Automating the configuration of Kickstart servers

The last article just completed the automatic installation of Nagios, this article continues, think of the previous days manually configured kickstart server process is more cumbersome, the idea is not clear, or the installation configuration process to write into the script is very convenient, feeling is once and for all, reduce the follow-up work of the Labor, And the whole idea process is clearer.

Experimental environment: centos6.3 x86_64

Firewall closed, SELinux set to Disabled

Note: The virtual machine needs to first load the centos6.3 x86_64 installation image ISO

The MAC address in the script needs to be changed to the MAC address of your current machine

Ks.cfg configuration file about setting the client password needs to be set yourself

You can start the installation configuration kickstart by executing the script directly.
