Start Cobbler not updating dhcpd conf

Cobbler not updating dhcpd conf

Things has been expained pretty well in detailed fashion.

Once you have that mac address, you can create a system in cobbler that associates the mac address with a profile, and allows you to assign network and hostname settings, etc.

The new system’s username/password is the same as we set in the cobbler configuration file.

Change the default password via: # rsync -a '/mnt1/' /var/www/cobbler/ks_mirror/Cent OS-6.6-x86_64/ --exclude-from=/etc/cobbler/rsync.exclude --progress # COMPSXML=$(ls /var/www/cobbler/ks_mirror/Cent OS-6.6-x86_64/repodata/*comps*.xml) # createrepo -c cache -s sha --update --groupfile $ /var/www/cobbler/ks_mirror/Cent OS-6.6-x86_64 Verify it via installing a new machine running Cent OS6.6. Trouble shooting for controlling the Systems(which is the node information which added into cobbler system).

Enable tftp and rsync in xinetd We want to make sure tftp and rsync are enabled otherwise pxeboot will not work properly.

Edit the /etc/xinetd.d/tftp and /etc/xinetd.d/rsync files and change disable = yes to disable = no.

[[email protected] Server ~]# cobbler check The following are potential configuration items that you may want to fix: 1 : dhcpd is not installed 2 : some network boot-loaders are missing from /var/lib/cobbler/loaders, you may run 'cobbler get-loaders' to download them, or, if you only want to handle x86/x86_64 netbooting, you may ensure that you have installed a *recent* version of the syslinux package installed and can ignore this message entirely.
