dncp的设定
查找dhcp是否安装
ank#rpm -qa |grep dhcp/etc/dhcp.conf;;;;-->主要的设定档
/usr/sbin/dhcpd;;;-->dhcp的daemon的执行档
/var/lib/dhcp/dhcpd/leases-->租约的启动与到期就是记录在这个档案当中设定dhcp.conf
1整体global 含有助于期限,或许还有dns与router的设定等
2动态ip的设定:使用subnet的项目与range的参数来设定要分配出去的ip
3静态ip的设定:使用host这个项目段,配合mac来设定dhcp.conf

#globa
#default -lease-time 259200
#option <参数代码><设定内容> for example :option domain-main "domian.name"

#设定租约期限
default-lease-time 295200
max-lease-time 518400
#2设定领域名称与dns ip
option domain-name "ank.web.cn"
option domain-name-serers 192.165.4.4 , 195.154.4.45
#2动态
subnet 192.168.1.0 netmask 255.255.255.0{
range 192.168.1.21 192.168.1.100
option broadcast-address 192.168.1.255
option routers 192.168.1.2
}
#3静态
host ank-inside{
hardware ethernet 40:95:30:42:B4
fixed-address 192.168.1.5
option broadbast-address 192.168.1.255
option routers 192.168.1.2
}
