在配置DHCP时报错：

问题描述：
以上报错告诉我，我的DHCP配置的思路错了，原来的配置为
ddns-update-style interim;
ignore client-updates;
allow booting;
allow bootp;
subnet 192.168.1.0 netmask 255.255.255.0 { #subnet 是默认网关，netmask是子网掩码
option routers 192.168.1.1; #为客户端指定网关地址
option subnet-mask 255.255.255.0; #为客户端设定子网掩码
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;}
}
而我本机的IP地址正是报错的192.168.0.10，说明了我的默认网关等都配置错误，应该配置为对应的0网段，而不是1网段（当时是怎么脑挫到1网段的！！！）
解决方案：
重新配置如下：
ddns-update-style interim;
ignore client-updates;
allow booting;
allow bootp;
subnet 192.168.0.0 netmask 255.255.255.0 {
option routers 192.168.0.1;
option subnet-mask 255.255.255.0;
range dynamic-bootp 192.168.0.50 192.168.0.60;
host ns {
hardware ethernet 00:0C:29:93:75:A9;
fixed-address 192.168.0.15;}
}
再次执行/etc/init.d/dhcpd restart
啊啊啊啊啊啊啊，终于成功了
老泪纵横ing！！！！
感觉dhcp的坑我都跳进去过了~~~！！
