Build DHCP server under Linux

I. DHCP-REQUIRED Packages
Dhcp-common-4.1.1-34.pl.el6.centos.x86_64
Dhcp-4.1.1-34.pl.el6.centon.x86_64
Two. Edit the master configuration file

vi/etc/dhcp/dhcpd.confddns-update-style interim;ignore client-updates;shared-network ifs {        option domain-name      "ifs.com";        option domain-name-servers 192.168.0.1;        default-lease-time 21600;       max-lease-time  43200;subnet 192.168.0.0 netmask 255.255.0.0 {        option routers                192.168.0.1;       option subnet-mask            255.255.0.0;       option  time-offset           -18000;        range dynamic-bootp 192.168.0.10 192.168.0.15;}} 

1, Ddns-update-style type definition supported DNS dynamic update type (required), generally we set to off
closed, interim and none are closed meaning,
2, subnet network number netmask subnet mask This is used to indicate the scope of
3, option routers Gateway
4, Option subnet-mask Subnet mask
5, Option Nis-domain NIS, if not commented out
6, option Domain-name Domain name
7, option domain-name-servers DNS server IP
8, range DYNAMIC-BOOTP IP address ranges
9, Default-lease-time 21600; Address lease Time
10, max-lease-time 43200, lease maximum time
11, host NS {
next-servermarvin.redhat.com;
Hardware Ethernet 12:34:56:78:AB:CD;
Fixed-address 207.175.42.254;
} This is a special declaration, used to do the address and Mac binding, hardware Ethernet for the hardware type Ethernet
Network and then write the MAC address, fixed-address is to bind to the above Mac IP address.

Note: After each line of the parameters must have ";" to end, otherwise is the configuration error, unable to start the service, with the
Body format is:

Shared-network The name of the superscope {
Global parameters, for all scopes to take effect, You can write the
DNS address, the lease time, and so on, each line is finished with ";" End
(first scope): Subnet network number netmask subnet mask {
Scope parameter settings, see the individual situation to set, each line finished with ";" End
}
(second scope): Subnet network number netmask subnet mask {
The parameter settings of the scope, see the individual situation to set, each line finished with ";" End
}
}
The format is like this, the wording is more flexible.
Three. Start the DHCP service

Four. DHCP Log debug
