PXE（Preboot Excute Environment）预启动执行环境，可以让计算机通过网络启动系统，主要用于无人值守安装系统中引导客户端主机安装Linux操作系统。
由于之前有过使用cobbler+kickstart PXE安装系统的博客，这里RHEL7下使用第二种方法。
[root@localhost ~]# yum install -y dhcp
[root@localhost ~]# vim /etc/dhcp/dhcpd.conf
allow booting; allow bootp; ddns-update-style interim; ignore client-updates; subnet 192.168.10.0 netmask 255.255.255.0 { option subnet-mask 255.255.255.0; option domain-name-servers 192.168.10.10; range dynamic-bootp 192.168.10.50 192.168.10.100; default-lease-time 21600; max-lease-time 43200; next-server 192.168.10.10; filename "pxelinux.0"; }
配置完成重启DHCP服务，由于DHCP服务未成功启动也不会报错，所以查看一下DHCPD服务状态
[root@localhost ~]# systemctl restart dhcpd [root@localhost ~]# systemctl status dhcpd dhcpd.service - DHCPv4 Server Daemon Loaded: loaded (/usr/lib/systemd/system/dhcpd.service; disabled) Active: failed (Result: exit-code) since Tue 2019-03-19 10:16:36 EDT; 6s ago Docs: man:dhcpd(8) man:dhcpd.conf(5)
果然启动失败了，配置文件一定有哪里出现错误。
我们执行journal -xe命令查看一下
[root@localhost ~]# journalctl -xe -- -- The start-up result is done.

似乎是eno167777网卡问题，原来我们还原虚拟机后没有将IP修改为DHCP配置文件中对应的192.168.10.10。修改一下。
修改完成后，再次重启DHCPD服务
