Quick configuration of DHCP server configuration in Linux

Article Title: Quickly configure DHCP server configurations in Linux. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.

In the past, we have learned the basic content of the DHCP service, and we have also learned how to configure DHCP servers in Windows. Next we will mainly explain the configuration of the Linux DHCP server.

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

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
