我看了网上的很多关于PXE教材  自己去适应老出问题
我的配置文件 /etc/dhcpd.conf
ddns-update-style interim;
ignore client-updates;
allow booting ;
allow bootp ;
subnet 192.168.0.0 netmask 255.255.255.0 {
# --- default gateway
      option routers                192.168.0.1;
      option subnet-mask             255.255.255.0;
      option nis-domain             "domain.org";
      option domain-name             "rhel5.com";
      option domain-name-servers    192.168.0.254;
      option time-offset             -18000; # Eastern Standard Time
#    option ntp-servers             192.168.1.1;
#    option netbios-name-servers    192.168.1.1;
# --- Selects point-to-point node (default is hybrid). Don't change this unless
# -- you understand Netbios very well
#    option netbios-node-type 2;
      range dynamic-bootp 192.168.0.100 192.168.0.250;
      default-lease-time 21600;
      max-lease-time 43200;
      next-server 192.168.0.254;
      filename "/pxelinux.0";
      # we want the nameserver to appear at a fixed address
      host ns {
            next-server marvin.redhat.com;
            hardware ethernet 12:34:56:78:AB:CD;
            fixed-address 207.175.42.254;
      }
}
