狀態錯誤，檢視dhcp配置檔案vim /etc/dhcp/dhcpd.conf[[email protected] ~]# systemctl status dhcpd ● dhcpd.service - DHCPv4 Server Daemon Loaded: loaded (/usr/lib/systemd/system/dhcpd.service; disabled; vendor preset: disabled) Active: failed (Result: exit-code) since 四 2018-03-01 17:19:40 CST; 12s ago Docs: man:dhcpd(8) man:dhcpd.conf(5) Process: 4879 ExecStart=/usr/sbin/dhcpd -f -cf /etc/dhcp/dhcpd.conf -user dhcpd -group dhcpd --no-pid (code=exited, status=1/FAILURE) Main PID: 4879 (code=exited, status=1/FAILURE) 3月 01 17:19:40 bogon dhcpd[4879]: on ftp.isc.org.

配置如下
subnet 192.168.15.0 netmask 255.255.255.0 {
range 192.168.15.100 192.168.15.199;
option routers 192.168.15.2;
option subnet-mask 255.255.255.0;
default-lease-time 21600;
max-lease-time 43200;
next server 192.168.15.201;
filename "/pxelinux.0";
}
配置next-server要帶連字元“-”修改後subnet 192.168.15.0 netmask 255.255.255.0 {
range 192.168.15.100 192.168.15.199; #可分配起始IP-結束IP
