How do I fix this problem? How can I install wget on a CentOS/RHEL version 8, 7 or 6 server using yum command?

GNU Wget is a free and open source software package for retrieving files using HTTP, HTTPS, and FTP, the most widely-used Internet protocols. The GNU/wget might not be installed on your system and here is how to install it using yum command.

To use the wget with proxy authentication, enter:
$ export https_proxy="https://server1.cyberciti.biz:3128/"
$ wget --proxy-user "USERNameHere" --proxy-password "PASSWORDHere" http://url-here

To use wget with a username and password for FTP / HTTP file retrieval, use:
$ wget --user=NAME --password='PASSWORD' url
To download a large file in size in background, enter:
$ wget -bqc http://path-to-freebsd-mirros-url/freebsd-lastest.iso
You can resume broken download with wget using the following syntax:
$ wget -c http://url/large.file.tar.gz
$ wget --continue https://url/file.iso

Anther usage is to archive a website using wget:
$ wget -nprk 'https://www.some-url-here/'

Creating ~/.wgetrc file

The $HOME/.wgetrc file act as an initialization file for GNU wget. You can store option in it. Here is my sample $HOME/.wgetrc file:

# sample file 
# Try ipv6 addresses first
prefer-family = IPv6
 
# Setup proxy
https_proxy = http://server1.cyberciti.biz:3128/
http_proxy = http://server1.cyberciti.biz:3128/
ftp_proxy = http://server1.cyberciti.biz:3128/
 
# Setup the credentials for both http/ftp
user=vivek
password=OhMyCoolPasswordHere
