Here at LinuxAPT, as part of our Server Management Services, we regularly help our Customers to perform related Python installation queries.

In this context, we shall look into the installation process of Python 3.10 on Rocky Linux 8.

Main features of Python includes:

• Python can be used on a server to create web applications.
• It can be used alongside software to create workflows.
• It can connect to database systems. It can also read and modify files.
• It can be used to handle big data and perform complex mathematics.
• It can be used for rapid prototyping or production-ready software development.

Steps to install Python 3.10 on Rocky Linux

1. Install dependencies

First, it's prudent that we begin by refreshing the software packages and repositories on Rocky Linux with the below command:

$ sudo dnf update

Once done, install the dependencies including the GCC compiler which will be needed in compiling the source code:

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

2. Download Python 3.10.0 source file

Here, you have to download the Python source code file. To do this, run the following command:

$ wget https://www.python.org/ftp/python/3.10.0/Python-3.10.0.tgz

Once you have downloaded the compressed file, extract it:

$ tar -xvf Python-3.10.0.tgz

3. Install Python 3.10.0 on the system

When the extraction is done, navigate to the uncompressed directory:

$ cd Python-3.10.0

And run the configuration script which performs a checklist to ensure that all the prerequisites are met before the installation begins:

$ ./configure --enable-optimizations

The –enable-optimizations option optimizes the Python binaries by running several tests, although it takes much longer to complete.

To commence the build process, run the make command as follows. Here, the option denotes the -j flag of CPU cores. You can find out the number of CPU cores using the nproc command:

$ nproc

Back to building the source code. Run the make command:

$ make -j 2

Finally, compile the source code by running the following command:

$ sudo make altinstall

Once the compilation is complete, verify the Python version installed with the below command:

$ python3.10 --version

From the output, you will confirm that Python has been successfully installed.
