[CentOS-mirror] Yum update from local mirror server

[Mohamed Talaat]

Hello,

We have a centos mirror server connected to our network.

We would like to use this mirror server to do (yum update) instead of using
default yum servers to save bandwidth and faster updates


Please let me know step by step how to configure my servers to use
http://mirror.citynethost.com/centos/ for yum update

Regards
