Linux架設(shè)DHCP服務(wù)器的方法

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

Red Hat Enterprise Linux AS release 4 (Nahant Update 4)

2、查看系統(tǒng)是否已經(jīng)安裝DHCP服務(wù)端軟件

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

dhcpv6_client-0.10-14_EL4

3、將光盤mount上去，然后安裝DHCP服務(wù)端軟件

[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

到這兒已經(jīng)安裝成功了，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的那個(gè)日志文件

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

這兒有沒(méi)有什么東東的，還是把模板文件COPY過(guò)來(lái)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，并根據(jù)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;

}

}

上面都已經(jīng)很明了，該配置的都配置了

7、啟動(dòng)DHCP服務(wù)器啦

[root@server RPMS]# service dhcpd start

Starting dhcpd: [ OK ]

8、查看日志，看看是否有錯(cuò)

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