How do I set up the local yum repo?

You may now get your CentOS installs and updates locally on Limestone's network. When routed correctly, it will not count against your monthly bandwidth.

Yum Configuration

Edit the config:

vi /etc/yum.repos.d/CentOS-Base.repo

And put the following:

[base]
name=CentOS-$releasever - Base
baseurl=http://centos.mirror.cust.lstn.net/$releasever/os/$basearch/
gpgcheck=1
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5

[update]
name=CentOS-$releasever - Updates
baseurl=http://centos.mirror.cust.lstn.net/$releasever/updates/$basearch/
gpgcheck=1
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5

[addons]
name=CentOS-$releasever - Addons
baseurl=http://centos.mirror.cust.lstn.net/$releasever/addons/$basearch/
gpgcheck=1
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5

[extras]
name=CentOS-$releasever - Extras
baseurl=http://centos.mirror.cust.lstn.net/$releasever/extras/$basearch/
gpgcheck=1
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5

[centosplus]
name=CentOS-$releasever - Plus
baseurl=http://centos.mirror.cust.lstn.net/$releasever/centosplus/$basearch/
gpgcheck=1
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5

Correctly Route the Traffic :

ip route add 10.0.0.0/8 via <private-gateway-ip> dev <private-interface>

If you want this to save after reboot, add to /etc/sysconfig/network-scripts/route-private-device :

10.0.0.0/8 dev <strong>private-interface</strong>

Example:

10.0.0.0/8 dev eth1
