Installation of CentOS 6.x to littledog

Goal: Install centos 6.x, intergrated with the irtf network, allow
      s2 develop code to be compiled and execute (ic, xui, dv, ldog).

Date: 2012/12

Here are notes on the CentOS 6.x installation for littledog

1. General Info

   In 2012/12, the littledog PC was purchased:
   MB/CPU/RAM: Gigabyte B75M-D3H, I3-2120, 8GB RAM, on-board video.
   System purchased by denault on 2012/12 from mwave.com.
	(this 2012/12 system is given to Lockhart for GOCAM, but another
	 system was purchase in 2012/12 as a replacement littledog).

   Boot in rescue mode, and setup hard disk partition using fdisk /dev/hda:
   (or do installation boot do alt+cntl+f2 for shell after GUI starts, cntl-alt-F6 to return).

   Drives are setup as:

      /dev/sda1 - /             40 GB   centos 6.x root
      /dev/sda2 - /r2           40 GB   unused ->
      /dev/sda3 - /r3           40 GB   unused ->
      /dev/sda4 - /aux          rest    free space

2. DVD Install and update

   - install 6.x on via DVD on sda1
     installed bootloader.
     software development workstation installation.
     enabled nis.
	  disable kdump

   - 1st reboot

     Turn off selinux:
        vi /etc/selinux/config
        SELINUX=disabled.
     Turn off filewall:
        sudo system-config-firewall-tui
     reboot

     # disable the network manager.
     service NetworkManager stop
     chkconfig NetworkManager off

     yum update
     reboot

     make droot, mroot

3. General IRTF setup

   /etc/hosts        - add nis servers
   /etc/yp.conf      - configure and enable NIS: system-config-authentication, AND check yp.conf
   /etc/resolv.conf  - add all DNS servers.
   /etc/ntp.conf     - use IRTF NTP servers, and enable ntpd services: system-config-services
                       chkconfig ntpd on

   /etc/auto.master - use yp table
   make links for automounts:
      cd /
      ln -s /netdisks/benchmark
      ln -s /netdisks/hilo_shared
      ln -s /netdisks/irtf.backup
      ln -s /netdisks/scrs1
      ln -s /netdisks/shared
      ln -s /netdisks/starcatalogs2
      ln -s /netdisks/htdocs
      ln -s /netdisks/iarcdata
   /boot/grub/menu.lst  - disable 'hiddenmenu'; remove 'rhgb quiet' vga=788

   Now you should have the IRTF users account and access general IRTF shared disks.
