/etc/resolv.conf 文件
主配置文件:/etc/dhcp/dhcpd.conf
执行程序:/usr/sbin/dhcpd、/usr/sbin/dhcrelay
服务脚本:/etc/init.d/dhcpd、/etc/init.d/dhcrelay
执行参数配置:/etc/sysconfig/dhcpd
DHCP中继配置:/etc/sysconfig/dhcrelay
DHCP
/etc/dhcp/dhcpd.conf
全局设置,作用于整个DHCP服务器
ddns -update-style none;
default-lease-time 21600;
max-lease-time 43200;
option domain-name "domain.org";
option domain-name-servers 202.106.0.20;
Subnet网络声明,作用于整个子网段
range参数:设置用于分配的ip地址
option subnet-mask 参数: 设置客户机的子网掩码
option routers 参数:设置客户机的默认网关地址
subnet 192.168.4.0 netmask 255.255.255.0{
range 192.168.4.128 192.168.4.254;
option subnet-mask 255.255.255.0;
option routers 192.168.4.1
}
host主机声明,作用于单个主机
hardware ethernet 参数:指定对应主机的MAC地址
fixed-address 参数:指定为该主机
host prtsvr{
hardware ethernet 00:v0:77:44;
fixed-address 192.168.4.100
}
启动DHCP服务
netstat -anpu | grep :67
查看租约文件
/var/lib/dhcpd/dhcpd.leases
使用方式
1、修改网卡配置文件
2、使用dhclient命令
dhclient -d eth0
ddns-update-style none;
default-lease-time 21600;
max-lease-time 43200;
option domain-name "domain.org";
option domain-name-servers 202.106.0.20;
subnet 192.168.111.0 netmask 255.255.255.0 {
range 192.168.111.10 192.168.111.253;
option subnet-mask 255.255.255.0;
option routers 192.168.111.1;
# host prtsvr {
# hardware ethernet 00:0C:29:E7:64:E8;
#: fixed-address 192.168.111.100;
# }
}
