linux新手，目前在学习linux中，今天在学习搭建PXE+kickstart无人安装的时候需要配置DHCP服务，我按着要求配置了DHCP服务，但是还是无法启动。
1.下面为dhcp.conf配置文件
[root@test-pxe ~]# cat /etc/dhcp/dhcpd.conf
ddns-update-style none;
ignore client-updates;
subnet 192.168.99.0 netmask 255.255.255.0 {
range 192.168.99.2 192.168.99.250;
option subnet-mask 255.255.255.0;
default-lease-time 21600;
max-lease-time 43200;
next-server 192.168.100.100;
filename "/pxelinux.0";
}
2.因为涉及到多块网卡，我从网上找了下资料编辑了/etc/sysconfig/dhcpd,在下面增加了一行。
DHCPDARGS=eno16777736
3.使用systemctl start dhcpd.service的时候报如下错误：
[root@test-pxe ~]# systemctl start dhcpd
Job for dhcpd.service failed because the control process exited with error code. See "systemctl status dhcpd.service" and "journalctl -xe" for details.
4.通过systemctl status dhcpd.service，有如下报错，也姑姑了下面的报错信息，但是确实没有找到有用的解决方法。
[root@test-pxe ~]# systemctl status dhcpd.service
● dhcpd.service - DHCPv4 Server Daemon
