动态分配IP地址
实验环境
服务器和客户端仅主机方式连接
DHCP:
安装包:
yum install dhcp
端口(udp):67
配置文件:/etc/dhcp/dhcpd.conf
需要拷贝
cp /usr/share/doc/dhcp-4.2.5/dhcpd.conf.example /etc/dhcp/dhcpd.conf
启动服务: systemctl restart dhcpd
日志:/var/log/messages
工作原理:
C ---------DHCP DISCOVER --------> S
C
C----------DHCP REQUEST----------> S
C
配置:
vim /etc/dhcp/dhcpd.conf
subnet 172.16.100.0 netmask 255.255.255.0 { 写自己的网关 ip addr
range 172.16.100.101 172.16.100.200; -----写范围
option domain-name-servers 202.106.0.20;
option domain-name "internal.example.org";
option routers 172.16.100.1; --------写网段 route -n
option broadcast-address 172.16.100.255; 自己的广播地址
default-lease-time 600;
max-lease-time 7200;
}
systemctl restart dhcpd
客户端
nmcli con add con-name dhcp ifname eno16777736 autoconnect no type Ethernet
nmcli con up dhcp
ip addr s
租约文件:
服务端:/var/lib/dhcpd/dhcpd.leases
客户端:/var/lib/dhclient/
指定ip地址分配
host client1 {
hardware ethernet 00:0c:29:64:d6:87;
fixed-address 172.16.100.250;
}
服务端：
客户端：
手动切换ip
直接添加
