DHCP簡單配置（1）

RHEL5 基本網絡配置

1、

1 、RHEL5：如圖1

（如圖1）

2 、#hostname //查看當前主機的主機名：如圖2

（如圖2）

3 、#vi /etc/sysconfig/network-scripts/ifcfg-eth0 編輯指定網絡接口配置文件：如圖3

（如圖3）

4 、#vi /etc/sysconfig/network 經過配置文件修改主機名：如圖4

（如圖4）

5 、#vi /etc/syconfig/i18n在終端字符界面修改其字體和中文字體大小：如圖5

（如圖5）

6 、掛載光盤：如圖6

（如圖6）

7 、查看OpenSSH是否安裝：如圖7

（如圖7）

8 、 #vi /etc/hosts 設置本地 DNS 解析文件： 如圖8

（如圖8）

9 、 #vi /etc/resolv.conf 指定當前主機的 DNS 服務器，最多可指定三個： 如圖9

（如圖9）

10 、關閉iptables防火牆：如圖10

（如圖10）

2、DHCP簡單配置

一、掛載並查詢dhcp是否安裝：

[root@dhcp ~]# mount /dev/hdc /mnt/dvd/

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

[root@dhcp ~]# cd /mnt/dvd/Server/

[root@dhcp Server]# rpm -qa | grep dhcp

dhcpv6_client-0.10-33.el5

[root@dhcp Server]# ls -l dhcp*

-rw-r--r-- 110 root root 894361 2007-06-28 dhcp-3.0.5-7.el5.i386.rpm

-rw-r--r-- 125 root root 132573 2007-06-28 dhcp-devel-3.0.5-7.el5.i386.rpm

-rw-r--r-- 110 root root 218171 2007-01-18 dhcpv6-0.10-33.el5.i386.rpm

-rw-r--r-- 115 root root 80927 2007-01-18 dhcpv6_client-0.10-33.el5.i386.rpm

 

2 、安裝 dhcp 並查詢

[root@dhcp Server]# rpm -ivh --aid dhcp-3.0.5-7.el5.i386.rpm

warning: dhcp-3.0.5-7.el5.i386.rpm: Header V3 DSA signature: NOKEY, key ID 37017186

Preparing... ########################################### [100%]

1:dhcp ########################################### [100%]

[root@dhcp Server]# rpm -ivh dhcp-devel-3.0.5-7.el5.i386.rpm

warning: dhcp-devel-3.0.5-7.el5.i386.rpm: Header V3 DSA signature: NOKEY, key ID 37017186

Preparing... ########################################### [100%]

1:dhcp-devel ########################################### [100%]

[root@dhcp Server]# rpm -ivh dhcpv6-0.10-33.el5.i386.rpm

warning: dhcpv6-0.10-33.el5.i386.rpm: Header V3 DSA signature: NOKEY, key ID 37017186

Preparing... ########################################### [100%]

1:dhcpv6 ########################################### [100%]

[root@dhcp Server]# rpm -qa | grep dhcp

dhcp-devel-3.0.5-7.el5

dhcpv6-0.10-33.el5

dhcpv6_client-0.10-33.el5

dhcp-3.0.5-7.el5

 

3 、複製模板文件 dhcpd.conf.sample 到 /etc 目錄下名爲 dhcpd.conf

[root@dhcp Server]# cd /usr/share/doc/dhcp-3.0.5/

[root@dhcp dhcp-3.0.5]# ls

api+protocol draft-ietf-dhc-failover-07.txt RELNOTES rfc2485.txt

dhcpd.conf.sample IANA-arp-parameters rfc1542.txt rfc2489.txt

draft-ietf-dhc-authentication-14.txt ja_JP.eucJP rfc2131.txt rfc951.txt

draft-ietf-dhc-dhcp-dns-12.txt README rfc2132.txt

[root@dhcp dhcp-3.0.5]# cp dhcpd.conf.sample /etc/dhcpd.conf

cp：是否覆蓋「/etc/dhcpd.conf」? y

[root@dhcp dhcp-3.0.5]# cd

 

4 、修改 /etc/dhcp.conf 內容，注意加黑字體是修改內容

[root@dhcp ~]# vim /etc/dhcpd.conf

ddns-update-style interim;

ignore client-updates;

subnet 10.2.11 .0 netmask 255.255.255.0 { （修改 10.2.11.0 網段）

# --- default gateway

option routers 10.2.11 .1; （修改網關）

option subnet-mask 255.255.255.0; （子網掩碼）

option nis-domain "domain.org";

option domain-name " benet.com"; （ 修改域名）

option domain-name-servers 202.106.46.151; （設置 dns ）

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 10.2.11 .200 10.2.11.230; （獲取 IP 地址網段）

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;

}

}

"/etc/dhcpd.conf" 31L, 844C 已寫入

 

5 、啓動 dhcpd 服務

[root@dhcp ~]# service dhcpd restart

關閉 dhcpd： [失敗]

啓動 dhcpd： [肯定]

[root@dhcp ~]# chkconfig --list dhcpd

dhcpd 0:關閉 1:關閉 2:關閉 3:關閉 4:關閉 5:關閉 6:關閉

[root@dhcp ~]# chkconfig --level 2345 dhcpd on

[root@dhcp ~]# chkconfig --list dhcpd

dhcpd 0:關閉 1:關閉 2:啓用 3:啓用 4:啓用 5:啓用 6:關閉

 

6 、客戶機測試

 

7 、能夠指定用戶獲取的 IP

# we want the nameserver to appear at a fixed address

host ns ( 修改主機名如： honglin) {

next-server marvin.redhat.com;

hardware ethernet 12:34:56:78:AB:CD; （修改 MAC 地址）

fixed-address 207.175.42.254; ( 修改 IP 如： 10.2.11 .229)

}

 

[root@dhcp ~]# cat  /var/lib/dhcpd/dhcpd.leases

# All times in this file are in UTC (GMT), not your local timezone.   This is

# not a bug, so please don't ask about it.   There is no portable way to

# store leases in the local timezone, so please don't request this as a

# feature.   If this is inconvenient or confusing to you, we sincerely

# apologize.   Seriously, though - don't ask.

# The format of this file is documented in the dhcpd.leases(5) manual page.

lease 10.2.11 .230 {

  starts 3 2009/11/18 08:41:43;

  ends 3 2009/11/18 14:41:43;

  tstp 3 2009/11/18 14:41:43;

  binding state active;

  next binding state free;

  hardware ethernet 00:24: 8c :15:97:28;

  uid "\001\000$\214\025\227(";

  client-hostname "PC-200910272235";

}

[root@dhcp ~]#
