Kickstart unattended Installation

1 mount the system files you need to install to/mnt first:

# mount-t cifs-o username=administrator,passwd=abcde//192.168.1.99/iso/mnt/

2 1-1 into the mounted/mnt directory, RPM installation Dhcp,tftp,kickstart:

#rpm-IVH *kickstart*

#rpm-IVH xinetd-2.3.14-10.el5.i386.rpm (TFTP service)

#rpm-IVH dhcp-3.0.5-23.el5.i386.rpm

RPM dhcp-devel-3.0.5-23.el5.i386.rpm

1-2 configuration dhcpd:

# cp/usr/share/doc/dhcp-3.0.5/dhcpd.conf.sample/etc/dhcpd.conf

# vi/etc/dhcpd.conf

We will open the defined Ks.cfg file via HTTP access, so we need to install httpd (the installation httpd step over)
