In this tutorial, we will show you how to install Python on AlmaLinux 9. Python 3.12 is the latest major release of the Python programming language. It comes with several new features, optimizations, and library improvements.
This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘
sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the Python programming language on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux or RHEL-based.
- A server running one of the following operating systems: AlmaLinux 9.
- It’s recommended that you use a fresh OS install to prevent any potential issues.
- SSH access to the server (or just open Terminal if you’re on a desktop).
- An active internet connection. You’ll need an internet connection to download the necessary packages and dependencies for Python.
- Python requires certain permissions that can only be granted to a superuser or a user with
sudoprivileges. Ensure that you have the necessary administrative access.
Install Python on AlmaLinux 9
Step 1. Before diving into the installation process, it’s crucial to ensure your system is up-to-date. This step helps avoid potential conflicts and ensures a smooth installation process. To update your system packages, open your terminal and type the following command:
sudo dnf clean all sudo dnf update
Once the system is updated, we need to install some essential development tools and libraries. These tools are necessary for building and installing Python from source. Execute the following command to install the required packages:
sudo dnf install gcc openssl-devel bzip2-devel libffi-devel zlib-devel
Step 2. Installing Python 3.12.1 on AlmaLinux 9.
First, download the latest Python 3.12 source code tarball from the official website:
Verify the integrity of the downloaded file using SHA-256 checksum or GPG signature.
Next, extract the compressed tarball using the following command:
tar xzf Python-3.12.1.tgz
This will create a
Python-3.12.1 directory. Navigate into it:
Before compiling the source code, we need to run the configuration script. This script checks the system for all necessary dependencies and prepares the build environment. To run the configuration script with optimizations, use the following command:
Next, compile the source code using the
make command. The
-j option allows you to specify the number of cores to use, speeding up the build process. For example, to use 4 cores, run:
Once the build process completes, install Python 3.12 using the
make altinstall command:
sudo make altinstall
After the installation, it’s important to verify that Python 3.12 was installed correctly. To do this, check the Python version using the following command:
Step 3. Upgrade Pip and Install Modules.
Some Python modules may not be available yet for Python 3.12. So upgrade
python3.12 -m pip install --upgrade pip
Step 4. Setting Up a Python Virtual Environment.
Working within a virtual environment is a best practice in Python development. It isolates your Python projects and their dependencies, preventing conflicts between different project dependencies. To create a virtual environment for your Python 3.12.1 installation, use the
/usr/local/bin/python3.12.1 -m venv myenv
This command creates a new virtual environment named
myenv. To activate the virtual environment, use the following command:
With the virtual environment activated, you can now install and manage Python packages isolated from the system Python.
Congratulations! You have successfully installed Python. Thanks for using this tutorial for installing Python programming language on your AlmaLinux 9 system. For additional help or useful information, we recommend you check the official Python website.
