Protocol basics: Linux DHCP server configuration

For DHCP, configuration is required in many cases in Linux. Here we will also explain the configuration of the Linux DHCP server. Let's help you understand this knowledge. The specific configuration is as follows:

Linux DHCP server configuration

1. Install the Linux DHCP service package

RHEL4 fourth disc, dhcp-3.0.1-12_EL.i386.rpm

Mount/dev/cdrom/media/cdrom/

Install the DHCP package before configuring the Linux DHCP server

 
 

  
  
rpm -ivh /media/cdrom/RedHat/RPMS/dhcp-3.0.1-12_EL.i386.rpm 
 
 

2. dhcp. conf configuration file parsing

Copy the sample file to/etc/

 
 

  
  
cp /usr/share/doc/dhcp-3.0.1/dhcpd.conf.sample /etc/dhcpd.conf 
 
 

Linux DHCP server configuration instance

 
 

  
  
Ddns-update-style interim;  
  
  
Ignore client-updates;  
  
  
Subnet  10.0.0.0  netmask  255.0.0.0  {          
  
  
# --- default gateway  
  
  
option routers                   “10.0.0.0.1”;  
  
  
option subnet-mask              “255.0.0.0”;  
  
  
#       option nis-domain                “domain.org”;  
  
  
#       option domain-name              "domain.org";  
  
  
#       option domain-name-servers       10.0.0.1;  
  
  
#       option time-offset              -18000; # Eastern Standard Time  
  
  
#       option ntp-servers              192.168.1.1;  
  
  
#       option netbios-name-servers     192.168.1.1;  
  
  
# --- Selects point-to-point node (default is hybrid). Don't change this unless  
  
  
# -- you understand Netbios very well  
  
  
#       option netbios-node-type 2;   
  
  
range dynamic-bootp 10.0.0.100 10.0.0.200;  
  
  
default-lease-time 21600;  
  
  
max-lease-time 43200;  
  
  
"/etc/dhcpd.conf" 31L, 852C          1,1            
  
  
# we want the nameserver to appear at a fixed address  
  
  
host ns {  
  
  
next-server marvin.redhat.com;  
  
  
hardware ethernet 12:34:56:78:AB:CD;  
  
  
fixed-address 207.175.42.254;  
  
  
}  
  
  
} 
 
 

3. configuration files are required for multiple network interfaces of the Linux DHCP server.

 
 

  
  
/Etc/sysconfig/dhcpd
  
  
DHCPDARGS = [network interface]
 
 

4. Start the dhcpd Service

 
 

  
  
Service dhcpd start 
 
 

5. Configure the client to dynamically obtain the IP address

The above is the process of configuring the Linux DHCP server.
