Linux DHCP server settings (replicable code)

DHCP server settings

1. Set the DHCP server network address to static assignment first:

Vim/etc/sysconfig/network-*/*-eth0

Device=eth0

Onboot=yes

Bootproto=statics

hwaddr=00:0c:29:56:ea:8a

ipaddr=192.168.1.109

gateway=192.168.1.1

netmask=255.255.255.0

Service Network restart

2. Installing the configuration DHCP server

Yum Install DHCP

Vim/etc/dhcp/dhcpd.conf (later version of linux6)

Vim/etc/dhcpd.conf (version of LINUX5)

Subnet 192.168.1.0 netmask 255.255.255.0 {

Range 192.168.1.1 192.168.1.111; #从192.168.1.1 to 192.168.1.111 (set the address pool yourself)

Option Domain-name-servers 192.168.1.1,8.8.8.8,192.168.1.109; #DNS地址

Option Domain-name "walls.com"; #域名

Option routers 192.168.1.1; #路由器地址

Option Subnet-mask 255.255.255.0; #子网掩码

Option broadcast-address 192.168.1.109; #广播地址 (required within the address pool)

Default-lease-time 21600; #默认租约时间

Max-lease-time 43200; #最大租约时间

}

Host ABC {

Hardware Ethernet 00:0c:29:0a:7b:86; #指定机器MAC地址

Fixed-address 192.168.1.220; #给该机器指定IP地址 (this address is outside the address pool above)

}

When the configuration is complete,

Service DHCPD Restart

PS: If the DHCP server fails to start, check that the configuration file is formatted correctly, or view tail-50/var/log/messages |less

Lazy people can directly copy my configuration file for modification, which I have tested.
