DHCP 很常见,自动分配 IP 地址子网掩码,默认网关等,还可以结合其他服务做远程无人值守安装服务器.

配置步骤

root@ns1:~# apt -y install isc-dhcp-server
root@ns1:~# vi /etc/default/isc-dhcp-server
# line 4: uncomment
DHCPDv4_CONF=/etc/dhcp/dhcpd.conf
# line 17,18: specify listening interfaces
# if not use IPv6, comment out it
INTERFACESv4="ens3"
INTERFACESv6="ens3"
root@ns1:~# vi /etc/dhcp/dhcpd.conf
# line 7: specify domain name
option domain-name "yoyojacky.com";
# line 8: specify nameserver's hostname or IP address
option domain-name-servers ns1.yoyojacky.com;
# line 21: uncomment
authoritative;
# add to the end
# specify network address and subnet-mask
subnet 10.0.0.0 netmask 255.255.255.0 {
     # specify default gateway
     option routers 10.0.0.1;
     # specify subnet-mask
     option subnet-mask 255.255.255.0;
     # specify the range of leased IP address
     range dynamic-bootp 10.0.0.200 10.0.0.254;
}
root@ns1:~# systemctl restart isc-dhcp-server 

基本上就搞定了,测试 linux 用 dhclient 获取一下,windows 用 ipconfig /release 和/renew.
