subnet 192.168.0.0 netmask 255.255.255.0 {
  2   range 192.168.0.200 192.168.0.234;
  3   option domain-name-servers 192.168.0.2;
  4   option domain-name "example.com";
  5   option routers 192.168.0.1;
  6   option broadcast-address 192.168.0.255;
  7   next-server 192.168.0.101;
  8   filename "/pxelinux.0";
  9   default-lease-time 600;
 10   max-lease-time 7200;
 11 }

你好，DHCP启动失败多数情况为配置文件错误，这边看到报错信息，可以使用jouernalctl -xe 命令查看报错信息

需要注意的是，

配置文件每行结尾需要使用；结束

域名和引导文件路劲需要加上双引号

重启服务就可以启动了

Answer 2

subnet 192.168.203.0 netmask 255.255.255.0 {
range 192.168.203.100 192.168.203.119;
range 192.168.203.131 192.168.203.200;

default-lease-time 86400;
max-lease-time 86400;

host machine_name {
hardware ethernet 00:0f:1f:b2:11:3d;
fixed-address 192.168.1.100;
}

}
