配置DHCP服务

[root@kickstart ~]# cd /etc/dhcp/
[root@kickstart dhcp]# ls
dhclient.ddhclient-exit-hooks.ddhcpd6.confdhcpd.confscripts
[root@kickstart dhcp]# cat dhcpd.conf
#
# DHCP Server Configuration file.
#see /usr/share/doc/dhcp*/dhcpd.conf.example
#see dhcpd.conf(5) man page
#
[root@kickstart dhcp]# mv dhcpd.conf dhcpd.conf0622
[root@kickstart dhcp]# cp /usr/share/doc/dhcp-4.2.5/dhcpd.conf.example dhcpd.conf
[root@kickstart dhcp]# ll

drwxr-x---2 root dhcpd28 Jun 22 10:51 scripts

在dhcpd.conf增加如下配置

subnet 192.168.20.0 netmask 255.255.255.0 {
range 192.168.20.101 192.168.20.200;
option domain-name-servers ns1.internal.example.org;
option domain-name "internal.example.org";
option routers 192.168.20.254;
option broadcast-address 192.168.20.255;
default-lease-time 600;
max-lease-time 7200;
next-server 192.168.20.100;
filename "pxelinux.0";
}

开启服务，并设为开机自动启动；

[root@kickstart ~]# cd /etc/dhcp/
[root@kickstart dhcp]# ls
