====== NSM install @ CentOS ======

===== Install procedure =====
  - Install CentOS 5.3
    - Download CentOS install ISO from http://vault.centos.org/5.3/isos/i386/CentOS-5.3-i386-bin-1of6.iso
    - Please follow these criteria(its IMPORTANT): 5.3 & i386 & disk1
    - Install with minimum CentOS (do not select any service and application).
  - Temporary disable iptables Firewall
    - #service iptables stop
    - #chkconfig --level 12345 iptables off
  - Edit /etc/yum.repos.d/CentOS-Base.repo 照下面的改吧，其他都是照樣照句。會改這個是因為 5.3 已經 EOL 了，所以得用 vault.centos.org 抓套件<code>
name=CentOS-5.3 - Base
baseurl=http://vault.centos.org/5.3/os/$basearch/
</code>
  - Backup /etc/redhat-release, Change content from "CentOS release 5.3 (Final)" to "Red Hat Enterprise Linux Server release 5"
