connect yum using proxy, yum cannot connect through proxy

Yum can connect with external repository if http_proxy , ftp_proxy environment variables are set properly.

Set the environment variables (from command line):

# http_proxy="http://192.168.1.1:3128"
# ftp_proxy="http://192.168.1.1:3128"

/* if PROXY host is http://192.168.1.1/ & PROT is 3128 */
Export the variable (from command line):

# export http_proxyexport ftp_proxy

Test yum & reply me.
