2、是的，您没有看错！打开dhcpd服务程序的主配置文件发现只有3行注释语句，大意是告诉咱们配置文件需要全部由自己来写，如果不熟悉的话可以看下第2行中的参考示例文件，再或者买本刘遄老师的《Linux就该这么学》自学书籍吧~哈哈，最后一句是玩笑了。如图所示，一个标准的DHCP配置文件应该包括全局配置参数、子网网段声明、地址配置选项以及地址配置参数：

[root@linuxprobe ~]# cat /etc/dhcp/dhcpd.conf 

# DHCP Server Configuration file. 

# see /usr/share/doc/dhcp*/dhcpd.conf.example 

# see dhcpd.conf(5) man page
