A.查询MAC地址

B.绑定前的准备

1.资源：

(1) 服务器Server1:192.168.122.1

Server1网络信息如下：

[root@server1 ~]# ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever
2: ens33: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000
    link/ether 00:0c:29:dc:25:fc brd ff:ff:ff:ff:ff:ff
    inet 192.168.3.5/24 brd 192.168.3.255 scope global dynamic noprefixroute ens33
       valid_lft 1097sec preferred_lft 1097sec
    inet6 fe80::7b4c:6610:f082:b301/64 scope link noprefixroute 
       valid_lft forever preferred_lft forever
3: virbr0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000
    link/ether 52:54:00:41:ef:64 brd ff:ff:ff:ff:ff:ff
    inet 192.168.122.1/24 brd 192.168.122.255 scope global virbr0
       valid_lft forever preferred_lft forever
4: virbr0-nic: <BROADCAST,MULTICAST> mtu 1500 qdisc fq_codel master virbr0 state DOWN group default qlen 1000
    link/ether 52:54:00:41:ef:64 brd ff:ff:ff:ff:ff:ff
5: vnet0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel master virbr0 state UNKNOWN group default qlen 1000
    link/ether fe:54:00:b3:28:dd brd ff:ff:ff:ff:ff:ff
    inet6 fe80::fc54:ff:feb3:28dd/64 scope link 
       valid_lft forever preferred_lft forever
[root@server1 ~]# 

(2) 服务器Server1:192.168.122.2

Server2网络信息如下：

[root@server2 ~]# ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever
2: ens3: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000
    link/ether 52:54:00:b3:28:dd brd ff:ff:ff:ff:ff:ff
    inet 192.168.122.2/24 brd 192.168.122.255 scope global noprefixroute ens3
       valid_lft forever preferred_lft forever
    inet6 fe80::2715:6df7:a342:99f7/64 scope link noprefixroute 
       valid_lft forever preferred_lft forever

2. Server1按照dhcp服务

安装命令

yum install -y dhcp

我的服务器已经安装了 dhcp服务，我们来查看一下

[root@server1 ~]# rpm -q dhcp
dhcp-4.4.2-9.uel20.x86_64

C.开始绑定操作

需求：把Server2的IP地址与MAC地址绑定

1.修改dhcp配置文件

vi /etc/dhcp/dhcpd.conf

在下方添加如下代码

host server2 {
        hardware ethernet 52:54:00:b3:28:dd;
        fixed-address 192.168.122.2;
} 

2.生效

systemctl restart dhcpd
