Common orders

cobbler check checks cobbler configuration
 The cobbler list lists all the cobbler elements
 cobbler report lists the details of the elements
 cobbler distro to view imported distribution system information
 cobbler system Views Additional System Information
 cobbler profile view configuration information
 cobbler sync synchronizes Cobbler configuration, and changes to configuration are best performed
 cobbler reposync synchronous yum repository

Configuration files

/ etc/cobbler/settings Cobbler master configuration file
 / etc/cobbler/users.digest User Name Password Profile for web Access
 / etc/cobbler/users.conf Cobbler WebUI/Web Services Authorization Profile
 / etc/cobbler/modules.conf module configuration file
 / etc/cobbler/iso/Buildiso Template Profile
 / etc/cobbler/power power power configuration file
 / etc/cobbler/pxe Pxeprofile configuration template
 / etc/cobbler contains rsync, dhcp, dns, pxe and other service templates

3. Practical operation
Modify the pxe boot interface file / var/lib/tftpboot/pxelinux.cfg/default;
Ignore the name of the network card that comes with the system, and specify the name of the network card according to the requirement.
vim /etc/cobbler/pxe/pxeprofile.template

 LABEL $profile_name
        kernel $kernel_path
        $menu_label
        $append_line initrd=initrd.img net.ifnames=0 biosdevname=0
        ipappend 2

IV. System Mirror Data Catalogue
repos mirrors and kickstart files are placed in the / var/www/cobbler directory to ensure that the / var directory has enough space to store these files.

/ var/www/cobbler/images/distribution Kernel and initrd images for remote network startup
 / var/www/cobbler/ks_mirror/Store imported distribution system data
 / var/www/cobbler/repo_mirror/yum warehouse storage directory
 / var/log/cobbler Cobbler log file cobbler.log install.log 

V. Cobbler Data Catalogue
/ var/lib/cobbler directory storage and configuration related to Cobler profiles, systems, distros.

/ var/lib/cobbler/config/Deposit distros, repos, systems, profiles and other configurations
 / var/lib/cobbler/snippets/small script fragments that can be imported from the storage ks file are worth studying.
/ var/lib/cobbler/triggers stores user-defined cobbler commands
 / var/lib/cobbler/kickstart/store kickstart configuration file

VI. Log files
