In this lab I will demonstrate how to configure DHCP server in Centos 7 and how the clients get the IP from the server. Basically clients get TCP/IP information including IP address, subnet mask, default gateway and DNS server address from the server.
Here Server is Centos 7 and client machines are Centos7 and Windows 10.
In presentation you will get to know about:
What is DHCP?
What is static and automatic IP address?
What is BootP?
What is DHCP lease time?
What is DORA process?
Important points:
1. Command to install DHCP server is
[root@avnish ~}# yum install dhcp -y
2. In Centos7 server the DHCP configuration is stored at /etc/dhcp/dhcp.conf
3. You can edit it through visual editors ex. vi, vim, gedit.
4. To start DHCP service command is:
[root@avnish ~}# service dhcpd start
5. If you want to check the lease database to see what clients got IP
[root@avnish ~}# cat / var /lib dhcpd dhcpd.leases
