If your internet connection is behind a web proxy, you need to configure the following on your CentOS server:

System-wide proxy settings – add the following lines to your /etc/environment file:

# vi /etc/environment

http_proxy=”http://proxysrv:8080/”
https_proxy=”https://proxysrv:8080/”
ftp_proxy=”ftp://proxysrv:8080/”
no_proxy=”.mylan.local,.domain1.com,host1,host2″

To apply these settings without restarting the machine run the following commands on the bash shell:

export http_proxy="http://proxysrv:8080/"
export https_proxy="https://proxysrv:8080/"
export ftp_proxy="ftp://proxysrv:8080/"
export no_proxy=".mylan.local,.domain1.com,host1,host2"

You also need to configure yum:

# vi /etc/yum.conf

proxy=http://proxysrv:8080/
