在Linux系统中,DHCP(动态主机配置协议)服务器通常使用isc-dhcp-server软件包。配置文件通常位于/etc/dhcp/dhcpd.conf。以下是一些关键参数的详细介绍:

option domain-name 和 option domain-name-serversoption domain-name "example.com";option domain-name-servers ns1.example.com, ns2.example.com;default-lease-time 和 max-lease-timedefault-lease-time 600; # 默认租约时间为10分钟max-lease-time 7200;# 最大租约时间为2小时subnet 块subnet 192.168.1.0 netmask 255.255.255.0 {range 192.168.1.10 192.168.1.100;option routers 192.168.1.1;option subnet-mask 255.255.255.0;option broadcast-address 192.168.1.255;option domain-name-servers 192.168.1.2;}rangerange 192.168.1.10 192.168.1.100;option routersoption routers 192.168.1.1;option subnet-maskoption subnet-mask 255.255.255.0;option broadcast-addressoption broadcast-address 192.168.1.255;host 块host specific-host {hardware ethernet 00:11:22:33:44:55;fixed-address 192.168.1.101;}groupgroup {subnet 192.168.1.0 netmask 255.255.255.0 {range 192.168.1.10 192.168.1.100;option routers 192.168.1.1;}subnet 192.168.2.0 netmask 255.255.255.0 {range 192.168.2.10 192.168.2.100;option routers 192.168.2.1;}}allow 和 denyallow known-clients;deny unknown-clients;log-facilitylog-facility local7;ddns-update-styleddns-update-style interim;ignore client-updatesignore client-updates;on commiton commit {script "/etc/dhcp/dhcpd.post-commit";}on releaseon release {script "/etc/dhcp/dhcpd.post-release";}这些参数可以帮助你配置一个功能齐全的DHCP服务器,满足不同网络环境的需求。根据具体需求,你可以调整和添加更多的配置项。
