linux DHCP服務器的配置（redhat6.4）

步驟一：給DHCP服務器配置靜態ip

[root@localhost ~]# ifconfig eth0         //查看eth0網卡的配置信息

eth0      Link encap:Ethernet  HWaddr 00:0C:29:0C:C3:1F  

          inet addr:192.168.1.33  Bcast:192.168.1.255  Mask:255.255.255.0

          inet6 addr: fe80::20c:29ff:fe0c:c31f/64 Scope:Link

          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1

          RX packets:2519 errors:0 dropped:0 overruns:0 frame:0

          TX packets:2644 errors:0 dropped:0 overruns:0 carrier:0

          collisions:0 txqueuelen:1000 

          RX bytes:1806182 (1.7 MiB)  TX bytes:1671573 (1.5 MiB)

          Interrupt:18 Base address:0x2000 

[root@localhost ~]# route -n        //   查看路由表條目 

Kernel IP routing table

Destination     Gateway         Genmask         Flags Metric Ref    Use Iface

192.168.1.0     0.0.0.0         255.255.255.0   U     0      0        0 eth0

0.0.0.0         192.168.1.1     0.0.0.0         UG    0      0        0 eth0

步驟二：

根據要求安裝DHCP服務器所需軟件包

[root@localhost ~]# rpm -q dhcp       // 查看dhcp包是否安裝，下面顯示未安裝

package dhcp is not installed

[root@localhost ~]# mkdir /ww         //創建一個文件夾

[root@localhost ~]# mount /dev/cdrom /ww    //將系統鏡像掛載到/ww目錄下

mount: block device /dev/sr0 is write-protected, mounting read-only

[root@localhost ~]# rpm -ivh /ww/Packages/dhcp-4.1.1-34.P1.el6.x86_64.rpm    //安裝dhcp

warning: /ww/Packages/dhcp-4.1.1-34.P1.el6.x86_64.rpm: Header V3 RSA/SHA256 Signature, key ID fd431d51: NOKEY

[root@localhost ~]# 

步驟三：

產生DHCP服務器配置文件

[root@localhost ~]# cp /usr//share/doc/dhcp-4.1.1/dhcpd.conf.sample /etc/dhcp/dhcpd.conf      cp：是否覆蓋「/etc/dhcp/dhcpd.conf"？y             

步驟四：配置/etc/dhcp/dhcpd.conf配置文件

# dhcpd.conf

#

# Sample configuration file for ISC dhcpd

#

# option definitions common to all supported networks...

option domain-name "example.org";

option domain-name-servers 8.8.8.8， 4.4.4.4;      //指定dns服務器地址

default-lease-time 600;

max-lease-time 7200;

# Use this to enble / disable dynamic dns updates globally.

#ddns-update-style none;

# 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.

subnet 192.168.1.0 netmask 255.255.255.0 {           

}

# This is a very basic subnet declaration.

subnet 192.168.1.0 netmask 255.255.255.0 {        //聲明網址地址

  range 192.168.1.10 192.168.1.100;              //設置地址池

  option routers 192.168.1.1;                     //設置默認網關

}

# 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.   Hosts for which no fixed address is specified can only

# be booted with DHCP, unless there is an address range on the subnet

# to which a BOOTP client is connected which has the dynamic-bootp flag

# set.

host fantasia {

  hardware ethernet 08:00:07:26:c0:a5;

  fixed-address fantasia.fugue.com;

}

# You can declare a class of clients and then do address allocation

# based on that.   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;

  }

}

步驟五：啓動DHCP服務器

[root@localhost ~]# service dhcpd start

啓動 dhcpd：                                               [肯定]

步驟六：測試

開一臺windows7和dhcp同一網絡下，自動獲取ip

  打開/etc/dhcp/dhcpd.conf     修改第五行host後面的參數 綁定win7的mac 給win7指定的ip

重啓dhcp服務 service dhcpd restart

查看win7 的網絡鏈接詳細信息
