1) 安装DHCP服务器dhcpd
2) 配置/etc/dhcpd.conf文档,下面是此文档的基本内容
max-lease-time -1;
default-lease-time -1; #注:IP地址永但是期
option subnet-mask 255.0.0.0;
option routers 10.0.0.1;
option domain-name-servers 10.10.10.10;
# option netbios-name-servers 10.10.10.10;
option broadcast-address 10.255.255.255;
# option dhcp-class-identifier "PXEClient";
# option vendor-encapsulated-options 01:04:00:00:00:00:ff;
# option option-135 "start";
subnet 10.0.0.0 netmask 255.0.0.0 {
range 10.10.12.131 10.10.12.150;
host blade01 {
hardware ethernet 00:e0:43:00:02:00;
fixed-address 10.10.12.131;
filename "/tftpboot/pxelinux.0"; #注:启动映象文档
}
host blade02 {
hardware ethernet 00:e0:43:00:02:02;
fixed-address 10.10.12.132;
filename "/tftpboot/pxelinux.0";
}
host blade03 {
hardware ethernet 00:e0:43:00:02:04;
fixed-address 10.10.12.133;
filename "/tftpboot/pxelinux.0";
}
host blade04 {
hardware ethernet 00:e0:43:00:02:06;
fixed-address 10.10.12.134;
filename "/tftpboot/pxelinux.0";
}
host blade05 {
hardware ethernet 00:e0:43:00:02:08;
fixed-address 10.10.12.135;
filename "/tftpboot/pxelinux.0";
}
}
说明:dhcp客户得到IP地址后用TFTP协议从服务器上下载启动映象文档。我用syslinux
工具包里边的pxelinux来作为远程启动的loder.
3) 配置tftp server
使用pxelinux作引导工具需要支持TSIZE参数的tftp server。可从http://www.kernel.org/pub/software/network/tftp/下载。
通过xinetd来使用tftp服务，我的/etc/xinetd.conf文档如下
......
service tftp
