PXE自动装机脚本提纲
PXE脚本分成四个模块来写。
一、DHCP内容
DHCP Server Configuration file.
see /usr/share/doc/dhcp*/dhcpd.conf.example
see dhcpd.conf(5) man page
subnet 192.168.4.0 netmask 255.255.255.0 {
range 192.168.4.100 192.168.4.200;
option domain-name-servers 192.168.4.7;
option routers 192.168.4.254;
default-lease-time 600;
max-lease-time 7200;
next-server 192.168.4.7;
filename “pxelinux.0”;
}

三、界面代码
default vesamenu.c32
timeout 600
display boot.msg
Clear the screen when exiting the menu, instead of leaving the menu displayed.
For vesamenu, this means the graphical background is still displayed without
the menu itself for as long as the screen remains in graphics mode.
