#Power on the system, and you will see a BIOS message about the '''HP Smart Array 6i Controller'''. Press the ''F8'' key, to go into the '''Option Rom Configuration for Arrays''' screen.
#Under the '''Main Menu''', select '''Delete Logical Drive''', and then on the next screen, press F8 to delete the pre-configured RAID 1+0 Drive.
#At the '''Warning''' screen, press the ''F3'' key. When you receive the prompt to press ''Enter'' to continue, press the ''Enter'' key.
#Under the '''Main Menu''', select '''Create Logical Drive''',
#At the next screen, all drives should be selected, and under '''Raid Configurations''' the '''RAID 1+0''' level should be selected. Press ''Enter'' to continue.
#You will receive a confirmation prompt, summarizing the information about your logical drive. Press ''F8''.
#At the '''Configuration saved prompt, press ''Enter''.
#When you see the '''Main Menu''' screen again, you may press ''Esc''.

== Method 1 - Standard hardware w/Kickstart ==

This is the recomended, and easiest installation method to try first.

=== Get the installation media that you need ===

Simply obtain the correct boot ISO images from either http://bfs.iplink.net/cos/ or http://bfs.int.iplink.net/cos/ (this one is if you are inside the Interlink office). You will want to grab the ones for the most recent supported version of CentOS (at the time of writing, this was 4.4). Here's an example of some of the different boot ISO's available:

; CentOS-4.4-i386-boot-custom-ide-raid-two-master.iso : The system must be configured with two master IDE drives (a primary master [hda] and a secondary master [hdc]) that are identical.
; CentOS-4.4-i386-boot-custom-ide-single-master.iso : The system must be configured with at least one IDE drive configured to be the primary master (hda), and no RAID is configured.
; CentOS-4.4-i386-boot-custom-scsi-raid-two-hd.iso : The system must be configured with two SCSI drives that show up before any other SCSI storage devices on the system (sda and sdb). Keep in mind that properly configured '''SATA''' drives will look like SCSI drives to the system, so you will want to use this if you have SATA enabled in the BIOS. The drives should be identical.
; CentOS-4.4-i386-boot-custom-scsi-single-hd.iso : The system must be configuraed with at least one SCSI drive configured to be the first SCSI storage device that shows up on the system. Keep in mind that properly configured '''SATA''' drives will look like SCSI drives to the system, so you will want to use this if you have SATA enabled in the BIOS.
; CentOS-4.4-i386-boot-custom-hp-dl380-cnt44.iso : This is custom for the HP ProLiant DL380 server configured with two RAID 1+0 SCSI disks.

All of these kickstarts expect that you are installing with CD images of the OS, because so many times it is not possible to get a good connection for a network installation. We do have a network install kickstart available on request. Thus, you will also need to download the four OS CD's that are on the site. (You may also want to grab the latest ISO from http://bfs.iplink.net/cos/iso or http://bfs.int.iplink.net/cos/iso for the add on software now too.)

{{NOTE|Sometimes from outside, the http://bfs.iplink.net/cos site will try to redirect itself to http://bfs.int.iplink.net/cos/ in your browser, so that after you log in you get an error message about not being able to find the site. Just re enter the http://bfs.iplink.net/cos site in your browser, and it should be okay.}}

=== Start the installation ===

Boot off of the boot CD that you downloaded (not the CentOS CD1, but the one customized for your system's hardware config.) If all goes well, it will load up, and then give you an error about not being able to find the installation disc. At this point, insert the CentOS CD1 and hit Enter, and the kickstart should do the rest. You will be prompted to insert various CD's by the installer as the installation finishes.

==== If there are problems ====

If you get errors, you can try a couple things:

* Check that your drives have their jumpers set correctly and showing up in the right order in the BIOS
* Try a different boot CD (maybe one without RAID).
* Try a more manual partitioning approach, such as in Method 2 or Method 3

== Method 2 - Kickstart for package and network configuration, but manual partitioning ==

Most problems tend to be because the partitioning doesn't work for one reason or another. We have now made available a boot CD that does all of the work for you, but makes you partition the system yourself, to help you work around issues with problematic hardware.

Simply obtain the cc-simple ISO image from either http://bfs.iplink.net/cos/ or http://bfs.int.iplink.net/cos/ (this one is if you are inside the Interlink office). You will want to grab the ones for the most recent supported version of CentOS (at the time of writing, this was 4.2). The current image is:

; CentOS-4.4-i386-boot-custom-cc-simple.iso : You must manually partition the system, but everything else is done for you!

This kickstart expects that you are installing with CD images of the OS, because so many times it is not possible to get a good connection for a network installation. We do have a network install kickstart available on request. Thus, you will also need to download the four OS CD's that are on the site.

cat /etc/inittab.backup | /bin/sed 's/5:initdefault/3:initdefault/g' > /etc/inittab
reboot
</bash>

The server will reboot after this, and should come up to a text based login.

= Installation of Add-On software =

After installing the operating system, you must now install the add-on '''cc-systems-centos4-software''' CDs. To do so:

Insert the CD1 into the CDROM drive of the server and type the following commands as the root user:

mount /media/cdrecorder
# if for some reason that fails, try /media/cdrom
cd /media/cdrecorder
sh install.sh

Insert the CD2 into the CDROM drive of the server and type the following commands as the root user:

mount /media/cdrecorder
# if for some reason that fails, try /media/cdrom
cd /media/cdrecorder
sh install.sh

= FAQ for CentOS 4.x Software Versions =

== Q: Problems with LTSP ==

If you are having problems with LTSP within your own network (you are not using the default 10.10.10.0/24 network), make sure that the 10.10.10 addresses have been changed in all the appropriate places:

* /etc/hosts
* /etc/sysconfig/network
* /etc/sysconfig/netowrk-scripts/*
* /exports/
* /opt/ltsp/i386/etc/lts.conf
* /etc/dhcpd.conf

You may also need to insure the NFS has been started on the server. Insure the services:

* nfs
* nfslock
* portmap

Have been started.

== Q: Can we disable kernel warnings on the screen? ==

A: You might get warnings that interrupt work even when there doesn't seem to be a problem. For example:

hdd:irq timeout: status=0Xd0 (Busy)
ide: failed opcode was: unknown
hdd: ATAPI reset complete

You can disable those messages popping up on the console, so that they don't continue to interfere with server use by editing the file '''/etc/sysconfig/syslog''' and modifying the KLOGD_OPTIONS line to look like this:

<bash>
# KLOGD_OPTIONS="-x"
KLOGD_OPTIONS="-2 -c 1"
</bash>

Then type:

service syslog restart

== A: How do I enable DHCP on the server? ==
A: On a newly installed server, the DHCP service does not run by default, because it can cause problems on networks that already have DHCP running. To enable it:

chkconfig dhcpd on
service dhcpd restart

== Q: How do I enable the diskless workstation software on the server? ==
A: On a newly installed server, the following commands should be run as root:

chkconfig tftp on
chkconfig xinetd on
chkconfig dhcpd on
service dhcpd restart
service xinetd restart

== Q: I am missing NCFTP, how can I install it? ==
A: Newer versions of the 4.1 software should have ncftp installed, however some of the earlier versions may now. If the server that needs it is connected to the network, running the command:

yum install ncftp

Should install it for you.

The RPM can also be downloaded from one of the following sites:

* (Externally available) http://bfs.iplink.net/yum/centos-cc/4/cc/ncftp-3.1.8-3.el4.i386.rpm
* (Internal to Interlink) http://bfs.int.iplink.net/yum/centos-cc/4/cc/ncftp-3.1.8-3.el4.i386.rpm
* http://heinous.org/files/rpms/ncftp-3.1.8-3.el4.i386.rpm

Once the RPM is on the server, install it with:

rpm -Uvh ncftp-3.1.8-3.el4.i386.rpm

; Note : It is recommended to start using wget or lftp instead of ncftp, as it is out of date software. See http://heinous.org/wiki/FTP_Clients for a comparison of the old ncftpget command to the newer lftp syntax. See http://heinous.org/wiki/Wget_examples for examples of ways to use wget with ftp servers.

== Q: When connecting to the Labzilla program (opti) with Teraterm from Windows, the backspace key does not work properly. How can I fix that? ==

* Start the connection by clicking on the icon that you normally would, but do not log in yet.
* In the top left corner of the Teraterm application screen, click on the icon of a computer and select '''Show menu bar'''
* Select '''Setup''', and then select '''Keyboard'''.
* Make sure both of the transmit del by boxes are checked like so:

[[Image:tterm_kbd_setup.png]]

* Select OK
* Select '''Setup''', and then select '''Save setup'''
* The filename should be teraterm.ini and the directory should be where teraterm is installed on your system.
* Select '''Save'''

The backspace key should now work correctly in the Labzilla application.
