步骤一：给DHCP服务器配置静态ip
[[email protected] ~]# ifconfig eth0 //查看eth0网卡的配置信息
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
[[email protected] ~]# route -n // 查看路由表条目
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
步骤二：
根据要求安装DHCP服务器所需软件包
[[email protected] ~]# rpm -q dhcp // 查看dhcp包是否安装，下面显示未安装
package dhcp is not installed
[[email protected] ~]# mkdir /ww //建立一个文件夹
[[email protected] ~]# mount /dev/cdrom /ww //将系统镜像挂载到/ww目录下
mount: block device /dev/sr0 is write-protected, mounting read-only
[[email protected] ~]# rpm -ivh /ww/Packages/dhcp-4.1.1-34.P1.el6.x86_64.rpm //安装dhcp
warning: /ww/Packages/dhcp-4.1.1-34.P1.el6.x86_64.rpm: Header V3 RSA/SHA256 Signature, key ID fd431d51: NOKEY

步骤三：
产生DHCP服务器配置文件
[[email protected] ~]# cp /usr//share/doc/dhcp-4.1.1/dhcpd.conf.sample /etc/dhcp/dhcpd.conf cp：是否覆盖“/etc/dhcp/dhcpd.conf"？y
步骤四：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服务器地址
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 { //声明网址地址
range 192.168.1.10 192.168.1.100; //设置地址池
option routers 192.168.1.1; //设置默认网关
}
# 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;
}
}
步骤五：启动DHCP服务器
[[email protected] ~]# service dhcpd start
启动 dhcpd： [确定]
步骤六：测试
开一台windows7和dhcp同一网络下，自动获取ip
打开/etc/dhcp/dhcpd.conf 修改第五行host后面的参数 绑定win7的mac 给win7指定的ip
重启dhcp服务 service dhcpd restart
查看win7 的网络连接详细信息
