Ubuntu Linux系统配置PXE网络安装环境，首先要配置的就是dhcp服务，我们需要先安装dhcp服务端，apt-get install isc-dhcp-server。然后修改配置文件sudo gedit /etc/dhcp/dhcpd.conf
subnet 172.16.45.0 netmask 255.255.255.0 {
range 172.16.45.150 172.16.45.250;
option domain-name-servers ns1.internal.example.org;
option domain-name "internal.example.org";
option routers 172.16.45.254;
option broadcast-address 172.16.45.255;
next-server 172.16.45.129;
default-lease-time 600;
max-lease-time 7200;
filename "pxelinux.0";
}
然后启动dhcp服务即可，sudo /etc/init.d/isc-dhcp-server start
