Configuration of DHCP servers in Linux

Premise: Set as a DHCP server, the IP address setting of the machine will be in the same network segment of the assigned address range

1. See if the DHCP server is installed

# Rpm-qa | Grepdhcp

2. Install if not installed

# yum Install DHCP

3, installed and then view the installation files, that is, repeat the first step of the operation

4. Locate the file you want to copy

# cat/etc/dhcpd.conf

The following files will appear:

See/usr/share/doc/dhcp*/dhcp.conf.conf.smaple

dhcp-3.0.5 This file

5. Copy this file to a file for example:/etc/dhcpd.conf

# cp–p/usr/share/doc/dhcp-3.0.5/dhcpd.conf.sample/etc/dhcpd.conf

6. Configuring DHCP Files
