各位前輩,小弟目前要在CentOS6.5 架設 單網卡發多網段,與VLAN 的DHCP Server
因找到前資訊主管留下的設定方式 在終端機輸入 service dhcpd start 啟動失敗
從/var/log/messages 底下看到下列訊息,是否能提示小弟我哪裡需要設定的

------log中的錯誤訊息

設定要派發的網卡
/etc/sysconfig/dhcpd

DHCPDARGS="eth0.2 eth0.3 eth0.5 eth0.8 eth0.10 eth0.11 eth0.12 eth0.13 eth0.14 eth0.15 eth0.16 eth0.17 eth0.18 eth0.19 eth0.20 eth0.21 eth0.22"


-------------------------------------------------------------------


開機自動載入腳本
檔案位置↓↓↓
/etc/rc.loacl

#!/bin/sh



touch /var/lock/subsys/local


/sbin/modprobe -a 8021q
 載入802.q模組

/sbin/vconfig add eth0 2  新增虛擬網卡掛載再eth0,vlan2
ifconfig eth0.2 192.168.1.3 netmask 255.255.255.0

  設定eth0.22的interface IP為192.168.1.3/24

/sbin/vconfig add eth0 3

ifconfig eth0.3 192.168.10.3 netmask 255.255.255.0


/sbin/vconfig add eth0 5

ifconfig eth0.5 192.168.12.3 netmask 255.255.255.0


/sbin/vconfig add eth0 8

ifconfig eth0.8 192.168.8.3 netmask 255.255.255.0

略.....

service dhcpd start



    起動dhcpd
