linux dhcp服务启动不了！求高手相助啊.... 之后service dhcpd start 失败

我的配置文件是这样的！还是不行

Answer 1

多作用域配置，建议你先看下日志吧/var/log/messages
看你的配置文件也没找出什么问题，另外我配了下没什么问题，你可以看下配置，#表示注释行：
[root@localhost ~]# cat /etc/dhcpd.conf
ddns-update-style interim;
ignore client-updates;

subnet 192.168.81.0 netmask 255.255.255.0 {

option routers 192.168.81.1;
option subnet-mask 255.255.255.0;

option domain-name-servers 192.168.81.1;

option time-offset -18000; # Eastern Standard Time

range dynamic-bootp 192.168.81.128 192.168.81.254;
default-lease-time 21600;
max-lease-time 43200;

# we want the nameserver to appear at a fixed address
# host ns {
# next-server marvin.redhat.com;
# hardware ethernet 12:34:56:78:AB:CD;
# fixed-address 207.175.42.254;
# }
}

subnet 172.16.0.0 netmask 255.255.0.0 {

option routers 172.16.1.1;
option subnet-mask 255.255.0.0;

option domain-name-servers 192.168.81.1;

option time-offset -18000; # Eastern Standard Time

range dynamic-bootp 172.16.1.100 172.16.1.200;
default-lease-time 21600;
max-lease-time 43200;

# we want the nameserver to appear at a fixed address
# host ns {
# next-server marvin.redhat.com;
# hardware ethernet 12:34:56:78:AB:CD;
# fixed-address 207.175.42.254;
# }
}
[root@localhost ~]#

修改你的/etc/dhcpd.conf文件，配置你的服务器网络

追问

你看我的配置对吗ddns-update-style none;
ignore clinet-updates;
subnet 192.168.1.0 netmask 255.255.255.0{
#----default gateway
option routers 192.168.1.1;
option subnet-make 255.255.255.0;
option domaic-name-servers 192.168.1.1;
range dynamic-bootp 192.168.1.128 192.168.1.254
default-lease-time 21600;
max-lease-time 43200;
}

追答

这行后面应该有个分号——range dynamic-bootp 192.168.1.128 192.168.1.254
你分的ip不能和你现在网段上用的ip冲突，你再试试

追问

分号是我少打了！我自己ip是192.168.1.2
谢谢你那么热心的帮助我啊

追答

呵呵客气了，因为最近我也在为我的DHCP服务器烦恼，也有些莫名其妙的问题。

但是重启是好的对不对。
去杀掉一些锁住的文件。你看日志所说了为啥不出的错。
