SA is now aware of the importance of operational automation, especially for companies that increase in number of servers by hundreds of and thousands of, and simply install the system, if not done through automation, is unthinkable.

Operation and maintenance automation installation, the early general use of manual configuration Pxe+dhcp+tftp with Kickstart, now open-source tools, such as COBBLER,OPENQRM and spacewalk. This article focuses on cobbler.

Cobbler is a fast network-installed Linux service and can be adjusted to support network installation of Windows. The tool uses Python development, small and lightweight (15k line code only), with simple commands to complete the configuration of the PXE network installation environment, while also managing Dhcp,dns, and Yum package mirroring.

Cobbler Support Command line management, web interface management, also provides API interface, can be easily used two times development.
