Installing the latest version of Python on CentOS

CentOS Python

Using another OS?

Select the desired version or distribution.

Python is the popular high-level programming language, which is universal, fast and used in many projects, including large ones.

Installing the fresh variant of the libraries for supporting Python language in CentOS operating system is not difficult, especially if you follow everything in stages. In this tutorial, we will build version 3.10.11 from sources.

Updating Operating System Packages

Before updating Python directly, we update the operating system. Navigate terminal then execute:

sudo dnf update
sudo dnf upgrade

Updating the operating system

Installing Python on CentOS

To work with Python you need to install it on your computer, which can be a non-trivial task for Linux newbies. At this point, we'll walk via the installation step by step and provide detailed tutorial with commands and descriptions of each step.

Installing additional packages

If your system does not have the "wget" module, execute the commands one after the other:

sudo yum search wget
sudo yum install wget

The result of successful command execution

For further work, you need to get packages:

yum install gcc yum-utils zlib-devel python-tools cmake git pkgconfig -y --skip-broken

After successfully completing the installation, let's install the "Development Tools"

yum groupinstall -y "Development Tools" --skip-broken

To continue, you must go to the directory:

cd /usr/src

Loading source files

We get the latest version from the Python.org website. Visiting it, under "Downloads\Source code" copy the download link we found and need. Then run in the terminal, pasting in the just copied link:

wget https://www.python.org/ftp/python/3.11.3/Python-3.11.3.tgz

After downloading, you must retrieve the contents of the archive. You can use this command to do so:

tar xzf Python-3.11.3.tgz

Downloading and unpacking the archive with the source code

Navigate to the resulting Python-3.11.3 folder and install directly from the source code:

./configure

Complete the installation by executing the commands one after the other:

make
make install

Make sure the update is successful by sending a line to the terminal:

python3 --version

If version 3.11.x of Python is displayed, then all previous steps have gone correctly! It is now possible to use the universal programming language for your own purposes.

Python version update

If you already have an earlier version of Python, follow the steps below.

Installing additional Python packages

In order to perform a Python version upgrade, a few new packages must be supplied in addition. Send commands to the terminal:

yum groupinstall -y "Development Tools" --skip-broken
wget https://public-yum.oracle.com/public-yum-ol6.repo -O /etc/yum.repos.d/public-yum-ol6.repo

Installing additional packages

dnf --enablerepo=powertools install libpcap-devel

Установка дополнительных пакетов

sudo dnf install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel libffi-devel
