Article Title: Install the DHCP service and configuration at rpm 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.

Configuration of DHCP server in Linux

[Root @ loaclhost/] mount/dev/hdc // mount the disc to/dev/

[Root @ loaclhost/] cd hdc/Server // enter the Server Directory of the Disk

[Root @ loaclhost Server] rpm? Ivh dhcp-3.0.5-7.el5.i386.rpm // rpm server side for DHCP Installation

[Root @ loaclhost Server] cp/usr/share/doc/dhcp-3.0.5/dhcpd. conf. sample/etc/dhcpd. conf // set/etc/dhcpd. replace conf with/usr/share/doc/dhcp-3.0.5/dhcpd. conf. sample

// Tips: by default, the DHCP server does not have a configuration file. You need to copy the sample from the/usr directory and then modify it. If you are a skilled engineer, you can create it directly.

[Root @ loaclhost Server] cd/etc

[Root @ loaclhost etc] vi dhcpd. conf

Note: In the configuration file, the orange part is the global configuration, the blue part is the opportunity MAC, and the host name is assigned a static IP.

[Root @ localhost etc] ifconfig eth0 192.168.0.1

[Root @ localhost etc] service dhcpd restart // restart the dhcpd service
