配置DHCP，vi /etc/dhcp/dhcp.conf文件配置如下：

ddns-update-style interim;
    ignore client-updates;
    allow booting;
    allow bootp;
    subnet 192.168.1.1 netmask 255.255.255.0 {
    option routers 192.168.1.1;
    option subnet-mask 255.255.255.0;
    
    range  dynamic-bootp  192.168.1.50 192.168.1.60;
    
    host ns {
    hardware ethernet  00:0C:29:93:75:A9;
    fixed-address 192.168.1.15;}
    }

配置完成后执行/etc/init.d/dhcp restart,重新启动dhcp

### 问题描述： ###

由以下描述可知，问题出现在subnet 192.168.1.1 netmask 255.255.255.0这一行  
 subnet 192.168.1.1 netmask 255.255.255.0  
^  
dhcpd: Configuration file errors encountered -- exiting

### 解决方案： ###

修改vi /etc/dhcp/dhcp.conf

subnet 192.168.1.1 netmask 255.255.255.0 ---》 subnet 192.168.1.0 netmask 255.255.255.0

ddns-update-style interim;
    ignore client-updates;
    allow booting;
    allow bootp;
    subnet 192.168.1.0 netmask 255.255.255.0 {
    option routers 192.168.1.1;
    option subnet-mask 255.255.255.0;
    
    range  dynamic-bootp  192.168.1.50 192.168.1.60;
    
    host ns {
    hardware ethernet  00:0C:29:93:75:A9;
    fixed-address 192.168.1.15;}
    }

继续执行：/etc/init.d/dhcp restart
