How To Install Python 3.11 on AlmaLinux 9

In this guide, we intend to teach you How To Install Python 3.11 on AlmaLinux 9.

Python is a computer programming language often used to build websites and software, automate tasks, and conduct data analysis. Python is a general-purpose language, meaning it can be used to create a variety of different programs and isn’t specialized for any specific problems. This versatility, along with its beginner-friendliness, has made it one of the most-used programming languages today.

The latest stable release of Python is 3.11 which you learn to install it on your AlmaLinux server in this guide.

Steps To Install Python 3.11 on AlmaLinux 9

To complete this guide, you must log in to your server as a non-root user with sudo privileges. To do this, you can follow our guide on Initial Server Setup with AlmaLinux 9.

Set up Python 3.11 on AlmaLinux 9

First, you need to update your local package index with the following command:

sudo dnf update -y

Install Dependencies

Then, install the required packages and dependencies on your server with the command below:

sudo dnf install gcc openssl-devel bzip2-devel libffi-devel zlib-devel wget make tar -y

Download Python 3.11

Now you need to visit the Python Downloads page to check the latest stable version and download it with the following wget command:

sudo wget https://www.python.org/ftp/python/3.11.1/Python-3.11.1.tgz

Extract your downloaded file with the following command:

sudo tar -xf Python-3.11.1.tgz

Next, switch to your source directory:

cd Python-3.11.1

Run Configuration Script

At this point, you need to run the configuration script to be sure that all dependencies are ready for the Python 3.11 installation to work on AlmaLinux 9:

./configure --enable-optimizations

–enable-optimizations option is for use after all debugging and maximum performance with minimum run-time checks is required.

Build and Install Python 3.11

After the configuration script is completed, you need to start your build process with the following command:

make -j 2

The -j option is related to the number of cores in your system to speed up the build time.

To find how many cores you have on your system, you can use the following command:

nproc

The build process takes some time to complete.

When it is finished, you can install Python 3.11 source on AlmaLinux 9 with the following command:

sudo make altinstall

When your installation is completed, you can verify your Python 3.11 installation on AlmaLinux 9 by checking its version:

python3.11 --version

Output
Python 3.11.1

To ensure that Python 3.11 is working correctly, you can create a test Python project.

Test Python Installation on AlmaLinux 9

First, you need to create the Python project directory and switch to it with the following command:

mkdir ~/test_app && cd ~/test_app

Then, from the project directory, create a virtual environment with the following command, here we named it test_app_venv:

python3.11 -m venv test_app_venv

Next, activate your virtual environment with the command below:

source test_app_venv/bin/activate

You will see that your shell prompts changes to the name of your virtual environment.

For example, you can install Apache-Airflow inside your virtual environment with the pip package manager for Python:

pip install apache-airflow

To exit from your virtual environment you can use the following command:

deactivate

Conclusion

At this point, you learn to Install Python 3.11 on AlmaLinux 9 and create a test Python project.

I hope you enjoy it.
