How To Install perl-CGI on CentOS 8

perl-CGI is Handle Common Gateway Interface requests and responses

Introduction

In this tutorial we learn how to install perl-CGI on CentOS 8.

What is `perl-CGI`

CGI.pm is a stable, complete and mature solution for processing and preparing HTTP requests and responses. Major features including processing form submissions, file uploads, reading and writing cookies, query string generation and manipulation, and processing and preparing HTTP headers. Some HTML generation utilities are included as well. CGI.pm performs very well in in a vanilla CGI.pm environment and also comes with built-in support for mod_perl and mod_perl2 as well as FastCGI.

We can use yum or dnf to install perl-CGI on CentOS 8. In this tutorial we discuss both methods but you only need to choose one of method to install perl-CGI.

Install perl-CGI on CentOS 8 Using dnf

Update yum database with dnf using the following command.

sudo dnf makecache --refresh
