Fedora Linux: Restart / Stop / Start DHCPD Server Command

Posted on in Categories , , last updated August 9, 2013

I am a new Fedora Linux version 18 system administrator. How do I restart dhcpd server using command line options in Fedora Linux server running on HP server hardware?

DHCP (Dynamic Host Configuration Protocol) is a protocol which allows individual devices on an IP network to get their own network configuration information such as follows from a DHCP server:

  1. IP address
  2. Subnetmask
  3. Broadcast address
  4. DNS server IP address
  5. Default gateway IP address and more

The dhcp package includes the ISC DHCP service, server and relay agent.

Fedora start / stop / restart DHCPD (latest version)

Alert: You need Fedora Linux version 15 or above to use the following commands.

To restart dhcpd service, open a terminal or login using ssh and then type:
# systemctl restart dhcpd.service
To stop dhcpd service, type:
# systemctl stop dhcpd.service
To start dhcpd service, type:
# systemctl start dhcpd.service

Note: By default, the DHCPD service does not start at boot time. To configure the daemon to start automatically at boot time, type:
# systemctl enable dhcpd.service

Fedora start / stop / restart DHCPD (older version)

Alert: You need Fedora Linux version 14 or older to use the following commands. Also, commands are compatible with RHEL/CentOS Linux too.

To restart dhcpd service, open a terminal or login using ssh and then type:
# service dhcpd restart
To stop dhcpd service, type:
# service dhcpd stop
To start dhcpd service, type:
# service dhcpd start

Note: By default, the DHCPD service does not start at boot time. To configure the daemon to start automatically at boot time, type:
# chkconfig dhcpd on
