Why install these packages?
The packages mentioned above are crucial for different aspects of Python. For example, openssl-devel provides support for secure socket layer (SSL) encryption, bzip2-devel enables the use of bzip2 compression, and zlib-devel allows for compressed data manipulation. The other packages are also essential for various functionalities and features of Python.
By installing these prerequisites, you ensure that Python has all the necessary components to run smoothly on your AlmaLinux 9 system. Once these packages are installed, you can proceed to the next step and download the Python source code for installation.
Step 3: Download and Install Python
Now that you have prepared your AlmaLinux 9 system and installed the necessary prerequisites, it's time to download and install Python. Follow the steps below to complete the installation process:
- First, use the
wgetcommand to download the source code of the latest Python version. You can find the download link on the official Python website. - Once the download is complete, use the
tarcommand to extract the downloaded file. This will create a new folder with the Python source code. - Navigate to the Python installation folder by using the
cdcommand followed by the folder name. - Now, it's time to configure the installation. Use the
./configurecommand to prepare the installation and configure it according to your system's specifications. - After the configuration is complete, run the
makecommand. This will compile the Python source code and create the necessary binaries. - Finally, use the
make installcommand to install Python on your AlmaLinux 9 system. This will copy the compiled files to the appropriate directories and set up the necessary symlinks.
