In this tutorial we will show you how to install and configuration Python 3 on CentOS 7 server. As of the latest CentOS 7, the default Python version still remains python 2.7, and python3 is not available in base repositories. If you need to use python3 as part of Python application dependency, there are several ways to install python3 on CentOS.
This article assumes you have at least basic knowledge of linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo’ to the commands to get root privileges. I will show you through the step by step installation Python on a CentOS 7 server.
Install Python 3 on CentOS 7
Step 1. First let’s start by ensuring your system is up-to-date.
1 2 | yum-yupdate yumgroupinstall"Development tools" |
Step 2. Installing Python.
Method One: Build and Install Python3 from the Source
First thing to do is to go to Python’s download page and download the latest stable version of Python, At the moment of writing this article it is version 3.5.1:
1 | wgethttps://www.python.org/ftp/python/3.5.1/Python-3.5.1.tgz |
Extract source archive and build:
1 2 | tarxzfPython-3.5.1.tgz cdPython-3.5.1 |
Next, we are going to configure the installation directory on /usr/local, We can change the path:
1 | ./configure--prefix=/usr/local |
Building and installing Python through below make altinstall command , this command will replace the python , which is using by the server:
1 | makealtinstall |
You now should be all set to use your newly compiled python version:
1 2 | # python3.5 –V Python3.5.1 |
Method Two: Install Python3 from EPEL Repository
First, you need to enable EPEL repository on your system:
1 | yuminstallepel-release |
Then install python 3.4 and its libraries using yum:
1 | yuminstallpython34 |
Method Three: Install Python3 from Software Collections (SCL)
The first step is to install the utilities needed to manage collections:
1 | yum-yinstallscl-utils |
Once you enable the SCL repository, go ahead and install python3 as follows:
1 | yum-yinstallpython33 |
Python 3.3 will become accessible by launching a new shell instance using the Software Collection scl command:
1 | sclenablepython33bash |
Additional Python libraries and tools, such as pip, can now be installed:
1 | easy_installpip |
Congratulation’s! You have successfully installed Python. Thanks for using this tutorial for installing Python 3 on CentOS 7 system. For additional help or useful information, we recommend you to check the official Python web site.
