Python3 Installation and Package Management Summary

This summary provides a step-by-step guide on how to install Python3 and related package management tools using a CentOS Linux distribution.

1. Install Python3 Dependencies

Begin by installing the necessary dependencies for Python3 using the YUM package manager. If you are not logged in as a root user, prepend the command with sudo.

sudo yum -y 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

2. Download Python3 Source Code

Download the Python3 source code using wget from the Taobao mirror to increase download speed.

wget http://npm.taobao.org/mirrors/python/3.7.5/Python-3.7.5.tar.xz

3. Compile Python3 Source Code

Extract the downloaded source code archive and compile Python3 by executing the configuration and installation commands.

xz -d Python-3.7.5.tar.xz
tar -xf Python-3.7.5.tar
cd Python-3.7.5
./configure prefix=/usr/local/python3
make && make install

4. Create Python3 Symlink

Create a symlink to make Python3 accessible system-wide and verify the installation.

ln -s /usr/local/python3/bin/python3.7 /usr/bin/python3
python3 -V

5. Install Setuptools

Setuptools is a collection of enhancements to the Python distutils that allows you to more easily build and distribute Python packages. Download, extract, and install setuptools using Python3.

wget --no-check-certificate https://pypi.python.org/packages/source/s/setuptools/setuptools-19.6.tar.gz
tar -zxvf setuptools-19.6.tar.gz
cd setuptools-19.6
python3 setup.py build
python3 setup.py install

6. Install pip3

pip is a package management system used to install and manage software packages written in Python. Download, extract, and install pip3, then create symlinks for easy access.

wget --no-check-certificate https://pypi.python.org/packages/source/p/pip/pip-8.0.2.tar.gz
tar -zxvf pip-8.0.2.tar.gz
cd pip-8.0.2
python3 setup.py build
python3 setup.py install
ln -s /usr/local/python3/bin/pip /usr/bin/pip
ln -s /usr/local/python3/bin/pip3 /usr/bin/pip3
pip3 -V
pip3 install --upgrade pip

7. Install podman-compose

podman-compose is a tool based on Python and can be installed using pip. Post-installation, update the PATH environment variable and verify the installation of podman-compose.

pip3 install podman-compose
vi /etc/profile # Add /usr/local/python3/bin to PATH
export PATH=$PATH:/usr/local/python3/bin
python3 -m pip install --upgrade pip
podman-compose version
