Procedure 10.1. Installing and configuring dhcpd

1. Install the dhcp server package.

   # dnf install dhcp

2. Create a simple configuration for the dhcp server at /etc/dhcp/dhcpd.conf

   subnet 192.168.1.0 netmask 255.255.255.0 {
   authoritative;
   default-lease-time 600;
   max-lease-time 7200;
   ddns-update-style none;
   
   option domain-name-servers 192.168.1.1;
   option routers 192.168.1.1;
   
   }
   

3. Test your configuration and address any problems you discover.

   systemctl start dhcpd
   journalctl --unit dhcpd --since -2m --follow
   

4. Add entries to point clients to their bootloader and the server that provides it to your subnet configuration in /etc/dhcp/dhcpd.conf. Because DHCP clients provide the server with identifying information along with their address request, BIOS clients and UEFI clients can each be directed to the correct bootloader.

   # refer to RFC4758 for possible arch option values
   option arch code 93 = unsigned integer 16;
   
   subnet 192.168.1.0 netmask 255.255.255.0 {
   if option arch = 00:07 {
   filename "uefi/shim.efi";
   } else {
   filename "pxelinux.0";
   }
   
   next-server 192.168.1.2;
   
   ...
   

5. Restart the dhcp service to check the configuration and make changes as needed.

   systemctl restart dhcpd
   journalctl --unit dhcpd --since -2m --follow
