[Linux] Install Python using Source

Prerequisites

We need to gcc, openssl, bzip, and libffi.

$ sudo yum install gcc openssl-devel bzip2-devel libffi-devel

Download Python

Download Python source from FTP storage via wget.

$ cd /opt
$ sudo wget https://www.python.org/ftp/python/3.x.x/Python-3.x.x.tgz 

Extract the Archive Python File

$ sudo tar xzf Python-3.x.x.tgz

Install Python

$ cd Python-3.x.x
$ sudo ./configure --enable-optimizations
$ sudo make altinstall 

make altinstall prevents replacing the default Python binary in /usr/bin/python.

Check Python Version

Installed Python is located in /usr/local/bin directory.

If you installed Python v3.9.x, you can check its version like this.

$ python3.9 -V

Clean Up

Remove the downloaded source file for cleaning up.

$ sudo rm -f /opt/Python-3.9.6.tgz
