rhel5下配置dhcp伺服器

rhel5下配置dhcp伺服器

dhcp 動态配置設定ip位址伺服器

優點:配置設定的ip位址不會重複,可以減輕管理者的負擔

開始配置:

  yum install -y dhcp

  //安裝軟體包

  # cat /etc/dhcpd.conf 

   DHCP Server Configuration file.

   see /usr/share/doc/dhcp*/dhcpd.conf.sample

  //提示去找dhcpd.conf.sample

  # cp /usr/share/doc/dhcp-3.0.5/dhcpd.conf.sample /etc/dhcpd.conf 

  cp: overwrite `/etc/dhcpd.conf'? y

  //将檔案複制過去

  vim /etc/dhcpd.conf

 1 ddns-update-style interim; //DDNS

 2 ignore client-updates; //不允許client更新DNS

 3

 4 subnet 192.168.0.0 netmask 255.255.255.0 {  //要配置設定的網段、子網路遮罩

 5 

 6 # --- default gateway

 7         option routers                  192.168.0.1;  //路由器ip位址

 8         option subnet-mask              255.255.255.0; //子網路遮罩

 9 

10         option nis-domain               "domain.org";//nis伺服器域名現在已經不使用nis伺服器是以要注釋

11         option domain-name              "domain.org";//為客戶設定域名

12         option domain-name-servers      192.168.1.1;  //DNS伺服器的ip位址

13 

14         option time-offset              -18000; # Eastern Standard Time

15 #       option ntp-servers              192.168.1.1;

16 #       option netbios-name-servers     192.168.1.1;

17 # --- Selects point-to-point node (default is hybrid). Don't change this unl    ess

18 # -- you understand Netbios very well

19 #       option netbios-node-type 2;

20 

21         range dynamic-bootp 192.168.0.128 192.168.0.254; //配置設定ip位址的範圍

22         default-lease-time 21600;    //預設租約時間

23         max-lease-time 43200;       //最大租約時間

24 

25         # we want the nameserver to appear at a fixed address

26         host ns {

27                 next-server marvin.redhat.com;

28                 hardware ethernet 12:34:56:78:AB:CD;

29                 fixed-address 207.175.42.254;

30         }

31 }

配置結束,啟動服務

service dhcpd start

使用用戶端測試,将ip獲得方式改為自動獲得,得到ip位址,完成!
