redhat所需ks.cfg文件需先在1台redhat系统上生成（yum install system-config-kickstart,然后vnc下执行system-config-kickstart命令）

vi /var/lib/tftpboot/pxelinux.cfg/default

label 3. Install RHEL 6.6 x86_64

kernel RHEL66/vmlinuz
append ks=http://10.0.0.2/ks/ksrhel66.cfg initrd=RHEL66/initrd.img

:wq

cp -rv ksrhel66.cfg /var/www/html/ks/

vi /var/www/html/ks/ksrhel66.cfg （url、时区、selinux调整下，把软件选择部分手动加进来）
