In this tutorial, we will show you how to install and configuration of Pip on a CentOS 7. For those of you who didn’t know, A pip command is a tool for installing and managing Python packages, such as those found in the Python Package Index. With the help of pip, you can also install the package of a particular version. Most importantly pip has a feature to manage full lists of packages and corresponding version numbers, possibly through a “requirements” file. It performs the same basic job as easy_install, but with some extra features.
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 the step-by-step installation of Pip Python on a CentOS 7 server.
Prerequisites
- A server running one of the following operating systems: CentOS 7.
- It’s recommended that you use a fresh OS install to prevent any potential issues.
- SSH access to the server (or just open Terminal if you’re on a desktop).
- A
non-root sudo useror access to theroot user. We recommend acting as anon-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.
