CentOS 6.5 架設DHCP Server


先輸入下方指令安裝dhcp
yum install -y dhcp


輸入下方指令編輯配置檔
vim /etc/dhcp/dhcpd.conf


配置檔:
ddns-update-style interim;
ignore client-updates;
#subnet = IP範圍, netmask = 遮罩
subnet 192.168.1.0 netmask 255.255.255.0 { 
  range 192.168.1.10 192.168.1.240; #IP Range
  option domain-name-servers 192.168.40.13; #DNS Server IP
  option domain-name "cy.local"; #DNS
  option routers 192.168.1.254; #閘道
  default-lease-time 10000; #預設租約時間
  max-lease-time 15000; #最長租約時間
}

輸入下方指令設定DHCP網卡:
vim /etc/sysconfig/dhcpd



設定完後就輸入下方指令啟動DHCP Server
service dhcp start


無法啟動可以查看/var/log/message
最常見錯誤可可能是網卡的IP與設定檔的IP不符合
配置檔可以參考/usr/share/doc/dhcp-???/dhcpd.conf.sample
