1、rpm -qa | grep dhcpd #查看主機是否安裝dhcp包
2、yum install dhcp #用YUM安裝DHCP
3、Linux DHCP配置文件默認是沒有的，可以手動去編寫，或可到/usr/share/doc/dhcp-4.1.1/dhcpd.conf.sample目錄下復制模板到/etc/dhcp/dhcpd.conf目錄下
# cp /usr/share/doc/dhcp*/dhcpd.conf.sample /etc/dhcp/dhcpd.conf
4、編輯配置文件
#vim /etc/dhcp/dhcpd.conf
Linux DHCP配置 單網配置文件
ddns-update-style. interim; #dhcp支持的dns動態更新方式
ignore client-updates; #忽略客戶端DNS動態更新
subnet 192.168.1.0 netmask 255.255.255.0 { #作用域網段
range 192.168.1.11 192.168.1.100; #ip地址段范圍
option routers 192.168.1.253; #網關地址
option subnet-mask 255.255.255.0; #子網掩碼
option domain-name "infogrid.local"; #域名
option domain-name-servers 192.168.1.100,202.96.134.133; #dns IP
option broadcast-address 192.168.1.255; #廣播地址
default-lease-time 86400; #租期1天，秒數
max-lease-time 172800; #最長租期2天
#綁定pc1主機ip地址配置
host pc1 {
hardware ethernet 00:a0:cc:cf:9C:14; #綁定機MAC地址
fixed-address 192.168.1.20; #最長租期2天
}
host pc2 {
hardware ethernet 04:20:c1:f8:37:11;
fixed-address 192.168.1.30;
}
}
Linux DHCP配置 超網配置文件
#vim /etc/dhcp/dhcp.conf
ddns-update-style. interim; #dhcp支持的dns動態更新方式
ignore client-updates; #忽略客戶端DNS動態更新
shared-network mynet { #超網作用域選項，共同部分
option subnet-mask 255.255.255.0; #子網掩碼
option domain-name "infogrid.local"; #域名
option domain-name-servers 192.168.1.100; #dns IP
option broadcast-address 192.168.1.255; #廣播地址
default-lease-time 86400; #租期1天，秒數
max-lease-time 172800; #最長租期2天
subnet 192.168.1.0 netmask 255.255.255.0 { #1.0子網段
range 192.168.1.11 192.168.1.100; #ip地址段范圍
option routers 192.168.1.253; #網關地址
#綁定pc1主機ip地址配置
host pc1 {
hardware ethernet 00:a0:cc:cf:9C:14;
fixed-address 192.168.1.20;
}
#綁定pc2主機ip地址配置
host pc2 {
hardware ethernet 04:20:c1:f8:37:11;
fixed-address 192.168.1.30;
}
}
subnet 192.168.2.0 netmask 255.255.255.0 { #2.0子網段
range 192.168.2.10 192.168.2.100; #ip地址段范圍
option routers 192.168.2.253; #網關地址
}
subnet 192.168.3.0 netmask 255.255.255.0 { #3.0子網段
range 192.168.3.10 192.168.3.100; #ip地址段范圍
option routers 192.168.3.253; #網關地址
}
}
5、Linux DHCP配置 啟動和關閉DHCP服務器
service dhcpd start #開啟dhcp服務
service dhcpd stop #關閉dhcp服務
service dhcpd restart #重啟dhcp服務
6、客戶端獲取IP 地址
7、Linux DHCP配置 查看地址池中已經分配的IP記錄
cat /var/lib/dhcpd/dhcpd.leases
