  1、OS系统版本

  [root@server ~]# more /etc/redhat-release 

  Red Hat Enterprise LinuxAS release 4 (Nahant Update4)

  2、查看系统是否已经安装DHCP服务端软件 

  [root@server ~]# rpm -qa | grep dhcp

  dhcpv6_client-0.10-14_EL4

  3、将光盘mount上去,然后安装DHCP服务端软件

  [root@server ~]# mount /media/cdrom

  mount: block device /dev/hdc is write-protected, mounting read-only

  [root@server RPMS]# find /media/cdrom -name "dhcp*"

  /media/cdrom/RedHat/RPMS/dhcpv6-0.10-14_EL4.i386.rpm

  /media/cdrom/RedHat/RPMS/dhcpv6_client-0.10-14_EL4.i386.rpm

  /media/cdrom/RedHat/RPMS/dhcp-3.0.1-58.EL4.i386.rpm

  /media/cdrom/RedHat/RPMS/dhcp-devel-3.0.1-58.EL4.i386.rpm

  [root@server RPMS]# rpm -ivh /media/cdrom/RedHat/RPMS/dhcp-3.0.1-58.EL4.i386.rpm

  [root@server RPMS]# rpm -qa | grep dhcp

  dhcp-3.0.1-58.EL4

  dhcpv6_client-0.10-14_EL4

  到这儿已经安装成功了,哈哈 

  4、查看一下,都有那些文件 

  [root@server RPMS]# rpm -ql grep dhcp

  ……

  /etc/dhcpd.conf ——dhcp配置文件

  /etc/rc.d/init.d/dhcpd

  /etc/rc.d/init.d/dhcrelay

  /etc/sysconfig/dhcpd

  /etc/sysconfig/dhcrelay

  /usr/bin/omshell

  /usr/sbin/dhcpd

  /usr/sbin/dhcrelay

  /usr/share/doc/dhcp-3.0.1

  /usr/share/doc/dhcp-3.0.1/README

  /usr/share/doc/dhcp-3.0.1/RELNOTES

  /usr/share/doc/dhcp-3.0.1/dhcpd.conf.sample——dhcp配置文件的模板

  /usr/share/man/man1/omshell.1.gz

  /usr/share/man/man5/dhcp-eval.5.gz

  /usr/share/man/man5/dhcpd.conf.5.gz

  /usr/share/man/man5/dhcpd.leases.5.gz

  /usr/share/man/man8/dhcpd.8.gz

  /usr/share/man/man8/dhcrelay.8.gz

  /var/lib/dhcp

  /var/lib/dhcp/dhcpd.leases ——分配IP的那个日志文件

  5、[root@server RPMS]# more /etc/dhcpd.conf

  这儿有没有什么东东的,还是把模板文件COPY过来吧

  [root@server RPMS]# cp /usr/share/doc/dhcp-3.0.1/dhcpd.conf.sample /etc/dhcpd.conf

  6、查看配置文件,并根据自己的要求更改

  [root@server RPMS]# more /etc/dhcpd.conf

  ddns-update-style interim;

  ignore client-updates;

  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 "wiscom.com.cn";

  option domain-name-servers 219.141.136.10,211.147.6.3;

  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 192.168.0.128 192.168.0.254;

  default-lease-time 21600;

  max-lease-time 43200;

  # 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;

  }

  }

  上面都已经很明了,该配置的都配置了

  7、启动DHCP服务器

  [root@server RPMS]# service dhcpd start

  Starting dhcpd: [ OK ]

  8、查看日志,看看是否有错

  [root@server RPMS]# tail -20 /var/log/messages

  Dec 9 18:05:19 server dhcpd: Wrote 0 deleted host decls to leases file.

  Dec 9 18:05:19 server dhcpd: Wrote 0 new dynamic host decls to leases file.
