SystemImager

Getting the required files

• A script that grabs the required components: http://compbio.chemistry.uq.edu.au/mediawiki/upload/b/ba/Install.txt
  • Download and place in systemimager dir

mkdir systemimager
cd systemimager
wget http://compbio.chemistry.uq.edu.au/mediawiki/upload/b/ba/Install.txt
mv Install.txt Install.pl
chmod +x Install.pl

• Now we use the installer to grab the required packages:
  • systemimager
  • systemimager-bittorrent
  • systemimager-client
  • systemimager-common
  • systemimager-flamethrower
  • systemimager-server
  • systemimager-x86_64boot-standard
  • systemimager-x86_64initrd_template

./Install.pl -v --download-only --tag stable --directory . systemconfigurator systemimager-client \
 systemimager-common systemimager-x86_64boot-standard systemimager-x86_64initrd_template systemimager-server \ 
 systemimager-bittorrent systemimager-flamethrower

Setup the imaging server

• First off, I installed some files that may be required later (if not these can be removed):

yum install tftpd
yum install tftp* (xinetd dependency which is required will be grabbed)
NOTE: These packages are also suggested: pxe dhcp-server dhcp

• Transfer the required files to guava

scp systemconfigurator-* systemimager-common-* systemimager-server-* systemimager-x86_64boot-standard-* \
systemimager-bittorrent-* username@guava:/working/dir

• Install the packages on guava

rpm -ivh systemconfigurator-* (yum install perl-AppConfig to satify dependency)
rpm -ivh systemimager-common-* systemimager-server-* systemimager-x86_64boot-standard-*
(yum install  perl-XML-Simple to satisfy dependency)
rpm -ivh systemimager-bittorrent-*

• Setup the directory structure

mkdir /other/systemimages(images, overrides, tarballs, torrents)

• Edit the config file

cd /etc/systemimager
cp systemimager.conf systemimager.conf.BAK
vi systemimager.conf -- Change to reflect the directory structure created above

Setup the golden client

• OPEN: 873 TCP (not sure if this is required on the image-server)

• Install the required packages

rpm -ivh systemconfigurator-* (yum install perl-AppConfig)
rpm -ivh systemimager-common-* systemimager-client-* systemimager-x86_64initrd_template-*

• These files need to be possibly edited:

client.conf
updateclient.local.exclude -- THIS DEFINATELY: To avoid nfs shared etc.

Prepare an image of the golden client

NOTE: The si_* tools are placed in:

• /usr/sbin/si_prepareclient
• /usr/sbin/si_updateclient

PREPARE AN IMAGE

• On the golden client:

/usr/sbin/si_prepareclient --server 152.98.195.189

Getting the image of the golden client to the image server

• On the image server

/usr/sbin/si_getimage -golden-client 152.98.195.136 -image my_golden_client -ip-assignment static

Setting up the image server to serve images (BOOTSERVER)

OPEN: 873 TCP (not sure if this is required on the image-server)

• Start xinetd: NOTE: USE CHKCONFIG TO START ALWAYS

/sbin/service xinetd start

• Start the image server daemon:

/etc/init.d/systemimager-server-rsyncd start

• Configure the boot server

/usr/sbin/si_mkbootserver 

NOTE:

• This script may modify the following files:
  • /etc/services
  • /etc/inetd.conf
  • /etc/xinetd.d/tftp

UPLOAD AN IMAGE TO THE IMAGE SERVER

• On the golden client

si_getimage --golden-client uqmd05 --image my_image --exclude '/media/*' --exclude '/lib/klibc/events/*'
