dhcp centos

DHCP (Dynamic Host Configuration Protocol) is a network protocol that is used to assign IP addresses and other network configuration parameters to devices on a network automatically. CentOS is a Linux distribution that is widely used in servers and workstations. In this article, we will discuss how to install and configure DHCP server on CentOS.

Step 1: Install DHCP Server on CentOS

To install DHCP server on CentOS, follow these steps:

1. Open a terminal window and log in as root or use the sudo command.

2. Type the following command to install the DHCP server package:

yum install dhcp

3. Once the installation is complete, you can verify it by typing the following command:

rpm -qa | grep dhcp

You should see a package named dhcp-<version> installed.

Step 2: Configure DHCP Server on CentOS

To configure DHCP server on CentOS, follow these steps:

1. Open the DHCP server configuration file using your preferred text editor. In this example, we will use nano:

nano /etc/dhcp/dhcpd.conf

2. Uncomment the following lines to define the network settings:

subnet 192.168.1.0 netmask 255.255.255.0 {
  range 192.168.1.10 192.168.1.100;
  option routers 192.168.1.1;
  option domain-name-servers 192.168.1.1;
}

The above configuration defines a subnet with a range of IP addresses from 192.168.1.10 to 192.168.1.100. It also specifies the router's IP address and the domain name server's IP address.

3. Save the changes and exit the editor.

4. Start the DHCP server service by typing the following command:

systemctl start dhcpd

5. Check the status of the DHCP server service by typing the following command:

systemctl status dhcpd

You should see a message indicating that the service is active and running.

Step 3: Test DHCP Server on CentOS

To test DHCP server on CentOS, follow these steps:

1. Connect a device to the network that is configured to obtain IP address automatically.

2. Check the IP address assigned to the device by typing the following command:

ip addr show

You should see an IP address in the range specified in the DHCP server configuration file.

That's it! You have successfully installed and configured DHCP server on CentOS. You can now use this server to automatically assign IP addresses to devices on your network.
