this tutorial, make sure you have the following prerequisites on your system:

• A Fedora Server Latest installation
• A user account with sudo privileges
• Python 3 and pip package manager installed on your system.

Step 1: Install PostgreSQL

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

Step 2: Install Python Libraries

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

Step 3: Create Pastila Application

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.

Step 4: Configure PostgreSQL

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.

Step 5: Configure the Pastila Application

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.

Step 6: Run the Pastila Application

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!
