Centors6.5 installation and configuration of DHCP servers

1. DownloadDHCP

Yum-y Install DHCP

2. ConfigurationDHCP MasterServer

Download finished DHCP after service

Step One: cd/etc/sysconfig/network-scripts/

VI Ifcfg-eth0

1. You need to automatically assign an address to Bootproto by DHCP to none.

2. ipaddr fill in the address of the DHCP server.

3. Fill in the default gateway and subnet mask.

Such as:

Step Two: 1.cd/etc/dhcp

2.VI dhcpd.conf

3. modified dhcpd.conf content

#

# DHCP Server Configuration file.

# See/usr/share/doc/dhcp*/dhcpd.conf.sample

# See ' Mans 5 dhcpd.conf '

#

Option Domain-name "archermind.com";

Option Domain-name-servers 192.168.100.101;

FileName "pxelinux.0";

Next-server 172.21.80.30;

Default-lease-time 600;

Max-lease-time 7200;

authoritative;

Subnet 172.21.70.0 netmask 255.255.255.0{

Range DYNAMIC-BOOTP 172.21.70.18 172.21.70.130;

Option Broadcast-address 172.21.70.255;

Option routers 172.21.70.1;

}

Host Test1

{

Hardware Ethernet E8:39:35:43:F9:C8;

Fixed-address 172.21.70.131;

}

Specifies the range of dynamic IPs assigned, at the bottom can be statically fixed assigning IP to the specified MAC address.

The overall process is as follows:

Step three: After the configuration is all complete

Service DHCPD Restart

3. Verifying dynamic fetchingIPand static Access

Looking for another device to connect to the DHCP server, i.e. from the server, dynamic fetch and static fetch all enter the command on the new device:/etc/init.d/network restart

Such as:

Results of dynamic allocations:

Static allocation result: Before dhcpd.conf to fixed Mac on DHCP server

E8:39:35:43:f9:c8 the results of the configuration are as follows:

There is no difference between confirmation and configuration in dhcpd.conf.

Host Test1

{

Hardware Ethernet E8:39:35:43:F9:C8;

Fixed-address 172.21.70.131;

}

4. view the dynamic and static that have been assignedIP

To View assignments: cat/var/lib/dhcpd/dhcpd.leases

Check out the split IP Address : cat/var/lib/dhcpd/dhcpd.leases | grep ^l | sort-u | sed ' s/{//g '

Check out the split MAC Address : cat/var/lib/dhcpd/dhcpd.leases | grep hard | sort-u

Such as:
