Linux DHCP Server Setup

DHCP is a Dynamic Host Configuration protocol that automatically assigns IP addresses, subnet masks, gateways, and DNS TCP/IP information.

Server IP 192.168.1.201

Test requirement: The Linux DHCP server is required to assign an IP address to a Linux client.

First of all:

Yum Install dhcp-y DHCP package

CD/ETC/DHCP Entering the DHCP folder

We can see the contents of the dhcpd.conf file next

Make a copy of this catalogue.

VI dhcpd.conf modified to the following line (simple)

The first line in the red box is the name. The second line is DNS can be modified by itself

Third Row IV behavior lease time size can be modified by itself

The first behavior in the red box is the subnet mask after the self-assigned address network segment

The second line is the range of assigned addresses that you can choose. I'm choosing 220-230.

The third line is the gateway address, you can ping the extranet

The third-step gateway can be configured here as well as above, and at the top it is globally effective

After all this work, you can use the command to comment out all the contents below.

That is, save exit can also be viewed outside to confirm there are no errors

Restart DHCPD/ETC/INIT.D/DHCPD Restart after error

It can then be obtained with other machines (of course, the settings in the Ifcfg-eth0 are for DHCP).

You can then use the command dhclient-d to get the IP address

Get finished to see IP also available IP a look again

Of course, the last few steps are not obvious. But you can do it all by yourself to see the process clearly. Correct.

The above is the simplest DHCP server setup.
