above URL is a guide to configure & setup the cluster in win2008. As we known, all the winserver punya configuration is GUI. So it was really easy for you to configure this..

Keep your linux box up to date

Gua noticed yang default version of yum-updatesd does not function reliably. So gua cari better solution to make sure centos box gua updated. So untuk memastikan server gua always on up to date gua lebih prefer guna kan cron.. Steps seperti berikut:-

1. Disable yum-updatesd:-

/sbin/chkconfig yum-updatesd off

2. Create yum.cron and make it executeble dan letakkan dia di folder /etc/cron.daily ataupun /etc/cron.weekly. Didalam file yum.cron itu masukan line seperti berikut:-

#!/bin/sh
/usr/bin/yum -R 120 -e 0 -d 0 -y update yum
/usr/bin/yum -R 10 -e -0 -d 0 -y update
