Linux Operations Phase III (II) DHCP services

Linux operation and Maintenance Phase III (II) DHCP services

1, software package:DHCP;

Service Name: Main program DHCPD, Relay service Dhcrelay;

Port:udp67,546, 547;

configuration file:/etc/dhcp/dhcpd.conf master configuration file

/etc/sysconfig/dhcrelay Relay configuration file

/usr/share/doc/dhcp*/dhcpd.conf.sample Master profile template

2. Build Dhcp

server: #yum-y Install DHCP

#cp/usr/share/doc/dhcp*/dhcpd.conf.sample/etc/dhcp/dhcpd.conf

#vi/etc/dhcp/dhcpd.conf Delete redundant configuration, keep a subnet area

Subnet 192.168.1.0 netmask 255.255.255.0 {

Range 192.168.1.10 192.168.1.100;

Option routers 192.168.1.2;

Option Subnet-mask 255.255.255.0;

Option Domain-name-servers 192.168.1.2;

Default-lease-time 21600;

Max-lease-time 23200;

}

client:#vi/etc/sysconfig/network-scripts/ifcfg-eth0

Device=eth0

Onboot=yes

Bootproto=dhcp

#service dhcpd Restart

3. Build DHCP Relay Service:

server: #yum-y Install DHCP

#cp/usr/share/doc/dhcp*/dhcpd.conf.sample/etc/dhcp/dhcpd.conf

#vi/etc/dhcp/dhcpd.conf Delete redundant configuration, keep a subnet area

Subnet 192.168.1.0 netmask 255.255.255.0 {

Range 192.168.1.10 192.168.1.100;

Option routers 192.168.1.2;

Option Subnet-mask 255.255.255.0;

Option Domain-name-servers 192.168.1.2;

Default-lease-time 21600;

Max-lease-time 23200;

}

Subnet 200.200.200.0 netmask 255.255.255.0 {

Range 200.200.200.10 200.200.200.100;

Option routers 200.200.200.1;

Option Subnet-mask 255.255.255.0;

Option Domain-name-servers 200.200.200.1;

Default-lease-time 21600;

Max-lease-time 23200;

}

#service dhcpd Restart

#route Add default GW 192.168.1.2

Relay side:

#yum-y Install DHCP

#vi/etc/sysctl.conf

Net.ipv4.ip_forward=1

#sysctl-P

#vi/etc/sysconfig/dhcrelay

Interface= "Eth0 eth1"

Dhcpserver= "192.168.1.1"

#service dhcrelay Restart

Client:

#vi/etc/sysconfig/network-scripts/ifcfg-eth0

Device=eth0

Onboot=yes

Bootproto=dhcp

#service Network Restart
