DHCP服務

搭建DHCP服務

1）修改網卡配置

vim /etc/sysconfig/network-scripts/ifcfg-eth0
        DEVICE=eth0
        TYPE=Ethernet
        ONBOOT=yes
        NM_CONTROLLED=no
        BOOTPROTO=static
        IPADDR=192.168.1.10
        NETMASK=255.255.255.0

2）安裝DHCP服務

mount /dev/sr0 /mnt/
yum -y install dhcp

3）拷貝修改DHCP主配置文件

cp /usr/share/doc/dhcp-4.1.1/dhcpd.conf.sample /etc/dhcp/dhcpd.conf
vim /etc/dhcp/dhcpd.conf
        option domain-name "benet.com";
        option domain-name-servers 192.168.1.10, 202.106.0.20;
        default-lease-time 600;
        max-lease-time 7200;
        log-facility local7;
        subnet 192.168.1.0 netmask 255.255.255.0 {
        range 192.168.1.105 192.168.1.200;
        option broadcast-address 192.168.1.255;
        option routers 192.168.1.254;
        }
        host windows7 {
        hardware ethernet 40:F0:2F:10:47:8F;
        fixed-address 192.168.1.188;
        }

4）檢查/etc/dhcp/dhcpd.conf文件是否有誤

dhcpd -f

5）重啓服務

service dhcpd restart

6）客戶端測試

vim /etc/sysconfig/network-scripts/ifcfg-eth0
        DEVICE=eth1
        TYPE=Ethernet
        ONBOOT=yes
        NM_CONTROLLED=no
        BOOTPROTO=dhcp

service network restart
ifconfig
