OS 下 DHCP 配置
安装 DHCP
# centos6.8
yum install dhcp
# rhel8.3
yum install dhcp-server
# 若要配置启动 ipv6 服务,则还需安装如下服务
yum install radvd # 可为IPv6 DHCP提供路由广播
IPV4 配置
# 配置文件地址:/etc/dhcp/dhcpd.conf
# /etc/dhcp/dhcpd.conf 配置文件如下
ddns-update-style interim;
allow booting;
allow bootp;
ignore client-updates;
set vendorclass = option vendor-class-identifier;
option arch code 93 = unsigned integer 16;
subnet 172.16.0.0 netmask 255.255.128.0 {
# 设置客户端默认网关
option routers 172.16.1.10;
# 设置网络内部DNS服务器的IP地址
option domain-name-servers 172.16.1.10;
# 设置客户端子网掩码
option subnet-mask 255.255.128.0;
# 定义DHCP地址池的服务范围,需排除静态地址
range dynamic-bootp 172.16.10.1 172.16.90.254;
# 设置默认租约时间, 单位: s
default-lease-time 21600;
# 设置最大租约时间
max-lease-time 43200;
# 设置服务器从引导文件中装如主机名,应用于无盘工作站
next-server 172.16.1.10;
class "pxeclients" {
match if substring (option vendor-class-identifier, 0, 9) = "PXEClient";
# if exists user-class and option user-class = "iPXE" {
# filename "ipxe_after/index.ipxe";
# } else {
next-server 172.16.1.10;
if option arch = 00:07 {
# 开始启动文件的名称,应用于无盘工作站

} else if option arch = 00:06 {
filename "efi/snponly.efi";
} else {
# legacy 模式
filename "undionly.kpxe";
}
}
}
# group for Cobbler DHCP tag: default 为一组参数提供声明
group {

# 设置永久 IP 地址

IPV6 配置
# ipv6 配置文件地址:/etc/dhcp/dhcpd6.conf # radvd 服务配置文件地址: /etc/radvd.conf # 注意: 配置文件书写若有误,则dhcpd6 服务无法开启
# /etc/dhcp/dhcpd6.conf 配置文件如下

prefix faaa:a:a:a::/64
{
AdvOnLink on;
AdvAutonomous on;

};
route faaa:a:a:a::/64 {

};
# tftp 服务器地址一定要正确
ipv6 其他配置
# 打开 IPv6 转发功能,否则客户端之间IPv6无法通信
sysctl -w net.ipv6.conf.all.forwarding=1
