Network install point httpd with Centos or RHEL6 using kickstart

Why set up a network install point? So you can do consistent Linux installations. Really so you can do the same installation over and over again and come out with consistent results. Today’s article is how to set up the install point and have it work. There is credit for the source article below but by itself that article will not work for Centos 6.

The chosen install path is /var/www/html/centos/6.2

When it is released Centos 6.3 will go in a directory named 6.3

My source iso images are in a bootable partition, not an lvm mount called /iso

Partial ll listing:

-rw-r–r–. 1 root   root   4423129088 Dec 15 20:50 CentOS-6.2-x86_64-bin-DVD1.iso
-rw-r–r–. 1 root   root   1317967872 Dec 15 20:50 CentOS-6.2-x86_64-bin-DVD2.iso

 

mount -o loop /iso/CentOS-6.2-x86_64-bin-DVD1.iso /mnt
# The file name does not matter a bit. Just use the one you have downloaded.
# Make sure nothing is already mounted on /mnt folder

Copy the install point to your target directory.

cp -rvf /mnt/* /var/www/html/centos/6.2

This will miss two files, .discinfo and .treeinfo which kickstart needs to work right.

cp /mnt/.discinfo /var/www/html/centos/6.2 
cp /mnt/.treeinfo /var/www/html/centos/6.2 What the install depot should look like:
 umount and repeat for DVD2 ls -lart /var/www/html/centos/6.2

Output:
[root@solaria 6.2]# ls -lart /var/www/html/centos/6.2

for the install from kickstart to work, you will need to update the repodata and create the group information to avoid some nasty install issues that will frustrate you a lot.
 cd /var/www/html/centos/6.2

 

createrepo -u -g /var/www/html/centos/6.2/repodata/

Output

[root@solaria 6.2]# createrepo -u -g /var/www/html/centos/6.2/repodata/

  1. Thank you for the acknowledgement (re the source material). I am a bit confused, though, about the part where you say that, by itself, my article won’t work with Centos 6, because I use the techniques that article describes to perform, regularly, Centos & Scientific Linux 5.x and Centos & Scientific Linux 6.x installs… and I’ve never once had to fiddle .discinfo or .treeinfo, nor have I ever had a subsequent kickstart installation fail. Would be interested to know the specifics of ‘it won’t work’, if you have the time…
