Alhamdullilah - baru dapat pelayan baharu dengan OS CentOS 6.3 untuk pembelajaran dalam talian. Walaupun cuma pelayan maya tetapi spesifikasinya nampaknya lebih tinggi daripada pelayan yang lama dengan OS RHEL5. Mula-mula kena kenalinya dahulu.
Langkah 1: Dapatkan info tentang pelayan, muat turun getinfo.sh daripada laman https://raw.github.com/elrepo/packages/master/getinfo/el6/getinfo.sh
Langkah 2: Laksanakan getinfo.sh dengan:
[root@oll-new home]# chmod +x getinfo.sh
[root@oll-new home]# ./getinfo.sh
No option provided. Defaulting to all information.
Collecting system information for General questions. May take a few minutes.

# This is the default, if you make this bigger yum won't see if the metadata
# is newer on the remote and so you'll "gain" the bandwidth of not having to
# download the new metadata and "pay" for it by yum not having correct
# information.
# It is esp. important, to have correct metadata, for distributions like
# Fedora which don't keep old packages around. If you don't like this checking
# interupting your command line usage, it's much better to have something
# manually check the metadata once an hour (yum-updatesd will do this).
