1、源程序下载地址是：ftp://ftp.isc.org/isc/dhcp/dhcp-3.0.tar.gz ，我们的版本是：dhcpd-3.0
2、复制到：/usr/local/scr后解压：tar zxvf dhcp-3.0.tar.gz
3、cd /usr/local/src/dhcp-3.0.tar.gz
4、./configure
5、make(如果不是第一次编译，先make clean)

7、cp ./server/dhcpd.conf /etc

# dhcpd.conf # # Sample configuration file for ISC dhcpd # # option definitions common to all supported networks... option domain-name "rd.xxx.com"; option domain-name-servers compaq.rd.xxx.com; default-lease-time 86400; max-lease-time 172800; ddns-update-style ad-hoc; # If this DHCP server is the official DHCP server for the local # network, the authoritative directive should be uncommented. #authoritative; # Use this to send dhcp log messages to a different log file (you also # have to hack syslog.conf to complete the redirection). log-facility local7; # No service will be given on this subnet, but declaring it helps the # DHCP server to understand the network topology. # This is a very basic subnet declaration. subnet 21.9.22.0 netmask 255.255.255.224 { range 21.9.22.2 21.9.22.6; option routers 21.9.22.1; } # This declaration allows BOOTP clients to get dynamic addresses, # which we don't really recommend. #subnet 10.254.239.32 netmask 255.255.255.224 { # range dynamic-bootp 10.254.239.40 10.254.239.60; # option broadcast-address 10.254.239.31; # option routers rtr-239-32-1.example.org; #} # A slightly different configuration for an internal subnet. #subnet 10.5.5.0 netmask 255.255.255.224 { # range 10.5.5.26 10.5.5.30; # option domain-name-servers ns1.internal.example.org; # option domain-name "internal.example.org"; # option routers 10.5.5.1; # option broadcast-address 10.5.5.31; # default-lease-time 600; # max-lease-time 7200; #} # Hosts which require special configuration options can be listed in # host statements. If no address is specified, the address will be # allocated dynamically (if possible), but the host-specific information # will still come from the host declaration. #host passacaglia { # hardware ethernet 0:0:c0:5d:bd:95; # filename "vmunix.passacaglia"; # server-name "toccata.fugue.com"; #} # Fixed IP addresses can also be specified for hosts. These addresses # should not also be listed as being available for dynamic assignment. # Hosts for which fixed IP addresses have been specified can boot using # BOOTP or DHCP.

The example below shows a case where all clients # in a certain class get addresses on the 10.17.224/24 subnet, and all # other clients get addresses on the 10.0.29/24 subnet. #class "foo" { # match if substring (option vendor-class-identifier, 0, 4) = "SUNW"; #} #shared-network 224-29 { # subnet 10.17.224.0 netmask 255.255.255.0 { # option routers rtr-224.example.org; # } # subnet 10.0.29.0 netmask 255.255.255.0 { # option routers rtr-29.example.org; # } # pool { # allow members of "foo"; # range 10.17.224.10 10.17.224.250; # } # pool { # deny members of "foo"; # range 10.0.29.10 10.0.29.230; # }上面这个文件中后面都是注释，是原来系统给你的配置做的例子，可以不要。当然除非你用到它们，并
