<\/p>\nInstalling Python on AlmaLinux 9 is a simple process. This article will guide you through the installation process, and you\u2019ll also set up a Python virtual environment as a bonus!<\/p>\n
Python is a versatile programming language you can use to create web applications, desktop applications, scripts, and many other types of programs. It is also a popular language for scientific computing, data analysis, artificial intelligence, and more. Basically, you can do almost anything with it.<\/p>\n
AlmaLinux is a production-grade enterprise operating system that is binary-compatible with Red Hat Enterprise Linux. It was initially released on March 2021 by CloudLinux to provide a community-supported spiritual successor to CentOS Linux.<\/p>\n
In this tutorial, you'll set up a programming environment for Python 3 on your AlmaLinux server.<\/p>\n
<\/p>\n
Before you install Python on AlmaLinux, you need:<\/p>\n
sudo<\/code> privileges. You can get affordable, and powerful AlmaLinux servers from our website<\/a>, and you can check out our How to access your server using SSH<\/a> guide to learn how to access your server and create a sudo<\/code> user.<\/li>\n<\/ul>\nStep 1 - Updating your System<\/h2>\n
Before installing Python on Alamalinux, you first need to update the packages to the latest available versions using the following command:<\/p>\n
sudo dnf update -y<\/code><\/pre>\nOnce the update is done, you should see the following output:<\/p>\n

<\/p>\n
Step 2 - Installing Python on AlmaLinux 9<\/h2>\n
To install Python 3.12 on your AlmaLinux server, first install the packages necessary to build Python 3.12 using the following command:<\/p>\n
sudo dnf install gcc openssl-devel bzip2-devel libffi-devel zlib-devel wget make tar -y<\/code><\/pre>\nYou should see the following output:<\/p>\n
![\"installing](\"https:\/\/www.ssdnodes.com\/wp-content\/uploads\/2024\/05\/Installed.webp\")
<\/p>\n
Next, download the Python 3.12 archive package from the official Python website with wget<\/code>:<\/p>\nwget https:\/\/www.python.org\/ftp\/python\/3.12.3\/Python-3.12.3.tar.xz<\/code><\/pre>\nOnce the download finishes, extract the archive package using the tar<\/code> command:<\/p>\ntar -xf Python-3.12.3.tar.xz<\/code><\/pre>\nA new Python-3.12.3<\/code> directory will appear, navigate to it using cd<\/code>:<\/p>\ncd Python-3.12.3<\/code><\/pre>\nRun the configuration file to check that all dependencies are available on your system:<\/p>\n
.\/configure --enable-optimizations<\/code><\/pre>\n![\"python](\"https:\/\/www.ssdnodes.com\/wp-content\/uploads\/2024\/05\/optimizations.webp\")
<\/p>\n
This check will take a few minutes. Once it finishes, use the make<\/code> command to start building Python:<\/p>\nmake -j 2<\/code><\/pre>\nNote:<\/strong> the -j<\/code> flag sets the number of CPU cores the make<\/code> command will use, it is recommended to use all the cores that are available in your server to speed up the build process, use the nproc<\/code> command to get the number of cores you have on your server, and use that number in the command above.<\/p>\nOnce the build process finishes, run the following command to install the Python package on your system:<\/p>\n
sudo make install<\/code><\/pre>\nNow that Python 3.12 is installed on your AlmaLinux server, you can check your Python version by running the following command:<\/p>\n
python3 -V<\/code><\/pre>\nYou'll receive your Python version:<\/p>\n
![\"Python](\"https:\/\/www.ssdnodes.com\/wp-content\/uploads\/2024\/05\/python-version.webp\")
<\/p>\n
With this, you have Python installed on your AlmaLinux 9 server and you can now create a virtual environment.<\/p>\n
Step 3 - Creating a Python Project Under a Virtual Environment<\/h2>\n
Python virtual environments allow you to have multiple isolated Python environments on one computer. This is useful for projects that require different versions of Python, or for projects that you don't want to contaminate with code from other projects. This ensures that each Python project is isolated from your other projects, so that conflict between dependencies does not occur.<\/p>\n
To create a Python programming environment, create a project directory somewhere in your system:<\/p>\n
mkdir myproject<\/code><\/pre>\nNavigate to your directory:<\/p>\n
cd myproject<\/code><\/pre>\nThen use the python -m venv<\/code> command line to create a new virtual environment inside your project folder:<\/p>\npython3 -m venv env<\/code><\/pre>\nThis will create a new directory called env<\/code>, which contains the dependencies you install while your virtual environment is activated. Here, we call this virtual environment directory env<\/code>, which is a name commonly used for Python virtual environment directories, but you can change it to another name if you wish.<\/p>\nNote:<\/strong> You can create as many virtual environments as you want, and it is highly recommended to create a virtual environment for each new Python project.<\/p>\nTo use this new environment and isolate your code and dependencies from the main AlmaLinux system's Python installation, you need to activate it with the following command. Change env<\/code> with the name of your virtual environment folder:<\/p>\nsource env\/bin\/activate<\/code><\/pre>\nYour command line should now have an (env)<\/code> prefix indicating that your virtual environment is activated.<\/p>\nTo install a Python package using pip<\/code>, you can use the following command:<\/p>\npip install package<\/code><\/pre>\nWith package<\/code> being the name of the Python package you wish to install.<\/p>\nFor example, to install the Django web framework, you can use the following command:<\/p>\n
pip install django<\/code><\/pre>\nWith this, you now have a Python programming environment ready, and you can now manage your Python packages inside isolated virtual environments.<\/p>\n
Step 4 - Creating a Small Python Program<\/h2>\n
With your virtual environment activated inside your project folder, you can now write Python code and install dependencies, and run them in an isolated box without interfering with the Python system installation on your AlmaLinux server.<\/p>\n
To edit files, you will need to first install the nano<\/code> editor:<\/p>\nsudo dnf install nano -y<\/code><\/pre>\nOnce nano<\/code> is installed on your system. You can now use it to edit Python files.<\/p>\nLet's create a small Python program called hi.py<\/code> that displays a Hello, World!<\/code> text:<\/p>\nnano hi.py<\/code><\/pre>\nType the following code into it:<\/p>\n
print(\"Hello, World!\")<\/code><\/pre>\nSave and close the file by pressing CTRL + X<\/code>, then Y<\/code> and ENTER<\/code>.<\/p>\nNow, run the program using the python<\/code> command:<\/p>\npython hi.py<\/code><\/pre>\nYou should receive the following output:<\/p>\n
Hello, World!<\/code><\/pre>\nNote:<\/strong> To deactivate your Python programming environment, use the following command:<\/p>\ndeactivate<\/code><\/pre>\nWith this, you now have a working programming environment for your Python projects.<\/p>\n
Congrats!<\/h2>\n
