yum through proxy

1) You can set the environment variable, http_proxy and ftp_proxy, each time before you start yum as

export http_proxy="http://ip:port"
export ftp_proxy="http://ip:port"

For corporate environment, you likely need the uesrname and password as well as:
export http_proxy="http://username:password@ip:port"
export ftp_proxy="http://username:password@ip:port"

or

2) Update the /etc/yum.conf add the following line under
proxy=http://ip:port/

Make sure you include the last slat(/)

It saves you from setting the environment variable every time, but having you plain password store in a file may not be a good idea
