Linux operation and maintenance of automated tools Cobbler<\/p>\n
About operating system installation automation, the earlier we use RedHat launched Kickstart to batch install the operating system, in recent years, RedHat has introduced a Cobbler.<\/p>\n
Cobbler development using Python, compact and lightweight, able to complete the installation of the system, and even manage some services. (Known as a tool cobbler can learn)<\/p>\n
Cobbler supports command line management, web interface management, but also provides an API interface to open the second method.<\/p>\n

The following are potential configuration items that you may want to fix:<\/p>\n
1 : service dhcpd is not running
\n2 : debmirror package is not installed, it will be required to manage debian deployments and repositories<\/p>\n
Restart cobblerd and then run ‘cobbler sync’ to apply changes.<\/p>\n
