2.Configuring Proxy Server Access
To enable all yum operations to use a proxy server, specify the proxy server details in /etc/yum.conf. The proxy setting must specify the proxy server as a complete URL, including the TCP port number. If your proxy server requires a username and password, specify these by adding proxy_username and proxy_password settings.

proxy=http://URL:PORT
# The account details for yum connections(optional)
proxy_username=YOUR-PROXY-USERNAME
