Linux總結筆記10-搭建DHCP服務

1.安裝DHCP 服務程序

[root@linux1 ~]# yum -y install dhcp

2.修改DHCP主配置文件

配置文件模版/usr/share/doc/dhcp-4.2.5/dhcpd.conf.example
[root@linux1 ~]# cat /etc/dhcp/dhcpd.conf 
subnet 192.168.100.0 netmask 255.255.255.0 {
        range 192.168.100.150 192.168.100.200;
        option domain-name-servers 192.168.100.10;
        option domain-name "kangvcar.com";
        option routers 192.168.100.1;
        option broadcast-address 192.168.100.255;
        default-lease-time 600;
        max-lease-time 7200;
host boss {
        hardware ethernet 00:0c:29:23:8f:01;
        fixed-address 192.168.100.123;
}
}

3.啓動DHCP服務

[root@linux1 ~]# systemctl restart dhcpd
[root@linux1 ~]# systemctl enable dhcpd

4.驗證

[root@linux2 ~]# vim /etc/sysconfig/network-scripts/ifcfg-eno16777728
BOOTPROTO=dhcp

[root@linux2 ~]# ifconfig
eno16777728: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.100.123  netmask 255.255.255.0  broadcast 192.168.100.255
